Protect your enamel
Protect your enamel
Our body has been remarkably designed to have an ability to heal itself. That is one of the most
facinating things about being a health care professional. As a dentist, we cannot do what we do
on our patients without this self healing ability.
However, one area of our body, especially in the mouth (speaking as a dentist), that does not
heal itself is tooth enamel. Enamel is the hardest substance in our body. It constitutes the outer
layers of our teeth not only giving the strength but also providing a sparkling pearly look.
Fortunately, our body is able to remineralize(reharden) enamel from a very minor degree of
loss. However if significant amout of enamel gets lost, the amount of enamel lost will not come
back. It is gone completely. So does the strength of teeth and the aesthetic appearance.
So what are the main causes of enamel loss? To simplify there are two categories. First is
mechanical loss and second is chemical loss. This week, we will talk about one of the
mechanical causes of enamel loss: tooth paste.
Did you know many toothpastes sold over the counter have a high level of abrasiveness? This
abrasiveness actually gives us the “clean” feel after we brush our teeth. However too much of
this will cause significant wear on enemel. When we recommend tooh pastes, we tell our
patients to look out for this abrasive nature of some toothpaste. First, avoid whitening
toothpastes. These tend to have the highest level of abrasiveness. Second look for RDA value of
each tooth paste. RDA refers to the roughness of the toothpastes and is not normally listed in
the packaging. You have to actually call the company. Thankfully I have found a study that
compiles this and posted in our office website and facebook site. If you are interested, please

Next time we will discuss the chemical causes of enamel loss.
