If your dentist has told you that you need a root canal, your first reaction was probably one of two things: panic about the pain or panic about the cost. Both are valid concerns, and this guide addresses them honestly.
Root canal treatment has a reputation that is far worse than the reality, and many Lagos patients delay or avoid it entirely because of misinformation. By the end of this, you will know exactly what the procedure involves, how much it costs in Lagos, and what to expect from start to finish.
What Is Root Canal Treatment?
Root canal treatment is a dental procedure that removes infected or damaged tissue from inside a tooth, cleans the space out, and seals it to prevent further infection. The goal is to save the tooth rather than remove it.
To understand why this is sometimes necessary, it helps to know a little about tooth structure.
What Is Actually Inside Your Tooth
Beneath the hard outer layers of your tooth, the enamel and the dentine, there is a soft inner chamber called the pulp. This pulp contains nerves, blood vessels, and connective tissue. It is what makes your tooth sensitive to temperature and pressure.
When the pulp becomes infected or inflamed, whether from deep decay, a crack, or repeated dental work on the same tooth, it cannot heal on its own. The infection spreads, the pain intensifies, and left untreated, it can develop into a dental abscess or spread to surrounding bone and tissue.
Root canal treatment removes the infected pulp, eliminates the source of pain, and preserves the outer structure of the tooth.
What Causes a Tooth to Need Root Canal Treatment?
Root canal is not something that happens randomly. It is almost always the result of a dental problem that was either unavoidable or left unaddressed for too long. Some of the common causes of root canal problems are:
1. Deep Decay From Untreated Cavities
2. Cracked or Fractured Teeth
3. Repeated Dental Procedures on the Same Tooth
4. A Tooth Injury
Deep Decay From Untreated Cavities
This is the most common cause. A cavity that is caught early only needs a dental filling. A cavity that is ignored for months or years eventually reaches the pulp. At that point, a filling is no longer enough.
Many Lagosians visit the dentist only when the pain becomes unbearable. By then, what could have been a simple procedure had progressed into something more involved. The tooth is not to blame. The delay is.
Cracked or Fractured Teeth
A crack in a tooth, even one too small to see, creates an opening for bacteria to reach the pulp. This can happen from biting down on something hard, a physical impact, or years of grinding teeth at night.
Hard foods are a contributing factor here: chin-chin, hard candy, and using teeth to open bottles are habits that many people do not connect to dental problems until one occurs.
Repeated Dental Procedures on the Same Tooth
When a tooth has had multiple fillings or procedures over the years, the pulp can become irritated and inflamed even without a visible infection. Eventually, root canal treatment becomes necessary to address the accumulated stress on the tooth.
A Tooth Injury
Sometimes a tooth sustains trauma that damages the pulp without cracking or breaking the outer tooth. This is common in children and young adults from contact sports or falls. The damage may not show up immediately, but it can lead to pulp death over time. This is part of why family dentistry should be part of every family in Lagos.
How Root Canal Treatment Works: Step by Step
Many patients are anxious about this procedure because they do not know what to expect. Walking through the process takes away most of that fear.
Step 1: Examination Before the Procedure
Your dentist will examine the affected tooth to assess the extent of the infection and the shape of the root canals. This is what guides the entire treatment plan.
Step 2: Numbing the Tooth
Before anything else, a local anaesthetic is administered to numb the tooth and the surrounding area completely. Most patients are surprised by how little they feel once the area is numb. The injection itself may cause a brief sting, but after that, discomfort is minimal. This is the part most people fear the most, and it is rarely as bad as expected.
Step 3: Cleaning Out the Infected Pulp
Once the tooth is numb, your dentist creates a small opening through the top of the tooth to access the pulp chamber. Tiny instruments are used to carefully remove the infected pulp and clean the root canals thoroughly. The canals are then shaped to prepare them for filling.
Step 4: Filling and Sealing the Canals
The cleaned canals are filled with a biocompatible material called gutta-percha, which seals the space and prevents bacteria from re-entering. A temporary or permanent filling is then placed over the opening.
The Crown: Why You Will Likely Need One After
This is something many patients are not told upfront, and it causes unnecessary surprise when the bill arrives.
After root canal treatment, the tooth loses its internal blood supply and becomes more brittle over time. A dental crown is placed over the treated tooth to protect it from cracking under the pressure of everyday chewing. Without a crown, a root-canal-treated tooth is vulnerable to fracture, which could mean losing the tooth entirely after all the work done to save it.
