What whitening can and cannot do, how professional treatment differs from at-home kits, and how to look after your results.
Teeth naturally darken over time through food, drinks and everyday habits. Whitening lightens that surface staining, but it does not change the colour of crowns, veneers or fillings.
A dental check-up before whitening is a good idea. Your dentist can make sure your teeth and gums are healthy, explain the options, and suggest an approach that suits your sensitivity and goals.
To keep results looking fresh, brush twice a day, limit heavily staining drinks, and keep up with regular hygiene visits.
