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 an unbalanced bite pressure that could damage your clip-on veneer. And don't worry if you have an overbite, that's very common and creates no issues with an instasmile. If you have a severe overbite and or your teeth stick out or protrude, please understand that the instasmile will exaggerate this as we are adding 0.6mm-1.0mm to your natural teeth.
