Cracked Tooth 😬. Have you ever bitten into something and it sent a shooting pain right up your tooth? This is usually because you just cracked your tooth. Teeth can crack for a variety of reasons; you have a large cavity in the tooth, or a large filling, you grind or clench your teeth, or you bit into something really hard. No matter why your tooth cracked, it's going to need to be treated. The reason why it hurts when you eat something, is because the pressure from the food presses against part of the tooth and is wedging it away from the rest of tooth. This sends a pain signal to the pulp. Depending on how deep the crack goes into the tooth, you may need one of a variety of treatments. The more surface the crack, the more simple the treatment. If the crack is only extending into the dentin of the tooth, the layer just below the white enamel that you can see in your mouth, the tooth will just need a crown to reinforce and protect the tooth. Usually the degree of pain that you feel when you are chewing is mild to moderate with a crack in the dentin. If the crack extends to the pulp of the tooth that houses the nerve tissue, usually a root canal treatment will need to be completed to relieve the pain before a crown can be placed to reinforce the tooth. The pain associated with a crack that extends to the pulp is moderate to severe. Occasionally, the crack extends below the level of the bone and pressure will continue to cause pain because the fibers that connect the bone to the tooth will be fired off. In this scenario the only way to relieve the pain is to remove the tooth. Without treatment, cracked teeth worsten from the more simple scenarios to the more complex, because the forces applied to the tooth cause the crack to grow deeper in the tooth. If you have symptoms like the ones mentioned in this article, it is best to seek help quickly to avoid more pain, and extensive, costly treatments.
