Sensitivity after Dental Fillings

It's possible that the cavity was deeper than initially thought. When a filling is placed, it can sometimes irritate the nerve inside the tooth. This can cause sensitivity or pain. If the irritation is severe or persistent, it can lead to nerve damage.

A root canal is a procedure that removes the damaged nerve and pulp tissue from the inside of the tooth. This is often necessary to prevent further infection and save the tooth.

Here are some common reasons why a root canal might be needed after a filling:

• Deep cavity: If the cavity was very deep, it may have reached the nerve.

• Infection: Bacteria can sometimes enter the tooth through a cavity and infect the nerve.

• Trauma: A tooth injury can also damage the nerve.

If your dentist has recommended a root canal, it's important to follow their advice. A root canal can be a successful procedure, and it can help you keep your natural tooth.

Do note that if it hurts to chew AND you have hot/cold sensitivity with a newly placed filling, the most common reason is the filling was placed too high and a simple adjustment will fix that problem without a root canal being needed!
