Professional teeth whitening at 101 Dental & Orthodontics uses clinically formulated bleaching agents at concentrations that are not available in over-the-counter products, delivering results that are both faster and more even than home kits. Dr. Chang assesses each patient's suitability before treatment — checking for active decay, gum disease, or existing restorations that could affect the outcome — ensuring whitening is safe and appropriate for your specific dentition. Take-home tray whitening, using custom-fitted trays made from impressions of your teeth, allows you to whiten at your own pace while maintaining clinical-grade results.

Bleaching agents do not alter the colour of porcelain or composite restorations — only natural tooth enamel responds to whitening treatment. Dr. Chang will assess the shade of your existing restorations before treatment and advise on whether whitening your natural teeth will create a noticeable mismatch that might require updating those restorations.
Results typically last 1–3 years depending on dietary habits — regular consumption of coffee, tea, red wine, and tobacco accelerates restaining. Touch-up treatments using your original custom trays can extend results significantly, and Dr. Chang will advise on a maintenance schedule suited to your lifestyle.
Sensitivity is the most common side effect of whitening and is usually temporary, resolving within 24–48 hours of each treatment session. Dr. Chang screens for pre-existing sensitivity and exposed dentine before recommending whitening, and can adjust the bleaching concentration or treatment duration to reduce the likelihood of discomfort.
