Relieve tooth aches and repair deep cavities with Aurora dentist, Dr. Harry Weingarten!
Root canals are the hollow channels reaching from the central chamber to the bottom of the tooth roots. If you suffer from tooth pain or have a deep cavity, an endodontist may determine that a root canal procedure is necessary.
Root Canal Symptoms and Treatment
It is important to visit a dentist who specializes in endodontics when symptoms of a root canal problem first emerge. If you experience tooth pain or if it turns out you have a deep cavity, the endodontist may determine that a root canal procedure is necessary.
The endodontist will first take x-rays to find out how close the damage is to the nerve inside the pulp chamber of the tooth. Often, if a cavity is found to be near the pulp, the pulp will have already become infected. In this case a root canal procedure will eliminate the pain and remove any infected tissue.
Root canal treatment starts by cleaning out damaged areas of the tooth. This is generally performed under local anesthetic, so the root canal procedure is generally no more uncomfortable than getting a filling. Once the endodontist has breached the pulp chamber, further anesthetic may be injected directly into the nerve of the tooth. This effectively deadens any further pain.
The endodontist removes the tissue within the pulp chamber and clears any remaining nerve tissue from the root canals. Once the dental pulp tissue has been cleared, the dentist widens the root canal slightly and straightens the pulp chamber to prepare it for filling. The inside of the tooth is then disinfected.
When the tooth has been properly prepared, the endodontist fills the root canals with a rubber-like material called gutta-percha filling. The pulp chamber is packed with cotton, and a temporary filling is used to seal the opening. During a succeeding visit, your endodontist removes the temporary filling, fills the pulp chamber with a core buildup, and then repairs the tooth with a filling or crown. During this visit, your endodontist will also check for root canal procedure complications such as infection.
Root canal procedures have earned a misleading reputation for pain. The reality is that in most cases the pain after a root canal treatment is less than the throbbing that you would experience by leaving damaged root canals untreated.
If you are concerned about post-surgery pain, discuss your fears regarding root canal surgery with your endodontist prior to treatment. There are a variety of sedation dentistry methods that can be used to make your experience more comfortable and stress-free.
