Apical Cysts: Should You Worry After Years of No Symptoms? - Dentistry

Apical cyst


Hello, doctor.
About five years ago, I discovered a pus-filled cyst on my upper jaw and visited a dentist at Taipei Veterans General Hospital, who diagnosed it as an apical cyst.
Approximately twenty years ago, I fell and hit one of my teeth.
At that time, I didn't think much of it as there was only a minor surface crack.
However, the X-ray later showed a large dark shadow at the root of that tooth, and the dentist recommended root canal treatment, after which we would monitor whether the shadow (which he said was bone) would decrease in size.
After several sessions of root canal treatment, a follow-up six months later showed that the shadow had significantly reduced.
After another six months, I had another follow-up (or maybe two; I can't remember), and I recall that the shadow seemed to be nearly gone, and I couldn't feel the cyst anymore.
The dentist mentioned he might be leaving the practice and advised me to schedule a follow-up myself in six months.
However, I became pregnant and gave birth, so I didn't follow up after that.
During that time, I did visit other hospitals to have my wisdom teeth extracted, and they took a full mouth X-ray, where the dentist noted that there was a screw in that tooth, but he didn't mention the dark shadow.
I'm wondering if it might have disappeared.
Now, it has been about four years since my last follow-up, and there have been no unusual symptoms or discomfort in the area of the cyst.
However, I have become more health-conscious since giving birth, and after reading some information about oral cancer online yesterday, I became quite anxious.
I suddenly remembered my previous treatment for the apical cyst and would like to ask the doctor if I need to be concerned about my apical cyst issue, given that I currently have no discomfort.
Thank you.

Hello: Since you are already scheduled for dental cleanings every six months, if you are feeling no discomfort, it is advisable to relax.
During your next routine check-up, you can remind the dentist to take an X-ray for confirmation.
Thank you, Dr.

When it comes to understanding apical cysts, particularly in the context of your past dental history, it's important to approach the situation with a balanced perspective. Based on your description, you had a periapical cyst (also known as an apical cyst) diagnosed approximately five years ago, following a history of trauma to the tooth. You underwent root canal treatment, which is a common and effective method for addressing issues related to apical cysts. The fact that the cyst appeared to shrink over time during follow-up visits is a positive sign, indicating that the treatment was effective.

Apical cysts are typically associated with the roots of teeth and can develop as a result of infection or trauma. They are often asymptomatic, meaning they do not cause noticeable symptoms, which can lead to a false sense of security. However, the absence of symptoms does not necessarily mean that the cyst has resolved completely. In your case, since you have not experienced any discomfort or issues in the past four years, it is likely that the cyst has either healed or is stable.

Your concern about oral cancer, particularly in relation to your past dental issues, is understandable, especially given the wealth of information available online that can sometimes lead to increased anxiety. However, it is crucial to differentiate between the risks associated with apical cysts and those associated with oral cancer. While chronic irritation or inflammation in the oral cavity can sometimes lead to changes in tissue that may be concerning, the likelihood of an apical cyst progressing to cancer is extremely low.

In general, if you have not experienced any symptoms such as pain, swelling, or changes in the appearance of the gums or teeth in the area of the previous cyst, it is a good indication that there is no immediate cause for concern. However, it is also important to maintain regular dental check-ups, especially since you have a history of dental issues. Dentists can monitor any changes in your oral health and provide reassurance or intervention if necessary.

If you are feeling particularly anxious about your dental health or the possibility of oral cancer, it may be beneficial to schedule a dental appointment for a thorough examination. A dentist can take new X-rays to assess the current state of the tooth and surrounding bone, providing you with updated information and peace of mind.

In summary, while it is natural to feel concerned about past dental issues, the absence of symptoms over several years is a positive sign. Regular dental check-ups are essential for monitoring your oral health, and if you have specific concerns, discussing them with your dentist can help alleviate anxiety and ensure that any potential issues are addressed promptly. Remember, maintaining good oral hygiene and staying proactive about your dental health are key components in preventing future complications.

Dr. He Jianxian reply Ophthalmology
Floaters generally do not cause a sensation of eye swelling, and most ophthalmologists should be capable of performing an examination for floaters. If a dilated eye exam has been conducted and both the retina and optic nerve are normal, there is usually no need for concern.
