Lost a filling? What to do and when it becomes urgent

A lost filling is one of the most common dental situations people encounter, and reactions to it range from immediate panic to complete indifference. The reality sits somewhere in between. A lost filling does not automatically constitute an emergency, but it does require attention, and how quickly depends on what you are experiencing.

Why fillings fall out

Fillings can come out for several reasons. The most common is recurrent decay beneath or around the filling, which weakens the bond between the restoration and the tooth. Fillings can also fail because of age, biting forces, or a chip in the tooth structure that takes part of the filling with it.

A filling falling out is not a neutral event. It means the tooth structure beneath it is now exposed and unprotected.

What to do immediately

Retrieve the filling if you can and bring it to your appointment. Occasionally, it can be rebonded.

Keep the area clean. Rinse with warm water after eating and brush the area gently. Food packing into an open cavity causes rapid decay and can be painful.

Use temporary filling material from a pharmacy if the tooth is painful or you cannot get a dental appointment quickly. These products are designed for short-term use only and are not a substitute for proper treatment.

Avoid chewing on that side of the mouth until the tooth has been restored.

When it is urgent

A lost filling becomes urgent when any of the following apply:

The tooth is causing significant pain, which suggests the nerve is exposed or decay has reached the pulp. There is visible decay in the cavity, or the tooth looks dark or soft. Part of the tooth has broken away along with the filling, leaving sharp edges. You notice swelling in the gum near the tooth, which may indicate an abscess developing.

If any of these apply, contact Berkhamsted Dental on 01442 865 646 promptly. We treat dental emergencies and will advise on the urgency of your situation.

Treatment for a lost filling

Depending on how much tooth structure remains and the extent of decay, treatment may involve a new composite filling, a larger composite build-up, or a crown if the tooth is significantly weakened. In cases where decay has reached the pulp, root canal treatment will be required first.

The longer a lost filling is left untreated, the more likely it is that a simple replacement filling becomes a more complex, more expensive procedure. Book a check-up at Berkhamsted Dental today.

  • Great service and lovely staff! Emily on reception was fantastic :)

  • Greeted warmly by everyone. Treated respectfully by my dentist with step by step explanations regarding my treatment. Consequently, I was able to feel more relaxed having been reassured that all was going well. Thank you for an excellent outcome.

    Very happy with my Invisalign process with Kish. He kept me well informed throughout and always took time to answer all my many queries. The price was reasonable compared to others in the area and it has all been completed within the original time advised. I'm yet to have my composite bonding done but hope to have a transformed smile in the end. Would thoroughly recommend BDP if you're considering Invisalign.

    I have just completed the main part of my Invisalign journey followed by composite bonding and could not be happier. Having been told by my previous dentist that it wasn’t worth doing ( due to my age and small change I would achieve) I had a consultation with Dr Kish to start a programme of Invisalign to straighten out my front teeth which had moved over time and now had a very slight overlap. Once complete, I saw Dr Ventsi for bonding to the edges of 6 teeth, which, as a heavy tooth grinder, were chipped and uneven. Both Drs were knowledgeable and lovely to deal with. I could not be happier with the result! A little change has made a huge difference !
