###Human: I have swelling and tooth pain. Can this be due to dislodged filling? ###Assistant: Hello. There is a swelling. It means that it still has an infection. Please do not use a warm application in infection side. You need a dental check up as soon as possible. Your dentist will take an X-ray and see the infected area after he or she decides treatment (either root canal treatment or extraction of the tooth) followed by antibiotics. So I suggest you please see your dentist as soon as possible because our smile matters. Periapical abscess due to deep dental caries. Clinical examination and dental X-ray. Periapical abscess, dental caries, perioendo lesion. Periapical abscess. Root canal or extraction (decided after clinical examination). Avoid hot food, pressure on the affected side.
