7 Certificate Programs Dental Hygienists Should Consider in 2025

As dentistry and medicine work toward better integration, Registered Dental Hygienists (RDHs) continue to be instrumental in the shifts that are occurring. As the prevention specialists of dentistry, some further their education beyond licensure, securing a Master’s or Doctorate degree. For some, however, it is not feasible due to time, family demands, or finances. Certificate programs build on the education an RDH already has, training them for expanded roles and career opportunities at a fraction of the time and cost.

The idea of specialization in the field of dental hygiene is not new. We already have hygienists who specialize in periodontics, cosmetic dentistry, and pediatrics. They learn specialty information on the job from fellow dental providers, or are tasked with piecing together continuing education that fits their specialty needs via internet search.

Unfortunately, it's rare to find continuing education that is specific to the practice of dental hygiene, but these certificate programs demonstrate that an RDH has met specific industry standards and possesses recognized expertise.
