Teeth Whitening FAQ

Teeth whitening results can last from a few months to a few years, depending on your oral hygiene habits and lifestyle choices.

Yes, when performed by a dental professional or according to provided instructions, teeth whitening is generally safe. However, overuse or incorrect use can lead to sensitivity and enamel damage.

Overuse or improper application of whitening products can cause enamel damage and gum irritation. It’s important to follow professional guidance.

Teeth whitening is most effective on extrinsic stains (surface stains). Intrinsic stains (within the tooth) may not respond well to whitening treatments.

Using toothpaste designed for sensitive teeth, avoiding very hot or cold foods and drinks, and using a soft-bristled toothbrush can help alleviate sensitivity.

Over-the-counter products can be effective for mild staining but may not be as potent as professional treatments. Results vary depending on the product and usage.

It’s recommended to wait at least six months to a year between whitening treatments to prevent damage to your teeth and gums.

Whitening treatments do not affect fillings, crowns, or other dental restorations. Consult your dentist for options that match your natural tooth colour with your restorations.

 Avoid foods and drinks that can stain your teeth, such as coffee, tea, red wine, and tobacco, especially in the first 48 hours after treatment.

Not everyone is a candidate for teeth whitening. Individuals with dental issues, pregnant or nursing women, and those allergic to peroxide should seek alternatives.
