Before and after the most ungodly of your godly matrimonial obligations, rinse your mouth out with a half-dilution of room temperature Clorox bleach. Not only will this kill germs and prepare you for the vile taste that awaits once your hubby begins invoking the name of the Lord as you busily bob below -- you will thank me when you see the glorious effects that a potent wallop of household bleach has on your yellow smoker's teeth! Praise the Lord!
