There are 2 options when it comes to bleaching your teeth; in-chair or via the use of a take-home kit.
In-chair:
- Gum and oral tissues are isolated
- Bleach is directly applied to enamel
- In some cases a halogen or laser light can be used, but this is no longer common practice
- Usually takes around 1.5 hours (15 minute cycles which are repeated 3-4 times depending on the patient)
At home:
- Impressions of the teeth are taken and trays are made to fit your teeth
- Bleach is applied to the inside of the trays
- The length of time in which to wear the trays depends on the strength of the bleach being used
- The whitening can be done as frequently as required
