Tooth Abrasion

Tooth abrasion is wear of tooth material caused by friction, most often from brushing too hard, using a hard toothbrush, or brushing with an abrasive product. It differs from erosion, which is chemical wear from acids, and from decay, which is bacterial damage. Abrasion often shows as a notch or groove near the gum line, especially on teeth that are brushed with a horizontal scrubbing motion.

What Tooth Abrasion involves

A dentist will check the pattern of wear, whether the root is exposed, and what habit is causing it. Care focuses on changing the brushing technique, protecting the worn area, and repairing it if sensitivity or decay develops. Abrasion is managed over time, because the worn tooth material does not grow back.

Signs of Tooth Abrasion

• A notch or groove near the gum line
• Sensitivity to cold or to brushing in that area
• Teeth that look worn on one side
• A tooth that feels sensitive after brushing

What to do right away for Tooth Abrasion

• Switch to a soft toothbrush and gentle, circular brushing
• Avoid scrubbing back and forth with force at the gum line
• Wait after acidic foods before brushing
• Call for help if sensitivity is severe, a notch deepens, or pain develops

How a dentist may help with Tooth Abrasion

• Examine the pattern of wear and check for root exposure
• Identify the brushing habit or product contributing to wear
• Protect the worn area with a suitable treatment
• Give guidance on brush type, technique, and toothpaste
