Teeth grinding (bruxism) and jaw clenching affect millions of people worldwide, often leading to severe dental damage, headaches, and temporomandibular joint (TMJ) disorders.

This comprehensive guide explores every aspect of the D7840 dental code, including its clinical applications, fabrication process, insurance considerations, and long-term care. Whether you’re a patient seeking relief or a dental professional looking for detailed insights, this article provides an in-depth analysis of occlusal guard therapy.

2. Understanding the D7840 Dental Code

Definition and Purpose

The D7840 code is used by dental professionals to bill for an occlusal guard, also known as a night guard or bite splint. This device is fabricated to fit a patient’s upper or lower dental arch, providing a protective barrier that prevents tooth damage caused by grinding (bruxism) or clenching.

When Is It Used?

• Nocturnal Bruxism: Nighttime teeth grinding.

• Daytime Clenching: Stress-related jaw tension.

• TMJ Disorders: To alleviate jaw pain and misalignment.

• Dental Protection: Post-restorative work (crowns, veneers, implants).

3. Types of Occlusal Guards

Custom vs. Over-the-Counter (OTC) Guards

• Custom Guards (D7840): Made from dental impressions, offering precise fit and maximum protection.

• OTC Guards: Affordable but less durable; may worsen jaw alignment if ill-fitting.

4. Clinical Indications for D7840

Bruxism (Teeth Grinding)

• Symptoms: Worn enamel, tooth fractures, morning headaches.

• Solution: A hard occlusal guard prevents further damage.

Temporomandibular Joint Disorder (TMD)

• Symptoms: Jaw pain, clicking sounds, limited movement.

• Solution: A properly adjusted splint redistributes bite force.

Sleep Apnea and Snoring

• Some occlusal guards double as mandibular advancement devices (MADs) to open airways.

5. The Process of Fabricating an Occlusal Guard

1. Diagnosis: Dentist examines bite, jaw alignment, and tooth wear.

2. Impressions: Traditional molds or digital scans are taken.

3. Lab Fabrication: A dental lab creates a custom-fit guard.

4. Fitting & Adjustments: Ensures comfort and proper function.

6. Insurance Coverage and Reimbursement

• Dental Insurance: Often covers 50-80% of D7840 costs.

• Medical Insurance: May apply if linked to TMJ or sleep apnea.

• Out-of-Pocket Cost: $300-$800 for custom guards.

7. Maintenance and Care

• Clean daily with a toothbrush and mild soap.

• Store in a ventilated case to prevent bacterial growth.

• Replace every 2-5 years depending on wear.

8. Common Problems and Solutions

• Discomfort: Minor adjustments by the dentist can improve fit.

• Excessive Wear: Upgrade to a harder material if needed.

9. Alternatives to D7840 Occlusal Guards

• Botox Injections: Reduces muscle activity in severe bruxism cases.

• Physical Therapy: Stretching exercises for TMJ relief.

10. FAQs About D7840

Q: Can I use an OTC guard instead?
A: For mild cases, yes, but custom guards offer better protection.

Q: Does insurance cover D7840?

11. Conclusion

The D7840 dental code represents a vital treatment for bruxism, TMJ disorders, and dental protection. Custom occlusal guards provide superior comfort and durability compared to OTC options.
