Q: How does whitening work?
A: Teeth whitening works intrinsically from the inside out, so there is no need for the entire tooth to be in contact with whitening agent in order for the entire tooth to be whitened. Peroxide gels break down into water, oxygen, and free radicals, which in turn oxidizes the bonds of coloured molecules that cause tooth discolouration.
Q: How long do whitening results last?
A: While whitening results are very stable long after the treatment is over, a few factors can affect the length of the whitening results such as genetics, diet, age, medication and certain habits. The procedure may need to be redone periodically.
Q: Will whitening cause tooth sensitivity?
A: Some people experience sensitivity while whitening, which is temporary. If desensitizing treatments are desired, we recommend the use of UltraEZ® desensitizing gel or Enamelast® fluoride varnish.
