About the American Board of Dental Sleep Medicine

The American Board of Dental Sleep Medicine (ABDSM) is an independent board of examiners that was established in 2004 for duly licensed dentists who treat sleep related breathing disorders. The ABDSM evolved from and replaced the Certification Program of the American Academy of Dental Sleep Medicine (AADSM) (formerly called the Sleep Disorders Dental Society [SDDS]), which had been established in 1998.

The purpose of the ABDSM is to provide a certification regarding the scope of dental sleep medicine, which includes oral appliances and upper airway surgery to treat sleep related breathing disorders such as snoring and obstructive sleep apnea (OSA), and to assure professional dental and medical colleagues, patients, and the public of an acceptable level of education, training, and experience by those who become Diplomates of the ABDSM by examination. It does not represent a new specialty of dentistry or medicine, nor does it grant or imply any legal qualification, privilege or license to practice. Rather, it recognizes those dentists duly licensed by law who have successfully completed the board-certification requirements established by the ABDSM. The American Academy of Sleep Medicine (AASM) recognizes Diplomate status granted by the ABDSM.

Board certification by the ABDSM is open to qualified applicants who are permanent residents of the United States (territories) and Canada. International applicants who are not permanent residents of these countries are NOT eligible to attain ABDSM Diplomate status. For those individuals, International Certificate status is available.

Prerequisite qualifications to sit for the examination include a valid dental license, continuing education hours in dental sleep medicine or sleep medicine, letters of recommendation from sleep physicians, and observation hours at a sleep center. Currently, there are more than 325 Diplomates of the ABDSM.
