Infections in your teeth are serious and can also be painful. When bacteria enters your bloodstream, it can cause health complications all throughout your body. The only way to treat an infected tooth is with a root canal, or endodontic treatment. At National Dental Upper East Side, we can perform this procedure with the assistance of a rotary tool, preventing the spread of infection and saving the compromised tooth.


A root canal becomes necessary when your tooth is invaded by bacteria. Bacteria can enter your tooth in one of several different ways, such as a chip or crack that exposes the interior. Infection can also occur as a result of gum disease. The bacteria that enter your tooth quickly multiplies. The pulp becomes irritated and inflamed, causing serious damage.


One of the most obvious signs of an infection is dental abscess. An abscess forms as a result of bacteria spilling out of the root. It is a fluid filled sac that attempts to contain the infection. As the infection grows, the abscess grows, which can then cause damage to the jawbone. Other symptoms that indicate that a root canal is needed are:

  • Swelling in the face, or in the neck.
  • Bone loss in the jaw.
  • Pain that lingers, even after you have finished eating.
  • Lingering sensitivity, even after the trigger (cold or heat) is no longer present.

In some cases, you may not feel any symptoms at all. No symptoms does not mean that there is no infection, or that the infection is gone. Any infection found during your regular oral exams will need to be treated.

An oral exam is the only way to diagnose an infection. Along with a visual inspection, we will also take digital X-rays. These X-rays will help us to see any damage done to the bone, as well as any abscess that might have formed. X-rays are also helpful in making a treatment plan.


At National Dental Upper East Side, we use rotary endodontics to treat your root canal. We use a drill with a nickel titanium tip, rather than a manual stainless-steel file. There are several benefits associated with rotary endodontics. First, nickel titanium is up to 5 times more flexible than stainless steel, which means that there is less risk for complications, or damaging the interior of your teeth. The canals are cleaned more smoothly and in less time. The rotary tool is also quieter, which can be a great benefit to those who suffer from anxiety over a dental visit.

We start by drilling into the tooth after a local anesthetic is administered. The pulp is removed from the inside. The canals are then cleaned, shaped and disinfected. The tooth is filled and finally capped with a dental crown, which provides both strength as well as protection against a new infection.

Root canals help to save an infected tooth from being extracted. For more information on how our rotary endodontic treatment can help you, or if you suspect an infection in your tooth, contact National Dental Upper East Side today at (646) 736-2206!
