The root of the tooth grows a hard bag like a bone, may be related to chronic apical inflammation to form a fistula, apical cyst, jawbone tumor, according to the cause of root canal treatment, surgical treatment, etc..
1.apical fistula: due to acute apical inflammation can make the periapical tissue swelling, the formation of abscess, if not treated in time, can be turned into chronic apical inflammation can be accompanied by the formation of local fistula, manifested in the apical area with a hard bag. At this time, feasible root canal treatment, at the same time can do fistula excision.
2. apical cyst: due to periapical granuloma, chronic inflammation stimulation, caused by epithelial hyperplasia in the periodontal membrane as a group, the central liquefaction can form periapical cysts, cysts continue to increase in size, destroying the buccal side of the wall of the bone, can be manifested as the apical area of the hard bag. At this time, root canal treatment should be carried out after apical cyst excision, plus apicoectomy.
3. Jaw bone tumor: when the jaw bone tissue lesions can form jaw bone tumor, manifested as jaw bone bulging, at this time, feasible jaw bone tumor resection.
When the root of the tooth grows a hard bag, you should consult the doctor in time, improve the examination, clarify the cause and diagnosis, and standardize the treatment under the guidance of professional doctors.
