Can Grinding Teeth Cause Root Canal

There has been a significant increase in the number of people grinding and clenching their teeth at night, while they are asleep. This condition is known as “bruxism”. 70% of bruxism cases are attributed to stress. 10% of America’s population is suffering from bruxism and this number is growing higher every day. 30% of our population will exhibit aching or clicking in their jaw at some point in their lives. This condition is known as temporomandibular joint dysfunction (TMJD).

Root canal specialists at Midtown Endodontist NYC see more and more cases that need his expertise. In the past, most cases came from decayed teeth; now a number of patients are coming with cracked teeth. What is happening?

What Happens When You Grind Your Teeth

1. Tips of the teeth look translucent.
2. Teeth look flat.
3. Sharp edges of teeth become dull.
4. The occlusal plane flattens out.
5. Interocclusal distance between tip of nose and chin is diminished.
6. Erosion or worn teeth or teeth start to get brown (exposed dentin).
7. Enamel (strong, thin white outer layer) is literally ground away.
8. You wake up with headaches or migraines regularly.
9. Chronic earaches.
10. Lockjaw.
11. Loose teeth.

Etiology of Root Canal Therapy from Grinding

Teeth are composed of:

• An outer layer of thin strong, protective enamel
• A middle layer of dentin that comprises the bulk of the tooth and is more organic than enamel
• An inner layer called the pulp chamber that houses an artery, vein, and nerve of the tooth

Stress causes grinding. Grinding causes cracks in the tooth. Cracks cause infection and necrosis (death) of pulp tissue. Infection of pulp tissue leads to pain and possible abscess formation.

If decay, a crack, a severe chip, or fracture caused by trauma from grinding invades the sanctity of the pulp chamber, bacteria will come in, and the pulp will become infected. This results in a classic, painful toothache. Root canal therapy removes the infected tissue inside the tooth, sterilizes the chamber, and fills the chamber with an inert material (gutta percha) that prevents reinfection.

How to Prevent Grinding

• Wear a nightguard
• Reduce stress with:
  • Regular exercise
  • Cognitive Behavioral Therapy
  • Mindful meditation
  • Deep breathing exercises
  • Yoga
• Bi-Annual checkups with your dentist

Other Dental Manifestations from Stress

1. Bleeding gums—gingivitis, periodontitis
2. Bad breath
3. Acid reflux
4. Cheek biting
