teeth !

Are 'to gring' and 'to gnash' the teeth the same in terms of everyday use in English?

Can you support your argument with common everyday examples, please.

I think you mean 'grind', and there is a slight difference. Grinding the teeh implies that the person may be trying to keep their temper -

Fred was trying to keep calm, I could see he was grinding his teeth."

The second is an old-fashioned expression - hell is said to be full of the sound of 'wailing and gnashing of teeth' - the phrase usually means someone who is grinding their teeth in fury oover something they cannot change - it is not a literal expression, unlike 'grinding'.

Fred was really upset that the horse he bet on lost the race. He was gnashing his teeth when he told me about it."

Hope this helps - re-post if you need more explanation.

Grinding teeth is to move upper and lower teeth against eachother....gnashing teeth is to to make biting movements.
