When performing root canal therapy in Charlotte, NC, we rely on the latest technologies for a straightforward and painless procedure. Rather than hand tools, our dentist uses rotary endodontics, which is more precise and less jarring than previous methods.
Why Do I Need a Root Canal and How Does it Work?
You need root canal therapy if you have a deep tooth infection, specifically when the infection penetrates the tooth’s canal. Untreated tooth decay and injuries to the tooth may result in a deep tooth infection.
If you have a root infection, you’ll likely have a toothache or increasing tooth sensitivity. You may also notice swelling, a blister on the gum, and tooth discoloration. It’s crucial to see your dentist. The pain will only worsen, and you may lose the tooth without intervention.
Step-by-Step: How Root Canal Therapy Works
Root canal therapy is performed under local anesthesia, so you’ll be completely numb and comfortable throughout the procedure. Most patients report little to no pain — only mild pressure and movement during treatment.
Here’s what to expect during the process:
1. Diagnosis and Numbing
Your dentist will examine the tooth and take digital X-rays to assess the extent of infection. Once confirmed, local anesthesia is administered to fully numb the area.
2. Accessing the Infected Pulp
A small opening is made in the top of the tooth to reach the infected pulp chamber and root canals. This step is performed with precision using rotary endodontic instruments.
3. Removing Infection and Cleaning Canals
The infected or inflamed pulp is carefully removed, and the canals are thoroughly cleaned and disinfected to eliminate bacteria. This step is critical to prevent reinfection.
4. Shaping and Filling the Canals
After cleaning, the canals are shaped and sealed with a biocompatible material called gutta-percha. This seals off the tooth from future bacterial invasion.
5. Sealing and Restoring the Tooth
A temporary filling is placed to protect the tooth while it heals. In most cases, a dental crown is recommended a week or two later to restore strength, function, and appearance — especially for molars and heavily used teeth.
What Happens After Root Canal Therapy?
Recovery from root canal therapy is typically quick and uncomplicated. You might experience mild tenderness for a day or two, which is easily managed with over-the-counter pain relief. Most patients return to normal activities immediately after the procedure.
Once the permanent crown is placed, your tooth will function just like a natural one. With good oral hygiene and regular dental visits, a tooth treated with a root canal can last a lifetime.
