Why should I get a custom nightguard instead of one from the store?
Over-the-counter guards may work for some people, but they are not custom-fit to your teeth.
A professionally made nightguard is designed from your bite and fits more securely and comfortably. A better fit can make it easier to wear consistently and may provide better protection for your teeth.
Your dentist can also make sure the guard does not interfere with your bite.
