Hello mam , Lip biting may be due to malposition of your upper front teeth and larger lower lip is also related to that. Your teeth might push your lips outwards to make it look bigger too. Correcting the tooth position by braces can reduce the lip biting. After correcting the teeth the white patch will reduced slowly. Then later stages if you want to correct your lip size it can be corrected . Dr. P. Vidhiyasagar M.D.S.,
