Do you wake up with jaw pain, headaches, or sensitive teeth? You might be grinding your teeth at night—a condition known as bruxism. Millions of people suffer from this issue, often without realizing it. Fortunately, night guards (also called occlusal guards) can protect your teeth and improve your sleep quality.
But how do dentists bill for night guards? What is the ADA dental code for a night guard? And what types are available? This comprehensive guide answers all these questions and more, helping you understand the importance of night guards, the ADA coding system, and how to get the best treatment.

2. What Is a Night Guard?
A night guard is a dental appliance worn while sleeping to protect teeth from grinding (bruxism) or clenching. It acts as a cushion, absorbing pressure and preventing damage to teeth, gums, and jaw joints.
Night guards can be:
-
Custom-made (by a dentist for a perfect fit)
-
Boil-and-bite (semi-customizable at home)
-
Over-the-counter (OTC) (pre-formed, least effective)
The American Dental Association (ADA) classifies night guards under specific billing codes, which we’ll explore in detail.
3. Why Are Night Guards Important?
Without a night guard, chronic teeth grinding can lead to:
-
Tooth fractures and worn enamel
-
Jaw pain and TMJ disorders
-
Chronic headaches and migraines
-
Gum recession and tooth sensitivity
A well-fitted night guard prevents these issues, improving oral health and sleep quality.
