Dental Fillings

Keeping Teeth Strong: The Role of Modern Dental Fillings

Dental fillings are more than a quick fix — they are a practical way to preserve tooth structure, restore chewing function, and stop decay from spreading. When a cavity weakens enamel and dentin, a carefully placed filling rebuilds the tooth so it can withstand daily forces and avoid further damage. Well-executed restorations protect both oral health and the long-term appearance of your smile.

Tooth decay remains a common issue across all ages, but the approach to restoring affected teeth has improved dramatically. Today's techniques focus on conservative removal of decay, precise adhesion to remaining tooth tissue, and materials that blend with your natural teeth. The goal is a restoration that is comfortable, functional, and unobtrusive.

At the office of Eliot Dental, we prioritize gentle, evidence-based care when treating cavities. We take time to explain options, evaluate the extent of decay with modern imaging tools, and select a restorative plan that balances strength, longevity, and aesthetics for each individual tooth.

A short look at how restorations evolved

Human beings have sought ways to treat damaged teeth for millennia. Early attempts at repairing or filling cavities are known from archaeological finds, and over time materials and methods changed to meet both functional and cosmetic needs. The last century alone has seen a move from metal-dominant restorations to a wide palette of tooth-colored options and laboratory-made ceramic solutions.

Understanding this history helps explain why there are multiple material choices today: each offers a specific mix of durability, appearance, and suitability for different areas of the mouth. Your treatment plan considers those trade-offs so the chosen filling performs well for years to come.

How we approach restoring a damaged tooth

Our philosophy centers on preserving as much healthy tooth as possible while removing decayed tissue and creating a stable environment for the new restoration. We assess bite forces, the location of the cavity, the size of the defect, and cosmetic concerns before recommending a specific material or technique. This ensures the final result supports both function and appearance.

How filling materials differ and why it matters

Not all fillings are created equal. Materials vary by strength, how they bond to tooth structure, resistance to wear and staining, and how naturally they look once placed. Choosing the right material depends on the tooth involved (front versus back), the extent of decay, and your expectations for appearance and longevity.

Some options are placed directly in a single visit, while others are fabricated outside the mouth and cemented later. Advances in adhesive dentistry allow more conservative preparations for many restorations, reducing the need to remove extra healthy tooth tissue.

Your dentist will review pros and cons for each suitable material and recommend an approach tailored to the location and size of the cavity, as well as your bite and oral habits. This individualized selection helps maximize the lifespan and performance of the filling.

Common restorative materials and where they work best

  • Tooth‑colored composite restorations

    Composites are resin-based materials mixed with glass or ceramic particles and available in a range of shades to match adjacent teeth. They bond to the tooth surface, which often lets the clinician conserve more natural tooth during preparation. Composites can be shaped and polished to replicate natural contours and gloss, making them a popular choice for visible areas.

    While composites provide excellent aesthetics and seal the tooth well, they can be more susceptible to wear or staining over many years compared with indirect ceramic options. Regular check-ups help determine when a replacement or touch-up may be needed.

  • Traditional amalgam restorations

    Amalgam — a silver-colored alloy — has a long track record for durability, especially in posterior teeth that endure heavy chewing forces. It is less technique-sensitive in placement than some modern restoratives and can perform well in situations where moisture control is a challenge.

    Although it does not mimic tooth color, amalgam remains a reliable option for certain cavity types, particularly in back molars where strength is the primary concern.

  • Glass ionomer materials

    Glass ionomer cements chemically bond to tooth structure and slowly release fluoride, which can help protect the restored area from recurrent decay. These materials are often used in pediatric dentistry, for small cavities near the gumline, or as interim restorations.

    Because they are generally less wear‑resistant than composite or ceramic, glass ionomers are selected where their protective benefits and gentle bonding properties outweigh the need for maximum longevity.

  • Ceramic and porcelain onlays/inlays

    Ceramic restorations are fabricated in the laboratory to precisely match the tooth's shape and color. They offer excellent aesthetics and strong wear resistance, making them an ideal choice when a conservative indirect restoration is preferred over a full crown.

    These restorations typically require two visits: one to prepare the tooth and record an impression, and a second to bond the finished piece. Their strength and color stability make them an attractive long-term solution for larger defects.

  • Precious metal restorations

    Gold and other high-quality metal alloys are durable and biocompatible choices that resist wear and maintain a precise fit over time. They are less common today for esthetic reasons but still valued for their longevity in certain clinical circumstances.

    Where appearance is not a primary concern — for example, in some posterior restorations — metal restorations remain an excellent functional option.

