Health through Oral Wellness® is now available to subscribers and their dependents in more than 8,600 of DDOK’s fully-insured groups. Members with access to HOW® may receive the approved assessment to determine if they are at higher risk for developing caries and/or periodontal disease.

DDOK members who are eligible for HOW® enhanced benefits and receive qualifying score(s) on the assessment will receive additional preventive benefits to help them achieve optimal oral health. The approved clinical risk assessment associated with HOW® must be administered in a dentist office.

PreViser® is the approved clinical risk assessment attributed to HOW. This tool is available to your practice and HOW® assessments can be conducted on DDOK members, at no cost to you. Please select the link below to complete your PreViser registration.

*Note: a separate registration is required for each practice location.
