Will i be able to request the dentist to not put the numbing paste stuff on before the novocain (procaine) shot?

Of course!: There is no medical necessity for the topical anesthetic gel. Many people don't like the flavor or the temporary numbness of the throat if they swallow any of it. You can simply have the injection. That is what really numbs the tooth and/or gum for long enough to have the procedure done.

Sure: The topical anesthetic is placed since many patients do not like the needle stick. The injection can be given with or without.

Absolutely: This should be done as a matter of routine. Always ask !

Any request: You should be able to make most any request. Many patients request no anesthetic at all for small, minimally invasive dental work.