The crown is not optional. It is a necessary part of completing the treatment properly.
Is Root Canal Treatment Painful?
The short answer is: not the way most people expect.
The procedure itself is performed under local anaesthesia, which means the tooth and surrounding tissue are completely numb. Most patients feel pressure and movement but not pain. Many describe it as similar to having a filling done.
The reputation for being painful comes from an era before modern anaesthesia techniques. It has largely not caught up with the reality of what the procedure feels like today.
But what do you feel after the procedure?
Once the anaesthetic wears off, it is normal to experience some soreness and sensitivity around the treated tooth for a few days. This is your body responding to the procedure, not a sign that something went wrong. Over-the-counter pain relief like ibuprofen or paracetamol is usually enough to manage it.
If the pain is severe, worsening after a few days, or accompanied by swelling, contact your dentist. That warrants a review.
How Much Does Root Canal Treatment Cost in Lagos?
This is the section most people scroll straight to, so here is a direct answer.
Root canal treatment cost ranges from ₦100,000 to ₦250,000, depending on several factors. This is for the root canal procedure itself. If a dental crown is required afterward, which it usually is, that adds ₦60,000 to ₦150,000 to the total cost.
What Determines the Root Canal Treatment Cost?
Which tooth is being treated is one of the biggest factors. Front teeth with one or two canals cost less than molars with three or four canals. More canals mean more work and more time in the chair.
The severity of the infection matters too. A straightforward case with no abscess is quicker and less complex than one where the infection has spread and requires additional management before the root canal itself can be completed.
The clinic and the dental team also affect pricing. A clinic with experienced dentists, proper X-ray equipment, and clinical-grade materials will charge more than an unequipped setup. That difference in cost reflects a real difference in the quality and safety of your care. We have all this equipment at Dr. Reach Dental Clinic.
Root Canal Cost vs. Extraction and Replacement
Many patients consider pulling the tooth because it seems cheaper. And the extraction alone is less expensive, typically between ₦30,000 and ₦150,000 in Lagos, depending on complexity.
But a missing tooth rarely stays a missing tooth without consequences. If you decide later to replace it with a dental implant, which is the closest thing to a natural tooth, you are looking at ₦400,000 to over a million naira for that single implant in Lagos. A dental bridge is less expensive but involves grinding down the neighbouring healthy teeth.
When you factor in the full picture, root canal treatment followed by a crown is often more cost-effective than extraction and replacement, not to mention better for your long-term oral health.
What to Do After Root Canal Treatment
For the first 24 to 48 hours, avoid chewing on the treated side until your permanent filling or crown is placed. Stick to soft foods: pap, mashed yams, soft rice, or anything that does not require significant biting force on that tooth. Avoid very hot drinks and anything extremely cold or sweet, as the tooth may still be sensitive.
Do not skip the pain medication your dentist recommends, even if you feel fine immediately after. Managing inflammation early makes recovery more comfortable.
When to Be Concerned
Some soreness in the days following treatment is normal. What is not normal is pain that gets progressively worse after day three, visible swelling around the jaw or face, fever, or pus near the treated tooth. Any of these symptoms means you should contact your dentist promptly rather than waiting it out.
Long-Term Care
A root-canal-treated tooth with a crown on it can last many years with proper care. Brush twice daily, floss regularly, and keep up with your routine dental checkups. The tooth no longer has a nerve, so it will not warn you with pain if something goes wrong, which is exactly why regular dental reviews matter even more after treatment.
Frequently Asked Questions
In Lagos, root canal treatment typically costs between ₦80,000 and ₦300,000, depending on which tooth is involved, the complexity of the infection, and the clinic.
During the procedure, no. The tooth is completely numbed with local anaesthesia before anything starts. Most patients feel pressure but not pain. After the procedure, some soreness is normal for a few days and is manageable with standard pain relief.
In most cases, a root canal is the better choice. Your natural tooth is stronger than any replacement, and keeping it preserves your jawbone and the alignment of surrounding teeth. Extraction may seem simpler upfront, but if you factor in the cost and complexity of replacing the tooth properly afterward, the root canal is usually the more sensible long-term investment.
Yes, though it is not common when the procedure is done properly, and the tooth is restored with a crown. Reinfection can occur if the seal breaks down, the crown is delayed or not placed at all, or if new decay develops around the tooth. This is why aftercare and regular dental checkups matter even after a successful root canal.
