In-office and take-home whitening for natural teeth, with shade checks and sensitivity care from Dr. Andy Keith in Hillcrest.
Teeth Whitening in San Diego, CA
In-Office & Take-Home
Same-Day Consults
Professional teeth whitening lightens natural enamel that has darkened from coffee, tea, red wine, tobacco, or age. At Sunrise Dental Arts there are two ways to do it, an in-office session for a faster change or custom take-home trays you wear on your own schedule, and both use a stronger gel than store kits under a dentist’s supervision.
Dr. Andy Keith starts by checking your teeth and gums and looking at what is causing the discoloration, because some stains respond well to bleaching and others do not. Whitening is often the first step in broader cosmetic dentistry, and he will tell you if bonding or veneers would serve you better.

How Professional Whitening Works
Whitening gels use hydrogen peroxide or carbamide peroxide to break stains into smaller pieces, which makes the color less concentrated and the tooth look lighter. The American Dental Association notes that yellow teeth usually bleach well, brown teeth may respond less, and teeth with gray tones may not lighten at all.
Whitening also has no effect on crowns, veneers, or fillings, and tooth-colored bonding keeps its shade too. It may not help discoloration caused by certain medications or an injury to the tooth. If any of those apply, we will talk about whether dental bonding or porcelain veneers are a better route.
What to Know Before You Whiten
Take-Home Trays
We take impressions of your teeth and make trays that fit closely over them. At home, you place a small amount of whitening gel in the trays and wear them for the time Dr. Keith recommends, usually daily over several days to a few weeks. This route is slower than an in-office session, but many people like whitening at their own pace, and the trays can be reused for touch-ups.
In-office whitening is done in one visit. We cover your gums and lips with a protective barrier, apply the gel to your teeth, and check your comfort and shade as it works. If dental visits make you anxious, sedation options such as nitrous oxide are available.
Your Whitening Visits, Step by Step
Shade Assessment and Goals
We record your starting shade, check for cavities, worn enamel, or gum problems that should be treated first, and ask how much lighter you want to go.
Treatment Selection
Based on your schedule and how sensitive your teeth are, you choose in-office whitening, take-home trays, or both. Some patients start in the office and use trays afterward for touch-ups.
Professional Whitening Session
For an in-office session, the gel is applied after your gums are protected and is checked as it works. For take-home whitening, we fit your trays and show you how much gel to use and how long to wear them.
Sensitivity Prevention
If your teeth feel sensitive, we can change how long or how often you whiten. Avoiding very hot or very cold food and drinks for a day or two, and brushing with a toothpaste made for sensitive teeth, often helps.
Maintenance Planning
Your shade will drift slowly as everyday foods and drinks restain enamel. Keep your trays for touch-ups, and we will check your color at regular cleanings and suggest a touch-up when it is needed.
Who Is a Good Candidate for Whitening
Whitening works best on natural teeth that have yellowed with age or from food and drink, in a mouth without untreated cavities or gum disease. We treat those first, because whitening gel on an open cavity or inflamed gums can be uncomfortable.
It is a weaker fit if your front teeth already have crowns, veneers, or large fillings, or if the discoloration is gray or came from medication or an injury. In those cases tooth-colored fillings, bonding, or a smile makeover plan may get you closer to the result you want.

FAQs
Is tooth whitening safe?
For most adults with healthy teeth and gums, yes. We check for cavities, gum problems, and existing restorations first, protect your gums during in-office treatment, and set how long you whiten. Temporary sensitivity is the most common side effect.
How long does tooth sensitivity last after teeth whitening?
When it happens, sensitivity is usually temporary and often fades within a few days of finishing treatment. If it lasts longer or feels sharp, call us so we can check the tooth.
Does tooth whitening damage enamel?
Whitening under a dentist’s supervision is generally considered safe for enamel when the gel is used as directed. Overusing whitening products, especially store kits, can increase sensitivity and irritate the gums, which is one reason we set how long and how often you whiten.
How can I reduce tooth sensitivity after whitening?
Take a break from whitening for a day or two, avoid very hot and very cold food and drinks, and brush with a toothpaste made for sensitive teeth. If you use trays, we can shorten your wear time or switch to a gentler gel.
How long does tooth whitening last?
Results usually fade gradually rather than all at once. How long they last depends on habits like coffee, tea, red wine, and tobacco. Occasional touch-ups with your take-home trays and regular cleanings help keep your shade longer.
Can I whiten if I have crowns or veneers?
Whitening lightens your natural teeth but not crowns, veneers, fillings, or bonding, so those may stand out afterward. If you plan new restorations, whiten first and match the new work to your lighter shade. If you already have restorations on your front teeth, we will talk about whether replacing them makes sense.
