Hello. Get a thorough Dental examination done. Your Dentist will suggest you few X-ray images and evaluate clinically and suggest treatment options. Depending on the extent and whether the malalignment is due to dental factors or skeletal (bone factor), either an Orthodontic treatment (braces/aligners) or Orthognathic treatment (braces+ jaw surgery) might be required.

You would require braces or clear aligners. Surgery may be needed if its skeletal crossbite. You would be evaluated by an orthodontist. Depending on the type of appliance, the cost would vary. A maximum of 1.5 to 2 years would be necessary

Normally Crossbite can be corrected through Orthodontic treatment through braces. You have to undergo treatment from one year to one and half years. Charges vary from 25k and above according to the material of brackets and Dentist.
