Opalescence 20% 4pk

Product Review (submitted on April 11, 2019):

Dentamart has been great to purchase from. This is the same whitener that my dentist uses. I have used 20% and 35% strengths and I prefer 20%. 35% has to be used carefully as it can sting the gums. 20% works well and takes away all of the coffee and other stains.
