Biting out a meaty lump inside the cheek is the appearance of a meaty lump on the inner wall of the mouth, which may be caused by traumatic irritation, inflammatory polyps in the mouth, or chronic periapical inflammation. General treatment, root canal treatment, surgical treatment and so on can be carried out according to the specific causes. 1. Traumatic stimulation: in daily life, if you eat too fast, it is easy to bite the inner wall of the mouth, resulting in the appearance of bumps on the inner wall of the mouth, generally can not be treated, and can be recovered on its own; if the bumps are bitten, there is pain, maintain oral hygiene, to avoid infection. 2. Inflammatory polyps: the oral cavity with residual roots and crowns, tooth tip or poor repair or scrape the buccal lip mucosa, repeated trauma stimulation of the mucosa will lead to localized hyperplasia, the formation of inflammatory polyps, thus feeling the mouth with bumps. This is when the local irritant needs to be removed. Inflammatory polyps usually do not absorb on their own and need to be surgically removed. 3. Chronic periapical inflammation: Chronic periapical inflammation refers to the root canal due to the presence of long-term infection and pathogenic stimuli, the tissues around the root tip show chronic inflammatory reaction, manifested as inflammatory granulation tissue formation and alveolar bone destruction. Repeated stimulation of apical inflammation causes destruction of the bone wall, inflammation spreads, and granulation may appear at the gingival mucosa near the root. Root canal treatment is required, and if the result is not satisfactory, apical surgery or extraction of the affected tooth is feasible. In daily life, you should chew and swallow slowly when eating, and eat light food in your diet to minimize the irritation to the wound area.
