Can a cyst be treated without root canal therapy?

I would like to consult with a doctor.
Last year, I had a cavity in my upper right first premolar that was filled.
At that time, I was informed that the cavity was quite deep, and if necessary, I might need a root canal later on.
For the past six months, the tooth has been very sensitive, and I have to brush with warm water.
One day, I suddenly experienced sharp pain that lasted for two days, but then it subsided, and I could eat hot and cold foods without any issues.
After researching online, I learned that the pulp might be necrotic and that I might not feel any pain.
Since I didn't feel any pain, I didn't pay much attention to it.
However, later on, I noticed a swelling next to the tooth, which also didn't hurt and didn't affect my eating.
Still concerned, I consulted with the dentist, who suggested that I might need a root canal and advised me to discuss it with my orthodontist for further evaluation.

Currently, I am undergoing orthodontic treatment, and the orthodontist examined me and mentioned that the filling was done on the dental nerve, and the deep cavity likely caused the current cyst.
It seems that a root canal treatment is necessary.
I have a couple of questions:
1.
Is it possible to avoid a root canal and simply perform surgery to remove the cyst? The swelling causes a pressure sensation when I press on it, which is why I am concerned.
Otherwise, it doesn't affect me at all.
However, I know that a cyst can be like a ticking time bomb, and if left untreated, it could worsen.
I want to know if it's feasible to just remove the cyst without doing a root canal, as I consider the root canal to be a last resort.
2.
Since a root canal involves creating an opening from the occlusal surface of the tooth to remove the dental nerve, and the cyst is currently located next to the gum, if I only perform a root canal, will the swollen cyst resolve on its own? I am worried that even after the root canal, the cyst might still be there, and I would end up needing surgery to remove it anyway.
Wouldn't it be better to just remove the cyst from the beginning?

When it comes to treating dental cysts, particularly those associated with deep cavities and potential pulp necrosis, the decision between performing a root canal therapy (RCT) or simply excising the cyst can be complex. Here’s a detailed exploration of your questions regarding the management of dental cysts without resorting to root canal therapy.

1. Can a cyst be treated without root canal therapy?
In some cases, it is possible to treat a dental cyst without performing a root canal. If the cyst is not causing significant symptoms and is not associated with an active infection, a dentist may opt to monitor the cyst over time. However, if the cyst is symptomatic or if there is a risk of it becoming infected, surgical intervention may be necessary. This could involve a procedure known as cystectomy, where the cyst is surgically removed. It is important to note that while removing the cyst may alleviate some symptoms, it does not address the underlying issue of pulp necrosis if the tooth's nerve is already compromised. Therefore, while you can have the cyst removed, if the tooth is non-vital (dead), root canal therapy may still be required to prevent future complications.

2. Will the cyst shrink or resolve on its own after a root canal?
After a root canal procedure, if the tooth is treated effectively, the inflammation associated with the cyst may decrease, and the cyst itself may shrink over time. However, this is not guaranteed. The success of this approach depends on several factors, including the size of the cyst, the presence of infection, and the overall health of the tooth. If the cyst is large or if there is significant bone loss, additional treatment may be necessary to fully resolve the issue. In some cases, if the cyst does not resolve after root canal therapy, a separate surgical procedure to remove the cyst may still be required.

In summary, while it is possible to treat a cyst without performing a root canal, this approach may not address the underlying issues if the tooth's pulp is necrotic. If the cyst is causing discomfort or has the potential to lead to further complications, it is advisable to consider root canal therapy as a definitive treatment option. Consulting with both your general dentist and an endodontist (a specialist in root canal therapy) can provide you with a comprehensive understanding of your options and help you make an informed decision regarding your dental health.
Ultimately, the best course of action will depend on the specifics of your situation, including the health of the tooth, the nature of the cyst, and your overall dental health. Regular follow-ups and imaging may also be necessary to monitor the situation and ensure that any treatment you choose is effective.
