Welcome to Long Island Dental Hygienists' Association website




The Long Island Dental Hygienists' Association (LIDHA) is the local component of the Dental Hygienists' Association of the State of New York (DHASNY) which, in turn, is a constituent of the American Dental Hygienists' Association (ADHA).

LIDHA is a not for profit organization dedicated to the advancement of dental hygiene. It is the only not for profit dental hygiene association on Long Island that is run by hygienists for hygienists!

The LIDHA board consists of volunteer members who are committed to its members and potential members of Nassau and Suffolk counties. We are a resource for the most up-to-date information from current laws that govern the practice of dental hygiene in NY to the newest products and technology available.

 The Long Island Dental Hygienists’ Association, known as LIDHA, has no affiliation with the Long Island Dental Hygienists’ Forum, known as LIDHF.  We are separate entities with no affiliations.  LIDHA solely represents Long Island Dental Hygienists.  Support us, support your profession.

Statement from the American Dental Hygienists’ Association on Water Fluoridation

In response to the anti-fluoride content that was presented on the Dr. Oz show on February 1, 2016, the American Dental Hygienists' Association is among the more than 125 organizations, including the American Dental Association, American Association of Public Health Dentistry, American Academy of Pediatric Dentistry, and American Academy of Pediatrics, that recognize the public health benefits of water fluoridation, based upon over 70 years of scientific evidence describing the safety and effectiveness of this practice to reduce tooth decay.

According to the U.S. Centers for Disease Control, water fluoridation is among the ten great public health achievements of the 20th century. Drinking fluoridated water reduces tooth decay by 25 percent over a lifetime, and thanks to fluoridated public water systems, nearly 75 percent of Americans from all socioeconomic backgrounds benefit from increased oral health.

As such, the ADHA is a supporter of community water fluoridation as a safe and effective method for reducing the incidence of dental caries, and we continue to promote the education of the public and other health professionals regarding the preventive and therapeutic benefits of fluoride.
