<s>[INST] Hello!I have what I believe is an impacted wisdom tooth. The actual tooth part doesnt start until almost my gumline. The other day, I bit too hard into the gum that is still on the impacted wisdom tooth and created a sore lump. Now I cannot chew on the left side of my mouth or close my mouth all the way. [/INST] With your query, as you mentioned that you have impacted tooth that means the tooth hasn't reached to its causal level and still covered by gum that is technically called as periodontal flap. Coming to your swelling I mean the lump could be a periodontal abscess which may be due to forceful food impaction in to gingival called as pseudo pocket. Treatment for this are by two means initially it has to get irrigated by an antiseptic solution then either you should go for a procedure called operculectomy which means removal of gingival or gum that is present over the tooth. This decision will be made by examining the tooth eruption status by radiograph and your age. In some instances if they decide tooth development is complete and chances of recurrence is more than you may have to undergo extraction for the impacted tooth.  I would suggest you to go and visit oral surgeon for time being you can start using antibiotics along with painkillers and visit dentist as early as possible for complete treatment. It is unethical to prescribe antibiotics without knowing your Chat Doctor. Hope this is informative </s>
