What to Do If a Filling Falls Out: Steps to Protect Your Tooth

Dental fillings are one of the most common treatments for repairing cavities. While they are designed to be durable, fillings don’t last forever. Over time, chewing, grinding, and natural wear can weaken a filling and cause it to come loose. If this happens, you may be left wondering: what to do if a filling falls out?

Here’s what you need to know about handling this dental emergency, protecting your tooth, and getting it treated quickly.

Why Do Fillings Fall Out?

A dental filling may fall out for several reasons, including:

• New decay around the filling that weakens the tooth structure.

• Chewing hard foods like nuts, ice, or hard candy.

• Teeth grinding (bruxism) that puts extra pressure on the filling.

• Wear and tear over time, as most fillings last 5–25 years depending on the material.

Even with great oral care, a filling may eventually loosen or fall out. The important thing is to act quickly to protect your tooth.

What to Do If Your Filling Falls Out

1. Call Your Dentist Immediately

A missing filling leaves your tooth exposed and vulnerable to bacteria. Contact your dentist right away for an appointment. If you’re experiencing pain or swelling, you may need emergency dental care.

2. Save the Filling (If Possible)

If you can find the filling, keep it and bring it with you. Your dentist will determine if it can be reused or if you’ll need a replacement.

3. Rinse with Warm Salt Water

Rinsing your mouth with warm salt water helps clean the area and reduce bacteria until you can see your dentist.

4. Protect the Tooth Temporarily

If you can’t see a dentist immediately, cover the exposed tooth with dental wax or temporary filling material (available at most pharmacies). This will protect the area but should not replace professional care.

5. Avoid Chewing on That Side

Stick to soft foods and avoid chewing on the side of the missing filling to prevent further damage.

What Not to Do If a Filling Falls Out

• Don’t ignore it—delaying treatment can lead to infection or the need for more advanced care such as a root canal or dental crown.

• Don’t try to glue the filling back in place yourself. Household adhesives are unsafe and toxic.

• Don’t continue eating hard or sticky foods that can worsen the damage.

How to Prevent Fillings from Falling Out

While fillings may not last forever, you can extend their lifespan with proper care:

• Brush twice daily with a soft-bristled toothbrush and non-abrasive toothpaste.

• Floss daily to keep the edges of fillings free of plaque.

• Avoid chewing hard objects (ice, pens, hard candy).

• Treat teeth grinding with a custom nightguard.

• Visit your dentist every six months for regular cleanings and exams.

Treatment Options After a Filling Falls Out

Depending on the condition of your tooth, your dentist may recommend:

• A new filling to restore the cavity.

• A dental crown if the tooth is severely weakened.

• Root canal therapy if decay or infection has reached the nerve.
