Teeth Whitening

A teeth whitening procedure or bleaching simply refers to any process that will make the teeth appear whiter. It is considered a non-invasive procedure that is designed to whiten and brighten teeth that are stained, discolored, darkened, or yellowed. First introduced to the public in the 1980’s, the popularity of teeth whitening products and procedures has soared. According to a survey conducted by the American Academy of Cosmetic Dentistry, when respondents were asked, “What would you like to improve most about your smile?” The most common response was: whiter and brighter teeth.

How white a tooth appears depends upon how light is reflected and scattered off the enamel, the outermost layer of the tooth. Teeth can look dark or discolored for a variety of reasons, with an imperfect appearance the result of outer surface stains or discoloration from within the tooth. While external tooth stains are typically due to certain foods and tobacco, internal tooth discoloration is mainly the result of hereditary factors, certain medications, tooth decay, restorations, or trauma. Additionally, the aging process can influence the color of a tooth. This is because over time the outer layer of enamel becomes thinner showing more yellowish tones from the underlying layer of dentin.

What are the advantages of a professional teeth whitening procedure performed by a dentist?

Although over the counter teeth whitening systems purchased in stores or online have become popular, there are health concerns and limitations with these products. If the manufacturers protocol is not correctly followed, certain products can damage the teeth and soft tissues in the mouth, and may not deliver the results as promised. Teeth whitening systems contain varying concentration of either hydrogen peroxide or carbamide peroxide, which act as the bleaching agents. When sensitive teeth, exposed roots, cavities, broken fillings, cracked teeth, or loose dental work are present, a teeth whitening procedure may be contraindicated. Also, since whitening systems do not have an effect on the color of dental fillings, crowns or bridges the presence of restorations is an important cosmetic consideration in treatment planning.

In general, individuals with yellow tones to their teeth respond best to teeth whitening procedures. Brown and grayish tinted teeth bleach respond less well and may require significantly longer dentist supervised tooth whitening regimens or alternative cosmetic treatments. Finally, teeth whitening may not be recommended in the presence of sensitive teeth, worn enamel and significant gum disease.

As a rule the healthiest and most effective methods of teeth whitening are the ones managed and supervised by the dentist. An in-office teeth whitening procedure as performed by the dentist is the most reliable and safest way to get the maximum results quickly. In as little as one hour a prescription-strength, in-office whitening procedure can dramatically whiten and brighten the natural teeth by several shades, while the surrounding tissues and any sensitive areas of the teeth are carefully isolated and protected from the bleaching agents.

A home whitening system from the dentist along with custom trays that have been fitted to the teeth is also an excellent option. Custom trays keep the bleaching agent in maximum contact with the teeth and away from the other areas of the mouth. With a take-home teeth whitening system, maximum results are less rapid than an in office procedure and are typically achieved over a longer period of time. A home whitening system can be used by itself or as recommended by the dentist as a follow up to an in office procedure in order to perfect or maintain the results.

Frequently Asked Questions

What's the best way to whiten my smile?

+

While an overwhelming selection of over-the-counter teeth whitening products is readily available for purchase at stores or online, it's imperative to keep in mind that the healthiest and most effective methods of care are those professionally supervised by your dentist. With a teeth whitening procedure provided by our office, we can safely, comfortably, and effectively transform your smile by up to several shades in a short amount of time.

How does a teeth whitening work?

+

Teeth whitening offers a simple and non-invasive way to whiten and brighten your smile. Whitening products contain various strengths of biologically safe hydrogen peroxide or carbamide peroxide that act as bleaching agents on stained or discolored dental enamel. By breaking the stains into smaller pieces, these bleaching agents make the color less concentrated and your teeth brighter.

Is teeth whitening painful?

+

Every patient is different, and despite the fact that many people experience no sensitivity or pain with a professional teeth whitening, there are some that do. Although considered a minimally invasive cosmetic procedure, some temporary discomfort during and following the procedure may ensue. It helps to stick to room temperature beverages for a few days following a teeth whitening. You can also take over-the-counter pain medication as you would for a headache. If you have a history of sensitive teeth, we may select a gentler formulation of whitening products or an alternative procedure.

Does a teeth whitening procedure work for all types of stains and discolorations?

