Gingival cyst - A small white bump has appeared beneath a tooth that underwent root canal treatment nine years ago?

Hello, Doctor.
The small bump is located on the upper right first molar.
This tooth underwent treatment for a cavity nine years ago, and the dentist indicated that the decay had reached the nerve, so a root canal treatment was performed, and a porcelain crown was placed for protection.
Three years ago, I experienced acute pain (with facial swelling), but an X-ray showed no signs of infection in the root area.
The dentist then suggested removing the crown and fabricating a new one.
However, the pain subsided on its own after three days, and since there was no pain afterward, I did not pursue any further treatment.
I have been regularly monitored every six months, and I get an X-ray once a year (as I am studying abroad).
The dentist has not mentioned any signs of inflammation.

Today, after drinking ginger soup, I noticed a distinct small white bump on my gum, located on the front (buccal) side of the molar, near the bottom part (very close to the top of the crown).
Currently, there is no significant pain (nor any pain when biting), but since I will be returning home in about two weeks, I would like to ask whether this type of cyst can be treated with anti-inflammatory medication (or oral ointment), or if I should wait to address it when I return home.
I have a habit of using dental floss and brushing my teeth daily, but I am prone to cavities.
Can I still use dental floss with this type of cyst? Thank you, Doctor.

Hello: It is recommended to wait until you return to your home country to have an X-ray taken to confirm the true condition of the cyst.
Oral anti-inflammatory medications or topical oral ointments can temporarily relieve discomfort and may prevent the cyst from worsening, but it is still advised to pursue definitive treatment for a chance at complete recovery.

More Info

Understanding gum cysts, particularly after a root canal treatment, can be crucial for maintaining oral health. Based on your description, it sounds like you may be experiencing a periapical cyst or a similar type of cyst that can develop in response to previous dental issues, particularly after root canal therapy.

What is a Gum Cyst?
A gum cyst, often referred to as a dental cyst, is a fluid-filled sac that can form in the gums or around the roots of teeth. These cysts can develop as a result of infection, inflammation, or even as a response to trauma. In your case, the history of root canal treatment and the previous acute pain episode suggest that there may have been some underlying issues that could have led to the formation of this cyst.

Symptoms and Diagnosis
You mentioned that you have a small white bump on your gums near the first molar, which is a common location for such cysts. While you do not currently experience pain, the presence of a cyst can sometimes indicate an underlying infection or inflammation, even if it is not symptomatic at the moment. Regular X-rays and dental check-ups are essential, as they can help identify any changes in the bone or surrounding tissues that may not be visible to the naked eye.

Treatment Options
1. Observation: Since you are not experiencing pain and have regular dental check-ups, your dentist may recommend monitoring the cyst for any changes. If it remains asymptomatic, it may not require immediate intervention.

2. Medication: While anti-inflammatory medications can help reduce swelling and discomfort, they do not treat the cyst itself. If you are considering taking anti-inflammatory medication or using topical treatments, it is best to consult with your dentist first, especially since you are planning to return home soon.

3. Surgical Intervention: If the cyst does not resolve on its own or if it becomes symptomatic, your dentist may recommend surgical removal. This typically involves excising the cyst and may require additional treatment to address any underlying infection.

Oral Hygiene Considerations
Maintaining good oral hygiene is crucial, especially when dealing with a cyst. You can continue to use dental floss and a toothbrush, but be gentle around the cyst area to avoid irritation. If you notice any increased discomfort or bleeding while cleaning, it may be wise to adjust your technique or consult your dentist for advice.

Conclusion
In summary, while the presence of a gum cyst can be concerning, it is essential to approach the situation with careful observation and professional guidance. Since you are returning home soon, it would be prudent to schedule an appointment with your dentist as soon as possible to evaluate the cyst and determine the best course of action. In the meantime, continue practicing good oral hygiene, and do not hesitate to reach out to your dentist if you have any concerns or if the cyst changes in size or becomes painful.
