The Truth About Root Canals: What to Expect and How They Save Your Teeth

The Root Canal Fear Factor: Separating Myth from Reality

If you’ve ever heard someone say a root canal is worse than a toothache, you’ve encountered one of dentistry’s most persistent myths. The truth is the opposite. A root canal relieves the pain of an infected or dying tooth. It doesn’t cause it.

The reputation exists partly because of history. Root canal treatment decades ago was uncomfortable and involved longer procedures and rougher instruments. Modern technology has transformed the experience entirely. Today, root canal therapy is a standard procedure that alleviates pain while preserving your natural tooth structure. At Bonin Dental Care in Windsor, we see patients come in anxious about root canals every week. By the time they leave, most understand that the infection inside their tooth was the real problem, and that the treatment is what ends it.

What Actually Happens During a Root Canal

Understanding the clinical reality makes most anxiety disappear. Here’s a step-by-step walkthrough of what occurs during root canal therapy.

One thing to know up front: Dr. Bonin is a general dentist, and he refers every root canal to a trusted endodontist. An endodontist is a specialist who does nothing but root canals, all day, every day. Dr. Bonin’s job is to find the problem, get you out of pain, hand the case to the right specialist with the imaging already done, and then rebuild and crown the tooth once the root canal is finished. More on how that works below.

Step One: Diagnosis and Anesthesia

The process begins with a careful examination and typically an X-ray to confirm the diagnosis. Dr. Bonin will assess whether the tooth truly needs root canal therapy or whether another treatment might work. Once it’s confirmed and he’s referred you to the endodontist, the treatment itself starts with local anesthesia. You’ll feel slight pressure during injection, then complete numbness within a few minutes. The area around your tooth will feel thick and tingly, which means you won’t feel pain during the procedure.

Step Two: Isolation and Access

To work safely and keep the tooth dry, the endodontist places a rubber dam around it. This rubber sheet isolates the tooth and protects you from swallowing water or instruments. Then the endodontist creates a small access opening in the crown of the tooth to reach the pulp chamber inside. This opening is precise and only as large as necessary to complete the job.

Step Three: Pulp Removal and Cleaning

Inside each tooth is the pulp, a bundle of blood vessels and nerve tissue that extends from the crown down through canals inside the tooth roots. When a tooth becomes infected or severely damaged, this pulp dies or becomes infected and must be removed. The endodontist uses specialized instruments called files to gently remove the dead or infected pulp tissue and then clean the inside of the tooth thoroughly.

This is the most important part of the procedure. The canals must be completely cleaned and shaped so they can be sealed properly. The irrigation solutions used during this phase disinfect the canals. You’ll hear a distinct sound as the instruments work, and you’ll feel vibration, but little to no discomfort.

Step Four: Shaping and Disinfection

Once the pulp is removed, the canals are gradually shaped using increasingly larger files. This creates a space that can be properly filled. Throughout this process, the canals are flushed with antimicrobial solutions to eliminate bacteria and prevent future infection. This step typically takes longer than removal and is critical to the long-term success of the procedure.

Step Five: Filling and Sealing

Once the canals are cleaned, shaped, and disinfected, they must be sealed. An inert biocompatible material called gutta-percha, a rubber-like substance, is used to fill the canal space. It’s combined with an adhesive sealer to ensure a complete, three-dimensional seal. The access opening in the crown is then filled with a tooth-colored restoration, often a composite resin that bonds to the remaining tooth structure.

The whole process typically takes between one and two hours, depending on the complexity of the tooth and how many canals it contains. Front teeth usually have one canal and are faster. Molars often have three or four canals and take longer.

How Dr. Bonin Handles Root Canal Cases

Dr. Scott Bonin is a general dentist, and he refers all root canal treatment to a trusted endodontist here in Sonoma County. That is a deliberate choice, not a gap. An endodontist has years of additional training devoted entirely to the inside of the tooth and works with microscopes, advanced imaging, and instruments built for exactly this. When your tooth is on the line, you want the person who performs this procedure every single day.

What Dr. Bonin does is just as important, and it’s the part patients tend to underestimate.

He finds the problem. Root canal cases are often misdiagnosed. Pain moves, it refers, and it lies. Dr. Bonin examines the tooth, takes the X-rays and any imaging needed, tests the nerve, and determines whether the tooth actually needs root canal therapy or whether something simpler explains your symptoms.

