A tooth that is half lost and has flesh growing inside it that bleeds may be caused by pulpal polyps. If there is much tissue left in the tooth, a thorough root canal can be performed to preserve the tooth, but if there is too little tissue left in the tooth, it should be extracted. Pulp polyps are a manifestation of chronic pulpitis. Pulp polyps are painless when touched but bleed easily. 1. If the apical foramen is well developed, a thorough root canal treatment can be performed to remove the enlarged pulp, fill the root canal, and crown the tooth after filling. 2. For teeth with great damage to the profile of the tooth surface and crown, there is no value in preserving the tooth, and the tooth should be extracted together, and the tooth can be subsequently restored by implantation. To summarize, if the tooth has a lot of remaining tissue, you can perform a perfect root canal treatment to retain the tooth, and later wear a crown to restore the tooth. For teeth with a lot of damage, they should be extracted and subsequently restored with dental implants.
