<s>[INST] Hello, I already have a bad tooth in the back of my mouth that needs to be extracted but I dont have the money yet. My tooth has been hurting all evening and I told my boyfriend to not point the fan towards our faces tonight because it will make the tooth begin to hurt again. Well, he thinks that sleeping under a fan has absolutely nothing to do with sleeping under a fan because hes done it for years and its never caused his teeth to hurt. Please tell me what to tell him. [/INST] Hello, Thanks for consulting Chat Doctor, Read your query, as you have severe toothache Donna worry this pain in tooth not because of fan this pain is due to presence of carious tooth or decayed tooth which has infection present in region of pulp it can lead to formation of pus also at apex of root, so I will suggest you to consult your dentist and go for removal or treatment of tooth as early as you can manage. For pain, you can take analgesic tablet like dispensable Paracetamol tablet or Retool DT contemporary relief. Do Luke warm saline gargle 3 - 4 times in day, Maintain proper oral hygiene. Hope it will help you. Wishing you good health.  </s>
