Bruxism: Causes, Symptoms, Relief, Prevention of Teeth Grinding Disorder

Why do you have bruxism? 

1. Malocclusion 

Children’s teeth will go through the process of milk teeth gradually being replaced by permanent teeth. If the teeth are not aligned properly, resulting in malocclusion, it may trigger temporomandibular joint dysfunction, which will lead to teeth grinding. In addition, long-term bad biting habits can also cause teeth grinding disorder, such as long-term sideways chewing habits. 

2. Genetic factors 

If your parents have teeth grinding disorder, the probability of you having teeth grinding will be much higher, which suggests that there is a genetic tendency for the occurrence of teeth grinding disorder in children. 

3. Psychological factors 

Some scholars have concluded that patients with teeth grinding disorder have higher levels of catecholamines, and catecholamines are closely related to human anxiety, and children with anxiety disorder treated by psychological or medication have their anxiety and teeth grinding disorder relieved. High mental tension, stress, overwork, depression, and easily provoked are also associated with nighttime teeth grinding. 

4. Other causes 

Zinc deficiency, B vitamins, vitamin D, and gastrointestinal disorders could lead to teeth grinding.

  1. Pain in the jaw and facial muscles 
  2. Ear pain 
  3. Restriction of mouth opening 
  4. Interrupted sleep 
  5. Disruption of partner’s sleep by making noise 
  6. Loose teeth 
  7. Inflammation and recession of the gums 

Long-term symptoms of teeth grinding

  2. Tooth wear and fracture 

How to relieve the adverse effects of teeth grinding? 

1. Wet a washcloth or face towel with warm water, wring it out and apply it to both sides of your jaw for a few minutes. A bath or shower with warm water has a similar effect and can help you relax before bedtime. 
2. Eat soft foods and less chewing gum and hard bread to prevent jaw muscles from tightening. 
3. Wear anti-grinding pads at night to cushion the pressure from teeth clashing. 
Although the pad won’t stop you from grinding your teeth, it will at least protect your teeth and jaw. It is made of soft plastic that cushions the pressure of your teeth as you grind them.
