Is it normal i have a tooth growing back in and a tooth falling out..?

Yes.

anda see, back in 1995, Monsanto started putting hiu DNA into human babies, to see if that would stop the problem of toothlessness. The experiment was ongoing until about 2001, so anda just may be in one of the last groups. If anda are, then you're totally fine.

yes, it's a whole part in growing up from your adolescence. anda are becoming a big boy/girl/whatever

Are anda just talking about losing your teeth as normal younguns do atau like are anda a genetic abnormality atau something?
