The inherent fear many of us have of dental treatment may be exaggerated, says Dr. Avi Eyal.

In dental schools, the future doctors are taught what to do in these cases. Some people are sensitive to adrenaline, which is found in the numbing agent. It is always important to verify these sensitivities before treatment and to use alternative materials. Additional stressful cases may happen due to carelessness on the part of the attending physician, Dr. Eyal says. The cases described here have happened in the past and are likely to happen in the future, but they are rare.