He gets you out of pain, usually the same day. You do not have to wait for a specialist appointment to stop hurting. Pain management and, when infection is present, antibiotics start at Bonin Dental Care.

He makes the referral and sends the file. Dr. Bonin refers you to an endodontist he knows and trusts, forwards your imaging and diagnostic notes, and stays in communication throughout. You are not handed a phone number and left to figure it out.

He restores the tooth afterward. This is the step that decides whether the tooth lasts. A tooth that has had a root canal is hollow and brittle, and it needs a properly designed crown to survive years of chewing. Dr. Bonin’s continuing education through Spear Education is focused on restorative and reconstructive dentistry, which is precisely the skill set that matters when it comes time to rebuild the tooth and seat that crown.

At Bonin Dental Care, Dr. Bonin prioritizes patient comfort and transparency. He’ll explain what he sees on X-rays, discuss why the tooth needs treatment, and walk you through the procedure and the referral before anything happens. This reduces anxiety considerably because understanding what’s happening removes a lot of fear.

When to Save a Tooth Versus Extract It

Not every tooth needs a root canal, and not every infected tooth can be saved. Dr. Bonin evaluates several factors to determine the best course of action.

A tooth is typically a candidate for root canal therapy if it has a restorable crown structure, adequate bone support around the root, and no vertical fractures that extend deep into the root. The tooth must also have enough length and strength to support a restoration afterward.

If a tooth is severely broken below the gum line, has extensive bone loss, or is too compromised to restore, extraction may be the better choice. Sometimes a tooth that previously had a successful root canal fails years later due to a new fracture or breakdown, and extraction becomes necessary.

The decision between saving and extracting has long-term consequences. Your natural tooth, even one that has had root canal therapy, typically outlasts other options. A root canal-treated tooth is weaker than a vital tooth and usually needs a crown to protect it. But that crown can last 15, 20, or more years. In contrast, if you extract a tooth, you then face the expense and time of replacing it with an implant, bridge, or denture. Extraction also causes progressive bone loss in the jaw at that location.

Dr. Bonin always favors saving your natural tooth when it’s possible to do so successfully. The longevity and integration of your natural tooth with your jaw, even a treated one, remains the gold standard in dentistry.

What Recovery Looks Like

Recovery from a root canal is generally straightforward and faster than many patients expect.

The Day of Treatment

Once the anesthesia wears off, you may feel some sensitivity or mild discomfort. This is normal. Over-the-counter pain relievers like ibuprofen or acetaminophen typically manage any discomfort. Many patients report they feel relief just from having the infection removed, so any discomfort is usually less than they experienced before the procedure.

Avoid chewing on the treated tooth until it receives a permanent crown. The tooth is more fragile at this point, and chewing could cause problems. Stick to soft foods and chew on the opposite side of your mouth.

The Following Days

Most patients return to their normal activities within a day. Some experience slight sensitivity to temperature for a few days as the tooth adjusts. This sensitivity gradually diminishes. The area might feel slightly tender to the touch, similar to how a tooth feels slightly sore after a cleaning, but this resolves quickly.

Sleep well the night after treatment. Your body heals while you rest. Some patients prefer to take pain medication before bed to prevent any discomfort from waking them.

Follow-Up Care

You’ll come back to our office after the root canal is complete so Dr. Bonin can place a permanent crown on the tooth. This typically happens within two to four weeks. The temporary filling placed at the end of the root canal protects the tooth in the interim, but it’s not as strong or long-lasting as a permanent crown.

The crown serves an essential function. A root canal-treated tooth becomes more brittle over time because it no longer has a blood supply. A crown provides protection and reinforces the tooth so it can function normally for decades.

How Long Will the Tooth Last

This is the question every patient asks, and it deserves an honest answer.

Root canal therapy has a success rate of approximately 85 to 90 percent on the first treatment. That means the tooth remains functional and comfortable for many years. In fact, most root canal-treated teeth last as long as natural teeth with good oral hygiene and appropriate restoration.

The longevity depends on several factors. A tooth with a well-fitting crown and good oral hygiene lasts much longer than one without. A tooth in the back of your mouth that bears significant chewing force may have a shorter lifespan than a front tooth. A tooth that suffered trauma or had a large cavity beforehand may not last as long as one with a smaller problem.

