Most people prefer the upper night guard because it feels less in the way of the tongue, making it both more comfortable and easier to speak with. If this is your first time wearing a custom made night guard, we recommend going with the upper.
Should I wear my night guard on the top or bottom?
Wearing a lower nightguard is considered the standard by most dentists. A lower nightguard is usually more comfortable to wear. It is also less likely to fall out of your mouth due to gravitational forces. Plus, wearing a lower night guard directly protects your TMJ and lower jaw.
Which way does a mouthguard go?
Place the mouthguard in the ice water. It should fit snugly against your top teeth without having to hold it with your tongue, and it should fit naturally into your bottom teeth.
