Teeth whitening uses peroxide-based gels to lighten the natural colour of teeth. When supervised by a dentist, the concentration, application and duration are controlled to balance results and comfort.
Whitening only changes natural tooth structure. Existing crowns, veneers and fillings do not lighten, which is why an assessment before whitening is important for anyone with visible dental work.

How teeth whitening works
In-clinic whitening applies a higher-strength gel with the gums protected. Home whitening uses custom-made trays and a lower-concentration gel worn for a set period each day. Many patients use a combination.
Some stains, such as those from tetracycline or fluorosis, respond less predictably and may need other approaches.
Consultation and assessment
Dr. Paul will check for decay, gum problems, cracks and existing restorations, record your starting shade, and explain what change is realistic for your teeth. Whitening is not recommended during pregnancy or for anyone under 18 in many jurisdictions.
