Frequently Asked Questions
1. What is teeth whitening and how does it work?
Teeth whitening is a cosmetic dental treatment that removes stains and discolouration from your teeth using safe whitening agents like hydrogen peroxide. These agents break down stains in the enamel to give you a brighter, whiter smile.
2. Is teeth whitening safe?
Yes, professional teeth whitening performed by a dentist is considered safe. Dentists use controlled products and techniques to minimise sensitivity and protect your gums and enamel.
3. How long does teeth whitening last?
Results from teeth whitening can last anywhere from several months to a few years, depending on your lifestyle, diet, and oral hygiene habits. Avoiding staining foods and drinks helps maintain results longer.
4. Does teeth whitening cause sensitivity?
Some patients may experience temporary sensitivity during or after teeth whitening. This is normal and usually subsides within a few days. Your dentist can recommend products to reduce discomfort.
5. How long does a teeth whitening treatment take?
In-chair teeth whitening treatments typically take around 60–90 minutes, while take-home kits may take a few days to a couple of weeks for full results.
6. Can all teeth be whitened?
Teeth whitening works best on natural teeth. It does not change the colour of crowns, veneers, or fillings, so your dentist may recommend alternative treatments if needed.
