A small piece of tooth loss can be treated without special treatment if there is no particular effect. If a small piece of the tooth has fallen out, resulting in a sharp localized tooth, lip scratches and other discomforts, you can go to the hospital for treatment. Localized shimming can be considered to round off the sharper broken ends. If the lost tooth has been examined by the doctor and has some impact on the shape of the tooth, a profile repair with light-cured resin may also be considered. Therefore, if the tooth is only a small piece and has no particular impact, no special treatment can be done. If you feel that it has an impact on your life or there is a relatively sharp break, you can also go to the hospital for treatment.
