The whitening gel contains peroxide and some other chemicals and so the dentists make sure that the gel does not fall on any tissues. The liquid dam material is hardened with the help of a blue UV light. After that, the whitening gel is applied to your teeth. This gel is too strong so remember that you should never touch the gel with your fingers during the treatment.

Then your mouth will be connected to a blue light machine for 15 minutes after properly protecting your eyes. Then the whitening gel will be sucked off of your teeth. Then the same happens in the second round. This may continue for another round based on the whiter shade you require.
