What over-the-counter medication can i use to numb my whole mouth. especially my tongue? orajel, orasol, and benzocaine doesn't do the job.

See your dentist: The medications you mentioned are the few you can buy without a prescription. If you are having mouth pain you should see your dentist for advice.

None: The medications you listed have specific and localized uses. They are intended for short-term mild relief of symptoms to 'bridge' you until you can be seen by a dentist. Usually lasting between 10-20 minutes. Seek treatment asap if the symptoms which you are experiencing are, in fact, causing tooth, gum, and tongue pain!

Nothing: Nothing will numb your whole mouth. What reason could you possibly have to want to numb your whole mouth. Doesn't seem logical.
