A tooth filling is used to repair the structure and restore the function of a tooth which has been affected by cavities, tooth decay or physical damage. It works by filling the space with a material such as composite resin, amalgam, gold or porcelain. A filling protects your tooth from further decay, sensitivity and infection.
Losing a tooth filling, especially at night, can be a stressful and uncomfortable experience. The tooth becomes exposed and vulnerable to further damage, making prompt action essential.
A lost filling is considered a dental emergency and requires immediate medical attention, whether you are in any pain or not.
In this guide, we will walk you through the emergency tips and steps you should take until you can see a dentist to address the issue and restore your tooth to its healthy state.
Immediate Actions to Take
If your tooth filling has fallen out then it is important that you take immediate action. Firstly, you need to find out whether the filling has dislodged completely or if it is partly broken. You should also be aware of any pain, sensitivity or discomfort that you may be experiencing and inform your dentist so that they can provide you with the most appropriate advice and schedule an appointment as soon as possible. If you can find the filling then it is worth taking it to your dentist who can inspect it to understand why it may have fallen out and decide the most effective treatment plan.
It is important to clean the affected area gently right after the filling falls out. Rinse your mouth with warm salt water to remove any lingering food particles and also to help reduce the risk of infection. You can gently brush the area with a soft-bristled toothbrush, to ensure continued oral hygiene.
Temporary Pain Relief Methods
You may experience some pain or discomfort after your filling has fallen out. Over the counter pain medication including nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, are effective in minimising pain and swelling. These medications work by reducing inflammation, offering quick relief until your appointment.
Clove oil is a natural alternative for temporary pain relief. The active ingredient, eugenol, possesses analgesic and anti-inflammatory properties, helping to numb the nerve endings and reduce pain. Mix a few drops of clove oil with a carrier oil, such as coconut or olive oil, to prevent gum irritation, and apply it to the affected tooth or gum for a few minutes for immediate pain relief.
If you are experiencing sensitivity then you may wish to consider a temporary filling until you can visit your dentist. These can be found at pharmacies and resemble a soft putty which hardens inside the mouth. First clean and dry the affected area and then roll the filling material into a ball and place it on the tooth. Using your finger, mold the putty onto the tooth. It will then harden, and can help reduce pain and sensitivity, and protect the tooth until you visit your dentist.
Preventing Further Damage
Avoid Certain Foods and Beverages
It is important to avoid certain food and drink to reduce any discomfort and prevent further damage to your tooth after losing a filling. It is important to avoid hot or cold foods and drinks, as the exposed nerves of the tooth can be highly sensitive to temperature changes. You should consume food and drinks at room temperature until the filling is replaced. Also avoid hard, crunchy, or sticky foods that could seep into the cavity or cause further irritation. Opting for soft, easy-to-chew foods can prevent further discomfort and protect the tooth from additional damage.
Chew on the Opposite Side
Chewing on the side of the mouth where the filling has fallen out can cause damage to the affected tooth. To avoid this, make a conscious effort to chew your food on the opposite side of your mouth. This can also help minimise existing pain or sensitivity. By distributing the chewing forces evenly on the other side, you can protect the exposed tooth until you can see your dentist.
Keep the Area Clean
As always it is important to maintain good dental hygiene but if a filling has come out then it is important that you take extra care with keeping your mouth clean. This is to help avoid bacterial build-up and the risk of infection. By using a soft bristled brush to brush your teeth gently, twice a day and especially after meal times, and rinsing your mouth with salt water you can help prevent further decay and ensure the tooth remains healthy until it can be properly treated by your dentist
Don’t Delay!
Losing a tooth filling can be worrying and is often accompanied by pain and sensitivity. It is important that you speak to your dentist to book an appointment as soon as possible to have your filling replaced to avoid the risk of tooth decay or further damage to your tooth. During this time it is important that you maintain excellent dental hygiene to avoid the risk of infection and also to adjust your diet to avoid discomfort or sensitivity. Pain and sensitivity can be managed by taking over the counter medication or you may wish to consider a temporary filling.
Speak to your dentist as soon as possible so that your filling can be replaced and you can continue to enjoy good dental health and overall well-being.
