Get Your Brighter Smile TodayEverything You Need to Know About Teeth Whitening
A bright, white smile can boost your confidence and make a powerful first impression. At Best Dental, we offer professional teeth whitening solutions that deliver dramatic results safely and effectively. Whether you're preparing for a special event or simply want to refresh your smile, understanding your whitening options helps you make the best choice.
Professional teeth whitening differs significantly from over-the-counter products in terms of strength, safety, speed, and results. This comprehensive FAQ guide answers the most common questions we receive about teeth whitening, from how it works to maintaining your results long-term.
Teeth Whitening Basics
How does teeth whitening work?
Professional teeth whitening uses bleaching agents—typically hydrogen peroxide or carbamide peroxide—to break down stains into smaller, less concentrated pieces. These agents penetrate the porous enamel and reach the dentin layer beneath, where most staining occurs. Oxygen molecules from the peroxide react with discolored molecules in your teeth, breaking the bonds that hold them together. The result is teeth that reflect more light and appear whiter. Professional whitening uses higher concentrations than over-the-counter products, delivering faster and more dramatic results under controlled conditions.
What types of teeth whitening do you offer?
Best Dental offers several professional whitening options to fit different needs and lifestyles. In-office whitening delivers the fastest results, brightening your teeth 6-10 shades in a single 60-90 minute appointment using high-concentration gel and specialized light activation. Take-home custom tray whitening provides gradual whitening over 1-2 weeks using professional-strength gel in custom-fitted trays made specifically for your teeth. We also offer combination treatments that begin with an in-office session followed by take-home maintenance trays for optimal, long-lasting results. During your consultation, we'll recommend the best option based on your goals, timeline, and budget.
Am I a good candidate for teeth whitening?
Most people with healthy teeth and gums make excellent whitening candidates. Ideal candidates have yellow or brownish stains from aging, food, coffee, tea, wine, or tobacco. Whitening works best on natural tooth enamel—it won't change the color of dental crowns, veneers, fillings, or bonding. You're not an ideal candidate if you have severe tooth sensitivity, untreated cavities, gum disease, or are pregnant or nursing. Gray stains from certain medications like tetracycline respond less predictably to whitening. We'll evaluate your oral health during a comprehensive exam before recommending whitening.
Is professional whitening better than store-bought products?
Professional whitening offers significant advantages over drugstore products. Professional treatments use higher concentrations of bleaching agents (25-40% hydrogen peroxide versus 3-10% in over-the-counter products), delivering dramatically better results in less time. Custom trays ensure even coverage and prevent gel from irritating your gums, while one-size-fits-all strips often miss areas between teeth. Professional supervision means we can address sensitivity issues immediately and protect existing dental work. While over-the-counter products cost less initially, professional whitening proves more cost-effective long-term due to superior, longer-lasting results. Most patients achieve their desired shade in one professional session compared to weeks or months with drugstore products.
Cost, Timing & Results
How much does professional teeth whitening cost?
Professional teeth whitening at Best Dental typically ranges from $300 to $800 depending on the method selected. In-office whitening treatments usually cost $500-$800 and include a single session that brightens your smile 6-10 shades. Take-home custom tray kits range from $300-$500 and include custom trays plus professional-strength whitening gel for 1-2 weeks of treatment. Combination packages that include both in-office treatment and take-home maintenance trays offer the best value. While professional whitening costs more upfront than drugstore products, the superior results, faster treatment time, and professional supervision justify the investment for most patients.
Does dental insurance cover teeth whitening?
Most dental insurance plans classify teeth whitening as a cosmetic procedure and don't provide coverage. However, some dental discount plans or certain employer-sponsored benefits packages may offer partial reimbursement or discounted rates for whitening. We recommend checking with your insurance provider directly. Even without insurance coverage, Best Dental offers competitive pricing and flexible payment options to make professional whitening affordable. Many patients also use Health Savings Accounts (HSA) or Flexible Spending Accounts (FSA) to pay for whitening with pre-tax dollars.
How long does teeth whitening take?
Treatment time varies by method. In-office whitening delivers complete results in a single 60-90 minute appointment—perfect for busy schedules or upcoming events. Take-home custom tray whitening requires wearing the trays 30 minutes to 2 hours daily for 1-2 weeks, allowing you to whiten on your schedule. Some patients prefer gradual whitening to minimize sensitivity. Combination treatments start with a quick in-office session for immediate results, followed by take-home maintenance. Regardless of method, you'll notice improvement after the first treatment, with full results visible within 1-2 weeks.
How white will my teeth get?
