Root Canal Therapy at Precision Dental Care
A root canal treats a tooth whose inner pulp — the soft tissue carrying the nerve and blood supply — has become infected or badly inflamed. Rather than removing the whole tooth, we open it, take out the infected tissue, clean and disinfect the canals that run down each root, and seal them so bacteria cannot get back in. The tooth stays where it is, still rooted in your jaw, still doing its job in your bite. That distinction matters: a natural tooth holds its neighbors in place and keeps loading the bone in a way no replacement quite reproduces, which is why saving one is almost always worth the appointment. With modern anesthesia and instruments, the treatment itself is about as comfortable as having a filling.
Signs You May Need One
Not every ache means a root canal, but these are worth having looked at quickly.
- A persistent toothache Particularly one that wakes you or throbs.
- Sensitivity to hot or cold that lingers Pain that stays after the stimulus is gone.
- Pain on chewing or biting Pressure on the tooth reproduces it.
- Swelling or tenderness in the gum Around one particular tooth.
- A darkened or discolored tooth Often a sign the nerve has died.
- A pimple-like bump on the gum A sinus draining an infection at the root.
Delay usually makes the outcome worse, not better — the infection spreads into the bone and the tooth becomes harder to save.
What to Expect
- Comfort first The tooth is numbed completely, and sedation is available if you want it.
- The infected pulp is removed We open the tooth and clear out the bacteria and debris.
- The canals are shaped and disinfected Each root canal is cleaned along its full length.
- The space is sealed Filled with a biocompatible material so nothing can re-enter.
- The tooth is restored A crown or filling brings back strength and appearance.
- One or two visits Most cases take 60 to 90 minutes and finish in a single appointment.
The Technology That Makes It Predictable
Curved and complex root anatomy is the usual reason a root canal fails, which is why we image before we start. A cone beam CT scan shows the number, shape and length of the canals in three dimensions, digital X-rays confirm progress during treatment, and the restoration that follows is made in our own lab. If the tooth cannot be saved, we will tell you plainly and talk through extraction and implant options. For a tooth that is hurting today, see emergency dental care.
The short answer
Root canal therapy treats a tooth whose inner pulp, the soft tissue carrying the nerve and blood supply, has become infected or badly inflamed. The infected tissue is removed, the canals inside each root are cleaned and disinfected, and they are sealed so bacteria cannot get back in. The natural tooth stays in place, and with modern anesthesia the treatment is about as comfortable as having a filling.
Root Canal Therapy FAQ
- Is a root canal painful?
- No, with modern anesthesia and instruments a root canal is about as comfortable as having a filling. The pain people associate with root canals is the infection, not the procedure, and the treatment is what ends it. The tooth is numbed completely before we begin, and sedation is available if you want it.
- Why not just take the tooth out?
- Keeping your own tooth maintains your bite, your chewing and the bone around it, which is why saving it is almost always worth the appointment. A natural tooth holds its neighbors in place and keeps loading the bone in a way no replacement quite reproduces. Extraction is a reasonable option, but it usually means replacing the tooth later. If the tooth cannot be saved, we tell you plainly and talk through extraction and implant options.
- How long does it take?
- Most root canals take 60 to 90 minutes and can be completed in one visit, though some cases need two. That time covers removing the infected pulp, cleaning and disinfecting each canal along its full length, and sealing the space. A crown or filling then restores the tooth.
- Will I need a crown afterwards?
- Usually, yes, a crown is needed afterward, particularly on back teeth. A treated tooth becomes brittle, and a crown protects it from fracturing. The restoration that follows is made in our own lab.
- How long does a root canal last?
- With proper care, a root-canal-treated tooth can last a lifetime. Once the canals are sealed with a biocompatible material, bacteria cannot get back in, and the tooth stays rooted in your jaw doing its job in your bite. A crown or filling brings back its strength and appearance.
- What if I am nervous about it?
- If you are nervous, tell us when you book and we will plan around it. We offer sedation and will explain each step before it happens. The tooth is numbed completely first, and with modern anesthesia the treatment is about as comfortable as having a filling.
- Will insurance cover a root canal?
- Most insurance plans cover part or all of a root canal. We verify your benefits and give you the estimate in writing first. That way you know the cost before treatment begins.
- What happens if I wait?
- If you wait, the infection spreads into the surrounding bone. That can mean losing the tooth, and in some cases a more serious infection. Delay usually makes the outcome worse, not better, because the tooth becomes harder to save.
- Can you treat teeth with curved or complex roots?
- Yes, we treat teeth with curved and complex roots, and we image them in 3D with a cone beam scan first. The scan shows the number, shape and length of the canals before we begin. Complex root anatomy is the usual reason a root canal fails, which is why that imaging comes first, and digital X-rays confirm progress during treatment.
- What should I eat afterwards?
- Stick to softer foods for the first few days after a root canal. We give you full aftercare instructions before you leave. Until the tooth has its crown, it is brittle, so go easy on it when chewing.
