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

Yes.

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

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

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