I have an underbite and/or a crossbite, can I use instasmile?
Yes, if you have an underbite and/or crossbite, you’ll still be able to use an instasmile. However, we recommend that your instasmile is for occasional use, and that eating with your instasmile in is kept to a minimum. This is because it may create unbalanced bite pressure that could damage your veneer. And don’t worry if you have an overbite, that’s very common and creates no issues with an instasmile.
