Dull pressure in gum above tooth and tooth has slightly moved?

20 years old, woke up the other morning with the tooth to the left of my front teeth feeling a bit "weird" had a few shooting pains in my gum when i caught the tooth with my tongue but this subsided within an hour without painkillers. The tooth had also moved slighty back and seems to be pointing inwards, as though its going to underlap my front tooth - it isn't noticeable to the general public but i can see and feel the difference.

I have always had good teeth and general oral health and only had a check up 3 months ago. I went to dentist who did x ray and said nothing wrong, gave me some antibiotics incase of infection and sent me off. im now on my 3rd day on antibiotics, tooth does not appear to have moved any more but now have a weird pressure on above the tooth, almost feels like when you have a new tooth growing through, although obviously this isn't the case, there is no room and it would have shown on x ray.

So im really just very puzzled at what this could be and TERRIFIED the tooth will move more. I have perfect top teeth and it would devistate me to have one messed up :( does anyone have any idea what this could be? i have both top right and top left wisdom teeth coming through, but dentist said enough room and also, none of the other teeth have moved or feel pressured so i assume it cant be the wisdom tooth causing this problem?

any help and advice much appreciated!!
