Before and After
Before and After Teeth Whitening Results
Professional whitening treatments can create dramatic improvements in smile brightness, often lightening teeth by 4–8 shades in a single treatment.
Patients frequently notice:
Brighter, whiter teeth immediately after treatment
Improved overall smile aesthetics
A more youthful appearance
Many patients come in with discoloration caused by coffee, tea, wine, aging, or smoking. Our professional whitening systems safely remove these stains while protecting the enamel and minimizing sensitivity.
Real patient transformations often show a noticeable improvement after just one session, with results continuing to brighten over the following days.

Frequently Asked Questions
Are at-home whitening kits effective?
For mild to moderate extrinsic staining, yes — particularly prescription-strength custom tray systems. Over-the-counter strips with 10% or higher hydrogen peroxide can produce visible improvement with consistent two-week use. However, at-home products cannot match the speed or depth of in-office whitening, and they are ineffective on intrinsic discoloration, existing restorations, or teeth with structural issues. They are best used as maintenance tools rather than primary treatments.
Can veneers make my teeth look unnaturally white?
Only if that is what the patient requests. Modern porcelain veneers are fabricated by skilled ceramists who can replicate virtually any shade — from natural off-white to vivid Hollywood white — with translucency and light reflection that mimics real enamel. At Lazare Biomimetic Dentistry & Smile Design, shade selection is a collaborative process that considers skin tone, eye color, age, and personal preference. The goal is always a result that looks intentionally beautiful, not artificially altered.
What foods and drinks should I avoid to keep my teeth white?
The most common contributors to tooth staining are coffee, black tea, red wine, dark sodas, tomato-based sauces, soy sauce, balsamic vinegar, blueberries, and blackberries. Tobacco — in any form — is among the most damaging. Rinsing with water immediately after consuming staining foods and beverages helps minimize contact time with enamel. Whitening toothpaste used regularly provides some ongoing maintenance benefit.
Is teeth whitening safe for sensitive teeth?
Yes, with appropriate protocols. Patients with existing sensitivity are evaluated before treatment, and modifications are made — including lower-concentration agents, shorter application times, and desensitizing pre-treatment. Post-whitening sensitivity is normal and typically resolves within 24 to 48 hours. Patients with significant sensitivity or exposed root surfaces may be better candidates for veneer-based whitening.
How long does professional teeth whitening last?
In-office whitening results typically last between one and three years, depending on diet, oral hygiene, and lifestyle factors. Patients who avoid heavy staining foods and tobacco, and who schedule periodic maintenance whitening, can extend results significantly. Custom take-home trays provided after in-office treatment help patients maintain their shade between professional visits.
