How can bruxism damage my child’s teeth?
Bruxism is characterized by the grinding of the upper jaw against the lower jaw. Especially in cases where there is vigorous grinding, the child may experience moderate to severe jaw discomfort, headaches, and ear pain. Even if the child is completely unaware of nighttime bruxing (and parents are unable to hear it), the condition of the teeth provides your pediatric dentist 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, children 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. Pediatric dentists also notice that children tend to brux more frequently in response to life stressors. If the child is going through a particularly stressful exam period or is relocating to a new school for example, nighttime bruxing may either begin or intensify.
Children with certain developmental disorders and brain injuries may be at particular risk for grinding. In such cases, your pediatric dentist may suggest botulism injections to calm the facial muscles, or provide a protective nighttime mouthpiece. If the onset of bruxing is sudden, current medications need to be evaluated. Though bruxing is a rare side effect of specific medications, the medication itself may need to be switched for an alternate brand.
