relationship between these abnormalities and mental disabilities....here in the USA mental disorders (your wording disabilities) have nothing to do with birth defects (ie bones and teeth formations)

that said of course a person who may have physical challenges like birth defects like how their bones and teeth are shaped/developed, may not have a good self esteem /self worth and can cause them to feel sad, self conscious...

that said what you posted can be fixed. a dentist can fix your teeth, there are many different things like braces, caps, crowns,, dentures, that can improve someones teeth, underbites, overbites and much more. double whorls can also be fixed by wearing different hair styles, wigs, or using styling with longer hair styles,

I know many who have gone to the dentist and got their teeth fixed and have "trained" their hair to go in a style that they like even though they have single double and triple whorls.

my suggestion set up an appointment with a dentist and tell them your problem and they will tell you how they can help you fix these things with you.
