Damage to the enamel of incisors is usually due to tooth abrasion or trauma resulting in a small amount of crown loss, or it may be due to shallow caries, which can be treated by desensitization, restoration, filling and other methods. 1. Tooth abrasion: If the enamel surface of incisors is damaged due to abrasion, but the trauma is relatively light, desensitization treatment can be chosen. If the depth is deeper, piercing preparation and restoration can be performed. 2. Trauma: If it is caused by trauma, the usual brushing method must be up and down, don’t brush horizontally like pulling a big saw, and the damaged incisor enamel caused by trauma can be repaired by light curing. 3. Shallow caries: If the incisor enamel damage is caused by shallow caries, you can choose to apply fluoride composite or dental filling materials to fill the local area. It is recommended to go to the stomatology department of the regular hospital for examination as soon as possible, and carry out specific treatment according to the specific situation.
