If you know how to use them, they work very well. Heat them in boiling water for a few seconds, quickly shake off any drips that are stuck to them and insert the mouthguard into your mouth (use common sense if it seems too hot for you). that she is very hot, too hot. I think this works best if you create a vacuum effect in your mouth by pressing the back of the mouthguard against your teeth with your tongue and pressing your lips against the front of the mouthguard with your fingers. When the splints have cooled to around your mouth temperature, rinse the splints with cold water to harden them. Cut off any excess plastic where the tooth and gum meet to keep the whitening gel from getting on your gums! It's not a substitute for what a dentist can offer, but for the price these things work very well.
