Why This Happens
It's common for a tooth to feel sensitive to hot, cold, or pressure for a few days to a couple of weeks after a filling. The tooth's nerve can be temporarily irritated by the preparation process itself, and it needs a little time to settle down — similar to how a bruise takes time to heal. This is especially common with larger or deeper fillings, since they sit closer to the nerve.
What's Normal vs. What's Not
Mild, brief sensitivity that fades within a couple of weeks is typical and usually nothing to worry about. What's worth a call is pain that's severe, that lingers long after the trigger is gone, that's worsening rather than improving, or that keeps you up at night. Pain when biting down specifically can sometimes mean your bite needs a small adjustment, which is a quick fix.
What to Do
Give it a little time, and avoid chewing directly on that tooth if it's tender. Over-the-counter pain relievers can help in the meantime. If sensitivity hasn't improved after two to three weeks, or if it's getting worse rather than better, call the office — a quick bite adjustment or a closer look often resolves it.
