Wisdom tooth extraction prior to braces? (in my 40's). (photo)

Orthodontist suggested I have the lower wisdom tooth extracted before considering Damon braces. This tooth causes facial pain on occasion. How long after extraction should I wait to get braces? How do I find an oral surgeon with experience removing wisdom tooth so close to the lower nerve? I am nervous about permanent numbness. The top two wisdom teeth are asymptomatic- should I have them removed as well or "let sleeping dogs lie"?
