Could I get bonding done if teeth aren't perfectly straight?

Hi, thanks for the question... You could get composite veneers, but is good to evaluate your bite, because couldn't work anything you put in there if your bite is to aggressive, send pictures to having a better idea. Regards 

Small changes can usually be fixed by polishing or contouring the teeth.  Bite forces create stress that bonding normally cannot tolerate, so porcelain is better.  However, porcelain is not bulletproof.  This sounds more complicated than you are aware, so be sure to seek and experienced cosmetic dentist or a prosthodontist.  Orthodontics is likely the best and CHEAPEST solution.

Thank you for asking your question.  Sometimes small improvements in esthetics can be acheived with bonding alone. However, if too small then the bonding can come off.  If your crossbite interferes with where the bonding is being placed then the crossbite should be corrected first.  Your case would have to be fully evaluated to give you a proper assessment.
