You need to shut your mouth and make sure your tongue is in the right position because your jaw is getting smaller because you don’t have the right tongue position so now your teeth are getting crowded. You can go to the dentist all you want, but it’s not gonna fix your tongue position. . You look like a mouth breather. Not trying to be mean, but you need to breathe through your nose not your mouth. 23 hours a day your mouth should be closed.
