Is professional teeth whitening safe?

Yes. We evaluate your teeth and gums first, then use dentist‑supervised whitening gel and controlled light or take‑home trays to brighten safely without harming enamel.

How long do whitening results last?

Most patients enjoy results for 12–24 months. The exact timeline depends on coffee/tea, red wine, tobacco, and how consistently you follow home care.

Will whitening make my teeth sensitive?

Mild sensitivity is common for a day or two. We tailor the strength and timing to your comfort and can recommend desensitizing toothpaste or in‑office fluoride.

What’s the difference between ZOOM whitening and store‑bought kits?

In‑office whitening uses higher‑quality gel and professional isolation, so you see a bigger change faster and with less risk of irritation. Store kits can help, but they’re less predictable.

Can crowns or veneers be whitened?

No. Whitening only changes natural enamel. If you have visible restorations, we’ll plan whitening first and then match new restorations to your brighter shade if needed.

Teeth Whitening in Palo Alto

If your smile feels a little dull from coffee, tea, red wine, or natural aging, professional teeth whitening is one of the fastest ways to look refreshed. We offer dentist‑supervised whitening tailored to your goals and sensitivity level—so you get a brighter smile without guessing.

We start with a quick evaluation to confirm whitening is a good fit. If there’s decay, worn enamel, or gum inflammation, we’ll address that first so whitening feels comfortable and lasts longer.

Whitening options we offer

Our most popular option is professional in‑office whitening using ZOOM! whitening in Palo Alto. In a single visit, we isolate the gums, apply professional whitening gel, and use controlled activation to brighten efficiently. If you’d prefer a more gradual approach, we also offer custom take‑home trays with professional gel and clear instructions.

Not sure which to choose? Many Palo Alto patients do a “boost + maintain” plan: an in‑office session for a quick jump in brightness, then take‑home trays a few times a year to maintain results. We’ll help you pick a plan that matches your timeline and comfort level.

In‑office whitening (fast results)

Ideal if you want a noticeable change quickly. We isolate soft tissue, confirm your shade goal, and tailor strength and timing to reduce irritation and sensitivity.

Custom take‑home trays (gradual)

Great for a slower change, touch‑ups, or patients prone to sensitivity. Trays fit precisely, so gel stays where it belongs and results feel more predictable.

Is whitening right for you?

Whitening works best when teeth and gums are healthy. We’ll confirm candidacy first and then recommend the safest plan to reach a natural shade goal.

Often a good fit for

Coffee, tea, red wine, or aging-related surface stains

A refresh before a big event or photos

Patients who want safer, more predictable results than store kits

We’ll plan around

Visible crowns, veneers, or bonding on front teeth (these don’t whiten)

Very deep internal discoloration where veneers may be a better match

Active decay or gum inflammation (we’ll treat this first)

What whitening can and can’t change

Whitening brightens natural enamel. If you have visible restorations (like veneers, crowns, or bonding) we plan the sequence so your final shade looks even.

Whitening can help with

Yellowing from coffee/tea, wine, or aging

A brighter shade across natural enamel

Improving your smile before Invisalign or cosmetic finishing

Whitening can’t change

The color of crowns, veneers, or tooth‑colored fillings

Severe internal stains in every situation (we’ll discuss alternatives)

Uneven brightness if existing restorations are visible (planning helps)

If you have front‑tooth restorations and want a brighter look, we can discuss whitening first and then matching new restorations to the brighter shade.

What to expect at your whitening visit

Your appointment starts with shade photos so we can measure improvement. We protect lips and gums, then apply whitening gel in controlled sessions. If you’re prone to sensitivity, we can adjust concentration or timing and add desensitizing steps. After we reach your target shade, we review home care and foods to avoid for the first 24–48 hours.

Sensitivity: what we do to minimize it

Some sensitivity is common after whitening, but comfort matters. We tailor your plan and share practical post‑care so you can keep results without feeling “zingy.”

Start with an exam so whitening is safe for enamel and gums

Tailor gel strength and timing based on your sensitivity history

Use desensitizing steps and fluoride when helpful

Share a 24–48 hour post-care plan to reduce sensitivity triggers

Keeping your results bright

Whitening lasts longest when your teeth are healthy and clean. Regular visits for dental cleanings in Palo Alto help remove surface stains and keep your shade stable. At home, brush twice daily, floss, and consider using a whitening toothpaste a few times per week. If you drink staining beverages, rinsing with water afterward can make a big difference.

Want a simple maintenance plan? Ask about take‑home trays so you can do occasional touch‑ups without starting from scratch.

Cost factors and planning

Whitening is personalized, so cost depends on your plan and goals. After your evaluation, we’ll explain options and provide a clear estimate before you start.

Whether you choose in‑office whitening, take‑home trays, or both

Sensitivity considerations that affect strength and timing

Whether you have restorations that may need to be color-matched afterward
