Dry mouth is very common, and is normally the result of medications, illness, and radiation treatment. Tobacco users will also suffer from dry mouth, as the tobacco will use up the saliva in the mouth and leave the user with nothing to keep his or her mouth moist. Cavities are a very serious situation, and if left untreated, can result in the destruction of the tooth. If the root tips have managed to wrap themselves around the bone, the removal process can be very time consuming and quite painful. Once the extractions have been completed, there is normally little to no swelling involved. Your dentist will prescribe you some pain medicine, which you should use as soon as you arrive home. Native Americans for example, used the inner bark found in the butternut tree to their gums to get relief from toothaches. The butternut tree is found in North America, and is also the cousin of the black walnut tree. Butternut trees are found along rivers in well drained soil, rich woods, and even in back yards. 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. It s recommended by dentists as being the best, simply because it affects the nerve of the tooth and stops the pain where it starts. If a dentist has a lot of customers, it lets you know that he has them for a reason. People that are satisfied with a dentist, normally return. If you suffer from dental anxiety, you should always let your dentist know in advance. This way, he work with you to overcome your fear. Over time, you ll find that you can overcome your fear and establish a great relationship with your dentist. Although the exposed dentin may cause you some pain, you can visit the dentist and have it repaired. If the fracture is large, you may need to have a crown placed on the tooth to prevent further fractures from occurring in that tooth. The second type of crack exceeds way below the gum line, and is known as an oblique subgingival fracture.
