What to Expect After a Dental Filling

Getting a filling is an important part of protecting your teeth and preventing further decay. Once the decayed portion is removed and the tooth is restored, it should function normally again. But in the first few days after treatment, it’s common to notice some temporary changes in how your tooth feels. This guide will help you know what’s normal—and what’s not—so you feel confident during the healing process.

Temperature Sensitivity

It’s normal for a tooth to be temporarily sensitive to hot or cold after a filling, especially cold. This sensitivity typically begins to improve over a few days and may take up to a couple of weeks to fully settle.

If the sensitivity worsens over time, doesn’t begin to improve, or lasts longer than two weeks, that’s something we want to check. It could indicate an issue that needs further attention.

What the Filling Feels Like

Your tongue may notice the new filling before anything else. It might feel a little different in texture or shape compared to your natural tooth. That’s expected.

What’s not normal is any sharp edge or area that feels rough or irritating to your tongue or cheek. If it feels sharp in any way, or if you can’t stop noticing it, give us a call. A quick adjustment in the office can usually take care of it.

Soreness at the Injection Site

Some mild soreness or tenderness in the area where you received the anesthetic is also common. This may feel like a bruise and should improve within a few days. A warm compress or over-the-counter pain relievers can help if needed.

When to Contact the Office

Please let us know if you experience any of the following after your filling:

A bite that feels uneven or off in any way .
Plaque’s Perfect Hiding Spot: The slight ridge at the crown margin creates an ideal location for plaque to accumulate, often just below the gumline where it’s difficult to clean effectively.
Sharp pain or discomfort when biting
Cold sensitivity that doesn’t improve or worsens over time
A filling that feels sharp, rough, or irritating
Any concerns that don’t seem to be getting better after a few days

Early adjustments can prevent more complicated issues down the line. We always want you to feel comfortable and confident about your treatment.

Consider this simple math: replacing a crown typically costs around $1,000-1,500. A dental implant to replace a tooth that couldn’t be saved? That’s often $4,000-5,000.

Proactive replacement isn’t just healthier for your mouth – it’s significantly friendlier to your wallet.

Frequently Asked Questions

1. How long should I wait to eat after a filling?

Wait until the numbness wears off completely before eating. This helps prevent accidental biting of your cheek or tongue.

2. Can a filling fall out?

While it’s not common, a filling can loosen or fall out—especially if you chew something very hard or sticky too soon. If this happens, contact us right away.

3. Do I need to take special care of my tooth?

No special care is needed beyond your regular brushing, flossing, and checkups. That’s the best way to keep your restored tooth healthy.
