How Long Does Teeth Whitening Treatment Last?

Have you ever wondered how long does teeth whitening treatment results last? Regardless of the whitening product you use, the time the teeth stay white after whitening depends mainly on you and your lifestyle.

At Bangor Dental Care our teeth whitening treatment is administered by trained medical professionals. Teeth Whitening is a process where the tooth discolouration is ‘whitened’ to a lighter shade. It removes the staining agent through chemical means. It is a safe procedure when carried out under professional supervision. Treatment results usually depend on the severity of the discolouration.

Both vital (i.e. live) and non-vital teeth (e.g. tooth with root removed) can be bleached and may take several visits to complete. It is not effective on dental restorations such as amalgam fillings, metal or porcelain crowns, etc.

There are many factors that can affect the shade change of your teeth after whitening, so it’s important to have realistic expectations before and after the whitening treatment.

Depending on factors like current shade and staining, it may take longer to get that brighter, whiter smile. You should also know there are certain foods, habits (like smoking), and medications that can cause staining to occur after your teeth have been whitened.

You’ll want to avoid these as much as possible during whitening in order to maintain your white smile and those changes to habits and lifestyles will make your teeth whitening last considerably longer.
