It is usually possible to veneer a tooth with the roots inside, but it depends on the actual situation. If the root of the tooth is particularly strong, the tooth can be veneered without extraction and after root canal treatment, which can have a therapeutic effect; however, if the root of the tooth is not very strong inside the alveolar bone at the time of veneering, the root of the tooth will need to be extracted and then veneered. However, if the root of the tooth is inside and the veneer is made without extraction, it may cause the root of the tooth to have inflammation in the local area, causing local swelling and pain to occur. Therefore, it is generally recommended to extract the root of the tooth, wait for the local alveolar bone to grow flat, and then veneer the tooth according to the local situation. Therefore, it is recommended that patients go to a regular medical institution for a comprehensive assessment based on the actual situation in the individual’s mouth to choose a more suitable restoration program.
