  • The Effects of Night-Time Teeth Grinding

Teeth grinding, also known as bruxism, is when people clench their jaws and cause their upper and lower teeth to rub together. This usually happens while people sleep, which makes the habit difficult to break. Bruxism can also occur while awake, although it is most common while sleeping.

Aside from being a contributing factor to tooth decay and pain, bruxism can even affect bone structure and facial muscles. People with severe bruxism sometimes end up breaking teeth or damaging restorative dental work

If your bruxism is mild, you may not need to seek out treatment. In cases where the grinding causes you pain, it’s important to consult your dental care provider.

If you believe you are suffering from symptoms of bruxism, contact our dental office in NW Calgary today. We would be happy to treat any of your smile-related concerns. But first, acquaint yourself with everything you need to know about bruxism to determine whether you have this condition.

The Causes of Bruxism

Bruxism is actually a modern mystery. Doctors don’t really understand what causes bruxism, but many suspect that it is a result of many genetic, psychological, and physical factors. Sleep bruxism is thought to be caused by sleep arousal, whereas awake bruxism may be caused by emotions like anxiety or stress.

Here are some of the symptoms of bruxism:

  • Noisy clenching or grinding. You may be able to tell if you sleep with someone else and the sound wakes them up
  • Chipped, broken, or flattened teeth
  • Tooth sensitivity or incessant pain
  • Damage on the inside of your cheek caused by chewing
  • Weakened tooth enamel
  • Pain that feels like it originates from your ear
  • Headache beginning in your temples
  • Sore jaw muscles or lock-jaw
  • Disrupted sleep

It’s crucial that you see a dentist if you are routinely experiencing any of these symptoms. 

Factors That Increase Your Risk of Developing Bruxism

A number of things can cause the onset of bruxism. Stress is one of the biggest contributing factors. Other related emotions can cause it as well, like anxiety or anger. Your personality can even affect whether or not you struggle with bruxism. If you are a competitive or hyperactive type, you are more likely to develop the condition.

Teeth grinding is most present in children, and in childhood cases, it usually disappears by adulthood. Sleep bruxism is common if you have a family history of it. It is also commonly associated with mental disorders or medical conditions like:

  • Dementia
  • Parkinson’s disease
  • Epilepsy
  • Night terrors
  • Sleep apnea
  • ADHD

Although it is not common, teeth grinding can be a side effect of some medications like antidepressants. You are at an increased risk of bruxism if you:

  • Habitually smoke
  • Drink alcohol
  • Use recreational drugs
  • Drink caffeine

Evaluation & Diagnosis

Bruxism is sometimes a slow progression, so your dentist may need to examine your teeth several times to determine if there are any prominent changes to the structure of your teeth. From here, they can determine whether or not you need treatment.

To determine your candidacy for treatment, your dentist will ask general questions about your dental health, daily routine, sleeping habits, and medications you are taking. They will look for tenderness in your jaw muscles, damaged or broken teeth, or damage to the inside of your cheeks.

Getting a bruxism exam may even reveal some other disorders that can cause jaw pain. That’s another reason why it is vitally important that you consult a dental professional when dealing with any of these symptoms.

Treating Bruxism

Generally, people don’t require treatment for teeth grinding because it is either an outgrown habit, or doesn’t reach a point of severity that calls for treatment. In severe cases, there are a number of dental procedures, medications, and therapies to help with the symptoms of bruxism:

  • Mouth guards or splints. These small tools are designed to separate your teeth and prevent damage caused from clenching, rubbing, and grinding. They are usually made of acrylic and are fitted over lower or upper teeth.
  • If the grinding has caused increased tooth sensitivity or diminished your ability to chew properly,, your dentist might need to reshape the surface of those teeth or install crowns.
  • Muscle relaxants are commonly prescribed to people with bruxism. Your doctor might recommend that you take these before bedtime.
  • In cases where the bruxism is caused by a mental disorder, your doctor might prescribe anti-depressants to combat the symptoms of anxiety or depression, thus easing symptoms of teeth grinding.
  • Botox injections are helpful for people who don’t respond to other treatments. The injections freeze the jaw muscle which helps with clenching and grinding.

Anxiety is commonly a cause of teeth grinding. By treating the anxiety, usually bruxism disappears as well. Engage in activities that promote relaxation or enlist the help of a therapist. 

Ways to Treat Bruxism at Home

While it is important that you visit a dentist if you are experiencing these symptoms, here are some home remedies to ease your discomfort before your dentist appointment:

  • Don’t drink caffeine or tea late at night and avoid drinking alcohol too late. These substances can cause bruxism flare-ups.
  • Make sure your sleep habits are healthy. If you are dealing with any sleep disorders, ensure that you treat those because they may be causing you to grind your teeth.
  • Manage your stress by doing things that relax you, like meditating or listening to music.
  •  If you sleep with a partner, ask them to keep note of any grinding sounds that you may make while you’re sleeping. When you do get a chance to visit a dentist, you can relay this information to them.
  • Schedule dental exams regularly. A lot of dental issues can be caught before the point of severity if you see your dentist often. 

These treatment methods are easy ways to prevent your own bruxism condition. However, follow up with a dentist appointment to make sure your condition is actually decreasing.
