What is Abfraction?

Abfraction is enamel damage that happens when pressure is placed on a tooth, usually during improper tooth alignment or grinding habits. This can cause notches in the teeth that lead to sensitivity or pain when eating hot or cold foods. In severe cases, the abfraction can lead to tooth loss and may require restorative treatments such as fillings or crowns.

The best way to prevent abfraction is to practice good oral hygiene habits and wear mouthguards if nighttime bruxing is a concern. If your teeth are already showing signs of abfraction, your dentist will use treatment to smooth out the teeth so they’re more comfortable again. In many cases, cosmetic procedures like veneers or bonding can be used to fix the appearance of the affected teeth. However, if the damage to the tooth is too severe, you may need a crown to protect the tooth from further damage.

When is Abfraction a concern?

Abfractions are often caused by bruxism, or teeth grinding and clenching. This can be caused by a misaligned bite or by stress and anxiety. While abfractions are common, they can be quite painful and should be treated as soon as possible. Abfractions are sharper than abrasions. Abrasions damage the enamel, which causes the gums to recede over time. However, once an abfraction forms, it cannot be reversed. Fortunately, there are several treatment options available to treat abfractions.

If the tooth is still healthy otherwise, we may recommend a specialized toothpaste to protect the vulnerable tooth from further damage. The toothpaste will contain fluoride and potassium nitrate to help rebuild and strengthen the tooth enamel. With regular use, it will help to prevent additional damage from progressing. If your tooth decay is more advanced, we will likely recommend a dental crown. Dental crowns are restorations that fit over damaged teeth to restore their shape and appearance. They are made from porcelain or ceramic so they will blend in with your smile for natural-looking results. Since they are custom-made, they also offer excellent protection for the damaged tooth.
