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. Without visiting the dentist, it is impossible to tell whether or not you have a cavity. Most cavities develop below the gums, and you won t be able to see them. If the cavity exists in the tooth, you will be able to see it, as it will change the color of the affected area. If you notice a color change or a blackened area in your tooth, you should make an appointment with your dentist immediately. Crowns And Bridging A root canal is a dental procedure that all of us are familiar with. Root canals are something we all dread, although when someone else is getting the procedure most of us find it to be somewhat amusing. When someone asks for a root canal on the other hand, most of us, including dentists, find it to be very absurd to say the least. If you are already in pain when you visit the dentist, the shots will put your mind at ease and stop the pain almost immediately. If you have a tremendous fear of dental pain and simply cannot stand the thought of getting a shot, then you may be interested in laughing gas or IV sedation. Either of the two can help you relax before you the dentist applies numbing shots. A toothache will always come back, until you get the tooth taken care of. If you visit your dentist in time and he catches the problem early, he may be able to save your tooth. Normally, this will result in a filling, crown, or root canal, although you won t have to have the tooth removed. Dentists always look to save teeth, as they don t like to remove a tooth unless they absolutely have to. A Close Look At Wisdom Teeth Also known as the third set of molars, the wisdom teeth are the last set of teeth in the mouth to erupt, which normally happens around the ages of 17 - 25. For many years, there has been a lot of controversy as to the need to remove these teeth. If the teeth don t cause any harm or pain, they are normally fine to stay in place.
