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

Yes.

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

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

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