[Health Column] Is Root Canal Treatment Absolutely Necessary? Things to Check First When a Cavity Is Deep

 

 

I went to get a cavity treated. The cavity is deep, so I think I need a root canal. Many of you were likely taken aback to hear that. It is only natural to wonder if it is absolutely necessary or if there are other options, given that you are suddenly told to remove the nerve when you have no pain.

 

Even in the examination room Does the tooth die if I get a root canal? , If a cavity is large, do I always have to get a root canal? I get the same question often.

 

Today, we will look at what root canal treatment is, when it is absolutely necessary, and When can you first check if the nerve can be preserved, even if the cavity is deep? I will explain it in order.

 

1️⃣ What exactly is a root canal?

 

It is commonly called 'nerve treatment,' but the official name is Root canal treatment It is. The inside of the tooth contains nerves and blood vessels. 'size' There is a tissue called the pulp, and if bacteria enter the pulp due to deep cavities or trauma such as a broken tooth, inflammation occurs.

 

Root canal treatment is a procedure that involves removing the inflamed or infected pulp, thoroughly disinfecting the inner passage (root canal), and then filling and sealing it with other materials. Even in the medical information from Seoul National University Hospital, root canal treatment is not so much about 'treating' the nerve, but rather, A treatment that preserves the tooth by removing the pulp and filling the space. He explains.

 

 

Treatment is usually given at intervals of a few days to a week. Proceed in 2 to 3 sessions Also, if the molar has multiple roots or the inflammation is severe, you may need to visit the clinic multiple times.

 

To summarize, root canal treatment is Treatment to save and use teeth without extraction However, since a tooth from which the nerve has been removed becomes that much weaker, it is advisable to check the possibility of saving the nerve first if possible.

 

2️⃣ When is root canal treatment necessary?

 

Just because a cavity has reached the nerve does not mean that root canal treatment is necessary. The important thing is Whether the nerve inside the tooth is in a condition where recovery is possible, or if it is already in a state where recovery is difficult. no see.

 

According to data from the Department of Dentistry at Asan Medical Center, if the sensitivity to cold water is temporary, it is often reversible pulpitis, so root canal treatment is not performed immediately. On the other hand If you feel pain in hot water In many cases, it is difficult to recover from pulpitis (irreversible pulpitis), so root canal treatment may be necessary.

 

 

 

However, it cannot be determined solely by symptoms. There are cases where the nerve is already damaged despite almost no pain, and conversely, cases where recovery is possible even with symptoms. Therefore Decision made by reviewing the X-ray examination and the test checking the tooth nerve's response together. do.

 

3️⃣ Do I always have to get a root canal if the cavity is deep?

 

That is not necessarily the case. Even if the cavity has progressed close to the nerve, if the nerve is still healthy, a treatment can be attempted first to preserve it by carefully removing the cavity and covering it with a protective material. Lifestyle dental treatment It is called...

 

In a 2019 statement, the European Endodontic Society stated that when treating deep cavities Preserving the nerve (pulp) in a healthy, living state It was presented as a goal. The American Academy of Endodontics also supported vital pulp treatment as a treatment option in its 2021 statement, which preserves nerves damaged by cavities or trauma.

However, this treatment is not possible in all cases, and results vary from person to person. If pain develops over time after treatment or the nerve does not recover, you may eventually need to proceed with root canal treatment. Therefore Accurate diagnosis before treatment and follow-up observation after treatment This must be accomplished together.

 

4️⃣ Conversely, are there teeth that are difficult to save?

 

The principle is to preserve natural teeth as much as possible. However, keeping all teeth at all costs is not the answer.

 

Teeth function properly only when held in place by the gum bone. As a periodontist, when examining teeth, I consider not only the depth of the cavity but also, How much gum and alveolar bone supporting that tooth remains We also check this together. By examining the periodontal probing examination, which measures the depth of the gum pocket, along with the X-ray, we can determine to some extent whether the tooth is unlikely to last long even after root canal treatment.

