• Rubbing toothpaste and not rinsing afterwards: safe or not?

    From mariomicro@mail.com@21:1/5 to All on Mon Mar 9 19:57:02 2020
    My dentist has prescribed me Duraphat 5000 (5x normal fluoride content). He said that I should:

    1) Brush my teeth with my usual toothpaste.
    2) rinse with water
    3) apply a small amount of Duraphat on my teeth and rub.
    4) don't rinse afterwards.

    However, at the back of the Duraphat box, I read:
    "Do not swallow!"

    Forgive me I'm wrong, but if you don't rinse, you're going to have some toothpaste circulating in your mount and, at one point, you are going to swallow it. Or am I missing something?

    Is the dentist giving me wrong advice? It seems this advice is quite common here in UK:

    It's a matter of degree. I knew Duraphat as a fluoride varnish. I see
    it now comes as a toothpaste, 5000 ppm. As such, it appears to
    Prevident 5000, which I prescribe in my practice. The instructions are
    however to BRUSH with it for 2 minutes, and spit out (not rinsing). The
    idea is to thoroughly expose tooth surfaces and leave a residue that
    will increase resistance to decay. Right off the top of my head, it
    seems you'd get better penetration by brushing, but I don't know this
    for a fact. Also, rubbing on teeth and not rinsing would seem to leave
    more fluoride in the mouth.
    In your linked article, there is no mention of a high-fluoride gel or
    paste. In the U.S., these are available only by prescription. Most
    fluoride toothpastes deliver 0.1% fluoride (1000 ppm.) So your
    high-fluoride paste is 5 times as concentrated.
    I would be inclined to urge caution--if you're going to do this, use a
    very small amount to rub into your teeth.
