The crack can be present for many years, before you start to feel any pain. To be on the safe side, you should go to your regular checkups with your dentist, as he can check for cracks and other problems. The oblique root fracture is next, although it doesn t involve the tooth crown at all. This type of fracture is almost always found below the gums, normally under the bone. If you have chosen either laughing gas or an IV sedation, your dentist will administer either of the two before he gives you shots or goes any further. Once the medicine has taken effect, you normally won t feel anything or remember it. Laughing gas and IV sedation can put your mind at ease, so you won t be uncomfortable during your surgery or extractions. If the bristles start to get worn down, they can tear away at your gums, leading to sensitivity. To get the most from your brushing, you should always use a bit of common sense and ask your dentist for his recommendations. Brushing your teeth will help keep them healthy, and prevent the buildup of plaque and tartar. Sometimes, toothaches can result from medical conditions and have nothing to do with dental. In most cases, if the problem goes without being checked, it can lead to serious trouble and maybe even become a life threatening situation. Normally, when you have a toothache, you ll experience tremendous pain. The pain can be so intense at times that you will be willing to do anything to stop the pain - even for a few minutes. Once the socket has been packed, you will be relived from pain for a day or so. If you go back to your dentist, he will remove the old packing, wash the socket out, and place a new packing in. Providing the pulp hasn t been damaged, your dentist will be able to restore the full shape and function to the fractured tooth. In cases where pulp damage has occurred, the dentist may need to do a root canal or other type of serious surgery to repair the tooth. Whenever you encounter a dental emergency, you shouldn t hesitate to contact a dentist immediately.
