Hairline cracks in teeth often can't be seen with a visible examination and may not appear on X-rays. However, painting a special dye on the tooth can make them visible. Cracked teeth generally first present themselves as a slight sensitivity to cold. Over time, as the crack expands [link widoczny dla zalogowanych], the sensitivity to cold increases, and the tooth may also become increasingly sensitive to heat [link widoczny dla zalogowanych], to foods that are sweet, sour or sticky, as well as pressure when a person is chewing.
Minor cracks or craze lines are surface cracks on the enamel. Because they are so shallow, they generally don't cause tooth pain and require no treatment. If the crack has resulted in a rough spot, the dentist can fix the tooth by polishing it to give it a smoother texture or can use a bonding agent over the crack to fill it in.
Causes of Tooth Cracking Range from Biting on Something Hard to Previous Dental Work
Don't chew on hard objects such as ice, unpopped popcorn kernels or pens.Avoid tooth clenching and grinding. (Consider taking relaxation classes to help deal with stress or exercise to burn off the stress.)Wear a mouthguard to protect teeth from tooth clenching or grinding during sleep.Wear a mouthguard or mask to protect teeth from injury during contact sports.
Symptoms of Cracked Teeth Include Sensitivity to Cold and Heat, Plus Pain
Cracked Tooth Treatment May Include Root Canal, Tooth Crowns or Tooth Extraction
Many people will experience the pain of a cracked tooth at some point. If discovered early, a dentist can fix cracked teeth fairly easily. If a tooth fracture is discovered too late, it's more likely that the dentist will have to extract the tooth because the damage is too extensive. At that point, tooth repair becomes painful and expensive.
While some causes of cracked teeth are not avoidable, others are lifestyle choices. According to the American Association of Endodontists (AAE), to avoid cracked teeth:
For more serious breaks or split teeth, cracked tooth repair is more complicated. The dentist will likely perform a root
For some patients, the pain from cracked teeth comes and goes; for others it is constant. When the pain reaches the continuous stage, it is usually a signal that the blood vessels or nerves have been damaged.

Abscessed Tooth
When the tooth crack extends below the enamel, it affects the pulp tissue in the center of the tooth. This tissue contains the nerves and blood vessels and can become infected and very painful. Without treatment, the infection can spread into both the surrounding gum tissue and bone, causing bleeding gums, pain and possible tooth loss.
Fractured teeth can occur in many ways. A common cause is biting on a hard surface, such as an unpopped kernel of popcorn, hard candies or nuts. Tooth grinding, internal tooth decay, an infection or an injury are also causes of tooth cracking. Even exposure to extremes of temperatures [link widoczny dla zalogowanych], such as eating hot food and washing it down with ice water, can cause tooth enamel to crack.
The American Association of Endodontists also has excellent diagrams showing different types of cracked teeth.
Uneven chewing pressure on a tooth causes wear on the surface and weakens it.Loss of a substantial portion of the original tooth because of previous cavity fillings or other dental processes cause deterioration in what is left of the tooth.Previous root canals cause tooth brittleness, making the tooth more susceptible to cracking.
The American Dental Association lists several other causes for a cracked tooth related to dental problems and previous dental treatments:
