When the polyp grows in the mouth, it can take the measures of making inlay restoration, applying composite resin, silver amalgam and other filling, and root canal treatment, subgingival scraping, etc., as follows: 1.Making inlay restoration: grinding and changing the high point of the shape of the adjacent surface of the tooth, expanding the outreach gap, avoiding food embedding, causing gingival hyperplasia, making inlay restoration if necessary, and establishing good adjacent relationship. 2.Applying composite resin, silver amalgam and other filling Silver amalgam filling: when the cavity of dental crown is formed, accompanied by gingival polyp, the polyp can be grinded out, the decayed tooth tissue can be removed, and the cavity can be prepared and filled with composite resin and silver amalgam. 3.Root canal treatment: when the pulp polyp is formed, the pulp and polyp can be removed directly under general anesthesia, and the root canal canal can be rinsed thoroughly with 3% hydrogen peroxide solution after root canal preparation to complete root canal treatment and close the cavity. 4.Subgingival scraping If a large amount of calculus is attached to the root surface of the tooth and stimulates the formation of granulation tissue, subgingival scraping can be performed to completely remove the calculus and granulation tissue, and tetracycline gel can be placed after rinsing the periodontal pocket to promote anti-inflammation.
