The gums between my teeth are rounded instead of pointy and make my teeth look smaller. How do i fix this problem? (photos)

It is difficult to tell from your photos exactly what is going on. A visit to your general dentist will put your mind at ease.  There are many causes for the point going away. Your dentist should be able to he you.

I would suggest that you ask your general dentist or your orthodontist for a referral to a periodontist, a gum specialist, who could recontour your gums to make them less bulky and more esthetic.

Hard to tell from the pictures, but the first thing to do is have your gums checked and cleaned.  Calculus or deposits under the gums can blunt your papilla's.
