What Is Bruxism?
Bruxism is a condition that causes people to clench or grind their teeth, often without realizing it. It can happen while awake or during sleep, with nighttime grinding being more common.
Over time, repeated pressure on the teeth and jaw can lead to discomfort and dental damage. Many people do not know they have bruxism until symptoms begin or a dentist notices signs during an exam.
Several factors may increase the risk of bruxism, including stress, anxiety, poor sleep, and certain medications. Sleep disorders such as obstructive sleep apnea may also contribute. Smoking, heavy caffeine use, alcohol, and stimulant drugs can make symptoms worse for some people.
Symptoms
Bruxism can affect both the teeth and the muscles around the jaw. Symptoms may come and go or gradually worsen over time.
Common symptoms include:
- Grinding or clenching teeth
- Jaw soreness or tightness
- Headaches, especially in the morning
- Sensitive or painful teeth
- Chipped, cracked, or worn teeth
- Clicking or popping in the jaw
- Facial muscle fatigue
- Trouble fully opening or relaxing the jaw
How Is It Diagnosed?
Bruxism is often discovered during a dental exam. Your provider may look for worn enamel, tooth damage, or signs of jaw strain.
They may also ask about headaches, jaw pain, sleep quality, stress levels, and medications. In some cases, additional evaluation may be recommended to check for sleep disorders or TMJ problems.
How Is It Treated?
Treatment depends on the cause and severity of symptoms. Many people improve with simple changes that reduce stress on the jaw and protect the teeth.
Common treatment options include:
- Custom night guards or mouth guards
- Stress management techniques
- Improving sleep habits
- Jaw relaxation exercises
- Limiting caffeine and alcohol
- Adjusting medications when appropriate
For severe cases that do not respond to conservative treatment, injections or specialty care may be considered. Early treatment can help prevent long-term damage to the teeth and jaw.
