Toothache


I have a tooth on the lower left side that is broken in half but doesn't hurt.
However, in the past few days, I've suddenly experienced pain when biting down and even with light pressure, making it difficult to eat.
What could be the reason for this?

Hello, in cases of fractured teeth, the dental pulp usually undergoes necrosis.
The absence of pain is often due to chronic inflammation.
However, if the immune system is compromised or there is an oral infection, it can progress to acute periapical periodontitis, which will cause pain upon pressure.
There may also be discomfort at the root exit of the tooth in the oral cavity.
Root canal treatment should be performed.
Wishing you peace and health.
Sincerely, Dr.
Huang Chih-Cheng, Director of Dentistry, Taoyuan General Hospital, Ministry of Health and Welfare.

Tooth pain can arise from a variety of causes, and understanding these can help in finding appropriate solutions. In your case, you mentioned that you have a tooth on the lower left side that is broken but not painful, yet you are now experiencing pain when biting or applying light pressure. This situation can be concerning, and it’s important to consider several potential underlying issues.

1. Cracked Tooth Syndrome: Even if the tooth is broken, it may not always cause immediate pain. However, the fracture can lead to sensitivity or pain when biting down, especially if the crack extends into the tooth's nerve. This condition is known as cracked tooth syndrome, and it can cause intermittent pain that may worsen with pressure.

2. Pulpitis: The dental pulp, which contains nerves and blood vessels, can become inflamed due to trauma or decay. If the pulp is irritated, it can lead to a condition called pulpitis, which can cause significant pain when pressure is applied. This inflammation can occur even if the tooth does not appear to be decayed or infected externally.

3. Periodontal Issues: Sometimes, pain can be referred from the gums or surrounding tissues. If there is inflammation or infection in the gums (gingivitis or periodontitis), it can cause discomfort that feels like it’s coming from the tooth itself.
4. Occlusal Trauma: If your bite is misaligned, it can lead to excessive pressure on certain teeth, causing pain when biting down. This is known as occlusal trauma and can occur even if the tooth itself is not damaged.

5. Referred Pain: Pain can sometimes be referred from other areas, such as the jaw or even from sinus issues. The trigeminal nerve, which supplies sensation to the face and teeth, can sometimes cause pain to be felt in areas that are not directly affected.

Given these possibilities, it is crucial to seek a thorough examination from a dentist. They may perform X-rays to check for hidden fractures, assess the health of the pulp, and evaluate the surrounding gum tissue.

Solutions and Recommendations:
1. Immediate Care: Until you can see a dentist, avoid chewing on the affected side to prevent further irritation. Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage discomfort temporarily.

2. Dental Visit: Schedule an appointment with your dentist as soon as possible. They may recommend treatments such as:
- Root Canal Therapy: If the pulp is infected or inflamed, a root canal may be necessary to relieve pain and save the tooth.

- Crown Placement: If the tooth is structurally compromised, placing a crown can help protect it from further damage.

- Occlusal Adjustment: If misalignment is the issue, your dentist may adjust your bite to alleviate pressure on the affected tooth.

3. Follow-Up Care: After treatment, follow your dentist’s recommendations for care, including maintaining good oral hygiene and attending regular check-ups to monitor your dental health.

In summary, while the broken tooth may not have been painful initially, the recent onset of pain suggests an underlying issue that requires professional evaluation. Prompt attention to dental discomfort is essential to prevent further complications and ensure your oral health remains intact.
