If your filling falls out, keep the area clean, avoid chewing on that side and bring the lost piece to your appointment if possible. A missing filling isn’t always an emergency, but it needs prompt attention to prevent decay or sensitivity. Radiant Smiles Dental Bundoora can replace the filling safely and check for underlying causes.
It can be worrying to feel a filling come loose or fall out, especially if you suddenly notice sensitivity or a sharp edge on your tooth. The good news is that a lost filling isn’t usually an emergency, but it does need prompt attention from your dentist to prevent further damage.
At Radiant Smiles Dental Bundoora, we often see patients who lose a filling while eating or brushing. Knowing what to do in those first few hours can make a big difference to your comfort and oral health.
Why Fillings Fall Out
Dental fillings can come loose for several reasons.
- Wear and tear over time: Everyday chewing pressure can gradually weaken the bond.
- Tooth decay around the filling: New decay underneath or beside the old filling can cause it to separate.
- Biting hard foods: Crunchy foods such as nuts, lollies or ice can cause stress fractures.
- Teeth grinding (bruxism): Constant clenching or grinding can wear down fillings faster.
- Accidental trauma: A fall, knock or biting something unexpectedly hard can dislodge a restoration.

What to Do When a Filling Falls Out
Here are safe, practical steps you can take before you see your dentist.
1. Stay calm and keep the area clean
Rinse gently with warm water to remove any food debris. Avoid using mouthwash that contains alcohol, as it can irritate exposed tissue.
2. Keep the lost filling if possible
If you can find the piece, place it in a clean container and bring it to your appointment. It may help your dentist assess why it came loose.
3. Avoid chewing on that side
Chewing on the affected tooth can cause more damage or discomfort. Stick to soft foods and avoid very hot, cold or sticky foods until it’s repaired.
4. Use temporary dental material if needed
If you have a temporary repair kit from the chemist, you can use it to protect the exposed area for a short time. These are suitable for temporary relief only and should never replace professional care.
5. Book an appointment as soon as possible
Even if you’re not in pain, it’s best to arrange a dental visit promptly. The exposed part of your tooth can be sensitive and more prone to decay.

What Not to Do
Avoid these common mistakes after a filling falls out.
- Do not ignore it. The longer you wait, the greater the chance of infection or more serious decay.
- Do not use glue or household materials. These can irritate your gums or damage the tooth.
- Do not eat on that side. Chewing puts pressure on the exposed area and can make the situation worse.
When to Seek Urgent Care
A lost filling doesn’t always require emergency treatment, but you should contact your dentist right away if you experience:
- Severe or increasing pain
- Swelling around the tooth or jaw
- Signs of infection such as throbbing or fever
- A filling that fell out following trauma or a crack in the tooth

How Your Dentist Repairs a Lost Filling
At your appointment, your dentist will:
- Examine the tooth to determine why the filling came out
- Remove any debris or decay
- Replace the filling using a durable composite resin that matches your natural tooth colour
If the tooth structure is severely damaged, a dental crown may be recommended. You can read more about that treatment in our article on dental crowns vs fillings.
Preventing Future Filling Problems
A few simple habits can help your new fillings last longer:
- Brush twice daily with fluoride toothpaste
- Floss between teeth to remove plaque buildup
- Wear a mouthguard if you grind your teeth
- Visit your dentist for regular check-ups and cleans
Keeping up with routine care helps detect early signs of wear before a filling becomes loose or damaged. You can book your next check-up directly through our homepage.
