Why whiten at the dentist
Professional products contain a stronger peroxide than store-bought ones, so they work faster and more precisely. We also protect your gums during treatment, which helps prevent irritation. Over-the-counter kits use the same tray for everyone, so they can leak onto the gums, and some contain ingredients that do more harm than good. Results from professional whitening usually last longer than those from store products, especially with good oral hygiene.
Whitening and bleaching are close cousins. Dentists generally use whitening for removing surface stains and bleaching for lightening the enamel itself. Both use peroxide, which penetrates the enamel and makes teeth reflect more light.
Your options
- In-office whitening. We apply the whitening agent to your teeth, often with a special light, heat or laser. It is the fastest route. Teeth can get about three to eight shades lighter over several 30 to 60 minute sessions, and some systems finish in a single two-hour visit. Studies on laser results vary, so ask us if it is right for you.
- Custom take-home trays. We make trays that fit your teeth and you wear them with whitening gel at home, usually for a few hours a day or overnight for a few weeks. They leak less than store-bought trays.
- A combination. Many patients start in the office and finish at home. Our Zoom whitening works this way.
What to expect
- Consultation. We review your dental history and health, and look for cavities or gum problems to treat first. Crowns, veneers and fillings do not respond to whitening agents, and we will explain how that affects your results.
- Cleaning. We polish your teeth to remove plaque and tartar, which helps the color come out even.
- Protection. We shield your lips, cheeks, tongue and gums from the whitening agent.
- Whitening. We apply the agent, activate it if the system calls for it, and rinse when your teeth reach the shade you want.
- Aftercare. We may fit you for trays and show you how to keep your results.
Who is a good candidate
Whitening works best on yellow teeth and can help some brown ones. Gray or purple tones usually come from trauma or decay, and bleaching may not change them. We do not recommend whitening if you have gum disease, worn enamel or untreated cavities, if you are allergic to peroxide, or if you are pregnant or nursing. If whitening is not right for you, options such as veneers may be.
Keeping your results
Whitening is not permanent. Avoid smoking and limit coffee, tea and red wine. Rinse with water or brush after them, or use a straw. Brush twice a day, floss daily and keep your cleanings and exams. We can talk about touch-ups, often at six-month intervals.

Common questions
Is teeth whitening safe?
It is considered safe when supervised by a dentist. Some people notice temporary tooth sensitivity or gum irritation, which usually fades once treatment ends.
Can I whiten if I have crowns, implants or a bridge?
Yes, but whitening only changes natural teeth. We can talk about keeping the color even across all your teeth.
How long do the results last?
It varies with the product, your habits and your teeth. Professional whitening usually lasts longer than store products, but it fades over time and can be refreshed with touch-ups.
Can whitening remove stains from smoking?
Often, yes. Results differ from person to person. If some teeth do not respond, veneers or other options may help.
Does insurance cover whitening?
Most dental plans do not cover whitening or other cosmetic procedures, but every plan is different. Check with your insurer.
