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.

What causes tooth discoloration and which types respond best to whitening?

+

Tooth color changes for several reasons, including surface stains from coffee, tea, red wine and tobacco as well as deeper discoloration from aging, trauma or certain medications. Surface stains typically result from chromogens that adhere to enamel and are usually the easiest to lighten with peroxide-based whitening. Internal or intrinsic stains are more deeply embedded and can require longer or alternative approaches to achieve noticeable improvement.

Understanding the stain type is a key part of treatment planning because it sets realistic expectations for the degree of change possible. Yellowish discoloration often responds well to bleaching, while gray, brown or tetracycline-type stains can be more resistant and may need combined cosmetic solutions. Your dentist will evaluate enamel thickness, underlying tooth structure and existing restorations before recommending a tailored approach.

How do in-office whitening and dentist-supervised take-home systems differ?

+

In-office whitening typically uses higher-concentration peroxide agents applied under controlled conditions to produce faster results in a single visit, while take-home systems use lower-concentration gels in custom trays worn over days or weeks for gradual whitening. Both methods rely on the same oxidative chemistry but differ in concentration, exposure time and professional supervision. In many cases a combination—an in-office session followed by at-home touch-ups—provides efficient initial change and longer-lasting maintenance.

At the office of Paparian Dental Associates, clinicians evaluate oral health and personalize the protocol to balance speed of whitening with sensitivity management and safety. Dentist supervision ensures the fit of trays, appropriate product selection and clear instructions for use, which reduces the risk of uneven whitening or gum irritation compared with over-the-counter options. This oversight also enables predictable follow-up and adjustments if sensitivity or other concerns develop.

What is the science behind teeth whitening and how does it remove stains?

+

Most professional whitening products use hydrogen peroxide or carbamide peroxide, which penetrate enamel and break down pigmented molecules through oxidation. The peroxide molecules release reactive oxygen species that alter the chemical structure of stain compounds so they reflect light differently and appear lighter. The extent of whitening depends on peroxide concentration, contact time and the nature of the stain.

Clinical protocols balance concentration and exposure to maximize effect while protecting soft tissues and minimizing sensitivity. In-office treatments use higher concentrations for shorter exposures under clinician control, whereas take-home gels use lower concentrations over longer wear times. The dentist assesses enamel condition and gum health before selecting a safe, effective protocol tailored to each patient.

Am I a good candidate for professional teeth whitening?

+

Good candidates are adults with generally healthy teeth and gums who have natural tooth structure exhibiting surface or intrinsic staining. Patients with active decay, untreated gum disease, exposed roots or cracked teeth will usually be treated for those conditions first because whitening is safest and most effective on stable oral tissues. A consultation and exam allow the dentist to screen for issues that could limit results or increase sensitivity.

People with extensive restorations should discuss aesthetic goals with their clinician because crowns, veneers and composite fillings do not bleach and may need replacement or staging to match a new tooth shade. The dentist will review expectations, discuss possible outcomes and recommend alternatives if bleaching alone is unlikely to produce the desired result. Personalized planning ensures safe, predictable care aligned with each patient’s priorities.

Will whitening affect crowns, veneers or tooth-colored fillings?

+

Bleaching agents only change the shade of natural tooth structure and do not alter the color of dental restorations such as crowns, veneers or composite fillings. Because restorations remain their original shade, whitening may create a mismatch if restorations are present on visible teeth. Treatment planning therefore includes evaluating existing work and discussing whether future replacement or selective restoration is indicated after whitening.

If restoration replacement is likely, many clinicians recommend whitening first and then matching new restorations to the post-whitening shade for the most harmonious result. In other cases, blending strategies or selective touch-ups can produce an acceptable appearance without immediate restoration work. Your dentist will explain the pros and cons and help you choose an approach that balances longevity and aesthetics.

How should I prepare for a professional whitening appointment?

+

Preparing for whitening usually begins with a dental examination and professional cleaning to remove surface deposits and identify any oral health issues that should be addressed first. Treating cavities, gum inflammation or other dental problems before bleaching helps reduce the risk of sensitivity and ensures the best cosmetic outcome. The clinician will document your starting shade, discuss realistic expectations and explain the chosen protocol and aftercare instructions.

If you receive custom take-home trays, the practice will take impressions or digital scans to fabricate well-fitting devices that reduce gel leakage and gum irritation. Proper tray fit and clear instructions on wear time and frequency are essential for safe results. Be sure to disclose any history of sensitivity, allergies or medication use so the team can tailor recommendations appropriately.

Is tooth sensitivity normal after whitening and how can it be managed?

+

Mild to moderate sensitivity to hot and cold is a common, usually temporary side effect of professional whitening and tends to peak shortly after treatment before resolving within days to weeks. Sensitivity occurs because peroxide can temporarily increase fluid movement in the dentinal tubules or affect nerve responsiveness in teeth that are already prone to sensitivity. Most patients find relief with short-term measures and do not experience long-term problems.

To manage sensitivity, clinicians often recommend desensitizing toothpaste containing potassium nitrate or fluoride, shorter application times, lower-concentration gels, or spacing out treatment sessions. In-office options such as topical desensitizers or varnishes may be applied when needed, and prescription-strength products are available for persistent symptoms. Open communication with your dentist allows adjustments to the protocol that maintain safety and comfort.

What should I do after whitening to protect and prolong results?

+

Immediately after whitening, enamel is more susceptible to re-staining for about 48 hours, so avoiding concentrated pigments such as coffee, red wine, dark tea and berries during that period helps preserve gains. Using a straw for beverages, rinsing with water after consuming staining foods and practicing good oral hygiene with a soft-bristle brush and fluoride toothpaste reduce surface re-deposition. Quitting or reducing tobacco use also greatly improves long-term color stability and overall oral health.

Long-term maintenance may include periodic use of dentist-provided at-home trays with touch-up gel or occasional in-office refreshes depending on diet and staining habits. Regular professional cleanings remove surface deposits that can dull appearance and support sustained results. Your clinician at Paparian Dental Associates can recommend a personalized maintenance schedule based on your lifestyle and how quickly your teeth tend to re-stain.

Are there situations when whitening should be delayed or avoided?

+

Whitening is generally advised for healthy adult teeth; it should be postponed if there are active cavities, significant gum disease, exposed roots, or untreated dental trauma. Pregnant or breastfeeding patients are typically recommended to delay elective whitening until after pregnancy and lactation due to limited safety data. Young patients with incomplete tooth development also require careful assessment before undergoing bleaching procedures.

Certain medical conditions or medications that affect tooth structure or sensitivity can influence candidacy and protocol selection, so full disclosure of health history is important. The dentist will review your medical and dental history to determine whether whitening is appropriate or if alternative cosmetic strategies are preferable. Safety-first decision making helps protect oral tissues while achieving the best possible aesthetic result.

How often can I safely repeat professional whitening treatments?

+

The frequency of safe whitening depends on the method used, individual tooth response and lifestyle factors that contribute to re-staining. Many patients receive an initial course of treatment and then schedule touch-ups as needed, often every six months to a few years, guided by diet, tobacco use and personal preferences. Excessive or overly frequent bleaching can increase sensitivity or, in rare cases, affect enamel integrity, so treatments should be supervised by a dentist.

Your dentist will monitor outcomes and recommend an interval that balances desired shade maintenance with oral health considerations, using the lowest effective concentration and exposure time. For long-term stability, clinicians often emphasize preventive measures and targeted touch-ups rather than repeated full-strength sessions. Regular checkups provide an opportunity to reassess and safely plan any repeat whitening.
