Children’s tongue is abraded by the tooth pain, may be due to calculus, tooth damage and other factors. It is recommended that the child go to the hospital, according to the cause of targeted treatment. 1. Dental calculus: After the child’s dental calculus is removed, the surface of the teeth is uneven, so that the tip of the child’s tongue is abraded by the teeth resulting in pain. It is recommended that children go to the hospital in time for supragingival scaling and subgingival scraping, etc., to completely remove the calculus and plaque on the teeth. 2. Damaged teeth: If there are sharp points on the child’s teeth, the tip of the tongue will be abraded when touched, resulting in pain.

If the tooth is damaged due to dental caries, it is recommended to carry out filling treatment in a timely manner, or take inlay restoration surgery to restore the form and function of the tooth and improve the symptoms. It is also recommended that children pay attention to oral hygiene, brushing and rinsing before and after meals, so as not to breed bacteria, resulting in tooth pain.
