Sudden Pain in Fixed Dentures: Causes and Treatment Options - Dentistry

After a period of having fixed dentures, there is a sudden onset of pain in the dentures?


Hello, doctor.
I have a fixed dental prosthesis on both the upper and lower right sides.
Initially, everything was functioning normally after the adjustment period, but recently I've been experiencing pain when biting with the upper right prosthesis, and there is also soreness when my teeth come together (it feels like the pain is coming from inside).
Could you please explain what might be causing this? Is there a risk that I may need to undergo root canal treatment again?

You, 20~29 year old female. Ask Date: 2020/06/28

Dear Ms.
You: Hello! It is still necessary to take an X-ray to determine the cause! Take care! Wishing you peace and smoothness in everything! Sincerely, Dr.
Huang Ting-Fang, Dentistry.

More Info


Sudden pain in fixed dentures can be a concerning issue, especially when it disrupts your daily activities and eating habits. There are several potential causes for the pain you are experiencing, and understanding these can help guide you toward appropriate treatment options.

1. Underlying Dental Issues: One of the most common reasons for pain associated with fixed dentures is an underlying dental issue with the natural teeth that support the denture. If there is decay, infection, or even a crack in the supporting teeth, it can lead to pain that feels like it is coming from the denture itself. Additionally, if there has been any trauma to the area, it could also cause discomfort.

2. Gum Health: The health of the gums surrounding the fixed denture is crucial. If there is gum disease or inflammation, it can lead to pain and discomfort. This is particularly relevant if you notice any swelling, redness, or bleeding in the gums.
3. Denture Fit and Alignment: Over time, the fit of a fixed denture can change due to bone resorption or changes in the alignment of your teeth. If the denture is not fitting properly, it can put undue pressure on the underlying structures, leading to pain. This misalignment can also affect how your bite comes together, causing discomfort when chewing.

4. Nerve Involvement: In some cases, pain can be referred from the nerves in the jaw or teeth. Conditions such as trigeminal neuralgia or other nerve-related issues can manifest as pain in the area of the denture, even if the denture itself is not the direct cause.

5. Root Canal Treatment: If the pain is severe and persistent, there is a possibility that a root canal treatment may be necessary for one of the supporting teeth. This is especially true if the pain is deep and feels like it is coming from inside the tooth. A dentist would typically conduct a thorough examination, possibly including X-rays, to determine if there is an infection or other issues that would necessitate root canal therapy.


Treatment Options
- Consultation with a Dentist: The first step in addressing your pain should be to consult with your dentist. They will perform a comprehensive examination, including checking the fit of the denture, assessing the health of the gums, and possibly taking X-rays to evaluate the condition of the supporting teeth.

- Pain Management: In the meantime, over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage discomfort. However, this should not be a long-term solution, and it is essential to address the underlying cause of the pain.

- Adjustment of Dentures: If the issue is related to the fit of the denture, your dentist may need to adjust or reline the denture to ensure it fits properly and does not cause undue pressure on the gums or teeth.

- Root Canal Treatment: If an infection or decay is found in one of the supporting teeth, root canal treatment may be necessary to alleviate pain and save the tooth.

- Follow-Up Care: After treatment, regular follow-ups are essential to monitor the situation and ensure that the pain does not return. Maintaining good oral hygiene and regular dental check-ups can help prevent future issues.

In conclusion, sudden pain in fixed dentures can arise from various causes, including underlying dental issues, gum health, fit and alignment of the denture, or nerve involvement. It is crucial to consult with a dentist to determine the exact cause and appropriate treatment options. Early intervention can prevent more severe complications and ensure that your dental health remains intact.
