June 2023 Update

As you may have heard, the Colorado Dental Association had their House of Delegates on June 8-10, 2023. Much of the discussion revolved around the workforce shortages and struggles that dentists are having in hiring dental hygienists.

The CDA House of Delegates overwhelmingly passed resolution #32-23 with a 72-17 vote. The resolution states that CDA will develop and submit a Sunrise Review application to expand the dental assistant scope of practice by December 2023 that should include scope, supervision, training, and any licensing requirements to allow for dental assistants to do periodontal probing and calculus removal under direct supervision of a dentist.
