When receiving a dental filling, your dentist is likely to explain that you should not expect it to stay in place forever. These restorations usually last only a decade before needing to be replaced. Unfortunately, situations can arise that cause fillings to fall out, and when they do, you may be inclined to panic. There are things you can do to minimize your risk, but it’s best to know what to do should you experience this type of scenario.

What Can Cause a Dental Filling to Fall Out?

There are several reasons why a dental filling might fall out, including:

  • Facial trauma that affects the tooth and/or root
  • Biting down on hard, crunchy, or chewy foods
  • Grinding or clenching your teeth (Bruxism)
  • Dental decay that forms around the tooth

How Should You Handle a Lost Dental Filling?

While a lost dental filling is considered an emergency, many dentists may not provide same-day treatment but instead encourage you to come in within 2 or 3 days of the incident. No matter what they recommend, you can expect to follow these steps should you have a filling fall out:

  1. Call your dental office and let them know what happened. This will let them know about your situation so they can find a time for you to come in for treatment. Also, your dental team can provide first-aid tips to help you manage any discomfort and prevent further issues while at home.
  2. If you find the filling, store it in a small container and bring it with you to your appointment. Your dentist may be able to reattach it.
  3. Gargle with warm salt water to clean your mouth and remove any debris that might still exist. This will minimize harmful bacteria that may try to reinfect your tooth.
  4. Continue to practice good oral hygiene, but be mindful about brushing gently near the tooth with the missing filling.
  5. Do not chew or eat on the side of your mouth with the lost filling.
  6. Apply orthodontic wax to protect the tooth while waiting for your dental appointment.

Once you are at the dentist’s office, you can expect them to evaluate the tooth and your filling. If it is still intact and in good shape, they may be able to re-bond it. Otherwise, a new filling will be required.

Do not begin to panic if you lose your dental filling. Instead, follow the steps provided to safeguard your smile while you wait for your dentist to restore your tooth, ensuring optimal protection.
