‘In-chair’ tooth whitening is very efficient but often too efficient. Stronger tooth whitening chemicals are used and heat is applied (usually in the form of a light or laser) to speed up the chemical reactions. This method of tooth whitening often leads to extreme tooth sensitivity. While the sensitivity does usually settle after a few days, it can be extremely unpleasant.
“At Home” tooth whitening with trays puts the patient in control. If you find that even the at-home tooth whitening is starting to cause some sensitivity, you can reduce the length and/or frequency of wearing the tooth whitening trays. It might take a little longer to reach the desired degree of tooth whitening, but the desired result will be achieved.