What to expect when treating a cavity

When decay is detected, your provider will review findings from your examination and any X-rays, describe the recommended restorative approach, and explain what to expect during the appointment. The goals are to remove diseased tissue, protect the remaining tooth, and restore proper form so you can bite and chew comfortably.

Treatment is usually performed under local anesthesia so you remain comfortable. Depending on the size and location of the cavity, a single visit is often sufficient. The dentist uses precise instruments — such as high-speed handpieces, lasers, or air abrasion devices when appropriate — to remove decay while preserving healthy tooth as much as possible.

After the tooth is prepared, the chosen material is placed and contoured to restore function and contact with adjacent teeth. The bite is checked and adjusted so your jaw moves easily without interference. If a complex, multi‑surface restoration is required, an indirect solution like an onlay may be recommended and scheduled for a follow-up visit.

For patients who feel anxious, we discuss comfort measures and can explain options that make treatment more manageable. Our aim is to deliver efficient, compassionate care while keeping you informed at every step.

Looking after a new filling: practical advice and long-term care

After a filling is placed, there are a few common experiences to expect. Numbness from local anesthesia may linger for an hour or two, so avoid chewing on the treated side until sensation returns. It's normal for a newly restored tooth to feel slightly different for a short time as your mouth adjusts to the repaired surface.

Mild sensitivity to temperature or pressure can occur after restoration but usually resolves within days to weeks. If sensitivity persists or increases, or if you notice sharp pain when biting, contact our office to arrange an evaluation. Prompt attention helps prevent minor issues from becoming more complicated.

Good oral hygiene is the best way to help fillings last. Brushing twice daily with fluoride toothpaste, flossing daily, and maintaining regular dental checkups and professional cleanings keep the surrounding teeth and gum tissue healthy. During follow-up visits, your dentist will inspect restorations for wear, margins, and integrity and recommend maintenance or replacement if necessary.

With careful home care and routine dental visits, most restorations provide many years of reliable service. If you have questions about how to care for a specific type of filling, our team will provide tailored guidance.

Summary and next steps

Fillings remain a cornerstone of conservative dental care — they repair damage, protect teeth from further decay, and restore normal function with minimal disruption. Advances in materials and bonding techniques give patients a range of durable, natural-looking options to suit different needs and preferences.

Frequently Asked Questions

Are my teeth just sensitive, or do I have a cavity?

+

If the pleasure of eating a delicious bowl of ice cream or sipping a soothing cup of tea gets overshadowed by dental pain that makes you wince; it's time to contact our office. As skilled providers of care, we'll determine what's causing your discomfort and perform the treatment required to alleviate your symptoms and get you back on the road to oral health.

What causes a cavity to develop?

+

Cavities develop because of an infectious process that causes progressive damage to tooth structure. Despite starting as a pinpoint defect on the outermost enamel layer of your tooth, untreated dental decay progressively compromises more and more healthy tooth structure as it works its way to the inner layers of your tooth.

Can I still get a cavity if my tooth already has a filling?

+

Yes, you can still develop tooth decay on other surfaces of the tooth, around the margins of an old filling, or in fewer instances, recurrent decay underneath it. For this reason, it's essential to maintain excellent oral hygiene, a diet low in sugary beverages and sweets, and be sure to visit our office for routine checkups and care. While tooth decay is second only to the common cold in frequency, it's almost entirely preventable.

Is it possible to have more than one filling done at the same visit?

+

We value the time and comfort of our patients. If cavities are located on adjacent teeth, or in the same section of your smile, it may be possible to treat more than one tooth during your visit. However, how much is done each visit depends on several factors. We keep our patients well informed and tailor every treatment plan and visit to address their unique needs.

Are silver amalgam fillings safe?

+

Addressing concerns on the presence of elemental mercury in silver fillings, the American Dental Association (ADA), The Center for Disease Control and Prevention (CDC), the FDA, and the World Health Organization have all stated that amalgam restorations do not pose a risk to health. However, individuals with allergies or sensitivities to the metals in dental amalgam are advised to pursue other restorative options.

Does it hurt to get a filling?

+

Dental fillings are performed under local anesthesia to help ensure your comfort throughout the entire procedure. The involved tooth remains completely numb for the extent of your visit. Within one or two hours after the procedure is completed, the local anesthetic will gradually wear off, and normal sensations return.

When can I eat after my visit?

+

A tooth-colored composite filling is fully hardened and set by the end of your visit. However, we may advise you to wait a couple of hours until the local anesthesia has completely worn off. This advice is to help ensure you don't accidentally bite your lip, cheek, or tongue while still numb.

