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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
Reversal agent: There is now an injection that can be given at the end of an appointment that actually reverses the numbness immediately.

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. ...Read more
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. ...Read more
Novocaine: Is used less frequently today since more effective and less allergenic alternatives such as Lidocaine exist. The "novacaine" has become the generic term for anything that a dentist injects to get you numb. Novocaine is used as an injection form only. ...Read more

In some cases 'sweet air' is used alone or in combination with an injection. ...Read more
Yes Many Factors: Just your anxiety or stress about the root canal can make you "sick". It is rare but possible to be allergic to "novocaine", now usually xylocaine (lidocaine). And if you received a lot of local anesthesia, the more possible. Lastly, if the tooth had a large infection, it is possible the root canal caused a systemic reaction. ...Read more
Fear of injections: First- find a recommended and compassionate dentist. Second-ask to discuss this issue prior to any procedure. Third-trust the dentist as he she has extensive experience and techniques to minimize any discomfort. Fourth- see if your dentist uses "sweet air" as it really gets your mind off the treatment and relaxes you. Patients love it.
