Suggestion: gingival bleeding after porcelain teeth are made. It is more likely that the edge of porcelain teeth is imperfect, cracks appear, or it is too long, which leads to the accumulation of periodontal plaque, and the bacterial reproduction inside causes gingival inflammation and bleeding. In addition, it is not ruled out that there is a problem with the material of porcelain teeth, which stimulates gingival inflammation and leads to gingival bleeding. The treatment is periodontal scaling and plaque removal. If necessary, remove the porcelain teeth. And usually need to pay attention to good oral hygiene. Periodontal scaling is performed regularly.
