What Is Attrition? The Tooth Wear From Teeth Grinding and Clenching

Your teeth are flat, short, or worn down at the edges. That could be attrition — wear from habitual grinding or clenching. It's common, often happens at night, and most people don't know they're doing it.

Your teeth are flat, short, or worn down at the edges. That could be attrition — wear from habitual grinding or clenching. It's common, often happens at night, and most people don't know they're doing it.

Attrition is tooth-to-tooth wear. When you grind or clench, your upper and lower teeth rub against each other. Over time, this flattens the chewing surfaces, shortens the teeth, and rounds the edges. It's a slow process — but it never stops unless you address it.


Why Does It Happen?

Stress is a major factor. Many people clench or grind when they're anxious, concentrating, or asleep. Misaligned teeth can also contribute — if your bite doesn't come together evenly, some teeth take more force than others. Sleep apnoea is also linked to grinding. Some people grind their teeth as a habit, day or night. Many do it entirely unconsciously.


What Are the Signs?

Your dentist may spot it before you do. Look for teeth that appear flat, especially on the molars. Your front teeth may look shorter or have worn edges. You might notice a clicking jaw, sore muscles in the morning, headaches upon waking, or a feeling that your teeth don't fit together the way they used to. Your partner might even hear you grinding at night.


What Damage Does It Cause?

Beyond worn teeth, attrition puts enormous stress on your jaw joint (TMJ). It can cause muscle pain, joint pain, and headaches. Teeth can crack, chip, or become loose. The loss of tooth height changes your bite and can make your face look older. Your enamel wears thin, exposing dentine, which leads to sensitivity.


How Is It Treated?

A night guard is the most common treatment. It's a custom-fitted appliance you wear while you sleep. It doesn't stop you from grinding, but it absorbs the force and protects your teeth. Your dentist may also recommend stress management, muscle relaxation techniques, or adjustments to your bite if misalignment is a factor.

If attrition is advanced, your dentist can restore your teeth with crowns, veneers, or composite bonding to rebuild your bite and protect the remaining structure.
