Hi LanaE,
I would recommend that you arrange a consultation with an Orthodontist, then get an opinion from a 2nd office (perhaps even a 3rd). There really isn't much that one could say from simply looking at pictures of your teeth. An overbite can often be treated with ortho, however a crossbite is usually the result of issues with your palatal structure. Truthfully, your circumstances can only be assessed through an in-office consultation. What I can tell you is that ignoring these conditions will only make the problem (and subsequent treatment) more difficult to fix.
Sorry I couldn't be or more assistance.
Warmest regards,
Dr. Jennifer Thomm
