 My entire family, we've been using it for over 20 years, and so are my colleagues. We don't want tooth decay. We don't want gingivitis. We don't want periodontal disease because they're linked to other health problems like heart disease. And if you get as uptight as I do about getting bad news over at your dental provider's office, then you're going to do what I do, and that's the SPRY, S-P-R-Y, Dental Defense System.
