My lower jaw is not aligned with upper jaw and I may require mandibular expander for correction. Please help me to connect with orthodontist in Agra or in nearby cities that uses expander treatment for their patient. I already visited 4-5 orthodontist in agra but 2 out of them claim that expander uses for only upper jaw and not for lower jaw (is it true?) and rest doesn't use expander procedure as they say it's typical and not always work.
