Dr. Koshki is often asked this question. We turn to our friends at Delta Dental to help us answer:
Watch out for too much of a good thing!
Brushing regularly is considered vital for healthy teeth and gums, but dental experts warn that you can overdo a good thing. Known as “toothbrush abrasion,” over brushing can lead to sensitive teeth and receding gums.
Vigorous brushing can wear down the enamel on the teeth as well as damage and push back the gums, exposing the sensitive root area. Receding gums can also lead to other dental problems such as periodontal disease and cavities on the roots of the teeth and may lead to the need for treatments such as fillings, root canals and tooth extraction. According to the Wall Street Journal, dentists estimate that between 10 to 20 percent of the population have damaged their teeth or gums as a result of over brushing.
The people most at risk for tooth or gum damage from over brushing are those who are particularly diligent about their oral care and those who use medium- or hard-bristled toothbrushes. Other factors, such as a genetic predisposition to receding gums, clenching or grinding your teeth or having had your teeth straightened with braces, can increase your risk for damage from over brushing.
Brushing vigorously isn’t necessary to remove plaque. “Plaque is so soft that you could remove it with a rag if you could reach all the surfaces where it hides,” says Dr. Kevin Sheu, managing dental consultant for Delta Dental. “Thoroughness is what is required for plaque removal, not aggressive brushing. You’re not going to achieve any extra benefit by brushing hard.”
Changing brushing habits can usually stop the problem from getting worse. In cases of severe toothbrush abrasion, Dr. Koshki can fill in the grooves with bonding material.
Dr. Koshki and his hygienists recommend soft bristle toothbrushes, or better yet, use a DiamondClean by Philips Sonicare for the most thorough yet gentle teeth cleaning action available.
