Can we do scope, CT after dental work?

I have done a wisdom tooth extraction(yesterday) and doing a crown work(root canal done 3 weeks back) next week. I have to see an ENT as well to check for my lower jaw and neck pain. I am planning tos we an ENT after the dental work. My physician want me to check with a neurologist too. Don't know if my jaw, neck pain is because of tmjd or neuralgia or ent issue. I wanted to know if we can do ent procedure like endo scope , ct scan after the dental work. My ent said he wants to do Endo again to check my sinus if it shows any infection. So I want to know if we can do Endo with dental work done and also can we do Endo often ? I had one in June and nothing found. Ent wants to do it again. My dentist said my pain could be from eagle syndrome too. How to diagnose that condition?
