Tooth Sensitivity: Causes and When to See a Dentist - Dentistry

More Info

---

Tooth sensitivity can be a perplexing issue, especially when it persists over an extended period, as in your case. Based on your description, it seems that the sensitivity began after you had a cavity filled in one of your upper front teeth. This could indeed be related to the dental work you had done, but let’s explore the potential causes and when it’s advisable to see a dentist.


Causes of Tooth Sensitivity
1. Dental Work: After a filling, it’s not uncommon for the tooth to be sensitive to temperature changes. This sensitivity can occur due to the material used in the filling, the depth of the cavity, or even the technique employed during the procedure. If the filling is too high, it can cause discomfort when biting down.

2. Gum Recession: If the gums recede, the tooth roots can become exposed, leading to sensitivity. This is often exacerbated by brushing too hard or periodontal disease.

3. Cracked Tooth: A crack in the tooth can lead to sensitivity, especially when pressure is applied or when consuming hot or cold substances. The crack may not always be visible, and it can lead to more serious issues if not addressed.

4. Pulpitis: Inflammation of the dental pulp (the innermost part of the tooth containing nerves and blood vessels) can cause significant sensitivity and pain. This condition may arise from untreated cavities or trauma to the tooth.

5. Sinus Issues: Given that you mentioned sensitivity when pressing near your nose, it’s worth noting that sinus infections can sometimes cause referred pain to the upper teeth, particularly the incisors and canines.


When to See a Dentist
Given that your sensitivity has persisted for over two years without significant improvement or worsening, it is advisable to consult a dentist. Here are some specific reasons to seek professional help:
- Persistent Symptoms: If the sensitivity has not improved over time, it may indicate an underlying issue that requires attention.
- Pain with Pressure: The acid-like sensation you feel when pressing on your gums or near your nose could suggest an issue with the tooth or surrounding structures that needs evaluation.

- Changes in Sensitivity: If you notice any changes in the nature or intensity of your sensitivity, such as increased pain or discomfort, this warrants a dental visit.

- Impact on Daily Life: If the sensitivity is affecting your ability to eat, drink, or maintain oral hygiene comfortably, it’s time to seek help.


What to Expect at the Dentist
During your visit, the dentist will likely perform a thorough examination, which may include:
- Clinical Examination: Checking for visible signs of decay, cracks, or gum disease.

- Percussion Testing: Tapping on the tooth to assess sensitivity and pain response.

- Thermal Testing: Applying hot or cold stimuli to determine the tooth's response.

- X-rays: To check for any underlying issues not visible during the clinical examination, such as infections or bone loss.


Conclusion
In summary, your tooth sensitivity could be related to the dental work you had done, but it may also involve other factors such as gum health, tooth integrity, or even sinus issues. Given the duration and nature of your symptoms, it is advisable to see a dentist for a comprehensive evaluation. Early intervention can help prevent more serious complications and improve your quality of life. Don’t hesitate to reach out to a dental professional to discuss your concerns and get the appropriate care.
