The Ultimate Guide to Dental Code for a Bite Plate: Coverage, Uses, and Billing

A bite plate (or occlusal guard) is a dental appliance designed to protect teeth from grinding (bruxism), correct bite alignment, or assist in TMJ disorder treatment. Dentists use specific Current Dental Terminology (CDT) codes to bill for bite plates, ensuring proper insurance claims and reimbursement.

This comprehensive guide explores everything about dental codes for bite plates, including types, uses, insurance coverage, and billing best practices. Whether you’re a patient seeking clarity or a dental professional refining billing processes, this article provides in-depth insights.

2. What Is a Bite Plate?

A bite plate is a removable or fixed oral device made from acrylic or other durable materials. It fits over the upper or lower teeth to:

• Prevent teeth grinding (bruxism)

• Reduce jaw pain from TMJ disorders

• Correct misaligned bites (malocclusion)

• Protect teeth during sports

Bite plates are custom-made by dental labs based on a dentist’s prescription.

3. Types of Bite Plates

4. Common Uses of Bite Plates in Dentistry

A. Treating Bruxism (Teeth Grinding)

• Prevents enamel wear and fractures.

• Reduces muscle strain in the jaw.

B. TMJ Disorder Relief

• Alleviates pain from temporomandibular joint dysfunction.

• Helps reposition the jaw for better alignment.

C. Orthodontic Applications

• Corrects deep bites or crossbites.

• Assists in post-braces retention.

D. Sports Protection

• Custom-fitted guards prevent dental injuries in athletes.

5. Dental Codes for Bite Plates (CDT Codes)

The American Dental Association (ADA) assigns CDT codes for bite plates:

• D9944 – Occlusal Guard (Hard, Custom-Fabricated)

  • Used for night guards and TMJ appliances.

• D7880 – Occlusal Orthotic Device

  • For TMJ-related bite correction.

• D8210 – Bite Plane (Acrylic)

  • Used in orthodontic treatments.

Note: Insurance companies may require pre-authorization for certain codes.

6. Insurance Coverage and Reimbursement

• Medical vs. Dental Insurance:

  • Dental insurance may cover bite plates under “preventive” or “restorative” benefits.

  • Medical insurance may cover them if linked to TMJ disorder.

• Typical Coverage:

  • 50%-80% of the cost, depending on the plan.

  • Some insurers limit coverage to one guard every 3-5 years.

Pro Tip: Submit a Letter of Medical Necessity (LMN) if insurance denies the claim.

7. How Dentists Determine the Need for a Bite Plate

Dentists assess:

• Signs of tooth wear from grinding.

• Jaw pain or clicking (TMJ symptoms).

• Bite misalignment issues.

• Sleep study results (for severe bruxism cases).

8. The Process of Getting a Custom Bite Plate

1. Examination & Diagnosis – Dentist evaluates bite and jaw function.

2. Impressions or Digital Scan – For a precise fit.
