Teeth Whitening Pro: It's Quick
Although it takes a little bit of time to prep for the procedure, including rinsing with a mouthwash, getting your gums sealed, and having your lips packed with gauze so you don't drool, the actual whitening only takes minutes. I did two sessions with the light at eight minutes each. There was a TV equipped with Netflix, so if you asked for the office to play your favourite comedy, the procedure would breeze by.
Teeth Whitening Con: It's Uncomfortable
You know how I mentioned you need to get your gums sealed and your lips packed with gauze? Yeah, that's not exactly pleasant. You have a contraption placed in your mouth that keeps your lips away from your teeth so they are able to perform the whitening properly. With your mouth pried open and your lips packed with gauze, it's easy to feel a little mouth-claustrophobic. Plus, you have to bite down on the mouthpiece that administers the light, so your mouth feels pretty packed for about 20 minutes.
