Why rough edges form on teeth as you age

Teeth naturally develop small rough or jagged edges over time due to everyday wear and tear. Dr Sharmishtha Lad, a dentist and healthcare entrepreneur, shared insights on the habits and causes behind these changes.

Causes of Wear

Teeth grinding and clenching place extra pressure on teeth, gradually altering their shape and edges. Biting on hard objects like ice, pens, nails, or bottle caps also causes small chips or rough spots through sudden pressure. Meanwhile, acidic foods and drinks temporarily soften the enamel, making the tooth surface more vulnerable to damage from grinding or biting habits.

Brushing and Bite

Repeatedly brushing with excessive pressure contributes to enamel wear, especially when combined with other daily factors. Additionally, how the upper and lower teeth meet can cause certain areas to experience heavier pressure and wear than usual.

When to See a Dentist

Not every rough edge requires medical attention, but new, sharp, or increasingly noticeable changes should be examined by a professional. Dentists can check if the change is normal wear or an underlying issue, and people should avoid trying to smooth rough edges themselves.

Context

Enamel is the hard outer surface that protects teeth, but it can wear down over the years from physical stress and chemical exposure. Routine dental check-ups help monitor these gradual changes and prevent further damage to oral health.
