Effect : It can last anywhere between 2-6 months. It depends on the color of your teeth, how much you smoke and if you drink red wine or not.
Dr. Yigal Prilutsky
Dentistry 20 years experience
It varies: The results of any whitening method last from a couple of months to about a year. It depends on several factors- foods you eat, drinks you drink, smoking, chewing tobacco, porosity of your enamel, and types of stains you are more susceptible to.
Dr. Arman Dayan
Cosmetic Dentistry 33 years experience
Varies: The best way to make the result of the treatment last is to use a touch up kit following the laser.

Dr. Shawn Murray

Mouth guards: Almost every dentist can make you a custom mouth guard. You shouldn't buy a mouth guard that is not made for you specifically or it can cause problems. Just like one size fits all shoes aren't a good idea.
