Do subs affect numbing shots at the dentist

I was at the dentist and i pretty much felt everything even after 6 shots to numb pain at 4 diff times, the first time i went it worked fine when i went back it was like being tortured lol My dentist does know im on subs well i put it down on the report etc Is there a certain kind of anesthesia i need to ask for that subs dont block out?
