(Fractured Tooth; Cracked Tooth)
- Craze lines—shallow cracks that cause no pain and require no treatment
- Fractured cusp—breaks in the chewing surface of the tooth
- Cracked tooth—the tooth cracks from the chewing surface down toward the root of the tooth
- Split tooth—cracks down through the root, separating a section of tooth
- Vertical root fracture—cracks begin in the root and move up toward chewing surface

- Increased age—teeth wear down as we age
- Teeth with current tooth decay or damage
- Teeth that have been restored with silver alloy
- Chewing on hard foods like hard candy or ice
- Pain with chewing
- Chewing only on one side of your mouth to avoid discomfort
- Sharp pain when you bite down
- Pain with cold air
- Random pain
- Do you remember biting down hard on something?
- When do you notice pain?
- What types of food cause pain?
- Dye staining—a solution is put on the tooth to help see the crack
- Transillumination—passing a light through the tooth
- Periodontal probing—using special tools to look for the extent of crack
- Bite test—you will be asked to bite down on a stick to find the specific tooth causing problems
- X-ray—to look for certain defects, since not all fractures can be seen on x-ray
- Crown—a cap is placed over the tooth. A temporary crown will be placed at first to make sure it corrects the problem. A permanent crown will eventually be placed.
- Root canal—may be needed if there is severe damage to the pulp. A root canal clears out the damaged pulp and places a new filler in the tooth.
- Tooth extraction—the tooth may need to be removed if the crack extends below the gum line.
- Avoid chewing on hard objects such as ice, hard candy, popcorn kernels, or pens
- Wear a mouth guard for sports or recreational activities
- Don’t use your teeth to cut things or open plastic bags
- Avoid clenching or grinding your teeth
- Talk to your dentist if you grind your teeth at night