+

It's essential to keep in mind that every patient has unique needs and specific requirements of care. In general, individuals with yellow tones to their teeth respond best to teeth whitening. Brown and grayish tinted teeth respond less well to bleach and may require significantly longer dentist-supervised tooth whitening regimens or alternative cosmetic treatments. Finally, teeth whitening may not be recommended in the presence of sensitive teeth, worn enamel, and significant gum disease.

What if my teeth are darkly stained?

+

For darkly stained teeth, a whitening procedure may not provide the cosmetic results desired. In these cases, we'll talk about alternative options such as porcelain veneers or full-coverage crowns.

Will a tooth whitening procedure work on crowns, veneers, bonding, or tooth-colored fillings?

+

Teeth whitening only works on natural teeth. The fact that whiteners do not affect the color of existing dental fillings, veneers, bonding, crowns, or bridges on the front teeth remains an important consideration when choosing the best cosmetic option in care.

Is teeth whitening safe?

+

As a rule, the healthiest and most effective methods of teeth whitening are the ones managed and supervised by your dentist. You can count on our office to provide the most effective, safest, and satisfying professional-strength options to whiten, brighten, and lighten your smile! Stay away from over-the-counter products, which may be overly abrasive or put the health of your teeth and the surrounding soft tissues at risk. While these products may work when healthy teeth and gums are present, they're often ineffective or problematic when sensitive teeth, exposed roots, cavities, broken fillings, cracked teeth, or loose dental work are the case.

How long do the results of teeth whitening last?

+

How long your teeth whitening lasts depends on your lifestyle. Your eating, drinking, and smoking habits can have a significant impact on maintaining your result. Of course, the best way to ensure that your smile stays healthy and beautiful is a good daily oral healthcare regimen, along with regular dental checkups and cleanings.

Does dental insurance cover teeth whitening procedures?

+

It's essential to keep in mind that as a cosmetic dental procedure, a teeth whitening may not be covered by your insurance plan. We understand the financial considerations involved in care and do our best to help you get the treatment you need without any additional stress or delay. We offer several payment options and financing plans to make things easier.

Why choose the office of Eliot Dental

+

At the office of Eliot Dental, we want every patient to enjoy the benefits of a smile that is as beautiful as it is healthy. In addition to offering a comprehensive range of advanced services to keep your smile in tip-top health, we also provide leading-edge cosmetic solutions to transform less-than-perfect-looking teeth into ones that dazzle.

What is professional teeth whitening and how does it differ from over-the-counter products?

+

Professional teeth whitening is a dentist-supervised process that uses higher-concentration bleaching agents and custom delivery methods to lighten tooth color more effectively than most store-bought options. At the office of Eliot Dental we use professional-strength hydrogen peroxide or carbamide peroxide formulations that are selected and applied based on your dental health and cosmetic goals. These systems are administered under clinical supervision to maximize results while protecting soft tissues and minimizing complications.

Over-the-counter products such as strips, toothpastes, and rinses typically contain lower concentrations of bleaching agents and deliver less predictable results. Because professional care includes an exam and custom trays or in-office application, treatment can be tailored and adjusted for sensitivity, existing restorations, and the type of staining. In many cases professionally supervised whitening achieves faster, stronger, and longer-lasting whitening than unsupervised home remedies.

What causes tooth discoloration and staining?

+

Tooth discoloration can originate from external staining or internal changes within the tooth structure. External stains are usually caused by foods and beverages like coffee, tea, red wine, berries, and tobacco use, which deposit pigments on the enamel surface, while internal discoloration can result from aging, certain medications, trauma, tooth decay, or changes in dentin.

Enamel naturally thins with age, allowing the yellowish dentin beneath to show through and alter overall tooth color. Different types of staining respond differently to whitening, so a proper dental evaluation helps determine whether bleaching, restorative work, or a combination of treatments will provide the best cosmetic improvement.

Am I a good candidate for teeth whitening?

+

Good candidates for teeth whitening are adults with generally healthy teeth and gums, free from active decay or significant periodontal disease. We evaluate the mouth for cavities, exposed root surfaces, cracked teeth, and unstable restorations before recommending whitening because these conditions can increase sensitivity or lead to uneven results.

