So, what do you think? 45? 50? 60? Can't tell? My teeth won't give me away. If they are my real teeth, I think I'd let you get this close if they were dentures. Maybe if I used Effordent, then there would be no stains or denture odor to worry about. So what do you say? Not sure? Well, you could ask my wife. Or is she my daughter? So effervescent. So effective. Your secret is safe with Effordent.
