Caring for Renton patients at our Port Dover office
See every dental service for RentonWhen dental work comes loose
A lost filling or crown is usually fixable, but the exposed tooth needs protecting.
Fillings and crowns can loosen or fall out because of new decay underneath, wear of the cement, a hard or sticky bite or a crack in the tooth. Sometimes there is no pain at all; other times the exposed tooth becomes sensitive to air, temperature or sweets. Either way, the tooth is more vulnerable to breaking or decaying further until it is repaired.
If a Renton patient loses a filling or crown, calling our Port Dover office soon is the best next step. Describe what came out, whether the tooth hurts and whether you still have the crown. The team will advise on protecting the tooth in the meantime and discuss how soon an appointment should be arranged.
Right away
A few simple steps help until you can be seen.
Save what came out
If a crown has come off, keep it in a clean, sealed container and bring it with you. Do not throw it away even if it looks damaged, as it can sometimes be recemented. For a lost filling, there is usually nothing to save, but note whether you swallowed a piece or found it, and check the tooth for sharp edges or visible dark areas.
Protect the tooth
Rinse gently with warm water and keep the area clean. Avoid chewing on that side, and steer clear of very hot, cold, sweet or sticky foods. Over-the-counter temporary filling material from a pharmacy can cover a hole or help hold a crown temporarily. Follow package instructions carefully and never use household glues of any kind to reattach a crown.
How urgent is it?
Symptoms help determine how quickly you should be seen.
Signs to mention promptly
Severe pain, swelling, a broken tooth underneath, sharp edges cutting your cheek or tongue or a front crown that affects your appearance at work are reasons to call promptly. Pain that keeps you awake or throbs may indicate the nerve is involved. Mention these details so the team can give appropriate advice and prioritize the appointment accordingly.
When a short wait may be reasonable
If the tooth is comfortable and there is no visible damage beyond the lost filling or crown, a short wait may be reasonable, though the tooth should still be repaired soon. Exposed tooth structure can decay or break more easily. Call the office to explain your situation so the team can recommend a suitable appointment time.
The repair visit
The dentist checks why the restoration failed.
Recementing or replacing
The dentist examines the tooth and the lost restoration. If a crown is intact and the tooth underneath is healthy, it may be cleaned and recemented. If the crown is damaged, a new one may be needed, with a temporary in the meantime. A lost filling is generally replaced with a new restoration after any decay has been removed.
Treating what lies underneath
Decay under the old restoration, a fractured tooth or nerve problems may need additional treatment before a new filling or crown can be placed. X-rays help assess this. The dentist will explain what was found and outline the options, which might include a larger restoration, an onlay, a new crown or root canal treatment if needed.
Preventing a repeat
Protect the repair with good habits and checkups.
Caring for the repaired tooth
Follow instructions about eating after the repair, especially if cement needs time to set or numbing was used. Avoid very sticky foods such as toffee or caramel on that tooth. Brush gently and clean between teeth to remove plaque from the edges of the restoration. Contact the office if the bite feels high or sensitivity persists.
Reducing future risk
Regular checkups let the dentist spot worn or leaking restorations before they fail. If you grind your teeth, ask about a night guard. Avoid chewing ice and hard objects. Renton patients who know a filling is old or showing wear can ask about planned replacement before it causes an unexpected trip to the office later.

Lost filling and crown questions
Have a question about your situation? Our team can help you plan a visit.
Can I glue my crown back on myself?
Do not use household glue, which can damage the crown and tooth and make proper repair harder. Pharmacy temporary cement may hold it briefly, but call the office for guidance first. A dentist should check and recement the crown properly.
Is a lost filling an emergency?
It depends on symptoms. Pain, swelling or a broken tooth make it more urgent. Even without pain, the tooth should be repaired soon to prevent further damage. Call the office and describe your situation so the team can advise.
Why did my crown fall off?
Common reasons include decay under the crown, cement wearing away, a crack in the tooth or a hard or sticky bite. The dentist will examine the tooth to find the cause before deciding how to repair it.
Can the same crown be put back on?
Often, if the crown is intact and the tooth beneath is healthy. If there is decay, a fracture or the crown is damaged, a new one may be needed. Keep the crown safe and bring it to your appointment so it can be assessed.
What if I swallowed my filling or crown?
Small fillings usually pass without harm. If you swallowed a crown and feel fine, it often passes as well, but mention it to the dental team. Seek medical help if you have chest pain, coughing or trouble breathing, which could suggest it was inhaled.
