What may aggressive toothbrushing cause?

Aggressive toothbrushing can lead to abrasion, which refers to the wearing away of the tooth surface, particularly the enamel and possibly parts of the cementum at the root surface. When a person brushes their teeth too vigorously or uses a hard-bristled toothbrush, this excessive force can scrub away the delicate protective layers of the teeth. This not only can lead to visible wear of the tooth structure but may also result in a smoother enamel surface, which paradoxically may increase susceptibility to plaque accumulation and stains.

The development of abrasion often manifests as notches or grooves near the gumline, and over time, it can expose the underlying dentin, leading to further complications. Caring for teeth with gentle and proper brushing techniques, using a soft-bristled toothbrush, and focusing on thorough cleaning without excessive force can help prevent this condition. Understanding the balance in brushing dynamics is crucial for maintaining oral health and the structural integrity of teeth.
