- Professional teeth whitening uses dentist-strength gels that can lift surface and deeper stains more effectively than most store-bought strips.
- At Vaksman Dental Group in South San Francisco, our dentists offer both in-office and custom take-home whitening so you can choose what fits your schedule.
- Whitening works best on natural tooth enamel; it typically does not change the color of fillings, crowns, veneers, or bridges.
- Mild, temporary tooth sensitivity is the most common side effect and usually fades within a day or two.
- A quick exam first helps confirm whitening is right for you and that your teeth and gums are healthy.
If your smile has dulled from coffee, tea, wine, or simply the years, professional teeth whitening can lift away stains more effectively and safely than store-bought strips. At Vaksman Dental Group in South San Francisco, our dentists offer both in-office and take-home whitening tailored to your teeth, so you can brighten your smile in a way that fits your comfort, timeline, and budget.
What Is Professional Teeth Whitening?
Teeth whitening is a cosmetic treatment that uses a peroxide-based gel to break down stains that build up on and within your enamel over time. Professional whitening uses stronger, carefully controlled gels than the ones you’ll find at the drugstore, and your treatment is supervised by a dental professional. According to the American Dental Association’s consumer site, whitening products work by using hydrogen peroxide or carbamide peroxide to lighten the shade of your teeth (MouthHealthy.org).
There are two main ways we whiten at our office:
- In-office whitening: A higher-strength gel is applied in the chair while your gums are protected, often producing a visible change in a single visit.
- Custom take-home trays: We make trays molded to your teeth and provide professional gel so you can whiten gradually at home over a week or two.
Who Can Benefit From Whitening?
Whitening is a good option for many adults in South San Francisco, San Bruno, Daly City, and the surrounding Peninsula who want to refresh a smile that has yellowed or dulled. It tends to work best for stains caused by everyday habits and aging, such as:
- Coffee, tea, red wine, and dark sodas
- Tobacco use
- Deeply colored foods like berries and tomato-based sauces
- Natural yellowing that often comes with age
Whitening is not right for everyone. Stains from certain medications, trauma, or developmental causes may respond less predictably, and whitening gels do not change the color of dental work such as crowns, veneers, or fillings. If you have untreated cavities or gum issues, those are typically addressed first. That’s why we start with a quick look at your teeth — and if whitening isn’t the best fit, options like porcelain veneers may be discussed.
What to Expect During Treatment
Your whitening journey usually begins with a brief exam and cleaning so we’re working with a healthy, plaque-free surface. Many patients pair whitening with a routine professional cleaning to remove surface buildup first.
For in-office whitening, we protect your gums and lips, apply the professional gel, and let it work for short, timed intervals. The whole visit often takes about an hour. For take-home trays, we’ll show you how to fill the trays with the right amount of gel and how long to wear them each day. Either way, our dental team walks you through every step so you know what’s happening and feel comfortable.
Benefits of Professional Whitening
- Stronger, controlled results: Dentist-supervised gels can address stains that over-the-counter products may not reach.
- Custom fit: Trays molded to your teeth help keep gel on the enamel and off the gums, which can reduce irritation.
- A professional eye: We check that your teeth and gums are healthy first, so you’re whitening safely.
- Flexibility: Choose a faster in-office result or a gradual at-home approach.
What Does Teeth Whitening Cost?
Costs vary by the method you choose and the condition of your teeth. As a general national reference — these are general figures, not our office’s prices — in-office professional whitening often ranges from about $300 to $800, while custom take-home trays from a dental office commonly run about $150 to $400. Over-the-counter strips are cheaper but typically use weaker gels and don’t include a custom fit or professional oversight. We’re happy to review your specific options and any pricing during your visit.
Aftercare and Keeping Your Smile Bright
Results can last from several months to a few years depending on your habits. To help your whitening last:
- For a day or two after treatment, limit deeply colored foods and drinks while your enamel rehydrates.
- Use a straw for coffee, tea, and other staining beverages when you can.
- Brush twice a day and floss daily, and consider rinsing after staining drinks.
- Keep up with regular checkups — staying on top of your routine dental exams helps us catch issues early and keep your smile healthy.
Mild tooth sensitivity is the most common side effect and usually fades within a day or two. If you ever have lingering discomfort, let us know and we can adjust your plan.
Frequently Asked Questions
Is professional teeth whitening safe?
When done under the care of a dental professional, whitening is generally considered safe for most healthy adults. The American Dental Association notes that peroxide-based whitening products can be used safely when directions are followed (ADA.org). We check that your teeth and gums are healthy first and protect your gums during in-office treatment to help keep you comfortable.
How long do whitening results last?
Results often last anywhere from several months to a couple of years. How long your smile stays bright depends largely on your habits — coffee, tea, red wine, and tobacco can bring stains back sooner. Good home care and occasional touch-ups can help extend your results.
Will whitening cause sensitivity?
Some people notice mild, temporary tooth or gum sensitivity during or after whitening. It typically fades within a day or two. If you’re prone to sensitivity, let our dentists know — we can recommend a gentler approach or a desensitizing product.
Can I just use whitening strips from the store instead?
Over-the-counter strips can help with mild surface stains, but they use weaker gels and don’t include a custom-fit tray or a professional exam. Professional whitening offers stronger, more controlled results and the reassurance that your teeth and gums are healthy enough to whiten safely.
