Cavities

I'll be like candy
Rotting your teeth
With sweet smiles
A sugary knife in the sheath

I'll rot your teeth
Expose your gums
Make you obsessed
And play your heart to the drums

Music you sing
It's getting boring
I want to move one
And leave your eyes pouring

Soon enough, I'll leave
And start the cycle anew
But there's no need to cry
No need to turn feel blue

I'll give them the same treatment
And leave cavities in their teeth

Well done so far @NiMiKota - if you're trying to post in publishing center by the way for reviews you just click that "publishing center" button on the top bar of the site - but if you're doing NaPo good luck with that as well! You've got some nice rhymes going on in this one above - with quite an unpleasant subject!
