The reason why 2-year-old babies grind their teeth at night

Night is the best rest time for our body. The same goes for children. They must have a good sleep to grow better. Therefore, if the baby is troubled by the problem of teeth grinding at night, parents must pay attention to it. There are many ways to treat teeth grinding. Children still need to adopt some simpler methods. Next, we will introduce in detail the reasons why 2-year-old babies grind their teeth at night.

1. Intestinal ascariasis;

2. Pinworm disease Pinworms parasitize in the large intestine of children. When the child is asleep, they crawl to the outside of the anus to lay eggs, causing itching of the anus, making the child restless at night and causing teeth grinding.

3. Overeating at dinner If children eat too much at dinner, there will still be a lot of food in their stomachs after they fall asleep. The entire digestive system has to work overtime, and the chewing muscles are also mobilized to contract involuntarily, causing bruxism.

4. Overexcitement of the nerves. Some children do not grind their teeth normally, but if they listen to exciting stories or watch TV with tense plots, they will grind their teeth during sleep. This is because their nerves are overexcited.

5. Sleeping with your head covered can also cause lack of oxygen and accumulation of carbon dioxide, which can stimulate the brain and cause nighttime bruxism. Nocturnal bruxism usually occurs due to nerve reflex after falling asleep. At this time, there is no food in the mouth and saliva secretion is low. The teeth cannot be lubricated and can only grind up and down, causing tooth wear. Nighttime bruxism causes wear on the incisal edges of the front teeth, shortening and deforming the front teeth, and grinding the occlusal surfaces of the back teeth into flat plates, which affects the chewing function of the teeth, can cause strain on the chewing muscles, and even cause damage to the periodontal tissues and temporomandibular joints; due to the wear of the enamel and exposure of the dentin, allergic symptoms such as soreness and pain occur, and in severe cases, pulpitis may occur.

The above content is an introduction to the reasons why 2-year-old babies grind their teeth at night. You can make some appropriate adjustments in diet, and the baby's behavioral activities also need to be restricted. Too much energy during the day can easily lead to teeth grinding at night, but many of them are normal physiological phenomena of growth.
