Toothbrush Abrasion? Probably Not.


Abfraction lesions are small notches caused by stress (forces) on your teeth. Biting, chewing, clenching and grinding put pressure on your teeth. Over time, this pressure can cause cracks and splits in the outer layer of your teeth. This occurs in the thinnest part of your enamel, near the gumline. This weakens the tooth and also causes sensitivity by exposing the layer under the enamel.

We used to think these notches near the gumline were “toothbrush abrasion” and many patients still believe this but newer evidence points to misalignment of teeth as the cause. Teeth that are not in their correct position suffer undue stresses which lead to abfractions.

Straightening your teeth is no longer considered a beauty treatment. We now know that correctly aligned teeth are easier to keep clean which can help prevent gum disease. With the link between gum disease and other chronic diseases such as heart disease it is important to keep your teeth and gums healthy for your overall health. Correctly aligned teeth also do not suffer undue stress which can lead to abfractions. More and more adults are getting their teeth straightened for health reasons. Invisalign is a great option for those who do not want all of the metal in their mouth. You can remove Invisalign to eat and to brush and floss.

Here at Cosmetic Dentistry of San Antonio, Dr. Edward J Camacho has done hundreds of Invisalign cases and has been recognized by other Invisalign providers as an outstanding Invisalign clinician. We have patients of all ages in Invisalign including patients in their late 60’s. Statistics show that people who keep their teeth live an average of 7-10 years longer than those who are edentulous. Having your own teeth also allows you to enjoy your food and smile freely without worries. These things significantly increase the quality of your life no matter what your age is.
