Fractured And Broken Teeth

Tooth enamel is the hardest substance in the body. The shiny white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body – making it durable and damage resistant. Teeth are remarkably strong, but they can chip, crack (fracture) and result in a broken tooth. This can happen in several ways:

  • Biting down on something hard
  • Being hit in the face or mouth
  • Falling
  • Having cavities that weaken the tooth
  • Having large, old amalgam fillings that don't support the remaining enamel of the tooth

When a tooth chips or breaks, it may not necessarily hurt. Your tongue usually feels the sharp area quite quickly. Minor tooth fractures usually don't cause pain, but if a large piece of the tooth breaks off, it can hurt. The nerve inside the tooth may be damaged. Extreme discomfort also can happen when nerve endings in the dentin are exposed to air, or to hot or cold foods or drinks.

Pain from a broken or cracked tooth may be constant or may come and go. Many people feel pain when they chew because chewing puts pressure on the tooth.

What You Can Do

Cracked (fractured) Teeth
Whether your tooth cracks from injury or general wear and tear, you will experience a variety of symptoms ranging from erratic pain when you chew your food to sudden pain when your tooth is exposed to very hot or cold temperatures. In many cases, the pain may come and go and your dentist may have difficulty locating the tooth causing the discomfort.

There is no way to treat a cracked tooth at home. You need to make an appointment at the dentist. Sometimes the tooth looks fine, but it hurts when you eat or when the temperature in your mouth changes, drinking something hot or cold. If your tooth hurts all the time, it may have a damaged nerve or blood vessels. This is a serious warning sign that should not be ignored. You will know if you have a cracked tooth if it does not hurt to bite on the tooth, but pain occurs when you release the bite.

Endodontists specialize in saving cracked teeth and will cater treatment to the type, location, and extent of the crack. The sooner your tooth is treated, the better the outcome. Once treated, most cracked teeth continue to function as they should, for many years of pain-free biting and chewing.

3 Common Tooth Fractures

  1. Small tooth fracture – Involve the enamel (the hard outer shell of the tooth) only and may not be visible to the human eye – usually a cosmetic issue.
  2. Medium tooth fracture – Extend through the enamel and stop at the dentin (the softer tooth layer underneath the enamel). Can result in tooth sensitivity.
  3. Large tooth fracture – Extend through all three layers of the tooth to the pulp (tooth nerve). Noticeable pain and bleeding may occur.

Broken Teeth
If you have a broken tooth, see your dentist immediately. Your dentist is trained to use equipment available to assess whether the break was caused by a cavity, and if the tooth's nerve is in danger. A damaged nerve usually require root canal treatment.

Until you get to the dentist's office:

  • Rinse your mouth well with warm water to clean the area surrounding the affected tooth.
  • Apply pressure with a piece of gauze on any bleeding areas for about 10 minutes or until the bleeding stops. If this doesn't work, use a tea bag with pressure on the area to stop the bleeding.
  • Apply a cold pack to the cheek or lips over the broken tooth. This will help reduce swelling and relieve pain.
  • If you can't get to your dentist right away, cover the part of the tooth that is in your mouth with temporary dental cement. You can find this at a pharmacy.
  • Take an over-the-counter pain reliever.

What Your Dentist Will Do

There are several types of tooth fractures and breaks, each of which requires different treatments. These include:

  • Minor cracks —Also called "craze lines," these are surface cracks that affect only the outer white surface of the tooth, called the enamel. Minor cracks rarely need treatment. However, your dentist may lightly polish the area to smooth out any rough spots.
  • Cracked Tooth— this type of fracture involves the whole tooth, from the chewing surface all the way down to the nerve. The pieces remain in place, but the crack gradually spreads. Cracks can sometimes be repaired with filling material. The tooth often will need a crown to prevent the crack from getting worse. If the pulp (nerve and other live tissues) is damaged, you may need a root canal as well.
  • Chips — Minor chips don't always need treatment. Your dentist may suggest repairing the damage with filling material to prevent it from getting worse or to make the tooth look and feel better. If the chip is very small, the dentist may polish and smooth out the chipped area.
  • Broken cusp — these breaks affect the pointed chewing surfaces (the cusps) of the teeth. They usually do not affect the pulp and are unlikely to cause much pain. Your dentist may repair the damage to restore the tooth's shape. Frequently, however, an onlay or crown will be required.
  • Serious breaks — these breaks go deep enough to expose the nerve. They almost always cause the tooth to hurt and be sensitive. Usually, the broken part of the tooth will bleed. You will need root canal treatment to remove the exposed nerve and probably a crown to restore the tooth to normal function so you can eat and chew properly.
  • Split tooth — this means that the tooth has split vertically into two separate parts. Some teeth, such as your back teeth (molars), have more than one root. It may be possible to keep one of the roots, which will then be covered with a crown. First, you will need root canal treatment. Second, the dentist will remove any roots that cannot be kept. Third, you will need a crown to cover the root and replace the tooth. In some cases, when a root cannot be saved, the tooth will have to be removed.
  • Vertical breaks or split root —these cracks start in the root of the tooth and extend upward toward the chewing surface. These breaks are often painful because the area around the root may be inflamed or infected. In most cases, the tooth will have to be removed.

Decay-induced break — In this case, the tooth has broken or crumbled because a cavity weakened it from the inside out. Your dentist will evaluate the cavity and recommend the best way to restore the tooth. In some cases, if the decay is extensive and goes down to the bone, the tooth may have to be removed.
