A lost filling is never a pleasant experience, but there’s no need to panic! This article will explain what to do if your filling falls out, how to quickly restore your tooth and prevent complications, and what steps to take if it happens unexpectedly at home.
Why Did the Filling Fall Out? Causes of Filling Loss

If your filling falls out, there are several possible reasons. Let’s examine why this can happen and what to do about it.
Incorrect Filling Placement
Poor-quality placement or inadequate preparation of the tooth before filling can result in the filling not staying in place. A dentist must properly clean the tooth of decay and other damage before placing a filling. If this step is skipped, the filling may fall out.
Low-Quality Materials
If a dentist uses subpar or expired materials, the filling may deteriorate and fall out sooner than expected. Using high-quality materials from trusted manufacturers ensures the filling's durability.
Mechanical Damage
Chewing hard foods (such as bones, nuts, or ice) or using teeth inappropriately (e.g., opening bottles) can cause the filling to fall out.
Filling Wear and Tear
Even well-placed fillings wear down over time due to chewing forces, leading to their eventual failure.
Poor Oral Hygiene
Failing to clean your teeth properly or using ineffective toothpaste can lead to cavity formation, which may weaken and dislodge the filling.
Temperature Changes
Frequent exposure to extreme temperatures (hot beverages followed by cold foods) can weaken the filling, causing it to fall out.
Individual Tooth Characteristics
Some people naturally have weaker teeth, making them more susceptible to losing fillings.
What to Do If a Filling Falls Out? – Important Steps
What should you do if your filling falls out and your tooth starts hurting? If this happens, it's crucial to take action immediately to prevent further damage. Follow these steps:
1. Rinse Your Mouth with an Antiseptic
To prevent infection, rinse your mouth with an antiseptic solution like Miramistin or Chlorhexidine (0.05–0.1%). This will help eliminate bacteria and reduce inflammation.
2. How to Temporarily Seal the Tooth?
You can temporarily cover the exposed cavity with cotton wool or gauze soaked in antiseptic to protect it from food and bacteria. However, this is only a short-term solution.
3. Can You Chew Without a Filling?
No! Chewing without a filling puts excessive strain on the exposed tooth, which may lead to fractures or further damage. Avoid chewing on the affected side.
4. Take Pain Relievers If Necessary
If you're experiencing pain, take an over-the-counter pain reliever such as Ibuprofen or Paracetamol (following dosage guidelines).
5. When Should You See a Dentist?
Visit your dentist as soon as possible after a filling falls out. Delaying treatment may lead to infection, further decay, or even more serious dental issues.
How Long Can You Go Without a Filling?
Even if your tooth doesn’t hurt, you shouldn't delay treatment. An open cavity exposes the tooth to bacteria, which can cause decay, inflammation, and even pulpitis. The sooner you see a dentist, the better.

How to Prevent Fillings from Falling Out?
To ensure the longevity of your fillings and prevent them from falling out, follow these guidelines:
1.Brush Your Teeth Regularly – Brush at least twice a day and use floss or an irrigator to remove food debris and bacteria.
2.Visit Your Dentist Twice a Year – Regular checkups help detect filling wear early and prevent dental diseases.
3.Avoid Hard Foods – Don't chew on hard foods (like bones or nuts) and never use your teeth as a tool to open bottles.
4.Maintain a Healthy Diet – Eat foods rich in calcium and vitamins to strengthen your teeth.
5.Use the Right Toothpaste – Opt for toothpaste that strengthens enamel and protects against cavities.
