"Can filling a tooth cause dental nerve pain?"

Tooth Filling May Cause Dental Nerve Pain

Tooth filling can potentially lead to dental nerve pain. This may arise from various causes such as irritation from filling materials, untreated pulpitis, or acute exacerbation of periapical periodontitis, necessitating prompt consultation with a specialist and corresponding treatment. Here are the possible reasons:

1. Irritation from Filling Materials: For teeth with a shallow degree of decay, the grinding process during filling and the filling material itself can stimulate the pulp. After filling, the pulp may be subjected to pressure, leading to irritative or compressive pain of the dental nerve, typically manifesting as soreness. This may gradually improve within 1-2 weeks.

2. Untreated Pulpitis: If the tooth decay is severe and accompanied by pulpitis, yet no treatment is administered to the pulp during filling and the cavity is filled directly with material, persistent dental nerve pain may occur after filling. It is recommended to remove the filling, perform pulp drainage to alleviate pain, extract the pulp, and conduct root canal therapy, followed by full crown restoration.

3. Acute Exacerbation of Periapical Periodontitis: Tooth filling can also trigger acute exacerbation of periapical periodontitis, characterized by continuous toothache resembling dental nerve pain. Opening the pulp chamber for drainage to relieve pain and conducting root canal therapy are advised. After the procedure, options like post-and-core restoration or full crown restoration can be considered.

Another possibility is that consuming excessively cold, hot, or acidic foods after filling may irritate the dental nerve, causing sensitivity and pain. If dental nerve pain persists after filling, it is crucial to seek medical attention promptly. Avoid self-medicating with painkillers and instead follow the dentist's recommendation for targeted treatment to prevent further complications or tooth loss.
