Hi, after putting braces if you will regularly touch then with your tongue it will lead to tongue cuts/ulcers, don't do that. To take care of braces, please eat all soft or semisolid food, don't bite on anything with your front teeth, eat slowly, have small bites of food, buy an Ortho brush which would help u maintain good oral hygiene and use mouthwash daily to avoid bad odour from mouth.

Consult your Orthodontist anytime you have some difficulty.
