If the teeth are often blocked, first of all, we should exclude whether the blockage is caused by cavities on the surface of the teeth. You can go to the hospital for X-ray examination to find out whether there is cavity on the adjacent surface, and generally there is no way to judge through the naked eye. If there is a cavity, as long as the resin material is filled in time, the cavity will not appear again in the future. Secondly, if there is no cavity, but the gap of the tooth is gradually increasing. You should be alert to the occurrence of periodontitis, which leads to the recession of alveolar bone and gum recession. Once periodontitis appears, you must go to the hospital in time to have periodontal scraping treatment by the doctor. Then you can use a dental flosser to thoroughly clean out the soft tartar and plaque in the gaps between your teeth.
