This product can only be used with custom fitted whitening trays.
No matter what brand of tooth whitening gel you use, tooth sensitivity is a common side effect. The UltraEZ® desensitizing gel is worn AFTER you bleach your teeth and we recommend to wear it overnight. This will make the whitening process more comfortable.
This is an excellent whitening gel. You feel a little discomfort the first time but you get used to it and the results are amazing!
