My dental isn't valid/effective until next month. Can I still see a dentist right now and have them "charge" them next month?

Sooo my dental will be effective on 7/1/2015. Could I go to the dentist today, get work done and have them bill the insurance on 7/1/2015? I heard from a friend that you can pay cash and once your insurance goes through, some places will refund your cash payment and bill the insurance?
