Gum Bump

[ollie1178]

Hi All, I had my wisdom teeth out around 4 years ago. Shortly after I noticed a bump...looks like gum tissue but harder...at the extraction site but right up against my last molar. It doesn't hurt when you touch it or brush it, but it does occasionally become irritated. I've had cleanings and such since and no one has ever commented on it. It's becoming more of irritating as I can't stop touching it. Could this just be the way my gums and jawbone healed or do you think it's something more? That side did have some complications during the removal (oral surgeon said he had to shave more bone than anticipated). I do have a dentist appointment on Monday and will ask then. Just looking for suggestions.