How long do dental fillings last?

+

The lifetime of a dental filling varies depending on the type of material used. While popular dental materials can last a decade or more with proper care, they can degrade over time, wear down, or even break. When this happens, you may experience some tooth sensitivity, a jagged edge, or a loose or dislodged piece of filling material. Whatever the case may be, it's essential to get the filling replaced before the tooth sustains further damage or other consequences arise. Beyond taking good care of your smile to help ensure the longevity of your fillings, our office regularly checks the status of your existing fillings as part of a routine checkup exam.

How much do fillings cost?

+

Dental fillings are an essential investment that serves to preserve and protect the health of your smile. With that said, how much a filling costs depends on the number of surfaces of the tooth involved and the filling material that is used. Amalgam restorations are the most economical. While tooth-colored composite fillings have a slightly higher cost, they offer the added benefits of being metal-free and much more aesthetically pleasing. Ceramic fillings, inlays, and onlays are more expensive than the preceding options but provide outstanding, long-lasting, and natural-looking results.

Does dental insurance cover the cost of getting a filling?

+

Dental insurances typically cover the cost of dental fillings. While we work with you to maximize your insurance benefits, there may still be an out-of-pocket expense. At the office of Eliot Dental, we strive to help you begin care without any additional financial stress or delay.

What are dental fillings and why are they used?

+

Dental fillings are restorative materials placed into a tooth after decay or minor damage is removed to rebuild form and function. They stop decay from spreading, restore chewing surfaces, and help maintain proper tooth alignment and bite. Fillings also protect the inner layers of the tooth, preventing infection and the need for more extensive treatments.

Modern fillings are designed to be conservative and to bond with remaining tooth structure, which preserves more natural tissue than older methods. The goal of a filling is both functional and preventive: to restore strength and to reduce the risk of future breakdown. Your dentist will explain how a filling fits into an overall plan to maintain oral health and avoid complications.

What types of filling materials are available and how do they differ?

+

Common filling materials include tooth-colored composite resin, traditional amalgam, glass ionomer cement, and indirect ceramic or metal onlays and inlays. Each material differs in appearance, strength, wear resistance, and how it bonds to the tooth, so the choice depends on the location and size of the cavity and esthetic preferences. Composite resins match tooth color and bond to enamel, while amalgam is durable for high-stress chewing areas; glass ionomer releases fluoride and is often used near the gumline or for pediatric cases.

Indirect options such as ceramic or metal onlays are fabricated in a dental laboratory and cemented to the tooth when a larger portion of the tooth needs restoration. These indirect restorations offer excellent strength and color stability, making them a good choice for larger defects that are not best served by a direct filling. Your dentist will review the pros and cons of each material so you can choose one that balances durability and appearance for your specific situation.

How does the dentist decide which filling material is best for my tooth?

+

Choosing a material involves evaluating the tooth's location, the size and depth of the cavity, bite forces, and esthetic priorities. Posterior teeth that withstand heavy chewing may benefit from the strongest materials, while front teeth or highly visible areas often call for tooth-colored options that blend seamlessly. The dentist will also consider factors like moisture control during the procedure and any history of sensitivity or allergic reactions.

Diagnostic tools such as X-rays and intraoral imaging help determine how much natural tooth remains and whether a conservative filling is appropriate or an indirect restoration is preferable. Your personal oral habits, such as grinding or clenching, influence material selection because these habits increase wear and stress on restorations. A tailored recommendation aims to maximize the restoration's lifespan while preserving tooth structure and appearance.

What happens during a typical filling appointment?

+

A typical filling appointment begins with a clinical exam and review of any necessary X-rays to evaluate the extent of decay or damage. Local anesthesia is administered to keep you comfortable while the dentist removes the decayed tissue and shapes the cavity to receive the filling. The prepared surface is cleaned and treated according to the chosen material's protocol, which may include bonding agents for composites or placement techniques specific to glass ionomer or amalgam.

For direct fillings like composites, the material is placed in layers, shaped, and cured with a light to achieve proper contour and contact with neighboring teeth. If an indirect restoration is required, the dentist will take an impression or digital scan and place a temporary restoration before scheduling a follow-up to cement the final piece. Throughout the visit the clinician checks your bite and makes any necessary adjustments to ensure comfort and proper function.

What should I expect after a filling is placed?

