Falling, tooth injury or biting down something really hard can lead to chipped, fractured (cracked) or broken tooth. Chipped or broken tooth is more serious than a fractured one. There are two angles in treating a broken tooth, cosmetic and pain management. There is no way you can repair it at home. You need to see a dentist as soon as possible or else your tooth can become infected, which may result in further damage. If your tooth is just chipped, your dentist will repair it with a filling. Bonding can be done if the concerned tooth is in front.
If a large part of tooth is broken nerves of the tooth can be exposed causing pain when coming in contact with saliva, air, hot or cold food and drinks. Painkillers like Ibuprofen and acetaminophen can be taken as they are available over the counter. Warm water gargle will also help relieve pain until the dentist takes care of the situation. The dentist will perform a root canal treatment where the nerves are damaged or exposed and cover it with a crown, which is a tooth-shaped cap and thus save the tooth. Crowns can be made from materials like metal, resin, or ceramic. If there is bleeding a piece of gauze can be pressed over it or cold water can be kept in the mouth for a while until the blood clots.
