Persistent or Throbbing Pain
Severe or lasting tooth pain may indicate inflammation or infection inside a tooth, especially when it keeps you up at night or returns again and again.
Severe tooth pain may indicate inflammation or infection inside a tooth. After examining the tooth and obtaining appropriate imaging, our dental team can determine whether root canal treatment may preserve it, so you can keep your natural tooth and get back to eating and sleeping comfortably.

Every tooth has soft inner tissue, called the pulp, that runs through channels inside its roots. When tooth decay forms a cavity and spreads deep into the tooth, it can reach the pulp, and the infection can spread quickly and cause a lot of pain. A crack or other damage can lead to the same problem.
Root canal treatment removes the inflamed or infected pulp, cleans and seals the inside of the tooth, and addresses the source of the problem while allowing you to retain your natural tooth.
If a tooth is too damaged or infected to be predictably restored, we explain the alternatives, including dental implants to replace it.

Only an examination can confirm what is causing your symptoms, but these warning signs mean a tooth should be checked promptly.
Severe or lasting tooth pain may indicate inflammation or infection inside a tooth, especially when it keeps you up at night or returns again and again.
Discomfort when you bite down can point to a problem inside the tooth or in the tissues around its root.
Swelling near a tooth can be a sign of a dental abscess, a pocket of infection that needs prompt evaluation.
Pus or an unpleasant taste in the mouth can be a warning sign of infection around a tooth.
When decay or a crack reaches the inner pulp of a tooth, infection can spread and cause significant pain.
A fever that comes with tooth pain or swelling is a reason to call us right away.
Important: Facial or neck swelling accompanied by difficulty breathing or swallowing requires immediate emergency medical care. Do not wait for a dental appointment.
Root canal treatment at our office is led by a dentist who focuses on endodontic care, has treated more than 5,000 root canal cases, and continued his endodontic training at Montefiore Medical Center.
Because endodontic, restorative and surgical care all happen under one roof, if your tooth needs a crown, an extraction, or an implant after your evaluation, your care stays in one office.

If there is swelling and a severe infection, the root canals may be treated with an antibiotic paste for a few days, or antibiotics may be prescribed before the procedure. We explain each step before we begin.
We examine the tooth and take the imaging needed to see whether root canal treatment may preserve it.
The tooth is anesthetized first, so the area is numb before treatment begins.
The infected pulp is removed from the root canals, which are then cleaned, shaped, and irrigated with an antiseptic solution.
The canals are dried and filled with a biocompatible material. The tooth is then filled and often covered with a crown to restore its function.
Severe tooth pain? Don’t wait it out.

In many cases, a damaged or infected tooth may be treatable without extraction. Depending on the diagnosis, treatment may include a filling, crown, or root canal. The dentist will evaluate the tooth and explain whether it can be predictably restored.
Often, yes. After the root canals are cleaned and sealed, the tooth is filled and is often covered with a crown to restore its function. In some cases, a post is used to reinforce the tooth first. We explain the plan for your tooth before treatment.
