Question by The bohemian: what would cause a persons teeth to become so messed up, decayed like?
theres this dude i work with and his teeth look like it literally just decayed right off. you can see 1 visible tooth when you see him talk. we were talking about it at work and we’re suspecting he does meth. he never eats, sometimes in a good mood and usually has fits of anger. the dude gives me the creeps

I would say he could do meth,but my brother was on meth and he was “thick”,had amazing teeth and ate like a horse!!You see some people have problems with their teeth,like me.I am only 13 but when I was younger,I had horrible brushing habits and now I am having to get 7 teeth pulled!It could also be hereditary,having bad teeth.So I would keep an eye on him because he could just have bad teeth and he never eats because it hurts him to eat,so he just eats at home(like me).He is in a good mood because maybe he just has to be brave and put on an “act”because he knows that others know about his teeth.For the fits of anger he could have ADD,or ADHD,ever thought of that??Look Im not saying he is not on meth,Im just saying you dont know for sure if he is or not!

if he is doing meth you should be able to see it in his eyes. pay close attention to them…are they wild? have trouble focusing? dilated? He could be a methhead, or he could just have bad teeth…he might not eat at work because of the pain of his teeth being so bad…I still lean toward meth though, because getting a tooth pulled is not that expensive and it sounds like he has had NO dental care…and meth heads are creepy by nature
