Is the left cheek painful tooth inflammation

Root canal therapy is the most effective treatment for periodontitis, and it is recommended that patients with periodontitis should take antibiotics orally to relieve the pain caused by inflammation of the teeth. In addition, the pain on the left cheek may also be a local ulcer on the left cheek mucosa, which may be caused by eating spicy and irritating food for a long time. It may also be caused by traumatic ulcers caused by residual roots, residual crowns, caries or malposition of teeth on the left cheek, which often bite the left cheek mucosa. Ulcers can cause redness, bleeding and ulceration of the cheek mucosa, thus causing severe pain and seriously affecting eating and speaking.
