01 — Why professional whitening
Why choose professional teeth whitening?
Store-bought strips and kits use low-strength gel and one-size-fits-all trays, so results are slower and patchier, and gel can irritate your gums. Professional whitening uses stronger, dentist-supervised gel and trays made for your teeth, which means more noticeable, more even results — and someone to manage sensitivity if it happens.
At a glance
| Options | Take-home custom trays; ask about in-office whitening |
| Results | Can last a year or more, with touch-ups |
| Sensitivity | Usually mild and temporary; we adjust strength and wear time |
| Insurance | Usually not covered (cosmetic) |
Just as important, we check your teeth first. Whitening doesn’t change the color of fillings, crowns or veneers, and it can’t fix a tooth that is dark because of decay or an old injury. We’ll tell you what to expect before you spend a dollar.
Brighter smile, minus the guesswork
Book a checkup first — we’ll make sure your teeth are ready, set a realistic shade goal and fit your trays.
Whitening options
- Take-home whitening — custom-fit trays and professional gel you wear at home for a set time each day. Gradual, even and easy to touch up later.
- In-office whitening — a concentrated treatment in our chair for faster results, often followed by take-home trays to maintain them.
Is whitening safe?
When supervised by a dentist and used as directed, peroxide-based whitening is considered safe for most adults. The most common side effect is temporary tooth sensitivity, which usually fades within a few days. We can adjust the gel strength and wear time and recommend a desensitizing toothpaste. We generally recommend postponing whitening during pregnancy and nursing, and we treat cavities and gum problems first.
Keeping your smile bright
Results can last a year or more depending on your habits. Rinse after coffee, tea, red wine and dark sauces, don’t smoke, keep up your cleanings, and use your trays for an occasional touch-up.
Whitening before other cosmetic work
If you’re planning bonding, veneers or crowns on front teeth, whiten first. New restorations are matched to your whitened shade, so everything blends.
In-office vs. take-home whitening
| In-office | Take-home trays | |
|---|---|---|
| Speed | Fastest — noticeable change in one visit | Gradual, over one to two weeks |
| Control over sensitivity | Higher concentration in a short time | Lower strength, easy to pause or adjust |
| Touch-ups | Usually with take-home trays | Reuse your trays anytime |
| Best for | Events and quick results | Sensitive teeth and gradual change |
Whitening if you have sensitive teeth
Sensitive teeth can usually still be whitened with a gentler plan: lower-concentration gel, shorter wear times, breaks between sessions and a desensitizing toothpaste before and during treatment. We’ll first check for cavities or exposed roots that could make whitening uncomfortable.

05 — FAQ
Frequently asked questions
How white will my teeth get?
It depends on your natural shade and the type of stains. Yellowish stains usually respond well; grayish stains are more stubborn. We’ll give you a realistic goal at your visit.
Will whitening make my teeth sensitive?
Some people have temporary sensitivity. We can adjust the strength and schedule and suggest desensitizing products.
Does whitening work on crowns or fillings?
No. Whitening only changes natural tooth enamel. We may suggest replacing visible restorations after whitening so they match.
Does insurance cover whitening?
Usually not, because it’s cosmetic. Ask about financing if you’re combining whitening with other treatment.
Can I whiten if I have sensitive teeth?
Often, yes, with a gentler plan. We’ll check first for cavities or gum recession that could cause discomfort.
How much does teeth whitening cost?
It depends on whether you choose take-home trays, in-office whitening or both. We’ll quote it at your visit; financing is available if you’re combining whitening with other cosmetic work.
Is whitening safe during pregnancy?
We generally recommend postponing cosmetic whitening until after pregnancy and nursing.
