Is there any bad effects of having laser bleach for my tooth?

Possibly: Bleaching of teeth is generally a very safe procedure however in rare situations adverse effects can occur. A specific example of this is invasive cervical resorption. It is suspected that this reaction occurs due to a gap found in 10% of patients between the enamel and dentin called gap junctions. This area may be adversely effected by the bleaching and cause a hole to develop.

No: Laser bleaching is safe.
