Red spot on gums

[Harry]

Hi, I am 16 a week or so ago I felt this bump on the back of my tooth. I didn't think that much if it. Today I felt it again so I decided to try to take a picture of it.
It feels quite big but it seems to be quite small? And it is red i can't get a good picture but this is it.
It doesn't hurt at all.
I am really worried it is a tomour

Toothbrush irritation, from improper brushing, causes receding gums, worn enamel, red spots and tooth sensitivity. I think this is not a tomour. You have not to worry.
