If you drink coffee or tea every day, you may eventually notice that your teeth look darker than they used to. These drinks are common sources of tooth staining, but whether whitening can remove the discoloration depends on where the stain comes from.

Coffee and tea stains are common

Pigments from coffee and tea can build up on the teeth over time. Smoking can contribute to staining as well.

Some discoloration is on the surface of the teeth, while other colour changes are related to the internal structure of the tooth. That distinction matters because different types of discoloration respond differently to whitening.

Will professional whitening help?

For suitable natural teeth with staining that responds to bleaching, professional whitening can make the teeth visibly lighter. The amount of change varies between patients, so it is better for a dentist to assess the teeth than to promise a specific number of shades.

A dental cleaning may also be recommended if there is a significant amount of plaque or tartar. Cleaning and whitening are different treatments, but removing deposits can provide a cleaner starting point.

What about old fillings, crowns or veneers?

Whitening changes the colour of natural tooth structure. Existing restorations generally do not change colour in the same way.

If you have visible crowns, fillings or veneers, discuss them with your dentist before whitening so their colour can be taken into account when planning the final result.

Can whitening remove coffee stains?

Yes, when the stains are on natural tooth structure and respond to bleaching. Whitening will not change the colour of crowns, veneers or most fillings.

Do I need a cleaning before whitening?

Sometimes. If there is a lot of plaque or tartar, a cleaning can provide a cleaner starting point. However, cleaning and whitening are not the same treatment.
