This is exceedingly rare. The chances of it happening are very slim.. Going to the dentist causes anxiety for many including you.

We are aiming for around the nerve area (see picture), we very rarely touch the actual nerve. If we do, you may feel a shock for a second but don't worry it generally doesn't do permanent damage to the nerve. There is usually a dentist supervising the students as well if they are new.

There are external landmarks that are used to determine where to give an injection. Since dentists don't have xray vision there is always a possibility that a nerve is hit. The chances are about 1 in 1, 000, 000. Even if this does happen there is usually no permanent damage. Besides the students practice on each first.

Even the best dentists may accidentally hit a nerve area while injecting. The anatomy on some patients may be a bit different than others, but usually the landmarks are there to avoid problems. If you have doubts with the student, ask to have the staff dr. Be there to personally supervise.

That's what those 10,000 hours of Dental Schoolare all about.After classroom and laboratory training, the student Dentist will then provide care for you under the supervision of an Attending, an experienced licensed Dentist.
