As part of toothache sprays, a substance called lidocaine is currently used in dentistry. This component is a local anesthetic. The effect of it lasts from thirty to seventy minutes.

Structure
As already mentioned, the active ingredient in sprays for toothache is lidocaine. This substance is from the amide series, producing a pronounced membrane stabilizing effect, blocking the conduction of impulses along the nerve fiber. The best absorption and assimilation of the active component is facilitated by additional ingredients in the form of propylene glycol, ethyl alcohol and peppermint leaf oil.
Mechanism of action
Experts note the effectiveness of lidocaine-based toothache sprays. The mechanism of their influence in this case is quite simple:

- The presence of budgetary variations of the drug, for example, a solution in ampoules is available in an affordable price range, so absolutely anyone can buy it.
The solution, which is sold in carps, can be used by specialists in the treatment of teeth. This form facilitates the process of anesthesia for dentists, and thin needles do not cause additional pain to the patient during administration.
A spray for toothache with lidocaine is very convenient to use for a one-time elimination of acute pain during treatment.
