What is a root canal?
To understand root canal, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves, and connective tissue and creates the surrounding hard tissues of the tooth during development.
The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root. The pulp is important during a tooth's growth and development. However, once a tooth is fully mature it can survive without the pulp, because the tooth continues to be nourished by the tissues surrounding it.
Why would I need a root canal surgery procedure?
A root canal procedure is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, or a crack or chip in the tooth. In addition, a blow to a tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abcess, so a root canal surgery procedure at our Nashville office is recommended.
Signs of pulp damage include pain, prolonged sensitivity to heat or cold, discoloration of the tooth, swelling and tenderness in the nearby gums. Sometimes, there are no symptoms to indicate if a root canal procedure is necessary.
How does a root canal save the tooth?
Our Nashville dentist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the tooth, then fills and seals the root canal after the procedure. Afterwards, you will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth.
Will I feel pain during or after the root canal procedure?
Many root canals are performed to relieve the pain of toothaches caused by pulp inflammation or infection. With modern techniques and anesthetics, most patients report that they are comfortable during the procedure.
For the first few days after treatment, your tooth may feel sensitive, especially if there was pain or infection before the procedure. This discomfort can be relieved with over-the-counter or prescription medications and by following your Nashville dentist's instructions after the root canal procedure carefully.
Your tooth may continue to feel slightly different from your other teeth for some time after your root canal surgery procedure is completed. However, if you have severe pain or pressure or pain that lasts more than a few days, call your Nashville dentist.
Root canals can often be performed in one or two visits and involves the following steps:
The dentist examines and x-rays the tooth, then administers local anesthetic. After the tooth is numb, the dentist places a small protective sheet called a "dental dam" over the area to isolate the tooth and keep it clean and free of saliva during the root canal procedure.
The dentist makes an opening in the crown of the tooth. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling.
After the space is cleaned and shaped, the dentist fills the root canals with a biocompatible material, usually a rubber-like material called "gutta-percha." The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed by your dentist before the tooth is restored.
After the final visit with your dentist, you must return to your dentist to have a crown or other restoration placed on the tooth to protect and restore it to full function.
If the tooth lacks sufficient structure to hold the restoration in place, your dentist or dentist may place a post inside the tooth. Ask your dentist at our Nashville location for more details about the specific restoration planned for your tooth after your root canal procedure.
Will the tooth need any special care or additional treatment?
You should not chew or bite on the treated tooth until you have had it restored by your dentist. The unrestored tooth is susceptible to fracture, so you should see your dentist at our Nashville office for a full restoration as soon as possible. Otherwise, you need only practice good oral hygiene, including brushing, flossing, and regular checkups and cleanings.
Most teeth treated by a root canal last as long as other natural teeth. In a few cases, a tooth that has undergone a root canal fails to heal or the pain continues. Occasionally, the tooth may become painful or diseased months or even years after successful treatment. Often when this happens, another root canal procedure can save the tooth.
How Much do Root Canals Cost in Nashville?
The price for your root canal will depend on the tooth that is being treated. Some teeth have only one root, while others have two or three. The more roots there are, the longer and more complex the procedure becomes (impacting the price.) Putting your root canal off altogether could cost you even more. If your tooth needs to be extracted, you’ll have to consider getting a bridge or dental implant.
