How Do I Know If My Dentist’s Diagnosis for Tooth Sensitivity Is Correct?

I have an upper left molar with a large filling sensitive to hair, heat, and cold. After an air sensitivity test, my dentist put a desensitizing get on the tooth. She said if the pain lingers, then removing the nerve would relieve the sensitivity. Is a quick air test enough to diagnose the problem? My dentist works and talks fast, so how do I know she didn’t skip a test or fail to give me details on what’s happening? What if the filling is thinning out or has a hole in it? – Thanks.

Taylor,

The cause of dental pain can sometimes be readily identified, while other times it requires further investigation.

When a tooth is sensitive to air, there may be exposed, sensitive areas on the tooth. A desensitizing bonding agent can often address this.

  • Brief discomfort that subsides quickly may suggest a reversible irritation of the tooth’s nerve.
  • Persistent pain following air exposure often signals irreversible nerve damage, necessitating root canal treatment.

Your dentist may also use cold, heat, or electrical stimulation to assess the tooth’s condition.

While it’s difficult to speculate without a thorough examination, a thinning filling is less likely to cause sensitivity. However, leakage around the filling or decay beneath it are potential culprits.

Open and honest communication with your dentist is essential. If your dentist doesn’t address your concerns, we recommend seeking a second opinion from another dental professional.
