The Plan allows one oral examination every six months and two cleanings per calendar year. When services are provided by a Delta Dental PPO dentist, there is no deductible and 100% of the dentist's fee is covered. To help avoid an increased risk of periodontal complications due to hormonal changes, the Plan added an additional oral exam and cleaning for women while they are pregnant. To take advantage of this added benefit, the dentist will need to note on the claim that the patient is pregnant. Individuals receiving post-periodontal surgery maintenance from an in-network dentist are eligible for cleanings and scalings up to four times per year.