 

 

If the root is fractured vertically or the tooth is significantly loose due to the loss of most of the gum bone, the prognosis may be poor even after root canal treatment. Forcing the retention of such a tooth can cause inflammation to affect the surrounding gum bone and adjacent teeth, and may also disrupt the overall chewing balance.

 

Saving teeth that can be saved until the very end, and honestly explaining the reasons for teeth that need to be trimmed. I believe that accurately distinguishing between the two is the key to diagnosis.

 

5️⃣ How should I care for my skin after root canal treatment?

 

Just because root canal treatment is finished does not mean the treatment is completely finished. In teeth that have undergone root canal treatment, not much of the tooth remains. The chewing force or resistance to impact is significantly reduced.

 

According to data from Seoul National University Hospital and Seoul Asan Hospital, after nerve treatment Restorative treatment that covers the tooth like a crown We advise that you must do this. If you continue to use the tooth without restoration and it breaks, there is a possibility that extraction may be necessary.

🔹 During the treatment period
Since it is temporarily blocked, it is best to chew hard or tough foods on the opposite side.

 

🔹 After finishing treatment
If pain or discomfort persists for a significant period, do not simply endure it; you should re-examine the cause.

 

🔹 Regular checkups
Teeth that have undergone root canal treatment lack nerves, so even if cavities develop again, it is difficult to detect them through sensitivity. Checking one's condition through regular checkups even when not sick This is a method to use your teeth for a long time.

 

 

💬 Frequently Asked Questions (FAQ)

 

Q1. Does a tooth die if I get a root canal?

A1. Since root canal treatment removes the nerve and blood vessels inside the tooth, the tooth can no longer feel hot or cold sensations. However, the tooth root remains attached to the gum bone, so chewing function can be maintained with proper restoration and care.

 

Q2. Is root canal treatment very painful?

A2. Since root canal treatment is performed under local anesthesia, pain during the procedure is mostly controlled. You may experience a dull or throbbing sensation when chewing for a few days after treatment, but this usually subsides gradually. However, if the pain worsens or persists for a long time, please inform your medical team.

 

Q3. Is it necessary to get a crown after root canal treatment?

A3. Teeth that have undergone root canal treatment have a small remaining portion and are weakened, making them prone to breakage; therefore, restorations that cover the tooth, such as crowns, are usually necessary. However, in cases where chewing forces are less applied, such as with front teeth, and there is sufficient remaining tooth structure, other methods may be considered. Please consult with us to determine the best approach based on the condition of your tooth.

 

Q4. I received treatment to preserve the nerve; is it possible that I might need root canal treatment later?

A4. That is possible. Nerve-preserving treatment is attempted based on the judgment that the nerve can recover, but if the nerve does not recover over time or pain develops, you may need to proceed with root canal treatment. Even after treatment, it is advisable to monitor your reaction to hot and cold temperatures and any changes in pain, and to have your progress checked at scheduled times.

 

Q5. How do I decide whether to have a root canal or to extract the tooth and get an implant?

A5. The principle is to preserve natural teeth if they can be saved. However, if the root is fractured or the gum bone has significantly eroded, making it difficult to use the tooth for a long time, extraction followed by other treatments may need to be considered. We recommend that you make a decision after examining not only the depth of the cavity but also the condition of the gums and gum bone, and after fully hearing the advantages and disadvantages of each method.

 

🎯 Wrapping up

 

Root canal treatment is a procedure designed to save a tooth without extraction. However, not all deep cavities require root canal treatment, and If the nerve is at a stage where recovery is possible, consider nerve-preserving treatment first. You can try it.

 

Conversely, if the nerve is already in a state where recovery is difficult, not delaying root canal treatment is the way to preserve the tooth; however, if the gum bone has also collapsed, forcing the tooth to remain intact can actually place a burden on surrounding teeth.

 

Ultimately, what matters more than what treatment you receive is, Knowing exactly what stage the condition of my tooth nerves and gums is currently at Treatment results may vary depending on the individual, so please make a decision after consulting thoroughly with medical professionals based on your test results.

 

Not performing unnecessary treatments, and not overlooking essential ones. I believe that the starting point of such judgment is an accurate diagnosis. 🦷
