DENTAL INJECTIONS

What is a dental injection ?

Dental injection contains local anesthetic. Patients usually receive one at dental offices prior to some dental procedures. Local anesthetic causes loss of a pain at the site where it was administered. With its help, any interventions in dentistry are performed painlessly.

How dental injection works?

Body recognises local anesthetic as a foreign substance, so it is trying to remove it as soon as possible, by increasing the blood flow in this area, so insensitivity does not hold for very long. To this end, they were starting to add adrenaline into a local anesthetics, which can prolong an anesthetic effect in the tissues. Adrenaline is added to an anesthetic in a very small amount, which still has the beneficial effects, while its side effects are minimized. Adrenaline is known vasoconstrictor, which means that it contracts blood vessels. This means that anesthetic solution spreads from the site of introduction in the body very slowly. Thus, the possibility of overdosing is reduced. Blood flow is slowed down so anesthetic longer stays at the injection site and works just around the dental nerve, where we want. The patient has no pain during and for several hours afterwards. Anesthetic reduces bleeding in the areas of administration, which facilitates dental procedures. Local anesthetics without adrenaline can be used in patients with certain cardiovascular diseases, or there can be used smaller amount of anesthetic with adrenaline.
