What is the patch? | Dental Treatment Guide

The United States Food and Drug Administration approved an anaesthetic patch that can be used in dentistry in the year nineteen ninety six. It is a small patch that looks like an adhesive strip. The patch has lidocaine and it is placed in the mouth for about fifteen minutes. The anaesthesia will take about two to five minutes to work and it will last for about thirty minutes after the patch has been removed.

The patch works like lidocain ointment. In fact, sometimes it may even work better and safer because it produces lower levels of anaesthetic in the blood. The levels are at around eleven percent of lidocain compared to injections and around fifty percent compared to ointments.