Years or even decades after a successful root canal, the tooth may need re-treatment if new problems develop. This might happen if the crown becomes damaged and bacteria re-enter the tooth, or if a new cavity forms near the crown line. Re-treatment is possible and typically successful, though it’s more complex than the first treatment.

Some patients ask whether they should extract a tooth prophylactically rather than treat it with root canal therapy. Generally, this is not advisable. Why remove a functional tooth today to prevent a hypothetical problem tomorrow? If the root canal is successful, you keep your tooth. If it fails, you can still extract it at that time.

When to Seek a Second Opinion or Specialist Referral

Occasionally, a patient with a root canal recommendation wants a second opinion. This is completely reasonable, and Dr. Bonin respects the desire to verify a diagnosis.

If another dentist recommends root canal therapy for your tooth, ask them to explain their reasoning. Are there specific radiographic findings suggesting infection or damage? Is there a periapical lesion (a dark area at the root tip on X-ray indicating bone loss)? Are you experiencing symptoms like pain, discoloration, or swelling? A good explanation should make sense to you and address your concerns.

If you’re uncertain about a recommendation, a consultation with an endodontist (a specialist in root canal therapy) is a reasonable next step. Endodontists spend extra years in advanced training and perform root canals daily. They have access to advanced imaging and specialized instruments. They can confirm or refute whether treatment is necessary and explain your options clearly.

Because Dr. Bonin refers every root canal case to an endodontist anyway, you get that specialist opinion as a matter of course. He is not the one performing the procedure, so he has no reason to talk you into one. His only interest is an accurate diagnosis and a tooth that lasts.

Cost Considerations Without Breaking Your Budget

Root canal therapy requires a significant time investment and specialized expertise, which is reflected in the cost. We understand this is an important consideration, and we would rather you hear the whole picture up front than get surprised halfway through.

A root canal case involves two bills, not one. The endodontist quotes and bills you for the root canal itself, since that is the office performing it. Bonin Dental Care quotes and bills for the diagnosis, the emergency visit, and the crown or restoration that goes on afterward. Nobody enjoys hearing that, but knowing it in advance is better than discovering it later.

What we can do is make sure you are not guessing. Dr. Bonin will tell you what the restorative side costs at our office, file your insurance claims for our portion as a courtesy, and give you a realistic range for what the endodontist is likely to charge so you can plan for the whole case. Root canal therapy is a standard covered service under most dental plans, though coverage varies, and the endodontist’s office will verify your benefits for their portion.

If you don’t have insurance or if your plan has limitations, financing options may be available for the restorative work we provide. We can discuss what is available and the application process during your consultation.

It’s helpful to compare the cost of root canal therapy plus a crown to the cost of extraction plus implant, bridge, or denture. While root canal treatment costs something, the alternative replacements often cost more and involve ongoing maintenance. Your natural tooth, even one that’s been treated, is almost always the most economical long-term choice.

Frequently Asked Questions About Root Canals

Does a root canal hurt?

No. Local anesthesia completely numbs the tooth and surrounding area before treatment begins. You’ll feel pressure and vibration as the dentist works, but little to no discomfort. Any discomfort after the procedure is typically mild and manageable with over-the-counter pain relievers. The infection itself usually hurts more than the treatment does.

How long does a root canal take?

Most root canals take between 45 minutes and two hours. Front teeth with a single canal tend to be faster. Back teeth with multiple canals take longer. Teeth with complications may require additional time. Your dentist will give you a time estimate after examining your tooth.

Can I return to work after a root canal?

Yes, most people return to their regular activities the same day. You might prefer to schedule the appointment when you don’t have demanding activities planned afterward. Plan to avoid chewing on the treated tooth and take pain medication if needed, but you can work normally.

What’s the difference between a root canal and an extraction?

A root canal removes the infected or damaged pulp inside the tooth while preserving the tooth structure. An extraction removes the entire tooth. After extraction, you need to replace the tooth with an implant, bridge, or denture. Keeping your natural tooth is almost always the better option if it can be saved.

Can a tooth that had a root canal get a cavity?

Yes. A root canal-treated tooth can develop a new cavity if bacteria re-enter through a gap between the crown and tooth, or if a new cavity develops on the surface. This is why good oral hygiene, regular checkups, and maintaining a good crown fit are important after root canal therapy.
