[|Human|] Can penicillin cause inflamed gums and sores?  24 hours after starting treatment with Penicillin for strep throat, I started with inflamed gums that bleed with brushing and small sores throughout my mouth. Wondering if its caused by the penicillin or the infection. Throat is improving, mouth is worsening.
[|AI|]  Hello. I read through your query and I must say that as such the penicillin doesn't have side effect on the gums, but it can cause change in taste of the mouth ulceration in some cads, but these are all seen in long application of penicillin. For some people there can be allergy to penicillin which can result in some sort of probs like this, but it can result in skin rashes etc. so I think it won't be due to allergy. I suggest you to Chat Doctor. Be cool and stay happy.That's the best medicine for any disease. Hope your benefitted something from this reply. Have a healthy day!!!
