What to do if you lose a filling or crown and when to see a dentist
Lost a filling or crown? Learn immediate steps to protect your tooth and prevent infection before your visit.

If you notice a sudden gap in your tooth or new sensitivity to hot or cold, you may have lost a filling or dental crown. This can leave the inner part of your tooth exposed and more sensitive to temperature, pressure and food.
It’s important to have the area evaluated as soon as possible. Aspen Dental offers same-day and walk-in appointments when available, so you can be seen and understand your next steps.
Is a lost filling or crown a dental emergency?
When a filling or crown is lost, the underlying tooth is no longer protected. You may notice sensitivity when breathing in, eating or drinking.
Even if there is no discomfort right away, the exposed area can weaken over time. It’s recommended to see a dentist within a day or two so the tooth can be evaluated and restored.
Your Aspen Dental care team will assess the area and determine whether the tooth can be restored with a new filling or crown.
Immediate steps to take if you lose a filling or crown
Find and save the restoration if possible
If your crown or filling has come out, try to locate it. In some cases, a crown may be able to be cleaned and reattached.
Place it in a small container and bring it with you to your appointment. If the piece cannot be found, your care team can create a replacement.
Keep the area clean
Rinse your mouth gently with warm salt water to help remove food particles from the exposed area.
Avoid brushing the area too aggressively, as it may be sensitive.
Protect the tooth temporarily
Over-the-counter dental cement or denture adhesive may help cover the exposed area for a short time.
If you have the crown, you may be able to place it back over the tooth temporarily. This is only a short-term step until you can see your Aspen Dental provider.
How lost fillings and crowns are treated at Aspen Dental
Your Aspen Dental office can evaluate the tooth and recommend the right treatment based on its condition.
Replacing a lost filling
If a filling has come out, your provider will clean the area and place a new filling. This helps seal the tooth and protect it from further damage.
Replacing or reattaching a crown
If your crown is intact and the tooth underneath is healthy, it may be cleaned and reattached.
If a new crown is needed, your care team will prepare the tooth and discuss next steps. In some cases, same-day crown options may be available depending on the office.

What should I do if my filling falls out?
Rinse your mouth gently and keep the area clean. You may use temporary dental cement for short-term protection. Schedule a visit as soon as possible so the tooth can be evaluated.
Does a lost filling require an emergency visit?
It’s best to be seen within a day or two. Even without discomfort, the exposed tooth can weaken or develop further issues if left untreated.

Not always. If treated early, the filling can often be replaced. If the inner part of the tooth becomes affected, additional treatment may be recommended.

It’s best to avoid chewing on that side of your mouth. Stick to softer foods and avoid very hot, cold or sweet items that may cause sensitivity.
