Abfraction Lesions May Be Toothpaste Abuse

Abfraction Lesions May Be Toothpaste Abuse

Posted by Gabriala Brown on Oct 9th 2018

In 2007, a dentist named Peter E. Dawson wrote a book called “Functional Occlusion, From TMJ to Smile Design".

In that book, Dr. Dawson states “What we have been calling ABFRACTION lesions are really the result of toothpaste abuse”.

Here is a photo of what toothpaste abuse does to teeth and gums:

Toothpaste abuse and the Abfraction Lesion concept was new to me but I learned about it from a periodontist who knows another periodontist who has his pulse on everything dental in the world.

He started a post by saying “I had previously decided not to post on this topic of “Abfractions” because it is highly charged and emotional. Whenever I teach on anything closely related, some audience members can become hostile. But I changed my mind and here goes:

Grippo (JO Grippo. Tooth flexure. J Am Dent Assoc. 1991; 122(7):13.) defines Abfraction is an Enamel and Dentine lesion. Clinically however, most of these lesions, also known as non carious cervical lesions or NCCL’s are cemental in nature, and are almost always associated with facial gingival recession. In other words, inadequate facial bone to support gingival tissue, thin biotype, cemental exposure following gingival recession, and as per Abrahamsen and Jackovitch (excuse the spelling), “TOOTHPASTE ABUSE” and cemental wear. An exception is noted in the cat, which experiences external root resorption and presents with deep cervical lesions sub-gingivally. When NCCL’s are noted occasionally, lingually or palatally, they are ALWAYS associated with recession, misplaced roots lingually, lingual dehiscences and eventually cemental wear from “toothpaste abrasivity”.

Imagine the audience getting angry when they are told that toothpaste abuse is the cause of these so-called abfractions.

For 15 years we’ve been sharing the message about how important it is to use something NON-ABRASIVE because we potentially brush our teeth tens of thousands of times in our life.

Dr. Judd used to warn about toothpaste preventing remineralization but it so happens it’s even worse than that.

The issue with toothpaste used to be about the added glycerin to toothpaste (50-60%) coating teeth and preventing proper remineralization. But pasty oral care is ruining teeth and gums far beyond that. Every time a person brushes with regular toothpaste, they are gently wearing away their teeth and gums and potentially wreaking havoc in the their mouth over time.


Those that are using Tooth Soap® and enjoying it - you truly are doing the best for your teeth and gums.

I’m beyond thrilled to know that for 15 years, I’ve been saving my enamel by brushing with Tooth Soap®. I wish I was using Tooth Soap® since I was a little kid, but I’m happy I have it now. You should be too.
