Persistent toothache?


Hello Dr.
Tseng, my first molar has been uncomfortable for the past month and a half.
I feel like I might have accidentally bitten down hard while sleeping.
Last month, I had an X-ray taken, but it didn't show any issues.
The symptoms have progressed from a dull ache to sharp pain when lying down, a sensation of bleeding inside the tooth, discomfort while biting, and swelling after eating.
Recently, when I touch the occlusal surface with my tongue at certain angles, I can hear what sounds like fragments of the tooth inside.
Is it possible that it has fractured internally?

Dr. Zeng Guanghui reply Dentistry


It is possible for teeth to develop cracks due to excessive occlusal forces, leading to inflammation of the dental pulp.
It is recommended to return for a follow-up appointment for a detailed examination by a dentist.

More Info


Persistent tooth pain, especially in the molars, can be a complex issue with various underlying causes. Given your symptoms, it is essential to consider several possibilities that might explain the discomfort you are experiencing.


Possible Causes of Tooth Pain
1. Dental Caries (Cavities): Even if X-rays did not show any issues, there could still be decay that is not easily visible. Cavities can cause pain, especially when they reach the inner layers of the tooth, affecting the nerves.

2. Cracked Tooth Syndrome: The sensation of hearing "fragments" when you touch the tooth with your tongue could indicate a crack in the tooth. This condition often leads to pain when chewing or biting, and the discomfort can vary depending on the position of the tooth and the force applied.

3. Pulpitis: Inflammation of the dental pulp (the innermost part of the tooth containing nerves and blood vessels) can cause significant pain. This condition can arise from untreated cavities, trauma, or cracks. Symptoms may include throbbing pain, sensitivity to temperature changes, and swelling.

4. Periodontal Issues: Gum disease can also lead to tooth pain. If the gums are inflamed or infected, they can cause discomfort around the affected tooth. Symptoms may include swelling, bleeding, and pain when chewing.

5. Sinus Infection: Sometimes, pain in the upper molars can be referred pain from sinus issues. If you have sinus congestion or infection, it can lead to pressure and discomfort in the upper teeth.

6. Temporomandibular Joint (TMJ) Disorders: If you have been grinding your teeth or clenching your jaw (possibly during sleep), this can lead to pain in the molars and surrounding areas. TMJ disorders can cause discomfort in the jaw, ears, and teeth.


Recommended Solutions
1. Dental Evaluation: Since you have already seen a dentist, it may be beneficial to seek a second opinion, especially if your symptoms persist. A thorough examination, including a possible 3D cone beam CT scan, can help identify cracks or other issues that standard X-rays might miss.

2. Root Canal Treatment: If pulpitis is diagnosed, a root canal may be necessary to remove the inflamed or infected pulp and alleviate pain.

3. Dental Crown: If a crack is confirmed, placing a crown over the tooth can help protect it from further damage and relieve pain.

4. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage discomfort in the short term. However, these should not replace professional dental care.

5. Avoiding Hard Foods: Until you can see a dentist, try to avoid hard or chewy foods that may exacerbate the pain.

6. Oral Hygiene: Maintain good oral hygiene by brushing gently and flossing regularly to prevent further complications.

7. Stress Management: If you suspect that teeth grinding or jaw clenching is contributing to your pain, consider stress management techniques or a mouthguard to protect your teeth during sleep.


Conclusion
Persistent tooth pain, especially in the molars, should not be ignored. While there are several potential causes, a thorough evaluation by a dental professional is crucial for accurate diagnosis and treatment. Given the complexity of dental issues, it is always advisable to seek timely intervention to prevent further complications. If your symptoms worsen or new symptoms arise, do not hesitate to contact your dentist sooner than your scheduled appointment. Your oral health is paramount, and addressing these issues promptly can lead to better outcomes.
