Delta Dental Wellness Benefits

Gum disease is associated with a number of systemic conditions, and people with certain chronic conditions may benefit from additional periodontal (gum) cleanings and maintenance. That’s why, in addition to your standard coverage, Delta Dental Wellness Benefits offer expanded coverage (increased frequency and/or coverage level) for those diagnosed with one of the following qualifying medical conditions:

  • Diabetes
  • Heart disease
  • Rheumatoid arthritis
  • Stroke.  

Select the DeltaCare USA or Delta Dental PPO plan below for details on specific wellness benefits.

Eligible participants can receive waived frequency limitations and copayments (D1110, D1120, D4910) when services are needed more frequently due to medical necessity as determined by the Contract Dentist.

Report your medical condition to your dental office, so they can determine if you are eligible for the Wellness Benefit and if extra cleanings are needed to keep your teeth and gums healthy.


Eligible participants can receive:

  • 100% coverage for one periodontal scaling and root planning procedure, per quadrant (D4341 or D4342) every 12 months (versus 24 months)
