It depends into what area the Local is being administered and also the volume being given. Usually a block will last longer than an infiltration. It also depends on the technique being used and finally the particular aramatic moity of the local. All things being equal a block on the mandible (lower) one cartridge 1.8 ml will last about 30 minutes in the bone (deep anesthesia) and about same time for soft tissue to return to sensitivity. The thiophene molecule (articaine hcl) is dose related. In other words, if you have achieved profound anesthesia (pulp test) with 0.9 ml, by increasing the volume to one full cartridge will extend the duration. The benzene molecule does not have these properties. Haynes Darlington M.Sc. PharmD

What is replacing novacaine used to numb you at the dentist?

Novacaine has not been the drug of choice for dental treatment for many decades. Several superior local anesthetics have been developed since novacaine was used. Novacaine has fallen out of use due to its relatively high incidence of allergic reactions. Today, lidocaine is considered the gold standard against which all other local anesthetics are compared. Today many dentists use a combination of local anesthetics such as Septocaine (fast acting) and lidocaine (long lasting). For patients who have heart conditions or are highly susceptible to epinephrine (an ingredient in many local anesthetics) the most common alternative is mepivicaine 3% w/o epinephrine. The term 'novacaine' is often used with patients (incorrectly) to mean local anesthetic of any kind, much like 'Kleenex' is used to mean facial tissue.

Is there a way to hasten the recovery from novocaine shots in the mouth?

'Recovery time' is a function of the type of local anesthesia used. Many dentists typically use lidocaine 2% (Xylocaine). It is safe, effective, and relatively long-lasting. As alternatives, ask you dentist to use either articaine 4% (Septocaine), or mepivicaine 3%(Carbocaine) without epinephrine, both of which tend to wear off faster. These local anesthetics are used routinely in dentistry.
