Toothache due to cavities?


Hello, doctor.
I had a tooth that was deeply decayed, and after seeing a dentist, it was filled.
However, I still feel a slight pain and my bite feels off; sometimes it feels like it's catching.
I'm very worried and hesitant to see a doctor again.

QQ, 10~19 year old female. Ask Date: 2020/10/13

Dear Miss QQ: Hello! (Your teeth have significant decay.) It is recommended to visit a major hospital for a thorough examination! If you experience pain when biting, you may need root canal treatment.
Take care! Wishing you peace and smooth recovery! Sincerely, Dr.
Huang Ting-Fang, Dentistry.

More Info


Tooth pain after a cavity filling can be a common concern for many patients. It's understandable to feel anxious about lingering discomfort, especially after undergoing a dental procedure. Here’s what you need to know about the potential causes of tooth pain following a filling and how to address it.


Understanding the Pain
1. Post-Operative Sensitivity: After a filling, it’s not unusual to experience some sensitivity in the treated tooth. This can occur due to the dental materials used, the procedure itself, or the tooth's response to the filling. Sensitivity to hot, cold, or pressure can last for a few days to a few weeks. If the pain is mild and gradually decreases, it may simply be a normal part of the healing process.

2. High Filling: If the filling is too high, it can cause discomfort when biting down. This is because the tooth may not be properly aligned with the opposing teeth, leading to undue pressure on the filled tooth. If you feel that your bite feels "off" or "catchy," it’s essential to return to your dentist for an adjustment.

3. Pulpitis: In some cases, the nerve inside the tooth (the pulp) can become inflamed after a filling, especially if the cavity was deep. This condition, known as pulpitis, can cause pain and discomfort. If the inflammation is severe, it may require further treatment, such as root canal therapy.

4. Cracked Tooth: Sometimes, a tooth may have a crack that was not visible before the filling. This can lead to pain when biting or when the tooth is exposed to temperature changes. If you suspect a crack, it’s crucial to have it evaluated by your dentist.

5. Infection: If bacteria have entered the tooth during the filling process or if the cavity was very deep, there’s a risk of infection. This can lead to more severe pain and may require additional treatment, such as antibiotics or a root canal.


What to Do Next
1. Monitor the Pain: Keep track of the pain level and any other symptoms you may experience. If the pain worsens or persists beyond a few weeks, it’s essential to seek dental care.

2. Return to Your Dentist: If you’re feeling uncomfortable or if the pain is affecting your daily life, don’t hesitate to return to your dentist. They can assess the filling, check your bite, and determine if any further treatment is necessary.

3. Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage discomfort. However, if the pain is severe or unmanageable, consult your dentist for stronger pain relief options.

4. Avoid Certain Foods: Until you can see your dentist, try to avoid very hot, cold, or hard foods that may exacerbate the pain.

5. Consider a Second Opinion: If you feel uncertain about your current dentist’s assessment or treatment plan, seeking a second opinion can provide peace of mind and alternative options.


Conclusion
Tooth pain after a filling can stem from various causes, ranging from normal post-operative sensitivity to more serious issues like pulpitis or infection. It’s crucial to listen to your body and seek professional advice if the discomfort persists. Remember, dental health is vital, and addressing issues early can prevent more significant problems down the line. Don’t let fear hold you back from seeking the care you need; your comfort and health are worth it.
