Although you may have sensitive teeth now, there are ways you can help to improve your gums and your teeth. There are several toothpastes out there on the market that contain potassium nitrate, which helps to reduce pain and discomfort associated with sensitivity. Although there are several toothpastes to choose from, Sensodyne is the preferred. The first type of crack is known as an oblique supragingival fracture. This fracture is found above the gums, and normally happens when you bite down too hard on something. Normally, this fracture doesn t involve the nerve. Once the fractured area of the tooth breaks off, the pain will go away. Although the exposed dentin may cause you some pain, you can visit the dentist and have it repaired. The pulp exists inside of the tooth, and can spread to abscess if it isn t taken care of. The tissue in the pulp is kept alive by the blood vessels that come from the tip of the root and travel along the root canal into the tooth. Decay is the main reason for pulp in the tooth dying. Once the decay has reached the pulp, it will keep eating away until the pulp has died. You shouldn t force the tooth into place, rather try and jiggle it around. You can also use moist tissue to hold the tooth in place, until you can get to a dentist. If you ve got a fractured tooth, the treatment will all depend upon how bad the booth has been fractured. No matter how light the fracture may be, it is very important that you get to a dentist as soon as you can. When the wisdom teeth first come in, they will sometimes be impacted. Impacted teeth will normally need to be extracted. Sometimes they can be pulled, although in most cases they need to be cut out by a qualified surgeon. When the time comes to have your wisdom teeth extracted, you ll need to go to an oral surgeon and have a consultation first. Using various tools and equipment, he will go down inside of the tooth and scrape away the nerves and dead pulp. This is a very effective procedure, although very time consuming as well. In most cases, a root canal can take several hours, although it is the only way to stop the dying pulp and save the tooth.
