If you have sensitive teeth already, you can still undergo a whitening procedure, but you will definately experience tooth sensitivity to some degree after the treatment.
Any sensitivity will subside in 1-2 days and return to normal. This is similar to what you would experience if you had your teeth cleaned at the hygienist.
If you do have sensitive teeth, just let me know and I will apply a de-sensitiser before treatment which will help with the sensitivity.
So not only will you leave Dazzle Studio with a bright new smile, you'll also be taking away a solution to your sensitive teeth!
