Gum covering part of lower back tooth?!

Gum covering part of lower back tooth?

I don't know how long this has been an issue (at least the past few months) but I'm a 19 year old male and have noticed part of my lower-left back tooth is partly covered.

Feeling with my finger, running it along my bottom left row of teeth, when I get to the last tooth, half way through their is gum and when I move over and across to the inside of the tooth, gum covers it.

The problem here is that is I eat a lot using the lower left teeth then it feels sore aftwards, although this is only noticable when I push down on it using my tongue or finger.

First off, is this something to worry about and can I be advised on what could be done about it? I really don't like the idea of having it operated on, but obviously don't want to neglect it and end up with something worse.

Thanks in advance for any help.

It sounds like a partialy impacted wisdom tooth, and you can leave it if it doesnt cause you pain. But there are a few things you should do, buy a water pick, so that you can cleans the tooth properly and get all the junk out from under ther gum line. Also make sure you see a dentist every 6 months for a routine cleaning. I have the same problem and after buying the water pick My gums didnt have any soreness anymore after eating.
