My husband is ready for his third round of chemotherapy for small cell carcinoma and yesterday mentioned that his eyetooth and the crowned tooth adjoining are very tender and sore.  No swelling or open sores?  We wonder if it isnt a side effect of the chemo?
Thanks for your question on Chat Doctor. I can understand your situation and problem. No, tooth and gum tenderness are not direct side effects of chemotherapy. But it can be indirect side effects of chemotherapy. Chemotherapy causes immunosuppression. So patient on chemotherapy is more prone for opportunistic infections. So possibility of tooth and gum infection is high in his case. Better to consult dentist and rule out infection and start appropriate treatment.
