Hello mam, Special care has to be taken for orthodontic treatment . Soft food has to be taken  hard food has to be avoided , food has to be taken in small bites, do not place tongue and check again and again it would cause cuts , during starting of treatment ulcers will be occurring and it is normal . More of plaque and calculus will be seen due to braces proper brushing 2 times a day . Use of mouth wash 2 times a day.

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.

Your orthodontist will give you an instruction booklet regarding the things you can do n that u can't. There is no problem if u touch the braces with your tongue, but be careful not to push it hard. Please rinse and brush your teeth after every meal if possible as there are high chances of food getting stuck in between your teeth
