Learn about everything you need to know when it comes to hairline tooth fractures and what you can do to combat them below.

Hairline Tooth Fracture: Explained

The hairline tooth fracture is a small crack located right in the tooth. When not addressed, this fracture can lead to tooth loss and other oral health issues. There are a variety of different hairline tooth fracture cracks, including:

  • Craze Lines: These cracks are minuscule and appeal to the tooth enamel. They do not trigger any pain or require any immediate treatment.
  • Vertical Crack: A vertical fracture runs vertically up and down the tooth. If this fracture does not impact the gum line, there is a high probability that the tooth can be saved. However, if the crack has extended onto the gum line, the tooth will most likely need to be removed.
  • Split Tooth: A split tooth has a crack that separates the tooth into two separate components. When the fracture is extremely large, the tooth will most likely need to be extracted completely.
  • Fractured Cusp: Fractured cusp cracks often occur around a dental filling. They usually do not impact the tooth’s pulp, therefore, they do not cause a lot of pain.

How Hairline Fractures Happen

There are a number of reasons hairline tooth fractures occur, including:

  • Chewing on hard foods or objects
  • Pressure on the jaw from tooth grinding or clenching
  • Injury to the jaw from sports or an accident
  • Fillings that are far too large and affecting the tooth’s integrity
  • Temperature changes in the mouth
  • Ageing

Treatments For Hairline Tooth Fractures

The treatment for hairline tooth fractures is based on exactly where the crack is located, how large it is, and whether it has extended to the gum line. The following dental solutions may be recommended by the dentist:

  • Bonding: During the tooth bonding process, our dentist applies a plastic resin onto the tooth to fill in the fracture. This is often used for small hairline fractures.
  • Crown: The dental crowns solution our Sarnia dentists use are fitted and cap the cracked tooth perfectly to protect it.
  • Root Canal: When the fracture has reached the tooth’s pulp, having a root canal procedure one can remove the pulp and restore the tooth.
  • Tooth Extraction: When the tooth, the tooth roots and the nerves are deteriorating or damaged, the only solution may be to have it extracted completely.
