Night guards help those suffering from chronic teeth-grinding during sleep, otherwise known as bruxism. Night guards issued by your dentist are often the highest quality you will find as well as the most superior fit as they are made in a special laboratory from an impression of your mouth carefully taken by one of our dental experts. This is normally a much more comfortable and reliable device than what you might find from an over-the-counter option. A night guard’s main function is to prevent the surfaces of your teeth from grinding together, causing you to chip and crack your teeth and strain your jaw muscles.
