Teeth Whitening
Professional whitening in one office visit or with custom take-home trays, supervised by a doctor, at our Fremont, Cupertino, and Milpitas offices.
Professional teeth whitening in the Bay Area
Whitening is the simplest cosmetic treatment there is. Nothing is drilled or bonded, results are visible right away, and the effect can last a year or more with reasonable habits. Done in a dental office, it is also far more predictable than the strips and gels at the pharmacy, because the gel is stronger, the fit is exact, and a doctor checks your teeth and gums first.
Both of our options use the same peroxide-based gels that dentists have used safely for decades, at strengths that are only available through a dental office. The American Dental Association covers the basics of how whitening works and what to expect.
In-office or take-home trays
In-office whitening is the fast route. Your gums are protected, a high-strength gel is applied and refreshed over about an hour, and you leave noticeably brighter in a single visit. It suits a deadline: a wedding, photos, an interview. Some patients feel cold sensitivity for a day or two afterward.
Take-home trays are made from a scan or impression of your teeth, so the gel sits exactly where it should and nowhere else. You wear them for a short stretch each day over two to three weeks and stop when you like the shade. The trays last for years, so a touch-up later is just a fresh syringe of gel. This is the gentler, more controllable option and the better value over time.
For stubborn or deep staining we often combine the two: in-office first for the big shift, then trays at home to refine and hold it. Your doctor will tell you which fits your teeth and your timeline.
Whiten before crowns, veneers, or bonding
Whitening only works on natural enamel. Crowns, veneers, bridges, and composite bonding stay exactly the shade they were made in. If a restoration is placed first and you whiten afterward, your own teeth get lighter and the restoration does not, and the only fix is to remake it.
So the order is always whiten first, then match any new work to the new shade. If you are considering crowns, veneers, or bonding, tell us at your consultation and we will sequence it correctly.
What whitening cannot change
Surface stains from coffee, tea, wine, and tobacco respond well. Discoloration that comes from inside the tooth is harder: the natural yellowing of age, tetracycline taken in childhood, a tooth that darkened after an injury. Some of these lighten with longer treatment; some are better handled with bonding or veneers. We will tell you plainly which you have before you spend anything.
Existing fillings, crowns, and veneers will not lighten. If they are on front teeth, we discuss whether replacing them after whitening makes sense. A routine cleaning first is a good idea too: clean enamel takes the gel more evenly, and some surface stain comes off with the cleaning alone.
Keeping the result
The first two days matter most. Enamel is slightly more porous right after whitening, so stick to pale foods and skip coffee, tea, red wine, dark sodas, berries, and curry for 48 hours. Tobacco undoes whitening faster than anything else. After that, normal life resumes.
Long term, a straw for staining drinks, a rinse with water when you cannot brush, and an occasional touch-up with your trays keep things bright. If sensitivity shows up, an anti-sensitivity toothpaste for a couple of weeks before and after treatment makes a real difference.
Teeth whitening, answered
How much does professional whitening cost?
It depends on whether you choose in-office treatment, take-home trays, or both. Whitening is cosmetic, so dental plans generally do not cover it. We give you exact pricing at your consultation before anything starts.
Is whitening safe?
Yes, with a dentist supervising. The peroxide gels we use have a long safety record, and the ADA recommends talking to your dentist first, which is exactly what a consultation is for. The most common side effect is temporary sensitivity, which fades within a few days.
Does it hurt?
The treatment itself does not. Some patients notice cold sensitivity for a day or two afterward, which settles on its own. Using an anti-sensitivity toothpaste for a couple of weeks before and after reduces it noticeably.
Should I whiten before getting a crown or veneers?
Always. Crowns, veneers, and bonding are made to a fixed shade and do not lighten with bleaching. Whiten first, then we match the new work to your brighter teeth.
How long does it last?
Often a year or more, and longer if you go easy on coffee, tea, red wine, and tobacco. Take-home trays make maintenance simple: a few nights of gel brings the shade back.
Are drugstore strips as good?
They can help with light surface stain, but the gel is weaker and the strip does not fit your teeth, so results are often patchy and miss the edges. Patients who have used strips for years are usually surprised by the difference custom trays make.
Can I whiten while pregnant or breastfeeding?
We recommend waiting. There is no evidence of harm, but safety has not been specifically studied either, and cosmetic treatment can easily wait a few months.
