Teeth concave inward is usually caused by congenital dysplasia, tooth wear, etc. It can be improved by wearing orthodontic appliances and changing the way of brushing teeth.
1. Congenital dysplasia: the teeth may be concave during the period of milk teeth and the period of alternation between milk and permanent teeth, which can be improved by wearing orthodontic appliances, which can naturally push the teeth to move towards the inner side of the lips, thus expanding the width of the dental arch and stimulating the jawbone to develop more perfectly.
2. Tooth wear: it may be that the patient has bad habits such as biting the lower lip, spitting out the tongue, or brushing horizontally for a long time, which will cause irritation to the surface of the teeth, and may cause the teeth to be concave inward, so the patient can change the bad way of brushing, and brush vertically, and can use desensitization toothpaste to prevent tooth sensitivity, and if the tooth wear is serious, it may lead to pulpitis, and root canal treatment is needed.
Patients whose teeth are concave inward are advised to go to the dentist for examination in time to determine the cause of the disease before treatment. Usually, they should maintain good oral hygiene, brush their teeth and rinse their mouths diligently, and do not often consume foods that are damaging to their teeth.
