The teeth comment really got to me as well. I have always had terrible teeth, very weak enamel. For a while in my 20s after having abscesses on the front teeth, they became discolored and I was very selfconsciuos, covering my mouth up and not smiling much. Once I could afford it, I had crowns. I have since spent thousands on crowns and even implants (not just for appearance but so I can eat - I think i have one natural tooth left). We’re not affluent, but could manage to pay for it with some considerable sacrifice. If someone had made comments like that to me, I would have been devastated. I was already self conscious enough. Luckily I never ran into anyone that nasty.
