Hello,I'm Dima, 22. I was born with one lung and my heart was shifted to the right. I live a normal life and take no medication. However ever since I was born when I open my mouth a bit more, especially when pronouncing vowels or smiling my lower mouth lip tends to go to the right. It is as if there is something missing on the left side stopping my lower lip to be straight. I haven't asked anyone before. Can you advice me? Thanks
