<s>[INST] Hi, I went to the dentist a few weeks ago with an infection in the gum near my wisdom tooth. The dentist said it was hard to tell whether the wisdom tooth would have room to come up and therefore I might have to get it removed. My top wisdom tooth seems to be biting down on my lower gum near the new wisdom tooth and the gum is a little swollen and has a white ulcer on it. Is this a sign of infection? The last infection had blood and pus however this one doesnt.It is quite sore to chew and open my mouth fully. I dont have the funds to visit my dentist right now..What can I do until I can go and visit my dentist? [/INST] Thanks for your query, I have gone through your query. The pain, swelling and limited mouth opening could be because of the gum infection over the wisdom tooth (periodontal infection leading to space infection. Consult an oral physician and get a radiograph done to rule the amount of space present for the tooth to erupt if space is there for the tooth to erupt then the gum covering over the wisdom tooth can be removed. If the space is not available then you have to get the wisdom tooth removed. You can take a course of antibiotics and analgesics like amoxicillin 500 mg and metronidazole 400 mg TID for 5 days. Do saline gargling. I hope my answer will help you, take care. </s>
