Over 20 percent of the U.S. population has a disability. These disabilities can be present at birth and last throughout life or they can develop later in life. Disabilities can range from mild to severe and may affect the mind or the body or both. People with disabilities usually have more dental problems than those who do not have a disability. Some people with disabilities need no help with brushing or flossing. Others may need just a little help. Some may depend completely on others to provide their dental care. It is very important to look at the person's specific needs to help find what works best for their dental care.
