Hi! I recently noticed this pretty intense bump on my gum, which I hadn’t noticed before, and I was wondering what it was and if I should schedule and appointment ASAP or just wait to bring it up at my next check-up. Sorry about the yellow teeth in the photos :-(

Info about it: I only noticed it yesterday, so I don’t know how long I’ve had it. However I was at the dentist at the end of December and they hadn’t mentioned anything, so it probably showed up afterwards. I don’t drink, smoke, or take any medication. I wear nightly retainers (I’m wearing the top half in the image, I also wear bottom ones but took them off for the pictures). I brush and floss regularly. At my last dentist appointment, they alerted me to a spot on the tooth that this bump is under that they said could develop into a cavity and said I should take extra care brushing and flossing, which I have. I’m pretty sure the tooth number is #19. The bump is firm and hard but the skin around it isn’t taut, and it also doesn’t hurt at all, even when I press it. It doesn’t obstruct anything or cause discomfort.

  
Does anybody have any idea what this could be, and should I seek out an appointment with a dentist before the one I have scheduled in June? Thanks!

Does this bump on my gum require immediate action?