Results vary based on your starting shade, the type of staining, and the whitening method used. Most patients achieve 6-10 shades whiter with professional in-office treatment, and 4-8 shades whiter with take-home trays. Yellow and brown stains respond best to whitening, while gray stains from aging or medications are more stubborn. Teeth naturally have varying shades—we'll help you achieve a bright, natural-looking result that complements your complexion. Using a shade guide during your consultation, we'll discuss realistic expectations for your specific case and show you before-and-after photos of similar patients.
How long do whitening results last?
Professional whitening results typically last 1-3 years with proper maintenance, though individual results vary based on lifestyle habits. Coffee, tea, red wine, dark sodas, berries, and tobacco products cause stains to return faster. Excellent oral hygiene—brushing twice daily, flossing, and regular professional cleanings—helps maintain your bright smile longer. Most patients enjoy their results for at least a year before noticing gradual darkening. Periodic touch-ups using your custom take-home trays (usually 1-2 times per year) easily restore your original whiteness. We provide touch-up gel refills at a reduced cost for existing patients.
Safety & Side Effects
Is teeth whitening safe?
Yes, professional teeth whitening is extremely safe when performed or supervised by a dentist. Decades of research and millions of successful treatments confirm the safety of peroxide-based whitening for tooth enamel and overall oral health. Professional supervision ensures the correct concentration is used, your gums and soft tissues are protected, and any existing dental problems are addressed before whitening. At Best Dental, we customize treatment based on your oral health, tooth sensitivity, and desired results. The American Dental Association recognizes professionally administered teeth whitening as safe and effective when appropriate protocols are followed.
Will whitening damage my teeth or enamel?
Professional teeth whitening does not damage tooth enamel when properly performed. Research shows that approved whitening agents temporarily increase enamel porosity during treatment, but the enamel completely remineralizes and returns to normal hardness within days. Any temporary softening is reversible and doesn't weaken teeth structurally. However, improper use of whitening products—such as using trays that don't fit properly or exceeding recommended treatment times—can cause problems. This is why professional supervision is important. We ensure your whitening is safe, effective, and won't harm your teeth or gums.
Will my teeth be sensitive after whitening?
Temporary tooth sensitivity is the most common side effect of teeth whitening, affecting about 60% of patients. Sensitivity typically manifests as brief, sharp pain when consuming hot, cold, or sweet foods and drinks. This occurs because the whitening agent temporarily increases enamel porosity, allowing temperature and certain substances to reach the nerves more easily. Sensitivity usually appears during treatment and resolves within 24-72 hours after completion. We minimize sensitivity by using desensitizing gels, adjusting treatment duration, recommending sensitivity toothpaste before and after whitening, and customizing the peroxide concentration. Patients with existing sensitivity may need a modified protocol.
Can teeth whitening cause permanent damage?
When performed correctly under professional supervision, teeth whitening does not cause permanent damage. Temporary side effects like sensitivity or mild gum irritation resolve quickly. However, excessive or improper whitening—particularly with unsupervised high-concentration products or ill-fitting trays—can potentially damage enamel or cause chronic sensitivity. This is why we don't recommend internet-purchased bleaching kits or DIY whitening methods. Professional oversight ensures you achieve beautiful results safely without risking your oral health. We'll develop a whitening plan appropriate for your teeth and monitor your progress throughout treatment.
Are there any side effects besides sensitivity?
Besides temporary sensitivity, some patients experience mild gum irritation if whitening gel contacts the gum tissue, causing temporary whitening or slight soreness that resolves within 24 hours. Proper tray fit and careful application prevent this issue. Some people notice throat irritation if they accidentally swallow small amounts of gel—this is harmless but unpleasant. Rarely, patients report temporarily increased thirst or a slightly altered taste perception that resolves quickly. All these effects are minor, temporary, and easily managed. Serious side effects are extremely rare with professional supervision. We'll discuss your medical history and any concerns before beginning treatment.
Special Situations & Concerns
Can I whiten my teeth if I have crowns or veneers?
Teeth whitening only affects natural tooth enamel—it won't change the color of crowns, veneers, fillings, or bonding. If you have visible restorations in your smile zone, whitening your natural teeth may create a mismatch, making the restorations appear darker or more noticeable. In these cases, we'll develop a comprehensive plan, potentially whitening your natural teeth first, then replacing restorations to match your new brighter shade. If your restorations are already satisfactory, we may recommend alternatives like Lumineers or new veneers for a uniformly bright smile.
Will whitening work on tetracycline stains?
