How long does numbness last after a dental filling?

Dental numbing blocks nerve signals that carry pain signals to your brain. That’s what keeps you comfortable during a dental procedure.

When Dr. Navid JavadiThis link leads to Doctor’s page performs a dental fillingThis link leads to Family Dentistry page, the local anesthetic temporarily slows communication between major nerves and the brain. It also affects nearby blood vessels, which helps control blood flow during treatment.

Dental numbness is not a complication. It’s a sign that your dentist prioritized comfort and safety.

What affects how long numbness lasts?

You might notice that numbness lasts longer for you than for someone else. That’s normal.

Several factors influence numbness duration:

• Blood flow and blood circulation
