Re: Going to the Dentist but need help!
It depends on each individual tooth that needs treatment. If the decay is just on the surface, enamel only, has not worked it's way down to the soft part of the tooth, then you can get the decay removed and a filling placed without being numb.
If a tooth needs a lot of work on it, and/or the decay is into the soft part of the tooth, it would be recommended to be numb for the procedure.
Since the teeth are already painful and irritated, it would be recommended that you are numb for the procedure.
Have you consulted with your doctor about taking a anti-anxiety medicine before going to the dentist?
You might also want to consult with your dentist about using gas, if available, for you during your dental treatment. If your dentist doesn't use gas, consider going to a dentist who does. The gas will help to relax you and you won't really be concerned about being numb.
