Teeth Clenching and Grinding: Understanding the Risks and Solutions
Teeth clenching and grinding, often done unknowingly, can cause significant damage to your teeth. While it may occur both during the day and night, many people don’t realize the harm these habits can cause until it’s too late. Dr. David Okano, a periodontist with 30 years of experience and assistant professor at the University of Utah School of Dentistry, explains the risks and provides solutions.
Clenching vs. Grinding
Dr. Okano explains that clenching and grinding are similar but not identical. Clenching refers to simply gritting your teeth together, while grinding involves moving the teeth back and forth. Both actions wear down tooth surfaces and can lead to fractures and bone loss around the teeth’s roots. Grinding is often more problematic at night due to the prolonged pressure and intensity.
Why Do People Grind and Clench?
Stress is one of the main triggers for teeth clenching and grinding. Dr. Okano notes that it’s common to see students or individuals under work-related stress engaging in these habits. Some may clench their teeth during the day without realizing it.
Damage from Clenching and Grinding
The damage caused by these habits includes worn-down teeth, cracks, and even tooth loss. Dr. Okano compares this to pushing a post into the ground: continued pressure gradually loosens it. Over time, grinding or clenching can cause the bone supporting the tooth to weaken, eventually leading to tooth loss.
Solutions for Clenching and Grinding
One common solution is wearing a mouthguard. Dr. Okano explains that mouthguards help reduce damage by acting as a cushion between the teeth. They don’t stop the grinding or clenching habit itself but prevent the damage that could otherwise result. The mouthguard needs to be replaced periodically, depending on how often you grind or clench your teeth. Your dentist can help monitor its effectiveness.
TMJ and Other Issues
Clenching and grinding can also affect your temporomandibular joint (TMJ), causing jaw pain, muscle spasms, and even headaches. A mouthguard can help alleviate these symptoms by reducing pressure on the jaw and improving comfort.
When to See a Dentist
If you suspect you’re grinding or clenching your teeth, symptoms may include a feeling of tiredness or discomfort in your jaw and face, especially in the morning. It’s essential to visit your dentist, who can assess the situation, check for any damage, and recommend appropriate treatment.