Some types of discoloration, such as intrinsic stains from certain medications or very dark gray tones, may respond less predictably to bleaching and could require alternative cosmetic options like veneers or bonding. A dental exam will help determine the safest and most effective approach tailored to your smile.

How do in-office whitening and take-home whitening kits work?

+

Both in-office whitening and take-home kits rely on peroxide-based bleaching agents that penetrate enamel to oxidize and break apart stain molecules, making teeth appear lighter. In-office treatments typically use higher concentrations of hydrogen peroxide and are applied by the dental team for a controlled, faster result, while take-home kits use lower concentrations in custom-made trays that you wear for a prescribed period.

Custom trays provide even contact between the gel and tooth surfaces, which improves effectiveness compared with generic store-bought trays. Your dentist will recommend the appropriate system based on the shade change desired, sensitivity history, and practical considerations like treatment duration and maintenance.

Are teeth whitening treatments safe and what side effects should I expect?

+

When performed under dental supervision, teeth whitening is considered safe for most patients, but some temporary side effects can occur. The most common issues are transient tooth sensitivity and mild gum irritation, both of which usually resolve within a few days after treatment ends.

Your dentist can minimize risks by screening for oral health problems before treatment and by recommending desensitizing protocols such as lower-concentration gels, shorter application times, or the use of potassium nitrate or fluoride products. If sensitivity or irritation persists beyond a short recovery period, contact your dental provider for evaluation and follow-up care.

How long do whitening results typically last and what affects longevity?

+

Whitening results can last from several months to a few years depending on individual habits and oral health practices. Factors that shorten longevity include frequent consumption of staining foods and beverages, smoking, poor oral hygiene, and certain medications that contribute to discoloration.

Maintaining results involves good daily hygiene, regular professional cleanings, and lifestyle choices that limit staining, such as using a straw for dark beverages and rinsing or brushing after pigmented foods. Your dentist may also provide or recommend periodic touch-up treatments with a take-home kit to refresh results as needed.

Will whitening change the color of my crowns, veneers, or fillings?

+

Teeth whitening only affects natural tooth structure and does not change the shade of dental restorations such as crowns, veneers, bridges, or composite fillings. Because restorations are color-stable, whitening natural teeth first and then matching or replacing restorations is often the best strategy when the appearance of restorations is a concern.

If you are planning whitening and have visible restorations, discuss this with your dentist so they can advise on sequence and timing, and on the potential need to update restorations to match your new tooth shade for a uniform result.

How should I prepare for a teeth whitening appointment?

+

Before a whitening appointment you should have a recent professional cleaning and any active dental issues addressed, such as cavities or gum disease. Arriving with healthy teeth and gums helps prevent complications and ensures more even, predictable whitening outcomes.

Tell your dental team about tooth sensitivity, recent dental work, and any medications you take, and follow any pre-treatment instructions provided by your dentist. Simple preparation steps like brushing and flossing before your visit improve comfort and allow the team to assess your shade and tailor the treatment plan.

What aftercare steps should I follow to protect my whitening results?

+

After whitening you should avoid highly pigmented foods and beverages for at least 48 hours and minimize consumption of staining substances such as coffee, tea, red wine, dark sodas, and berry sauces. Using a straw for colored drinks, rinsing with water after eating, and waiting to brush immediately after treatment can help protect the freshly treated enamel.

Maintaining good oral hygiene, attending regular dental cleanings, and following any take-home maintenance plan recommended by your dentist will prolong results. If touch-ups are advised, your dental team can provide custom trays and a regimen to help you maintain a bright, natural-looking smile at home.

How can I manage sensitivity during or after whitening?

+

Sensitivity during or shortly after whitening is common and usually temporary, caused by changes in fluid movement within the tooth tubules following bleaching. To manage sensitivity, your dentist may suggest using desensitizing toothpaste containing potassium nitrate or fluoride, applying fluoride varnish in the office, or shortening the duration of bleaching applications.

If sensitivity is significant, pause treatment and consult your dental provider to adjust the protocol or explore alternative options that reduce discomfort. Long-term or severe sensitivity is uncommon, but prompt communication with your dentist ensures safe care and a plan that balances comfort with cosmetic goals.
