Alveolar bone resorption is related to apical periodontitis and periodontitis, if it is caused by apical periodontitis, you can choose root canal treatment, but if it is caused by periodontitis, you can choose scaling or surgical treatment, no need for root canal treatment. 1. Root canal treatment is possible: if apical periodontitis leads to suppurative necrosis of the nerve, inflammation builds up in the apical area, making the alveolar bone destroyed, in this case, root canal treatment should be carried out in time to remove the infection in the root canal and strictly control it. If the inflammation in the root canal is completely eliminated, then the alveolar bone in the apical area can be restored by itself. 2. Can not be root canal treatment: periodontitis caused by alveolar bone resorption, we should actively carry out full-mouth ultrasonic scaling and subgingival scaling, remove calculus, diseased bone and granulation tissue, control inflammation in order to reduce gum bleeding. In severe cases, periodontal flap surgery is required to implant bone powder and periosteum to promote the formation of hard tissue. It is recommended to go to the regular dental hospital in time after the emergence of alveolar bone resorption, usually need proper oral health care, you can wash your teeth once a year, and go to the regular hospital stomatology examination every six months. If you have periodontal disease, you should receive regular treatment to avoid delays.
