Clinical dentistry is physically demanding in some very specific ways. Backs, necks, shoulders, wrists and hands that for some reason are vulnerable to injury may be challenged by a combination of position, repetitive motion, stress, and even leisure activities. Some impairments—a fine tremor, for example—would not be disabling for another kind of work, but may prove to be that for a dentist.
Some disabilities are temporary, and others permanent. The challenge for dentists who find themselves in this situation is to look for the possibilities in what may seem to be impossible circumstances. The ADA can help you.
