I believe I have a mouth infection (part of my cheek and gum on one side of my mouth has turned white and there is bump under my jawline), it’s really painful but I get the occasional twinge and can feel it. I know that it needs to be treated but I’m not currently registered with any dentist as I only recently moved to my area so would any dentists treat me/give me an emergency appointment? If I rang around my local dentists, would they be able to prescribe antibiotics over the phone (I read an article about it on the BBC)?
