Root Canal Therapy

An endodontic treatment to eradicate your root canal disease

When your teeth are damaged the inside of the tooth can become infected. Infected root canals can then have a bad effect upon the pulp of the tooth, i.e., the blood vessels and nerves inside. If you do nothing about this the infection can begin to damage the bone, causing pain and swelling. If this happens to one of your teeth, come see our dentist or endodontist to determine the best endodontic treatment (root canal therapy) to save the tooth.

About Root Canal Therapy


Root canal therapy at Precision Dental NYC in Astoria

Tooth pain can be debilitating, especially if it originates in the root of your tooth. It can be a throbbing or a stabbing pain. But pain that comes from the root of your tooth often means that the pulp has become infected and needs treatment.

Don’t ignore tooth nerve pain or control the pain with medication. If the cause is an infection, it can turn dangerous if left untreated. Call the professionals at our dental clinic, your family dentists. A root canal procedure can save the tooth, permanently resolving your pain.

Your restorative dentists have the skills and knowledge to painlessly perform root canal therapy. Their goal is to maintain your dental health. A root canal procedure is just another technique to keep your teeth healthy.

Causes of Tooth Nerve Pain

Most often, a toothache is caused by a cavity that just needs a filling. But if the damage is more severe or if the tooth is already weakened, a filling may not be adequate.

Only your dentist in Astoria, NY can determine if you need a root canal procedure, but some of the symptoms that may lead to a root canal include:

  • Untreated and extensive tooth decay
  • Intense tooth nerve pain
  • A tooth abscess: A tooth that looks darker than your other teeth, which indicates a dying pulp
  • A dental crown that’s become loose or faulty
  • A tooth that’s been broken, cracked or chipped, exposing its pulp

What Does Root Canal Therapy Involve?

A root canal procedure requires one or more appointments and can be performed by a dentist or endodontist (a root canal specialist).

While the tooth is numb, a rubber dam (a sheet of rubber) will be placed around the tooth to keep it dry and free of saliva. An access opening is made on top of the tooth and a series of root canal files are placed into the opening, one at a time, removing the pulp, nerve tissue, and bacteria. If tooth decay is present, it will also be removed with special dental instruments.

Once the tooth is thoroughly cleaned, it will be sealed with either a permanent filling or, if additional appointments are needed, a temporary filling will be placed.

At the next appointment, usually a week later, the roots and the inside cavity of the tooth will be filled and sealed with special dental materials. A filling will be placed to cover the opening on top of the tooth. In addition, all teeth that have root canal treatment should have a crown (cap) placed. This will protect the tooth and prevent it from breaking, and restore it to its full function.

After treatment, your tooth may still be sensitive, but this will subside as the inflammation diminishes and the tooth has healed.
You will be given care instructions after each appointment. Good oral hygiene practices and regular dental visits will aid in the life of your root canal treatment.

Do You Feel Any Root Canal Pain?

Our Astoria dentist performs painless root canal therapy. It starts with a topical numbing agent, followed by a shot of Novocain to deaden any root canal pain. Then:

  1. The dentist accesses the tooth pulp to remove the nerve, blood vessel, connective tissue and all infected material.
  2. After the tooth is flushed with a disinfectant or antibiotic, your tooth is cleaned and dried completely.
  3. In the root canal of the tooth, your dentist inserts a rubbery substance, then seals the tooth.
  4. Often, a crown is fitted over the tooth to protect it. You may receive a temporary crown while the permanent one is made. If so, you must return in several weeks to get the permanent crown.

You end up with an unnoticeable, completely functional, pain-free tooth that should give you years of use. Care for the crown as you do for your other teeth.

Recovery After Root Canal

You shouldn’t feel any pain after root canal therapy. You may feel temporary discomfort once the anesthetic wears off. You may experience temperature sensitivity, but that fades quickly. Your root canal recovery is like recovering from a filling. You can go right back to your normal daily routine the very next day.

Call your dentist if you notice any of the rare symptoms after your procedure that may indicate the need for a root canal retreatment, such as:

  • Swelling in the area of your root canal procedure
  • Any pain after root canal therapy after several days
  • Continued pain that becomes more intense
  • A reaction caused by allergies, such as hives or a rash
  • An uncomfortable bite or issues with your crown

When You Need Root Canal Retreatment?

If you have a crown problem, from either the temporary or permanent one, you may need to return to your dentist’s office for an adjustment. While that’s not a root canal retreatment, it does allow your dentist another look at his root canal work.

If the infection returns to the tooth, which is rare, then you may need a root canal retreatment. Sometimes, it happens no matter how well your dentist cleans and disinfects the canal. Even without the nerve in the pulp, you feel the pressure. This pain after root canal therapy means you may need a root canal retreatment, which involves repeating the procedure.

How Much Does a Root Canal?

Many factors influence your final root canal cost, including:

  • Whether you need additional procedures
  • If you’re so nervous, you want to take advantage of sedation dentistry
  • How difficult it is for your dentist to reach the affected tooth
  • Whether the infection has spread to other teeth or your gums and jaw
  • Which type of crown you have your dentist put over the tooth, such as a:
    • Porcelain crown
    • Zirconia crown
    • BruxZir crown
    • eMax crown

Your dental insurance may cover the cost of your root canal procedure. Don’t avoid root canal therapy if you need it. The staff at Precision Dental NYC help by offering affordable root canals.
