a singer shouldn't make you love yourself, I had a friend with a gap get teased at my school but she never took it and that she would rather keep it, teeth gaps are completely normal I had it when I was younger I get why you would feel this way because everyone sees themselves differently from other peoples perspectives, but I recommend trying to see it on a different prescriptive, and please just be thankful it isn't anything worse. yknow there are many tricks you can do with it :) trust me and did you know many many models have teeth gaps when I say its common it is indeed common
