Pearyodontal 

Refers to gum-related issues experienced by arctic explorers.

If Eskimos "live on whale meat and blubber" (You'd cry, too, if you only had whale meat to eat!), I'm surprised that they don't have more Pearyodontal problems.

coitus periodontalis

The act of performing oral sex while having no teeth, or with dentures removed.

After Dennis swallowed the sperm during coitus periodontalis, they pursued the egg by drilling into his gums.
