What is teeth whitening?
Whitening gels release oxygen that breaks down stain molecules inside the enamel. Supervised whitening is safer and more predictable than over-the-counter products because your dentist checks for cavities, gum problems and existing restorations first, protects your gums, and uses appropriate concentrations. Patients at OGHA have shared how professional whitening gave them the confidence to smile freely again.

Frequently asked questions
How long does teeth whitening last?
Results typically last from several months to a couple of years. They last longer if you limit tea, coffee, red wine and tobacco and maintain regular cleanings; occasional top-ups help.
Is teeth whitening safe?
Dentist-supervised whitening is considered safe for most adults. Temporary sensitivity is the most common side effect. A check-up beforehand ensures there is no decay or gum disease.
Will whitening work on crowns or veneers?
No. Whitening only lightens natural tooth enamel. Existing crowns, fillings or veneers may need replacement to match your new shade.
