What is the best toothpaste?

July 15, 2013
How do you clean a bathtub? Normally, you use a hard brush, plenty of elbow grease and a lot of abrasive cleaner. However, that is not how you want to clean your teeth unless you want to wear them away. We discussed the type of tooth brush to use (soft) in our first post and how much force you should use when brushing in our second post.

Why toothpaste matters

This post deals with the type of toothpaste (abrasive cleaner) you use and how much. I used to think the type of toothpaste or how much didn’t matter, but after years of observation and research, I now think it matters. I have come to the conclusion that the abrasiveness of toothpaste can effect the rate of gum recession and tooth structure loss. The abrasiveness of a toothpaste is especially important if you already have recession exposing the softer part of the tooth.

Which tooth paste is best?

Some studies question whether we need to use toothpaste at all. In many studies, dry brushing without paste has been shown more effective at removing bacteria than brushing with toothpaste. So, why do we use toothpaste? It makes our mouths taste better, which, of course, is great marketing by toothpaste companies. So, aren’t all toothpastes pretty much the same? According to each manufacturer, their toothpaste is unique and the best. Our main concern in this blog is the abrasiveness of different tooth pastes and the effect this could have on recession. As you can see from the attached table, the abrasiveness of toothpastes varies widely from 40 to 200. The exact number means little, but a comparison gives us good information. Look your tooth paste up and see where it falls on the scale. My suggestion would be to avoid the highly abrasive toothpastes especially if you have recession or wear. Perhaps, I am being overcautiuos as the American Dental Association sets an upper limit on toothpaste abrasiveness at 250, but it never hurts to be informed. I find it interesting that many of the “whitening” tooth pastes are the most abrasive. The patients who buy these are concerned with their oral hygiene and prone to overzealous brushing to begin with and often unaware that as they wear away their enamel their teeth actually get darker not lighter. They also often present with significant recession.

How much toothpaste should I use?

TOOTH PASTE COMPANY IDEAL

Tooth paste company ideal

Of course, toothpaste companies want you to use as much paste as possible. They want to sell toothpaste. The classic picture of the toothpaste completely covering the head of the toothbrush is overkill.

Ideal amount of toothpaste

In reality, the toothpaste only needs to be a small amount especially if the major benefit is simply to freshen our mouth. The additional paste is just additional abrasive cleaner and does little to help clean the bacteria off our teeth. The extra abrasive can also result in increased tooth structure loss and recession. Excess toothpaste also produces excess foam and the need to spit, creating a mess. As an aside,the foam producing compound sodium laryl sulfate has been linked to canker sores, so if you are prone to them, avoid toothpastes containing it.

At this point I am not going to get into the controversy about fluoride, I will save that for a later blog. I will simply say I believe fluoride has health benefits for your teeth and that my family uses fluoride containing toothpastes to protect and strengthen our teeth. The paste does make our mouth taste cleaner but has very little additional cleaning benefit except the fluoride. The fluoride in tooth paste is antibacterial and remineralizes your teeth. You could get the same effect by simply using a fluoride mouth wash. Perhaps, someone with no recession or roots exposed can use any toothpaste they want, but when I see a patient who already has recession, I do think it matters because the soft part of the tooth, the root is exposed.
