What is endodontics?

Endodontics is a branch of dentistry recognized by the American Dental Association involving treatment of the pulp (the soft tissue inside the tooth containing nerves and blood vessels) and surrounding tissues of the tooth. Each of our teeth has roots below the gum line that attach the teeth to the bone. Inside each root is a channel or “root canal space” that contains the pulp. Bacteria that are introduced into the pulp as a result of tooth decay, periodontal disease, tooth fracture or other problems, can severely damage the pulp. When this occurs, an endodontic specialist removes the diseased pulp to save the tooth and prevent further infection and inflammation. This procedure is called endodontic treatment or root canal therapy. After successful endodontic treatment the tooth will continues to function normally.

What are other alternatives to endodontic treatment?

When the pulp of a tooth is damaged the only alternative to endodontic treatment (root canal therapy) is extraction of the tooth. It is always recommended that you replace any extracted teeth with a bridge or implant to restore function and to prevent adjacent teeth from shifting.

Why do I need root canal therapy?

Endodontic treatment (root canal therapy) is necessary when the pulp of your tooth becomes inflamed or infected. This can occur due to a variety of causes including deep decay, a restoration in the tooth that is very close to the pulp, a crack or chip in the tooth, or trauma to the tooth. If inflammation or infection of the pulp is left untreated it can cause pain and lead to an abscess in the bone.

Symptoms of pulp damage include pain, prolonged sensitivity to heat or cold, discoloration of the tooth and swelling or tenderness in the gums. Sometimes there are no symptoms.

Can my tooth be saved?

In most instances endodontic therapy can save your tooth. In some cases, however, we are unable to save a tooth due to bone loss, an inability to properly restore the tooth, or fractures within the tooth, we are unable to save a tooth.

Will I feel anything during the procedure?

With modern techniques and anesthetics, patients report that they are comfortable during the procedure. Root canal treatment usually involves no more discomfort than a routine filling.

How many visits are required?

In most cases one appointment is required to finish the procedure. However, multiple visits might be necessary to properly treat the tooth due to tooth anatomy or severity of infection.

How long will it take?

For most cases, the procedure will take approximately an hour.

How long will my treated tooth last?

Generally, as long as any other tooth in your mouth with proper brushing, flossing and maintenance.

How much will the procedure cost?

The fee for root canal treatment varies depending on the type of tooth. The range of fees for various procedures is available from our office upon request. However, this is only an estimate and we cannot precisely determine what your needs are without an examination by Dr Tahmasebi.

What should I expect after the root canal?

Your tooth may be sore and tender for a few days following treatment. General soreness and sensitivity to biting on the tooth are common after the procedure and are normal. We strongly recommend Ibuprofen/Advil/Motrin for any discomfort following the procedure. Most patients experience very minimal to no discomfort.

Should I be worried about the x-rays?

No. Modern dental radiography is the safest form of radiology used in medicine today. We use digital x-rays which emit 90% less radiation than traditional film.

What happens after treatment?

When your root canal has been completed, radiographs are sent to your referring dentist. You should contact your general dentist’s office immediately following completion of root canal therapy to schedule an appointment to replace the temporary filling in the crown of the tooth. It is recommended that you see your dentist within a couple weeks after completion of root canal therapy to have the temporary filling replaced with a permanent restoration. In most cases a crown is the recommended restoration.

What new technologies are being used?

In order to provide the best treatment for our patients we use the most up-to-date technology and techniques available in endodontics which include the following:

Surgical Microscope

We use a surgical operating microscope as needed. This provides enhanced visualization of the treatment area up to 25 times. This is especially beneficial for accurate visualization of complex anatomical cases, location of additional canals, and location of root fractures or defects.

Digital Radiography

Dental x-rays can now be taken using digital sensors that transmit the image directly into a computer program. This allows for adjustments to be made to the radiograph after it has been taken. Digital radiography makes it easier for patients to see and understand the doctor’s explanation of their case. Also, digital images are viewable instantaneously which can help to greatly decrease the amount of time it takes to complete the procedure. In addition, digital radiography can reduce the amount of radiation that each patient is exposed to by 90%.


If you need a second opinion then call our office. Please bring your x-rays or arrange for them to be sent to our office.

Stop Gum Disease with Routine Dental Visits

Don't let gum disease steal your health. If you experience symptoms or have not seen a dentist in the past six months, call us to schedule a checkup and oral hygiene consultation. Dr. Victor Terranova can also recommend tooth replacement options, such as dental implants, if you’ve lost teeth due to gum disease. He has placed approximately 3000 implants throughout his dental career as both oral surgeon and periodontist.
