Professional whitening uses prescription-strength agents that deliver results store-bought strips simply cannot match. In-office treatment takes about 60–90 minutes and can lighten teeth up to 8–10 shades in a single session. We also offer custom take-home trays for patients who prefer to whiten on their own schedule. Cost: $300–$500 for in-office; $200–$400 for take-home trays.
How much whiter can professional teeth whitening make your teeth?
Professional teeth whitening delivers results that over-the-counter products cannot match, using higher-concentration whitening agents applied under controlled conditions for maximum effectiveness and safety. At Spring Valley Dental, we offer two options: in-office whitening for immediate results in about 90 minutes, and custom take-home trays for gradual whitening on your schedule.
What to expect
Initial assessment
We check for cavities and gum issues that should be treated before whitening, and assess your baseline shade.

Frequently asked questions
Most patients see a shade improvement of 4–8 shades with professional whitening. The final result depends on the baseline color of your teeth, the type of staining, and the thickness of your enamel. We set realistic expectations at your appointment and recommend the approach most likely to get you the result you want.
Some temporary sensitivity is normal during and after whitening, particularly to cold temperatures. It typically resolves within 24–48 hours. We provide recommendations to minimize sensitivity, including using a desensitizing toothpaste before treatment.
With touch-up maintenance, professional whitening results can last 1–3 years. Regular coffee, tea, and red wine consumption will shorten the duration. We provide custom take-home trays for periodic maintenance.
Whitening gel only works on natural tooth enamel, it won't change the color of crowns, veneers, or bonding. If you have visible restorations that you want to match to whitened teeth, we can discuss replacement options. We'll review this with you before recommending whitening.
For very mild staining, OTC strips can provide modest results. For most patients who want meaningful improvement, professional whitening is significantly more effective and worth the investment. We'll give you an honest recommendation at your consultation.
