It could have been an injury and it could have been general wear and tear, whatever it is one thing is certain.. it hurts ! The pain is real and there is a reason. This very well could be broken or cracked teeth.
It’s easy to find out self in this situation, a cracked tooth can result from many things, but more commonly from chewing on hard foods, grinding your teeth at night while you’re sleeping and unfortunately with time as you age it can happen. It’s a common condition and the leading cause of tooth loss in industrialised nations such as Australia.


  • pressure from teeth grinding
  • fillings so large they weaken the integrity of the tooth
  • chewing or biting hard foods
  • blows to the mouth, such as might happen with a car accident, sporting injury, fall, or even a fistfight
  • abrupt changes in temperature in the mouth — for instance, from eat something extremely hot and then trying to cool your mouth with ice water
  • age, with most teeth cracks occurring in people over 50



  • pain when chewing or biting, but the most pain when you release the bite
  • a development of sensitivity to heat, cold, or sweetness
  • the pain comes and then leaves, it is not continuous
  • inflammation/swelling of the gum where the effected areas are/could be

The types of cracked teeth 

  • Craze lines.
    These are super-small cracks in the enamel (the strong outer covering) of teeth. They cause no pain and don’t require any treatment.
  • Fractured cusp. 
    The soft center of the tooth where nerves, connective tissue, and blood vessels are, This kind of crack generally occurs around a dental filling. It usually doesn’t affect the pulp of the tooth and as a result doesn’t cause much pain.
  • Cracks that extend into the gum line.
    A tooth that has a vertical crack that extends through it but hasn’t yet reached the gum line is generally savable. However, if the crack extends into the gum line, that tooth may need to be extracted. Prompt treatment offers the best chance of saving the tooth.
  • Split tooth.
    This is a tooth with a crack that travels from its surface to below the gum line. It can actually be separated into two segments. With such an extensive crack, it’s unlikely the entire tooth can be saved, but your dentist may be able to save a portion of it.
  • Vertical root fracture.
    This type of crack begins below the gum line and travels upward. It often doesn’t produce much in the way of symptoms, unless the tooth becomes infected. Chances are the tooth will have to be extracted.

Understanding and identifying these five types can provide guidance for treating cracked teeth. The vertical order of these cracks, from top to bottom, signifies the general prognosis for a particular crack. That is, craze lines have a good prognosis, whereas a vertical root fracture has a very poor prognosis.

Do you need to act if you have cracked teeth? 

Yes. It is important to get advice as soon as possible to help the treatment be more effective. If they are not treated, cracked teeth can lead to the death of the nerve and an abscess might grow. The tooth could need root canal treatment or even taking out. In severe cases the tooth can actually split in two. If this happens your dentist will not be able to save the tooth and it will need to be taken out.
