Hi, I recently visited a dentist and without an x-ray and after 2 minutes examination she told me that I needed 4 premolars extractions as well as the wisdom teeth in order to get braces. My question is: is an extraction of so many teeth is really needed in my case? What are my options and my next step? what type of clear/invisible braces would work on me? and also what would the right procedure be in my case? Many thanks
