Bacterial plaque on your teeth become stained by all the colourful foods that you consume. The extrinsic stain is a buildup of coloured plaque on your teeth and professional teeth whitening treatments primarily remove that surface stain from all of your front teeth.
The hydrogen peroxide liquid and gel used for teeth whitening treatments can also pass through your tooth enamel to permanently whiten your underlying dentin.
First, a protective liquid gum barrier is placed over your gums and it is set hard with a white light. Then the teeth whitening liquid and gel are spread over your tooth enamel with a cotton tip. A white light shines on your teeth for a few minutes to gently activate the teeth whitening liquid and gel.
Once the gum barrier and teeth whitening gel are removed, your teeth will look much whiter and you will have a glowing whiter smile.
