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 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 Hearth Dental Practice?

+

At the office of Hearth Dental Practice, 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 whitening options are available at your practice?

+

We offer both in-office and dentist-prescribed take-home whitening options that use professional-strength bleaching agents chosen for clinical needs. In-office treatments allow for controlled, accelerated shade improvement during a single visit, while take-home systems use custom trays and lower-concentration gels for gradual, even whitening over days or weeks. Some patients follow an in-office session with at-home maintenance to extend and refine their results.

Every treatment begins with a clinical evaluation so the method matches your oral health and cosmetic goals. We consider factors such as stain type, tooth sensitivity, and existing restorations before recommending a plan. That individualized approach helps maximize results while minimizing side effects like irritation or excessive sensitivity.

How do in-office and take-home whitening treatments differ?

+

In-office whitening uses higher concentrations of bleaching agents under professional supervision to deliver faster, more dramatic shade changes in a short appointment. These sessions are performed with soft-tissue protection and monitored applications, and may include brief, repeated gel activations to achieve several shades of improvement. Because the process is concentrated, we carefully manage sensitivity and adjust protocols in real time.

Take-home whitening uses custom-fitted trays and lower-strength gel that you wear for prescribed intervals at home, producing gradual, controlled lightening. This method is often gentler on sensitive teeth and gives you greater control over pace and outcomes. Many patients prefer take-home systems for convenience and for periodic touch-ups after an in-office treatment.

Am I a good candidate for teeth whitening?

+

Candidates for whitening generally have good overall oral health, with cavities treated and gum disease under control prior to starting bleaching. Whitening is most effective for extrinsic stains caused by foods, drinks or tobacco, and for some age-related discoloration that results from enamel wear. Patients with widespread decay, active periodontal problems, or untreated restorations should address those issues first to avoid uneven results or irritation.

Certain situations may require special consideration: teeth with intrinsic discoloration, some medications-related staining, or very thin enamel may respond unpredictably to bleaching. Pregnant or nursing patients are commonly advised to postpone elective whitening until after pregnancy, and younger patients are assessed on a case-by-case basis. A consultation clarifies whether whitening or an alternative cosmetic approach is the best path.

How should I prepare for a whitening appointment?

+

Before whitening begins we perform a thorough dental exam and recommend a professional cleaning if plaque or surface staining is present. Any active decay, loose restorations, or untreated gum issues should be addressed first because these can cause discomfort or uneven whitening results if left unresolved. We also document your current shade and discuss realistic expectations so you understand the likely outcome.

For take-home systems we will take impressions for custom trays and give detailed instructions on application, wear time and storage of the materials. If you have a history of tooth sensitivity, we may recommend desensitizing toothpaste or modify the protocol to reduce discomfort. Clear communication about your dental history and habits helps us tailor a safe, effective plan.

Will whitening damage my enamel or existing dental work?

+

When performed under professional supervision, whitening is considered safe and does not permanently damage tooth enamel in healthy teeth. Clinical oversight lets us select appropriate concentrations and wear times and to treat underlying issues that could increase risk, such as enamel defects or exposed root surfaces. Temporary sensitivity or mild gum irritation can occur, but these effects typically resolve after treatment and are managed with conservative measures.

It is important to know that restorations such as crowns, veneers, fillings and bonding do not whiten with bleaching agents. If restorations are visible when you smile, we will review options to harmonize their shade with your natural teeth after whitening or consider restorative alternatives when needed. This planning prevents mismatched colors and ensures an aesthetic, long-lasting result.

How can I manage sensitivity during and after whitening?

+

Sensitivity is the most common side effect of whitening, and we take steps to reduce it before, during and after treatment. Strategies include using lower-concentration gels for at-home wear, shortening application times, applying desensitizing agents before treatment, and recommending a toothpaste formulated for sensitive teeth. For in-office procedures we monitor comfort and can pause or adjust the protocol if sensitivity increases.

If sensitivity appears after treatment, simple measures such as avoiding very hot or cold foods for a short period and using desensitizing toothpaste often relieve symptoms. In persistent cases we may prescribe a professional desensitizing gel or alter future sessions to minimize discomfort. Our goal is to achieve a brighter smile while keeping you comfortable throughout the process.

How long do whitening results last and what maintenance is required?

+

Longevity varies by individual and depends on diet, oral hygiene, and habits such as smoking or frequent consumption of staining beverages. Many patients enjoy noticeable whiteness for months to years with good maintenance, and periodic touch-ups with dentist-prescribed gels or brief in-office visits help sustain shade. The initial 48 hours after whitening are especially important to avoid re-staining, so choosing lighter foods and rinsing after colored beverages reduces early relapse.

Ongoing preventive care—regular cleanings, daily brushing and flossing, and moderating stain-causing foods—extends the life of whitening results. We will recommend a maintenance schedule tailored to your lifestyle and the degree of improvement you seek. Regular dental visits also let us monitor tooth color and advise timely refresh treatments as needed.

What options exist if my teeth do not respond well to bleaching?

+

Some types of intrinsic staining, such as discoloration from certain medications or deep staining from trauma, respond poorly or inconsistently to bleaching. In these cases we discuss alternative cosmetic approaches that can reliably improve appearance, including bonding, porcelain veneers, or targeted restorative replacement. These options address color as well as shape and surface defects when whitening alone is unlikely to meet expectations.

A clinical evaluation helps determine whether additional or alternative treatments are necessary and which approach best balances conservatism with aesthetic goals. We explain the pros and cons of each option and create a plan that preserves tooth structure whenever possible. Open discussion about anticipated results ensures you choose a predictable solution for your smile.

How does whitening affect crowns, veneers and fillings?

+

Dental restorations do not change color with bleaching agents, so whitening natural teeth can create a mismatch with existing crowns, veneers or tooth-colored fillings. If restorations are in visible areas, we will plan treatment so restorative work is coordinated with whitening—either by replacing restorations after whitening or by selecting alternative cosmetic strategies that account for their presence. This coordination preserves a unified, natural-looking smile.

Before beginning any whitening regimen we assess the condition and shade of restorations and discuss expectations for how they will appear afterward. For patients considering future restorative work, whitening first helps the dentist match new restorations to the lightened natural teeth. Careful sequencing and planning avoid surprises and help you achieve the most harmonious outcome.
