ey everyone. I was hesitant to purchase these strips because of all these horror stories about gum irritation, but quite simply, those of you who had gum irritation are not using the product correctly. Here are some ways to ensure you don't get gum pain:
1) when you soak the mouthpiece, be sure the water is hot enough to allow the mouthpiece to form well to your teeth
2) when forming the mouthpiece to your teeth, adjust it in such a way that the top part of the plastic is not very far up on the gum line
3) to prevent contact of the gel to the gums, use toilet paper! this sounds odd, but apply some toilet paper to the gums, covering as much as possible without covering the teeth. this also helps by drying up the gums so there's less saliva and the mouthpiece stays put better.
4) when you apply the gel, be sure there's none that's leaked out on the bottom of the mouthpiece that could burn the roof of the mouth or tongue
5) don't use the entire tube of gel for a session! doing so increases the likelihood that the gel will seep out and contact the gums.
6) we all want this whitening to be easy, but if you're serious about getting whiter teeth, sit still and close your mouth for the entire whitening time. moving around/constantly readjusting only makes things worse.
7) if you're worried still about causing irritation, don't do them all at once. space them out over the course of several days. after all, they aren't very expensive so worse case scenario you just buy more!
i hope this helps!
