How To Wear Off Novacaine
Reversal Agent: There are really 2 ways you and your dentist, can control to quicken the length of action of local anesthesia. The first is under your control and that is overall metabolism. If you increase your metabolic rate, the Lidocaine will wear off faster. The second, requires a second injection of a reversal agent called "oraverse". There are others also used, but this is the most popular, currently.
Nothing: Getting the non-feeling of the Novocaine to wear off faster is often unsuccessful. If this is always the case, possibly ask your dentist to use an anesthetic that is designed to wear off faster. Still, each individual may react differently in terms of time for the Novocaine to dissipate.See 3 more doctor answers
Less med or no epi: For certain procedures your dentist may be able to use less medication, or one without a vasoconstrictor, which will allow the anesthetic to wear off faster. Oraverse is a medication your dentist can inject to reverse the effects of the anesthetic, but involves an additional injection and still takes at least an hour to work.See 3 more doctor answers
It varies.: Novocaine is rarely used today. The most common local anesthetic is lidocaine, and the most common formulation is packaged with epinephrine. Lidocaine with Epinephrine will usually provide deep anesthesia to the nerve of a tooth for 45 minutes and for the soft tissue, lips, gums, etc, for twice that. Anesthetic without Epinephrine wears off quicker. Some anesthetics, like marcaine, can last hours.See 2 more doctor answers
Reversal agent: There is now an injection that can be given at the end of an appointment that actually reverses the numbness immediately. It is relatively expensive, and I like the fact that the numbness lingers during the immediate post treatment period. Nsaid administration also insures post injection comfort.See 2 more doctor answers

Short answer, "No": You might have some residual discomfort after the "novocaine" wears off. It might be due to the actual injection and/or the drilling of the tooth, but if there is any discomfort, it should resolve very rapidly. If not, go back to your dentist. Sometimes the bite needs a little refinement, or there are other underlying problems that have to be addressed, especially in deep, extensive fillings.See 1 more doctor answer
Depends.: Novocaine has not been used in the us for many years. Newer, more effective local anesthetics have replaced it. Some last longer than others and where the injection is given matters as well. Lower teeth can stay numb longer. The amount given will also determine duration. In general, numbness will last from 30 minutes to up to 6-8 hours.
As needed: Every person is different, some teeth may need less then a cartridge (1.8ml). Some other teeth more then one, the max depends on the age, the heath and the weight of the patient, some agents are more potent then others. Ultimately it depends on your reaction and to the effect of the anesthetic. Hope this help ease your concerns. Good luck, dr mokbel, scdntalimplants. Com.See 2 more doctor answers
