Applicants who do not successfully complete the ABCDSM credentialing examination and/or fail to submit satisfactory documentation of completion of supplementary requirements may reapply the following year by submitting a new application, including a copy of their current dental license and application fee. Any missing materials will render the application incomplete and it will be subjected to a late fee.

When reapplying, in terms of supplementary requirements, candidates for Diplomate status in the ABCDSM may use the same letters of recommendation/sponsorship, verification of sleep medicine observation, and patient case summaries. However, only three (3) of the expanded patient case studies from the previous year shall be accepted.
