![]() ![]() ![]() The tissue around an infected tooth also becomes very acidic which partly neutralizes the anesthetic. When you have a severe toothache, the pain signal going to the brain is so much stronger that it is very much more difficult to stop. However, by far the most important reason for how difficult it is to get the tooth numb is whether it is inflamed or infected. The lower back molars are much more difficult to get numb because the bone is so thick around them that anesthetic has trouble soaking through and there are several different nerves that go to them. Most lower teeth are also easy except the back molars. Most upper teeth are easy to get numb for an extraction. ![]() However there are exceptions depending on which tooth and whether you have toothache or not. If they are not infected, and in thick bone, expect it to take a while.Įxtractions are generally easier to get a patient numb for than a filling. In a few cases, they are not easy to remove. In most cases, these teeth are infected and easy to remove. Some teeth are fractured at gum level and there is not much to grab. They are very difficult to predict and will involve dividing the tooth into about 20 pieces to take out. Ankylosis is a condition that affects some tooth where the bone actually fuses with the tooth. If the bone is thick, your tooth will be hard to remove as the bone will not flex much. Some people have very thick bone around the teeth and some have thin. They cannot be removed unless you fracture/remove the bone, or divide the tooth into individual roots. These roots often are curved in different directions effectively locking the tooth into the bone. Back teeth have two or three roots (sometimes four) whereas front teeth have one. Back teeth are almost always more difficult than front teeth.However, some teeth are very difficult to remove. So it will usually take longer to get numb than to get out. If your tooth is wobbly from gum disease, then the gum disease has removed most of the bone around the tooth. These teeth almost always should be sectioned (divided so that each root is like a single extraction rather than trying to remove two or three roots together) if you don’t want to fracture a lot of bone off. However most of your back teeth have two or three roots and cannot just be “pulled out” without breaking something. Many of the front teeth are round, so they can be removed without damaging bone quite easily. Usually this is done by spending more time loosening the tooth with luxators (special fine instruments that slip down beside the tooth loosening it up) or by sectioning (dividing the tooth into little pieces that are easily removed from within the socket without having the wriggle the tooth from side to side at all. However it takes more time, and a lot more attention to detail. In the vast majority of cases, a tooth can be removed without damaging the surrounding bone. Loss of bone or gum tissue can make dentures painful to wear as the thin flimsy remaining gum tissue gets pinched between the denture and the sharp blade of bone remaining from the inside of the extraction socket.It can make it more difficult to get a stable denture in the long term.It may mean you need large soft tissue grafts if you are having an implant or a bridge to replace the tooth at some point in the future. It may mean you need large bone grafts to correct the defect if you are having an implant or a bridge placed.ģ. It causes a shadow above the replacement tooth if you replace it with a bridge or an implant.Ģ.Unfortunately, the removal of the bone plate from the outside of the socket causes the socket to immediately fill with gum tissue causing major loss of bone volume and eventually gum volume. It also makes the area heal quickly and usually without pain. This immediately released the tooth and made it come out quickly. This fractured the plate of bone on the cheek side of the tooth that was holding the tooth in. In many of the older extraction techniques, the tooth was wriggled side to side and eventually leaned outward toward the cheek. Implants.Īll of these do better when the bone that held the tooth in is preserved as much as possible. This bone is crucial for almost all types of tooth replacement. Removing the bone.Ī tooth is held in by the bone that surrounds it. The first thing you need to know about extractions is that they can be done in largely two ways. Will you ever want to replace the tooth ever again in your lifetime? Like any procedure, an extraction can be done very well, or very poorly. However, in the popular imagination, removing a tooth is a simple procedure that anyone can do and the result is the same. The removal of a tooth is the oldest form of dental treatment and is still useful in many instances. ![]()
