Whether a tooth broken in half can be remedied or not, it is necessary to go to the hospital to have an examination at a professional dental office, and the doctor will take different methods to remedy the tooth according to the part and degree of the breakage, and the common methods are veneer repair, root canal treatment, crown restoration and extraction. 1. Veneer restoration: If the tooth is only fractured and the root is not damaged, the tooth can be restored with a veneer, which is bonded to the labial surface of the tooth to repair the damage and improve the aesthetics. 2. Root canal treatment: For patients who have penetrated the pulp, it may be necessary to do root canal treatment first. The purpose of root canal treatment is to remove as much as possible the necrotic tissues, bacteria and their products in the root canal, and to form a certain taper, and then fill the root canal with sterile cementum filling material to achieve the purpose of three-dimensional filling, so as to restore the normal function of the tooth. 3. Crown restoration: If only the root of the tooth remains but all the crown is missing, it can be restored by crown restoration, using a part of the restoration to penetrate deep into the healthy root of the tooth to achieve the purpose of retention, and then on the outside of most of the missing part of the body of the tooth, full crown restoration is carried out, collectively referred to as crown restoration. 4. Extraction: If the tooth is broken to a greater extent, the possibility of remedying this situation is smaller and the tooth needs to be extracted. When a tooth is broken in half, it is necessary to go to the hospital in time for examination and treatment, so as not to delay the condition or cause adverse reactions.
