A large swollen gum does not go away on its own. A large swollen gum is usually due to inflammation of the gums or an abscessed gum caused by periapical infection. Periodontal uncleanliness caused by calculus stimulates the gums to produce redness and swelling, indicating that there is an inflammatory reaction in the swollen packet, which needs to be cleaned and treated with anti-inflammatory treatment, etc. before it can heal. Sometimes, although the swollen pack may rupture and drain the pus, it can only provide temporary relief and does not cure the root cause and is prone to recurrence. It is also possible that the swelling of the gum is also due to the decay of the tooth, which produces an impaction of food to press the gum. It may also be due to apical inflammation of the tooth, causing swelling in the gum area of the root tip. If it is caused by periapical inflammation, root canal treatment is required. The appearance of swollen gum pockets should be promptly examined by dental films and other examinations in the dentistry department to clarify the cause of the disease. Pay attention to oral hygiene in daily life, brush your teeth in the morning and evening, and rinse your mouth with warm salt water after meals, etc.
