Introduction
In general, whether swelling of the gum tissue at the back of the tooth can heal on its own, and how long it takes to heal, depends on the cause and severity of the swelling. Swelling caused by mild irritation may resolve spontaneously within 1–2 weeks, while more severe inflammation or underlying dental problems often do not heal without treatment. Daily oral hygiene is important: rinse the mouth after meals, brush teeth thoroughly in the morning and evening, and reduce the buildup of food debris.
一般情况下，牙最里面的肉肿了能否自愈及自愈时间，取决于肿胀Cause和严重程度，轻微刺激引发的肿胀可能1-2周自愈，炎症较重或有牙齿问题时通常难以自愈。具体分析如下：
若肿胀是因进食时食物摩擦、短暂咬伤等轻微刺激导致，且口腔卫生良好，身体抵抗力较强，肿胀可能在1-2周内逐渐消退。期间保持口腔清洁，避免刺激肿胀部位，有助于恢复。但如果是智齿萌出受阻、智齿冠周炎、牙龈炎或龋齿引发的炎症，肿胀通常难以自行消退，若不干预，还可能加重，出现疼痛加剧、流脓等情况。
日常需注意口腔Nursing，饭后及时漱口、早晚认真刷牙，减少食物残渣堆积。若肿胀持续不缓解或出现疼痛加重，应及时排查病因，通过专业Treatment消除炎症、解决牙齿问题，避免Symptoms进一步发展影响口腔Health。
