Receding Gums vs. Toothbrush Abrasion
Receding gums and toothbrush abrasion both expose more tooth surface, but one is driven by inflammation and bone loss while the other is mechanical wear from aggressive brushing.
Key Facts
- True gum recession involves loss of attachment and often underlying bone
- Toothbrush abrasion is mechanical and most visible at the gumline notch
- Hard-bristle brushes and horizontal scrubbing are the top causes of abrasion
- Both conditions increase root sensitivity and decay risk
What Is Gum Recession?
Gum recession is the apical migration of the gingival margin caused by periodontitis, occlusal trauma, thin biotype, or orthodontic movement. The exposed root surface is more prone to sensitivity, root caries, and plaque retention.
What Is Toothbrush Abrasion?
Toothbrush abrasion is a wedge-shaped notch at the cervical area of the tooth created by repeated horizontal scrubbing with a hard or stiff brush, often paired with abrasive toothpaste.
How They Overlap
Both expose the root, both cause sensitivity, and both can coexist. Aggressive brushing can also actively push the gum margin downward, accelerating real recession.
