Bruxism, or the grinding of teeth, is remarkably common in children and adults. For some, this tooth grinding is limited to daytime hours, but nighttime grinding (during sleep) is most prevalent. Bruxism can lead to a wide range of dental problems, depending on the frequency of the behavior, the intensity of the grinding, and the underlying causes of the grinding.
A wide range of psychological, physiological, and physical factors may lead people to brux. In particular, jaw misalignment (bad bite), stress, and traumatic brain injury are all thought to contribute to bruxism, although grinding can also occur as a side effect of certain medications.
What are some symptoms of bruxism?
In general, parents can usually hear intense grinding – especially when it occurs at nighttime. Subtle daytime jaw clenching and grinding, however, can be difficult to pinpoint. Oftentimes, general symptoms provide clues as to whether or not the child is bruxing, including:
Frequent complaints of headache.
Injured teeth and gums.
Loud grinding or clicking sounds.
Rhythmic tightening or clenching of the jaw muscles.
Unusual complaints about painful jaw muscles – especially in the morning.
Unusual tooth sensitivity to hot and cold foods.
How can bruxism damage my teeth?
Bruxism is characterized by the grinding of the upper jaw against the lower jaw. Especially in cases where there is vigorous grinding, you may experience moderate to severe jaw discomfort, headaches, and ear pain. Even if you are completely unaware of nighttime bruxing, the condition of the teeth provides us with important clues.
First, chronic grinders usually show an excessive wear pattern on the teeth. If jaw misalignment is the cause, tooth enamel may be worn down in specific areas. In addition, people who brux are more susceptible to chipped teeth, facial pain, gum injury, and temperature sensitivity. In extreme cases, frequent, harsh grinding can lead to the early onset of temporomandibular joint disorder (TMJ).
What causes bruxism?
Bruxism can be caused by several different factors. Most commonly, “bad bite” or jaw misalignment promotes grinding. We also notice that people tend to brux more frequently in response to life stressors. If you, or your child, is going through a particularly stressful period, nighttime bruxing may either begin or intensify.
How is bruxism treated?
In general, the cause of the grinding dictates the treatment approach. If the teeth are badly misaligned, we may take steps to correct this. Some of the available options include: altering the biting surface of teeth with crowns, and beginning occlusal treatment.
If bruxing seems to be exacerbated by stress, we may recommend relaxation classes, professional therapy, or special exercises. We may also provide muscle relaxants to alleviate jaw clenching and reduce jaw spasms.
In cases where teeth are sustaining significant damage, we may even suggest a specialized nighttime dental appliance such as a nighttime mouth guard. Mouth guards stop tooth surfaces from grinding against each other, and look similar to a mouthpiece a person might wear during sports. Bite splints, or bite plates, fulfill the same function, and are almost universally successful in preventing grinding damage.
Here, at Village Green Dental Center, there are many guards we can offer, including ones that help Sleep Apnea and snoring patients!
