These white patches (painless apthous ulcer) in my gum from last June after a molar teeth surgery. That time I used some antibiotics too. Then I used zyte,anti allergic tablet and multiple multivitamins.. Nothing works.. Some doctor told me apthous ulcers from antibiotic side effect and stress factor. But in last december I have a squamous papilloma removal from my left side of tongue.. Which I normally associated with hpv infection. I am concern about these apthous ulcers grown from hpv infection too but all doctors told me that apthous ulcer not associated with hpv... Can hpv cause painless apthous ulcer??
