How Local Anesthetics Work In Dental Procedures
There Usually Have No Side Effects Or Allergy Reactions
Dental procedures are painful, therefore, the dentist must apply a substance to suppress the pain signals that travel through the nerves, which is called anesthesia. The most common form is local anesthesia which suppresses pain in a certain area of the mouth during a dental procedure. It is not like general anesthesia, which is used for surgery, requires specialists, and sleeps the patient. There are two types of local anesthetics. One of them is topical, which is applied like a spray and numbs the surface of the gums before applying the injectable anesthetic, which blocks nerve endings and dulls the mouth tissues. The local injectable anesthetic is usually lidocaine and contains a vasoconstrictor to extend the effect by narrowing the blood vessels in the anesthetized area. There are normally no side effects nor allergic reactions. However, the vasoconstrictor might increase the heartbeat for some minutes. Additional info click here.
