What is endodontic treatment?
To understand endodontic treatment, 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.
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.
How does endodontic treatment save the tooth?
The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the tooth, then fills and seals the space. Afterwards, you will return to your dentist, who will place a crown or other restoration on the tooth to protect it 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 procedure?
Many endodontic procedures 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. Follow your endodontist’s instructions carefully.
Your tooth may continue to feel slightly different from your other teeth for some time after your endodontic treatment is completed. However, if you have severe pain or pressure, or pain that lasts more than a few days, call your endodontist.
What is involved in an endodontic procedure?
Endodontic treatment can often be performed in one or two visits and involves the following steps:
The endodontist examines and X-rays the tooth, then administers local anesthetic. After the tooth is numb, the endodontist 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 procedure.
The endodontist 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 endodontist 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 endodontist, you must return to your dentist to have a crown or other restoration placed on the tooth to protect it and restore it to full function. If the tooth lacks sufficient structure to hold the restoration in place, your dentist or endodontist may place a post inside the tooth. Ask your dentist or endodontist for more details about the specific restoration planned for your tooth.
Can all teeth be treated endodontically?
Most teeth can be treated. Occasionally, a tooth can’t be saved because the root canals are not accessible, the root is severely fractured, the tooth doesn’t have adequate bone support, or the tooth cannot be restored. However, advances in endodontics are making it possible to save teeth that even a few years ago would have been lost. And, when endodontic treatment is not effective, endodontic surgery may be able to save the tooth.
What are the alternatives to endodontic treatment?
When the pulp of a tooth is damaged, the only alternative to endodontic treatment is extraction of the tooth. To restore chewing function and to prevent adjacent teeth from shifting, the extracted tooth must be replaced with an implant or bridge. This requires surgery or dental procedures on adjacent healthy teeth and can be far more costly and time-consuming than endodontic treatment and restoration of the natural tooth.
No matter how effective modern tooth replacements are – and they can be very effective – nothing is as good as a natural tooth.
