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. These fractures can be nothing to worry about at times, yet painful with other cases. 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. Composite fillings are a common type of material, as they match the color of your teeth. The material that makes up the composite filling is mixed then placed directly in the cavity, where it hardens. They last several years, although composite isn t recommended for large cavities, or areas where they may chip. Once the infection has started to spread, your jawbone may start to dissolve as it makes room for the swelling in the area that has been infected. Once the bone starts to dissolve, the pressure will be greatly reduced, although the infection will still be there. Even though you will get relief, the infection will get worse - and the pain will always come back. Depending on the shape, size, and the formation of the wisdom teeth, the removal process can vary from easy to hard. 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. Even though you may not realize it, regular cleaning visits to your dentist is the best way to keep your teeth healthy, and prevent problems such as decay and cavities. You can use several techniques to overcome dental anxiety. Some of the techniques require mild sedatives, also referred to as sedation.