Tetracycline staining—gray or brown bands caused by antibiotic use during tooth development—presents a whitening challenge. These deep stains often respond poorly to traditional whitening, though some lightening is possible with extended treatment using custom trays and lower-concentration gel worn for longer periods (sometimes 3-6 months). Results are unpredictable and rarely achieve dramatic improvement. For severe tetracycline staining, we often recommend porcelain veneers as a more reliable solution. During your consultation, we'll examine your specific staining pattern and discuss realistic expectations or alternative cosmetic options if whitening is unlikely to deliver satisfactory results.
Can I whiten my teeth if I'm pregnant or nursing?
While there's no definitive evidence that teeth whitening harms pregnant or nursing mothers or their babies, we recommend postponing elective cosmetic procedures including teeth whitening until after pregnancy and nursing. This precautionary approach avoids any potential risk, however small. Hormonal changes during pregnancy often increase gum sensitivity and inflammation, which could make whitening more uncomfortable. Most obstetricians and pediatricians advise avoiding unnecessary chemical exposures during this time. Focus on maintaining excellent oral hygiene with regular brushing, flossing, and professional cleanings, then schedule whitening after your baby is born and you've finished nursing.
At what age can someone get their teeth whitened?
We generally recommend waiting until permanent teeth are fully erupted and mature before whitening, typically around age 14-16. Children and young teenagers have larger pulp chambers (nerve spaces) that make teeth more sensitive to whitening agents. Additionally, newly erupted permanent teeth have thinner, more porous enamel that's more vulnerable to sensitivity. There's no upper age limit for whitening—patients in their 70s and 80s successfully whiten their teeth regularly. The determining factors are oral health and tooth sensitivity, not age itself. For teenagers interested in whitening, we'll evaluate their dental development and can often recommend gentler whitening options if appropriate.
What about whitening sensitive teeth?
Patients with naturally sensitive teeth can still whiten successfully with the right approach. We recommend starting with lower-concentration whitening gel, shorter application times, and using desensitizing agents before and after treatment. Sensitivity toothpaste containing potassium nitrate used for 2 weeks before whitening significantly reduces discomfort. During treatment, we may suggest alternating whitening days with off days to allow teeth to recover. Some patients tolerate custom tray whitening better than in-office treatments because they can control the timing and intensity. If sensitivity is severe, we'll explore alternative cosmetic dentistry options that don't involve bleaching agents.
Maintaining Your Results
How do I maintain my white teeth after treatment?
Maintaining your bright smile requires good oral hygiene and smart lifestyle choices. Brush twice daily with whitening toothpaste, floss daily, and attend regular professional cleanings every six months to remove surface stains. Minimize consumption of staining beverages like coffee, tea, red wine, and dark sodas—or use a straw when drinking them to minimize contact with front teeth. Rinse your mouth with water after consuming staining foods. Quit smoking or using tobacco products, as these cause rapid re-staining. Periodic touch-ups with your custom trays (usually 1-2 times per year) easily maintain your results. We provide touch-up gel refills at a reduced cost.
What foods and drinks should I avoid after whitening?
For the first 48 hours after whitening, teeth are more porous and susceptible to staining, so avoid deeply colored foods and beverages. Stay away from coffee, tea, red wine, dark sodas, berries, tomato sauce, soy sauce, balsamic vinegar, curry, and dark chocolate. Also avoid tobacco products. Stick to lighter-colored foods like chicken, fish, white rice, pasta with white sauce, bananas, white cheese, and clear liquids. After this initial period, you can resume normal eating but should minimize staining substances to prolong your results. Using a straw for colored beverages and rinsing your mouth after eating pigmented foods helps maintain whiteness long-term.
How often do I need touch-ups?
Touch-up frequency depends on your lifestyle habits and how well you maintain your results. Most patients need touch-ups every 6-12 months to maintain optimal whiteness. Coffee drinkers, wine enthusiasts, and smokers typically need more frequent touch-ups (every 4-6 months). Non-smokers who avoid staining beverages may go 1-2 years before needing a touch-up. Your custom take-home trays make touch-ups easy and affordable—simply purchase whitening gel refills and wear your trays for 1-3 nights to restore your bright smile. We'll provide personalized recommendations based on your habits and show you how to recognize when a touch-up is needed.
Will my teeth stay white permanently?
Teeth whitening results are long-lasting but not permanent. Teeth naturally accumulate new stains over time from food, drinks, aging, and other factors. Think of whitening like painting a room—the paint doesn't wear off, but walls gradually become dingy and need refreshing. With proper maintenance and periodic touch-ups, you can keep your smile bright indefinitely. Most patients enjoy their initial whitening results for 1-3 years before needing a full treatment again, with simple touch-ups extending results along the way. Investing in good habits—excellent oral hygiene, limiting staining foods, and regular professional cleanings—maximizes how long your bright smile lasts.
