A small hole in the incisor may be caused by caries, which can be repaired by low-speed ball drill to remove caries, calcium hydroxide restoration, and tooth preparation. 1. Low-speed ball drill to remove caries: If the incisor has formed superficial caries, a low-speed ball drill can be used to remove the caries, and then fill with resin. 2. Calcium hydroxide cushion: If the cavity is deep and the tooth is sensitive to temperature stimulation or causes soreness, calcium hydroxide can be placed at the bottom of the cavity and resin can be used to repair the defect. 3. Dental preparation: If the front teeth have large defects and the filling material is not easy to retain, dental preparation can be done to make porcelain or all-ceramic crowns to restore the anatomical shape and improve the aesthetics. When there is a small hole in the incisor, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, and carry out targeted treatment or therapy with the help of the doctor.
