Jaw Pain After Dental Fillings: Causes and Solutions - Dentistry

Share to:

Dental filling; pain in front of the ear when opening the mouth; temporomandibular joint pain; occlusal issues?


Hello! Two weeks ago, I visited the dentist for a routine check-up.
In addition to a teeth cleaning, the dentist filled a cavity on my upper right tooth where the previous white filling had fallen out, replacing it with silver amalgam.
A total of three fillings were done (two between teeth, leaving some space).
The filling procedure was very quick, but I felt significant pressure during the process.
Unlike previous visits, the dentist did not use bite paper to check the occlusion at the end of the procedure.
However, the dentist verbally asked if I felt any discomfort with my bite, and I did not experience any at that time.
I had previously had silver amalgam fillings on different teeth, so we concluded the treatment.
Unexpectedly, about a week later, which was four days ago, I began to feel pain in front of my right ear, and the pain has intensified today.
Although I do not hear any clicking sounds when opening my mouth, I do feel soreness and discomfort when opening my mouth about 2-3 fingers wide, but it is still bearable.
Could this phenomenon be due to the fillings being too thick, causing an improper bite? (I found that the painful area is at the temporomandibular joint (TMJ).
I have never experienced TMJ pain before, nor do I have a habit of grinding my teeth at night.
My family suggests that it could be due to poor sleep quality and lack of sleep, but even after four days of sleeping more than eight hours each night, there has been no improvement.
Online resources indicate that there are many potential causes for TMJ pain, so I am uncertain if it is related to the dental work, and I don’t know how to proceed.
I feel very troubled.)

Hello: First, let's clarify your concerns.
1.
You are experiencing discomfort in your temporomandibular joint (TMJ).
2.
You had a dental filling two weeks ago, but you do not feel any issues with your bite.
If the above is correct, we should first address the symptoms of your TMJ discomfort, which may include applying hot and cold compresses along with muscle relaxants, among other treatments.
It is indeed possible that the dental filling could have caused bite discomfort, leading to TMJ pain; however, since you do not currently have any bite issues, we will rule out the filling as a problem for now.
If your condition does not improve after a few weeks of treatment, I would then recommend considering the removal of the amalgam filling.
Wishing you peace and good health.

More Info


Jaw pain after dental fillings can be a frustrating and uncomfortable experience, particularly when it arises unexpectedly after a dental procedure. In your case, it seems that the pain began about a week after you had fillings done on your upper right teeth, and it has progressively worsened to the point where you are experiencing discomfort in the area near your ear and some pain when opening your mouth.
There are several potential causes for your symptoms, and understanding them can help you find the right solution.

1. Occlusal Issues: One of the most common reasons for jaw pain after dental fillings is an improper bite or occlusion. If the filling is too high or thick, it can interfere with the way your teeth come together when you bite or chew. This misalignment can lead to discomfort in the jaw muscles and the temporomandibular joint (TMJ), which connects your jawbone to your skull. Since you mentioned that the dentist did not perform a bite test with articulating paper, it is possible that the filling may be affecting your bite.
2. TMJ Disorders: The pain you are experiencing could also be related to TMJ disorders, which can manifest as pain in the jaw joint, difficulty in jaw movement, and discomfort around the ear. Stress, teeth grinding, or clenching can exacerbate these symptoms, even if you do not have a history of bruxism (teeth grinding).
3. Inflammation or Infection: Although less common, inflammation or infection in the area of the filling can also cause pain. If the filling was placed near the pulp of the tooth, it could lead to pulpitis, which is inflammation of the tooth's nerve.
4. Muscle Strain: The process of having dental work done can sometimes lead to muscle strain in the jaw, especially if you had to hold your mouth open for an extended period. This strain can result in soreness and discomfort.


Solutions and Recommendations:
1. Return to Your Dentist: The first step you should take is to return to your dentist for a follow-up appointment. They can assess the fillings and check your bite. If the filling is too high, they can adjust it to ensure that your bite is correct, which may alleviate the pain.

2. Pain Management: In the meantime, over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage your discomfort. Applying a warm compress to the jaw area may also provide relief.

3. Jaw Exercises: Gentle stretching and relaxation exercises for the jaw can help reduce tension in the muscles. Open and close your mouth slowly, and try to move your jaw side to side gently.

4. Stress Management: If you suspect that stress may be contributing to your symptoms, consider incorporating relaxation techniques such as deep breathing, meditation, or yoga into your routine.

5. Sleep Hygiene: Ensure that you are practicing good sleep hygiene. Although you mentioned that you are getting sufficient sleep, the quality of sleep is also important. Avoid screens before bed, create a comfortable sleep environment, and establish a calming bedtime routine.

6. Consult a Specialist: If your symptoms persist despite these measures, consider consulting a specialist, such as an oral surgeon or a dentist who specializes in TMJ disorders. They can provide a more comprehensive evaluation and recommend treatments such as physical therapy or a custom night guard if bruxism is suspected.

In summary, while it is possible that your jaw pain is related to the recent dental fillings, it is essential to have a thorough evaluation by your dentist to determine the exact cause and appropriate treatment. Addressing any occlusal issues promptly can help prevent further discomfort and ensure that your dental work is functioning as intended.