+

After a filling, it is common to experience numbness from local anesthesia for an hour or two, so avoid chewing until sensation returns to prevent accidental biting of soft tissues. Mild sensitivity to hot, cold, or pressure can occur for several days or weeks as the tooth adjusts to the restoration, and this typically resolves on its own. If sensitivity worsens or sharp pain is felt when biting, contact the office so the dentist can evaluate the restoration and rule out underlying issues.

Maintaining good oral hygiene and avoiding very hard foods immediately after placement help the filling settle and reduce stress on the new restoration. Your dentist will review any special instructions based on the material used and may recommend a follow-up visit to confirm the filling's integrity. Prompt attention to unusual symptoms helps prevent minor problems from escalating into more extensive treatment needs.

How can I care for my fillings to help them last?

+

Fillings last longer when you practice good oral hygiene: brush twice daily with fluoride toothpaste, floss daily, and keep regular dental checkups for professional cleanings and examinations. Limiting highly acidic foods and minimizing habits that stress teeth, such as chewing ice or opening packages with your teeth, reduces wear and the risk of chipping or fracture. If you grind or clench your teeth, discuss protective options like a nightguard to shield restorations from excessive force.

During routine dental visits the clinician inspects fillings for signs of wear, marginal breakdown, or secondary decay and recommends maintenance or replacement when needed. Early detection of issues allows for simpler repairs and protects surrounding tooth structure. The team at Eliot Dental can provide personalized care tips to preserve restorations and support overall oral health.

What signs indicate I might need a new or replacement filling?

+

Signs that a filling may need attention include persistent sensitivity, a sharp or shooting pain when biting, visible cracks or rough edges on the restoration, and recurrent decay around the filling margin. You might also notice a change in how a tooth feels when you bite or chew, or discoloration at the edge of the filling. Any of these symptoms warrant an evaluation because small issues can progress to deeper decay or damage if left unchecked.

During examinations and X-rays your dentist checks for recurrent decay, leakage, and structural weakness that can compromise a filling. If a filling is failing, the clinician will recommend the most conservative repair possible, whether that is a replacement filling, an indirect onlay, or another restorative approach suited to the condition. Timely assessment helps preserve tooth structure and avoid more invasive treatments.

Are dental fillings safe, and what should I know about amalgam?

+

Dental fillings are generally safe and are fabricated from materials with long histories of clinical use; regulatory and professional organizations monitor their safety and effectiveness. Amalgam contains a small amount of elemental mercury combined with other metals, and while it is durable and effective for many patients, alternatives such as composites and ceramics are widely available for those who prefer tooth-colored options. Your dentist will discuss material properties, potential risks, and suitability for your specific clinical needs so you can make an informed choice.

If you have specific health concerns—such as a known allergy to a restorative material or pregnancy-related questions—bring these up during your consultation so the dental team can adjust the treatment plan accordingly. Many practices, including Eliot Dental, prioritize evidence-based information and patient preferences when recommending restorative options. Open communication ensures you receive a safe, appropriate restoration tailored to your overall health and oral condition.

When is an onlay, inlay, or crown a better choice than a filling?

+

An onlay, inlay, or crown is often recommended when a cavity involves a large portion of the tooth or when existing structure is too compromised for a direct filling to provide reliable long-term support. Indirect restorations are fabricated to precisely fit the prepared tooth and can offer greater strength, better occlusal stability, and improved longevity for larger defects. They are particularly useful when the remaining tooth walls need reinforcement or when aesthetics and color stability are high priorities.

The decision between a direct filling and an indirect restoration depends on factors such as the amount of healthy tooth left, functional demands, and the likelihood of future fracture. Your dentist will use clinical examination and imaging to determine the best approach and will explain why a conservative indirect restoration might be recommended. Choosing the right option at the outset helps reduce the need for more extensive treatment later on.

How are fillings different for children compared to adults?

+

Fillings for children take into account the anatomy of primary teeth, behavior and cooperation, and the expected lifespan of the tooth before natural exfoliation. Materials such as glass ionomer are often used in pediatric dentistry because they chemically bond to tooth structure, release fluoride, and can be placed in situations where moisture control is challenging. Composite resins and stainless steel crowns are also common in pediatric care for their durability and ability to restore function effectively.

Pediatric treatment plans focus on preserving oral health while minimizing discomfort and appointment length, and preventive measures like fluoride varnish and sealants may accompany restorative care. Parents are encouraged to discuss sedation options and behavioral strategies with the dental team to ensure a positive experience. The office of Eliot Dental strives to tailor pediatric restorations to each child's needs while promoting long-term oral health and proper development.
