A root canal filling at Sola Dental Spa is a two-part treatment in which Dr. Anne Gershkowitz, DDS, removes infected or inflamed tissue from inside a tooth and then seals and restores it, most often with a filling or crown, so the tooth can stay in your mouth instead of being extracted. For Staten Island patients dealing with a toothache that will not quit, this combination of root canal therapy and a durable filling is usually the most conservative way to save the natural tooth. If you think you might need one, you can review the process further on our services page.
A root canal filling clears out infected tissue from inside the tooth, disinfects and shapes the canal, and then fills the space before sealing the tooth with a filling or crown, typically finished in one to two appointments.
"Patients hear ‘root canal’ and brace for the worst, but the procedure itself is what relieves the pain, not what causes it. The infection is what hurts. Once we have cleaned it out and filled the tooth properly, most people are far more comfortable than they were walking in."
Dr. Anne Gershkowitz, DDS, Founder, Sola Dental Spa
A West Brighton patient came in after weeks of putting off a nagging ache near a back molar, assuming it would pass. By the time she was seen, the nerve was clearly infected, and the root canal filling she had been dreading turned out to be the thing that finally let her chew on that side again without wincing.
How do you know if you need a root canal filling?
Persistent tooth pain, sensitivity to hot or cold that lingers, swelling, or a darkening tooth are common signs the nerve inside a tooth is inflamed or infected.
Not every toothache means a root canal is coming, but a few signs point that way: pain that throbs on its own rather than only when you bite down, sensitivity that lingers well after the hot or cold trigger is gone, or a small bump on the gum near the tooth. Dr. Gershkowitz confirms the diagnosis with an exam and an X-ray before recommending treatment, since imaging shows exactly how far the infection has spread into the root.
What happens during the root canal filling appointment?
The tooth is numbed, the infected pulp is removed from inside the root canals, the space is cleaned and shaped, and the tooth is filled and sealed, often followed by a crown for extra strength.
After the area is fully numb, a small opening is made in the top of the tooth to reach the pulp chamber and root canals. The infected or inflamed tissue is removed, and the canals are cleaned, disinfected, and shaped. A biocompatible filling material seals the canals from the inside, and the access opening is closed with a dental filling. Molars that do heavy chewing work often need a crown afterward to prevent the weakened tooth from cracking.
Does a root canal filling hurt?
The procedure itself is done under local anesthesia and is generally no more uncomfortable than getting a standard filling, with mild soreness for a day or two afterward.
The pain most people associate with root canals actually comes from the infection itself, not the treatment. Once the area is numbed, patients typically feel pressure rather than pain during the appointment. Afterward, over-the-counter pain relief and avoiding hard foods on that side for a day or two are usually enough to manage any lingering tenderness.
| Symptom before treatment | What it usually means |
|---|---|
| Lingering hot or cold sensitivity | Possible pulp inflammation |
| Throbbing pain or swelling | Likely infection needing prompt evaluation |
| Darkening of the tooth | Sign the nerve tissue may no longer be healthy |
Staten Island patients who have been putting off a persistent ache often find that the appointment they were dreading is the one that finally ends the discomfort, not a preview of more of it. Related reading on how painful a root canal procedure really is covers the pain question in more depth.
Frequently asked questions
How long does a root canal filling take?
Most root canal fillings are completed in one to two visits, depending on the tooth and how complex the canal anatomy is.
Will I need a crown after my root canal?
Often, yes, especially on back teeth that handle heavy chewing forces. Dr. Gershkowitz will let you know at your visit whether your tooth needs one.
Can a tooth get reinfected after a root canal filling?
It is uncommon, but a cracked filling or new decay can occasionally let bacteria back in, which is why regular checkups matter.
Is a root canal filling better than pulling the tooth?
In most cases, yes. Keeping your natural tooth preserves your bite and avoids the added cost and time of a bridge or implant later.
What should I eat after getting a root canal filling?
Soft foods and chewing on the opposite side for a day or so is a good idea while the local anesthesia wears off and any soreness settles.
