Surgical treatment: It can be treated by gingivectomy, osteotomy, guided regeneration, which aims to restore the patient’s normal gingival physiology so that the periodontal tissues can produce new attachments. Regenerative membranes are also utilized to keep the epithelial cells and connective tissue out, allowing the periodontal cells and alveolar bone cells to take the lead in growth. Also in your life, avoid spicy, stimulating foods or sweet, acidic foods. Eat more foods or fruits rich in vitamin D, which can effectively make the teeth absorb more calcium.
