please help! what is the difference between a cross bite and an open bite?

How teeth contact: Normally upper teeth are offset towards the buccal (cheek side) so they slightly overlap the lower teeth placing the buccal cusps of lower teeth in the center of upper teeth and the lingual cusps (tongue side) of upper teeth are in center of lower teeth. Any other position is considered some kind of cross bite. An open bite is when teeth do not touch each other.

Plane of space: Horizontal crossbite refers to side-to-side malrelationship. Sagittal crossbite refers to front-t0-back malrelationship. Open bite refers to failure of front teeth to meet vertically. Souynds like you should see a qualified orthodontic specialist for an examination (often complimentary) and discussion of your malocclusion.

Crossbite vs Open: Crossbite is when one or more of the upper teeth biting on the inside of the lower teeth. Open bite is when there is a vertical space between the occlusal surfaces of the upper and lower teeth. Hope it helps.
