Teeth whitening with veneers or crowns?


Do whiteners work on crowns or white fillings?

This is one of the questions often asked of  dentists and technicians. The answer is no, whitening products work only on natural tooth structure, but this is Ok – this does not rule you out as a candidate for having your teeth whitened – read on and find out why .

Old fillings might be whiter than the teeth.

If you had some work done, compare your treated tooth with a healthy one. The filling composite or porcelain will have almost the same colour it had the first day. Your teeth, however, probably got darker or have a yellowish tinge. The teeth’s natural colour changes gradually, therefore many people don’t even notice it unless they see an older photograph for example. In this case, if you choose a teeth whitening procedure, your teeth will be more uniform so there’s nothing to worry about. 

Do you have cavities?

Cavities should be taken care of as soon as possible. However, before you have a crown fitted in or a tooth filled, think whether you are going to whiten your teeth in the near future or not. If you are not happy with your colour, it would definitely be a good idea to have the whitening before the veneers or crowns. After this, the dentist can match the colours to your new pearly look. A two weeks pause between these two procedures is advisable. This will allow the enamel to remineralise and the final colour to stabilise. These two weeks are also important for the tooth’s hydration that will further on contribute to the filling’s bond strength.

Will the teeth whitening damage any previous dental restorations? 

Composite filling materials and porcelain are very resistant materials, therefore any past work is safe.
