How does a tongue piercing affect you?

if your tongue is between your front teeth when you suck it, you get an open bite. your front teeth can also stick out. i suck my tongue too but instead of it between my teeth, i fold my tongue in half and then suck it. that caused me to have an overbite because somehow in folding my tongue and sucking it, it caused my lower jaw to go in hence my overbite.
