Do you have a mouth ulcer that does not seem to be healing?
Mouth ulcers are small sores that develop inside the lips, cheeks, tongue or gums. They can make eating, drinking, speaking and brushing uncomfortable. Most uncomplicated ulcers are harmless and improve within one to two weeks.
Common triggers include:
• Accidentally biting the cheek or tongue
• Burns from hot food or drinks
• Cuts caused by hard or rough food
• Irritation from a sharp tooth or rough filling
• Braces or dentures rubbing the mouth
• Stress, anxiety or tiredness
• Certain foods, medicines or nutritional deficiencies
To reduce discomfort while the area heals:
• Use a soft-bristled toothbrush
• Continue cleaning the mouth gently
• Choose soft, cool or lukewarm foods
• Drink sufficient water
• Rinse with warm salt water and spit it out
• Ask a pharmacist or healthcare professional about an appropriate pain-relieving gel or mouth rinse
Avoid spicy, salty, acidic, very hot or rough foods. Do not touch, scrape, squeeze or try to pop the ulcer. Do not place aspirin, acidic substances or unverified remedies directly on it.
Arrange a dental examination if the ulcer lasts longer than three weeks, repeatedly returns, looks different from previous ulcers, bleeds or becomes increasingly painful, red or swollen. An examination is also appropriate if the area is being rubbed by a sharp tooth, filling, brace or denture.
A persistent red or white patch, mouth lump, neck lump, unexplained mouth pain or difficulty speaking should also be examined. These signs have many possible causes and do not automatically mean cancer, but they should not be ignored.
Seek earlier care for rapidly worsening pain or swelling, fever, pus, significant illness, or difficulty eating and drinking. Difficulty swallowing or breathing requires immediate medical attention.

口腔溃疡是否迟迟没有愈合？
口腔溃疡是出现在嘴唇内侧、面颊、舌头或牙龈的小伤口，可能导致进食、喝水、说话及刷牙时感到不适。多数普通溃疡没有严重问题，并会在一至两周内逐渐改善。
常见诱因包括：
• 不小心咬伤面颊或舌头
• 过热食物或饮料造成烫伤
• 坚硬或粗糙食物造成小伤口
• 尖锐牙齿或粗糙补牙材料造成刺激
• 牙套或假牙摩擦口腔
• 压力、焦虑或疲劳
• 某些食物、药物或营养素缺乏
减轻不适及帮助愈合的方法：
• 使用软毛牙刷
• 继续轻柔清洁口腔
• 选择柔软、凉爽或温热的食物
• 补充足够水分
• 使用温盐水漱口，并将盐水吐出
• 向药剂师或医疗专业人员咨询合适的止痛凝胶或漱口水
应避免辛辣、过咸、酸性、过热或粗糙的食物。不要触碰、刮擦、挤压或尝试挤破溃疡，也不要将阿司匹林、酸性物质或未经证实的偏方直接放在患处。
若溃疡持续超过三周、反复出现、外观与以往不同、出血，或疼痛、发红及肿胀不断加重，请安排牙科检查。若患处受到尖锐牙齿、补牙材料、牙套或假牙摩擦，也应接受检查。
持续的口腔红斑或白斑、口腔肿块、颈部肿块、不明原因的口腔疼痛或说话困难，也应接受检查。这些迹象可能由多种原因造成，并不代表一定是癌症，但不应忽视。
若疼痛或肿胀迅速加重、发烧、流脓、身体明显不适，或进食及饮水困难，应尽早就医。若出现吞咽或呼吸困难，应立即寻求医疗帮助。
