I've been ill for about 3 weeks with the flu. Now I'm at the tail end of it, I have a really sore patch on the roof of my mouth next to my back molar (maybe wisdom tooth??). Is this what an abcess feels like? It's puffy, incredibly sensitive and I'm terrified to go to the dentist anyway, let alone if I need to be punctured. I had one when I was bout 11 and I can't remember what it felt like, but I do remember having it lanced was horrific. What can I do that ISN'T go to a dentist?
