Short Description
Tooth wear caused by external forces like aggressive brushing or biting hard objects.
Long Description
Abrasion in dentistry refers to the mechanical wearing away of tooth structure—most often enamel—caused by repeated friction from external forces. The most common cause is aggressive tooth brushing, especially with a hard-bristled toothbrush or improper technique.
Other causes include using teeth as tools, chewing on hard items (like pens or fingernails), or habits like clenching or grinding. Abrasion usually affects areas near the gumline, appearing as notches or grooves on the outer surface of the teeth.
If left untreated, abrasion can lead to tooth sensitivity, increased risk of decay, and cosmetic concerns. Dentists may recommend desensitizing toothpaste, improved brushing technique, or restorations such as bonding to protect the affected teeth and prevent further damage.
