In the face of grinding teeth, can we only do nothing?

Generally speaking, molars have three different classifications.

1, bruxism at night

Changing teeth at night is the most common, which is mainly manifested in the grinding and knocking sound of teeth when sleeping at night, sometimes accompanied by creaking sound.

2, grinding teeth during the day

In addition, some small partners' symptoms of grinding teeth appear during the day, showing involuntary gritting of the teeth.

3. Mixed type

That is to say, in both cases, there are symptoms of grinding teeth.

Harm of molars

Long-term grinding will cause tooth wear, sensitivity to cold, hot, sweet and sour, affect the relationship between chewing and occlusion, damage the tissues around the teeth, tooth pain, tooth loosening and so on. And grinding teeth at night may also lead to mandibular joint disorder.

Tips for judging molars

Most people don't realize they are grinding their teeth. So, how do you know that you grind your teeth at night?

1. Dental examination found that the occlusal surface and adjacent surface were seriously worn.

2, periodontal, alveolar bone, gingival atrophy, tooth loosening, displacement and other changes.

3. During the day, the masticatory muscles are tired and the bite is weak.

I feel pain in my face and neck when I get up in the morning.

Why grind your teeth?

1, the teeth are not coordinated.

The disharmony of occlusal relationship is considered to be a major factor of bruxism, including tooth dislocation, tooth defect or too long, long-term unilateral chewing and so on.

Step 2 be nervous and anxious

Mental stress is one of the causes of bruxism. Emotional tension, excessive fatigue, mental tension, excessive tension or excessive excitement during the day often lead to inability to sleep peacefully at night. After falling asleep, although most of the cerebral cortex is in a state of inhibition, some of it is still in an excited state, which leads to the contraction of masticatory muscles and grinding teeth.

3. Disease stimulation

Intestinal parasite infection, gastrointestinal dysfunction, endocrine disorders, allergic diseases, vitamin D deficiency rickets, hyperuricemia, hyperthyroidism bladder stress and so on may all cause bruxism. When children eat too much and have indigestion, the toxins secreted by bacteria in the gastrointestinal tract are absorbed and stimulate the cerebral cortex, which makes the cerebral cortex excited or inhibited out of balance and produces night molars. Active treatment of primary disease can prevent bruxism.

4. Local stimulating factors

Periodontal disease is also closely related to bruxism. It may be that there is biofeedback between the central nervous system and mandibular proprioceptors. Local stimulation gives wrong information to the central nervous system, causing involuntary muscle tension, which leads to bruxism. Studies have shown that some patients' molar symptoms disappear or improve with the cure of periodontitis.

How to treat molars?

1, psychotherapy

Eliminate symptoms by eliminating tension, eliminating unnecessary worries and arranging work reasonably.

2, muscle relaxation therapy

To control bruxism by relieving excessive muscle tension, the commonly used methods are: the application of muscle relaxer, physical therapy, training of physiological function of masticatory muscles, massage, audio-visual suggestion and so on.

3. Adjust the occlusal relationship of teeth

By adjusting and grinding a small amount of tooth tissue, the occlusal interference can be relieved, and the occlusal balance relationship can be established, so as to achieve the physiological balance between teeth and jaws, masticatory muscles and temporomandibular joints, eliminate bruxism, and correct the habit of unilateral chewing, biting pencils and chewing gum of patients with dentofacial deformity.

Step 4 use a bite plate

The purpose is to protect teeth and reduce tooth wear, which is the most acceptable method for doctors and patients at present. It can obviously prevent tooth wear, but it can't treat bruxism.
