FAQ on Endodontics

“Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. 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.

What are the signs of needing endodontic treatment?

Signs to look for include pain, prolonged sensitivity to heat or cold, tenderness to touch and chewing, discoloration of the tooth, and swelling, drainage and tenderness in the lymph nodes as well as nearby bone and gingival tissues. Sometimes, however, there are no symptoms.

How does endodontic treatment save the tooth?

The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the canal, a channel inside the root, 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.

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 should I expect in an Endodontic Procedure?

Endodontic treatment can often be performed in one or two visits and involves the following steps:

1. 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.

2. 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.

3. 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

4. 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.

Will the tooth need any special care or additional treatment after endodontic 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 for a full restoration as soon as possible. Otherwise, you need only practice good oral hygiene, including brushing, flossing, and regular checkups and cleanings.  Please refer to the instructions given to you at the office or to see them online, click here.

What causes an endodontically treated tooth to need additional treatment? Why do I need another endodontic procedure?

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, redoing the endodontic procedure can save the tooth. As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:

• Narrow or curved canals were not treated during the initial procedure
• Complicated canal anatomy went undetected in the first procedure
• The placement of the crown or other restoration was delayed following the endodontic treatment
• The restoration did not prevent salivary contamination to the inside of the tooth

In other cases, a new problem can jeopardize a tooth that was successfully treated.

For example:

• New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth
• A loose, cracked or broken crown or filling can expose the tooth to a new infection
• A tooth sustains a fracture

What are the alternatives to retreatment?

If nonsurgical retreatment is not an option, then endodontic surgery should be considered. This surgery involves making an incision to allow access to the tip of the root. Endodontic surgery may also be recommended in conjunction with retreatment or as an alternative. Your endodontist will discuss your options and recommend appropriate treatment.

Why would I need endodontic surgery?

• Surgery can help save your tooth in a variety of situations
• Surgery may be used in diagnosis. If you have persistent symptoms but no problems appear on your x-ray, your tooth may have a tiny fracture or canal that could not be detected during nonsurgical treatment. In such a case, surgery allows your endodontist to examine the entire root of your tooth, find the problem, and provide treatment.
• Sometimes calcium deposits make a canal too narrow for the instruments used in nonsurgical root canal treatment to reach the end of the root. If your tooth has this “calcification,” your endodontist may perform endodontic surgery to clean and seal the remainder of the canal.
• Usually, a tooth that has undergone a root canal can last the rest of your life and never need further endodontic treatment. However, in a few cases, a tooth may not heal or become infected. A tooth may become painful or diseased months or even years after successful treatment. If this is true for you, surgery may help save your tooth.
• Surgery may also be performed to treat damaged root surfaces or surrounding bone.

Although there are many surgical procedures that can be performed to save a tooth, the most common is called apicoectomy or root-end resection. When inflammation or infection persists in the bony area around the end of your tooth after a root canal procedure, your endodontist may have to perform an apicoectomy.

 

What is an apicoectomy?

In this procedure, the endodontist opens the gum tissue near the tooth to see the underlying bone and to remove any inflamed or infected tissue. The very end of the root is also removed.A small filling may be placed in the root to seal the end of the root canal, and a few stitches or sutures are placed in the gingiva to help the tissue heal properly. Over a period of months, the bone heals around the end of the root.

Will Endodontic Surgery hurt?

Local anesthetics make the procedure comfortable. Of course, you may feel some discomfort or experience slight swelling while the incision heals. This is normal for any surgical procedure. Your endodontist will recommend appropriate pain medication to alleviate your discomfort. Your endodontist will give you specific postoperative instructions to follow. If you have questions after your procedure, or if you have pain that does not respond to medication, call your endodontist. Click here to view surgery instructions

What are the alternatives to endodontic surgery?

Often, the only alternative to surgery is the extraction of the tooth. The extracted tooth must then be replaced with an implant, bridge, or removable partial denture to restore chewing function and to prevent adjacent teeth from shifting. Because these alternatives require surgery or dental procedures on adjacent healthy teeth, endodontic surgery is usually the most biologic and cost-effective option for maintaining your oral health. No matter how effective modern artificial tooth replacements are—and they can be very effective—nothing is as good as a natural tooth. You’ve already made an investment in saving your tooth. The payoff for choosing endodontic surgery could be a healthy, functioning natural tooth for the rest of your life.

How much will my procedure cost?

For Root Canals, cost varies depending on how complex the problem is and which tooth is affected. Molars are more difficult to treat, the fee is usually more. Most dental insurance policies provide some coverage for endodontic treatment. Generally, endodontic treatment and restoration of the natural tooth are less expensive than the alternative of having the tooth extracted. An extracted tooth must be replaced with a bridge or implant to restore chewing function and prevent adjacent teeth from shifting. These procedures tend to cost more than endodontic treatment and appropriate restoration. With root canal treatment you save your natural teeth and money. For retreatment, the cost varies depending on how complicated the procedure will be. The procedure will probably be more complex than your first root canal treatment, because your restoration and filling material may need to be removed to accomplish the new procedure. In addition, your endodontist may need to spend extra time searching for unusual canal anatomy. Therefore, you can generally expect retreatment to cost more than the initial endodontic treatment. While dental insurance may cover part or all of the cost for retreatment, some policies limit coverage to a single procedure on a tooth in a given period of time. Check with your employer or insurance company prior to retreatment to be sure of your coverage. Click here for more information regarding insurance, payments, and financing.
