Root Canal Therapy
Has your dentist or endodontist told you that you need a root canal? If so, you’re not alone. More than 15 million teeth are treated and saved each year with the root canal, or endodontic, treatment. This page explains root canal treatment in detail and how it can relieve your tooth pain and save your smile.
Reasons for root canals?
Root canal treatment is necessary when the pulp, the soft tissue inside the root canal, becomes inflamed or infected. There are a whole host of reasons why you might need root canal treatment:
- Deep decay, including around a crown
- Repeated dental procedures on the tooth
- Crack or chip in the tooth
In addition, an injury 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 abscess. There are many clinical reasons for needing root canal treatment, but there are also countless practical reasons why saving the natural tooth is a wise choice. Endodontic treatment helps you maintain your natural smile, continue eating the foods you love and limits the need for ongoing dental work. With proper care, most teeth that have had root canal treatment can last a lifetime.Root canals are needed for a cracked tooth from injury or genetics, a deep cavity, or issues from a previous filling. Patients generally need a root canal when they notice their teeth are sensitive, particularly to hot and cold sensations.
There are a few symptoms that mean you might need a root canal
- Severe pain while chewing or biting
- A “gum boil” or pimple on the gums
- A chipped or cracked tooth
- Lingering sensitivity to hot or cold, even after the sensation has been removed
- Swollen or tender gums
- Deep decay or darkening of the gums
How does endodontic treatment save the tooth?
The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the root canal, then fills and seals the space. Afterward, 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.
How long does it take to recover from a root canal?
Although you will most likely be numb for 2-4 hours following the procedure, most patients are able to return to school or work directly following a root canal. However, we advise against eating until the numbness is completely gone.
Will I feel any pain during or after the root canal?
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 a root canal?
“Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. Root canal treatment is one type of 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 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.
How is a root canal performed?
Endodontic treatment can usually be performed in one or two visits and involves the following steps:
- The endodontist examines and takes a radiograph of the tooth using x-rays, 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 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 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.
What happens after treatment?
When your root canal therapy has been completed, a record of your treatment will be sent to your restorative dentist. You should contact their office for a follow-up restoration within a few weeks of completion at our office. Your restorative dentist will decide on what type of restoration is necessary to protect your tooth. It is rare for endodontic patients to experience complications after routine endodontic treatment. If a problem does occur, however, we are available at all times to respond.
Will the tooth need any special care or additional treatment after endodontic treatment?
You should not chew or bite excessively on the treated tooth until you have had it restored by your dentist. The unrestored tooth is somewhat more susceptible to fracture, so you should see your dentist 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 endodontically treated teeth last as long as other natural teeth. In a few cases, a tooth that has undergone endodontic treatment does not heal or the pain continues. Occasionally, the tooth may become painful or diseased months or even years after successful treatment. Often when this occurs, other endodontic procedures can save the tooth.
How much will it cost?
The cost associated with this procedure can vary depending on factors such as the severity of damage to the affected tooth and which tooth is affected. In general, endodontic treatment is much less expensive than tooth removal and replacement with an artificial tooth.
