Teeth Whitening

Teeth whitening is the process of colouring or lightening the shade of your teeth without removing any of actual tooth itself. This is typically done with a whitening gel which is applied during the whitening treatment. The results we achieve for patients with teeth whitening in Hamilton, NZ - speak for themselves.  We’ve had many satisfied customers from our teeth whitening services who leave brimming with happy white smiles as a result.

Are all teeth suitable for whitening?

Whitening may be done on live teeth and teeth that have had root canal treatment. Before having your teeth whitened, our dentists will check to make sure your teeth are suitable to be treated. Tooth whitening may make your old fillings or crowns look darker after treatment, so it is very important to be checked and advised of this before you proceed.

How do we whiten your teeth?

Tooth whitening can be done at home (using a customised mouth tray system designed by your dentist) or at the clinic. We can provide a more effective tooth whitening system for use at home than the ‘do-it-yourself’ teeth whitening kits and whitening strips available at pharmacies.

First, our dentists make an impression for a model of your teeth. A thin, custom-fitted, clear plastic tray that fits over your teeth is then made. At home, you place a whitening gel into the tray and place the tray over your teeth. This is worn for up to two hours daily or at night.
Results are usually seen after the first day, but maximum whitening may take 10-14 days. We will monitor your progress to ensure the best possible results.

For a more immediate and longer-lasting effect for a brighter smile, we can also whiten your teeth here at the Hamilton Dental Centre. While in the dental chair the whitening gel is applied to the tooth and activated with a special led light for up to 15 minutes. Several repeat processes may be necessary.

Are there any side effects?

Sometimes people will experience increased tooth and gum sensitivity during treatment, which goes away shortly after stopping the treatment. We recommend starting fluoride gel treatment two weeks before (available at the Centre) and taking a panadol an hour before to decrease sensitivity.

Can teeth with root fillings be whitened?

Yes, root-filled teeth are treated by placing bleach inside the tooth. A protective rubber shield is placed over the tooth, and the tooth is partly opened into where the root filling has been placed. The inside is cleaned and a bleaching material is placed inside. The tooth is temporarily resealed and left 7 – 10 days. Sometimes two or three applications may be necessary.

How long does tooth whitening last?

Over time your teeth can lose some of their whiteness. Foods with strong colouring like coffee and red wine will stain teeth faster. You may need to repeat the whitening process occasionally. After a professional in-chair whitening procedure, a take-home top up kit is usually fine to maintain whiter teeth and that bright smile.
