dr. burhenne here of askthedentist.com. thanks for joining us. so, today, i’m going to talk about fluoride in toothpaste —not in the water, that’s a whole different topic, fluoride in toothpaste —and whether it should be in your toothpaste or whether you should be using it or whether your child should be using it and what if they swallow. those are all good questions. those are questions i get all the time. so, fluoride in toothpaste has some efficacy. it depends on the concentration. toothpaste has fluoride in it, but not at a prescription dose.
you can get that paste from your dentist, and it works better than toothpaste. but here’s the problem. fluoride absorption is best when the tooth is clean, when the biofilm has been reduced or removed or when the pellicle or the skin of the tooth is thinned or off the tooth. and that’s when that covalent bonding, the binding of the fluoride ion is best and glums on to the tooth. and then, it protects your tooth. but the problem is it’s in your toothpaste,
and it’s the toothpaste that is reducing the pellicle. you can’t do it all at the same time. so, what i recommend is that you first use your toothpaste. whether it has fluoride in it or not, it doesn’t matter. and then, pick out an item or get an item like this— in my case, prevident by colgate. these are strong prescription-strength fluoride paste that actually will armor plate, so to speak, your teeth and make them more resistant to tooth decay. so, again fluoride in toothpaste is a little bit of a waste of time.
whether you have it or not, it doesn’t matter. do it right by first brushing. remove the pellicle. make it so that the uptake of fluoride is optimal. and you’re set. you’ll have stronger teeth.
