Abfraction

What is abfraction?

Abfraction is the loss of tooth structure where the tooth and gum come together. The damage is wedge-shaped or V-shaped and is unrelated to cavities, bacteria, or infection.

Abfraction is usually painless, but tooth sensitivity can become a problem, especially where heat and cold are concerned.

You may never develop other signs or symptoms, but if the damage continues, it could lead to:

  • worn and shiny facets on the tooth, known as translucency
  • chipping of the tooth surface
  • loss of enamel or exposed dentin
  • Over time, loss of enamel can make the tooth vulnerable to bacteria and tooth decay. It can affect the structural integrity of the tooth, leading to loosening of the tooth or tooth loss.

What causes abfraction?

Abfraction is caused by long-term stress on the teeth. This can happen in a variety of ways, such as:

  • bruxing, also known as teeth grinding
  • misalignment of the teeth, also called malocclusion
  • mineral loss due to acidic or abrasive factors
  • Sometimes there are multiple contributing factors. Your dentist may not be able to tell you exactly why it happened. Also, abfraction can occur along with other dental problems like abrasion and erosion.

How is abfraction treated?

Abfraction doesn’t always require treatment, but it’s important to see your dentist to be sure.

Even if you don’t need immediate treatment, monitoring may help you head off bigger problems.

Some treatment options are:

  • Fillings. This can be helpful if it’s getting hard to keep your teeth clean or if you have tooth sensitivity due to exposed nerve endings. Your dentist can choose a color to match your teeth, so it’s also a good aesthetic option.
  • Mouthguard. If you clench or grind your teeth at night, your dentist can fit you with a mouthguard to prevent further damage to your teeth.
  • Toothpaste. Toothpaste won’t cure abfraction, but certain products can help cut down on tooth sensitivity and abrasion.
  • Orthodontics. Realigning your bite can help prevent future damage, which can be especially helpful for younger people.
