There are several reasons why teeth are always clogged, and different treatment methods are adopted for different reasons. The first reason is that the gap between the teeth itself is relatively large, if this is the case, you can consider the application of crown restoration, that is, the porcelain teeth set method of treatment. After wearing the porcelain teeth, the gap will be closed and the stuffing will be better. The second reason is that there is decay in the teeth around the gap of the teeth, and it is especially easy to have food embedment, so the decayed area needs to be repaired to avoid food embedment. The third reason is that the gum tissue at the gap of the teeth is atrophied, and periodontitis patients are prone to this condition, especially prone to horizontal food embedding, and need to carry out periodontal system treatment and apply the gap brush to brush the adjacent surface of the teeth.
