Hi. It is difficult to assess without looking at your pictures, but trust your orthodontist to give you the correct treatment. About your jaw appearance due to clenching, Botox will help you immensely to get it back to normal. It's easy, safe and a quick painless process. Visit an Oral Surgeon for the same. Good Luck and best wishes for your treatment, Best Regards.
