Lost Fillings

Lost Fillings

A lost filling can happen unexpectedly, leaving the affected tooth sensitive, painful, or at risk of further damage.

Fillings are designed to protect teeth that have been weakened by decay, but over time, they can become loose or fall out due to everyday wear, biting on hard foods, or changes in the tooth structure.

When a filling is lost, the exposed area of the tooth is no longer protected, which means bacteria can enter and cause further decay or even infection. That’s why it’s important to seek emergency dental care as soon as possible. At Kent Emergency Dentist, we offer same-day appointments across Maidstone, Canterbury, Ashford, Dartford, Tunbridge Wells, and other Kent towns, ensuring you can get relief and treatment without delay.

Why a lost filling needs immediate care
While losing a filling may not always cause severe pain straight away, it should not be ignored. The filling was placed to restore part of a damaged tooth, and without it, the tooth is left exposed and vulnerable. Seeking prompt care helps to:

Prevent further tooth decay in the exposed area.

Relieve discomfort and sensitivity.

Protect the inner layers of the tooth.

Reduce the risk of infection or more complex treatment later.

What to do if a filling falls out
If your filling comes loose or falls out, here are some useful steps you can take until you see an emergency dentist:

Keep the tooth clean – Rinse gently with warm water after eating.
Avoid chewing on that side – This prevents further damage to the exposed tooth.
Use dental wax or sugar-free gum – If the cavity feels sharp, covering it can help protect your tongue and cheek.
Save the filling if possible – Bring it to your appointment, as it may help your dentist assess the situation.

Common reasons fillings fall out
Fillings can last many years, but they are not permanent. Some of the most common reasons for a filling coming loose or falling out include:

Normal wear and tear over time.
Biting into very hard foods.
Pressure from teeth grinding or clenching.
Decay developing underneath or around the filling.
Trauma or injury to the mouth.

Whatever the cause, replacing the lost filling promptly is the best way to protect your oral health.

What to expect at your emergency appointment
When you visit Kent Emergency Dentist with a lost filling, the dentist will:

Examine the tooth to check for new decay or damage.
Take X-rays if necessary to assess the tooth structure and roots.
Clean the cavity area to remove any debris or bacteria.
Recommend the most suitable treatment, depending on the condition of the tooth.

Treatment options for lost fillings
The right treatment depends on the size of the cavity, the condition of the tooth, and whether there are signs of further decay. Options may include:

Replacement filling – A new filling, usually made from tooth-coloured composite material, is placed to restore the tooth.
Dental inlay or onlay – For larger cavities, an inlay or onlay may be recommended to provide extra strength.
Dental crown – If the tooth is significantly weakened, a crown may be placed to protect it and restore function.
Root canal treatment – If the tooth pulp is affected by decay or infection, root canal therapy may be required before restoring the tooth with a crown.

Aftercare and recovery
Once your filling has been replaced or restored, your dentist will give you advice on how to protect your tooth moving forward. This may include:

Avoiding hard or sticky foods for a short period.
Maintaining excellent oral hygiene to reduce the risk of further decay.
Attending regular check-ups to monitor existing fillings and restorations.
Considering a mouth-guard if teeth grinding is contributing to filling wear.
