It’s not uncommon to wonder why is my tooth still sensitive after a filling, especially if the discomfort lingers longer than expected. While some sensitivity is normal in the days following a Nerve Filling with Inflammation Treatment, persistent or sharp discomfort can raise concern. Understanding the reasons behind this sensitivity can help you determine if it’s a normal part of healing or a sign to return to the dentist.

What Causes Tooth Sensitivity After a Filling?

Tooth sensitivity after a filling is generally caused by irritation to the tooth's inner layers during the procedure. Several factors may contribute to this uncomfortable sensation:

• Depth of the cavity — If decay reached near the pulp or nerve, sensitivity is more likely
• Material of the filling — Some materials, like silver amalgam, conduct temperature more than others
• Bite misalignment — A high filling can create pressure that triggers pain or sensitivity
• Trauma from drilling — The dental process itself can inflame the nerves
• Exposed dentin — If the enamel was thin or worn, the sensitive inner tooth may remain exposed

Most sensitivity is temporary, but if it persists, it could indicate a deeper issue.

Types of Sensitivity You Might Experience:

Sensitivity after a filling can vary in severity, duration, and triggers. Paying attention to what causes your discomfort can help in identifying the underlying reason:

• Cold sensitivity when eating ice cream or drinking water
• Heat sensitivity when consuming hot beverages or soups
• Pressure sensitivity when biting or chewing
• Spontaneous pain that comes and goes without provocation
• Lingering sensitivity that lasts more than 30 seconds after exposure

These clues can help your dentist determine whether the filling is settling in or if further treatment is needed.

How Long Should Sensitivity Last?

If you're asking yourself, why is my tooth still sensitive after a filling, it's important to know what’s considered normal. Some post-procedure sensitivity is expected, especially in the first week. Here’s a general guideline for what to expect:

• Mild sensitivity should improve within a few days to two weeks
