A broken filling can cause discomfort and pain, often leading to questions about whether this is a normal or serious issue. Understanding what happens when a filling breaks and how it affects the tooth can help you seek the right treatment. In this article, we’ll explore how a broken filling can lead to pain, the causes, and how you can manage it.
What is a Filling?
A dental filling is a material placed in a cavity to restore the tooth’s normal function and shape. Fillings are necessary when a tooth has been damaged due to decay or trauma. Common materials used for fillings include amalgam, composite resin, porcelain, and gold.
Fillings can last for many years, but they may eventually wear down or break. When this happens, the tooth is left vulnerable to further damage and may cause pain or sensitivity.
How a Broken Filling Can Cause Pain
When a filling breaks, it can expose the inner part of the tooth, known as the pulp. This area contains nerves and blood vessels, which can be sensitive to temperature changes, pressure, and other factors. The broken filling may allow bacteria to enter, leading to infection or inflammation inside the tooth.
The pain caused by a broken filling can vary depending on the severity of the break. In some cases, the pain may be mild and temporary. However, if the break is large or deep, it can lead to more severe discomfort.
Common Types of Pain from a Broken Filling
Sharp Pain – When biting or chewing, the exposed tooth may cause sharp, sudden pain. This type of pain usually happens when the filling breaks and the tooth is exposed to air or food.
Throbbing Pain – Throbbing pain is often a sign of infection. If bacteria have entered the tooth, it can cause an abscess or infection, leading to a constant, pulsing pain.
Temperature Sensitivity – A broken filling can make the tooth more sensitive to hot or cold foods and drinks. This is because the pulp of the tooth is exposed, making it more sensitive to temperature changes.
Pain When Touching – If the broken filling has caused damage to the tooth’s nerve, touching the tooth, even lightly, may trigger pain.
Causes of a Broken Filling
Several factors can lead to a filling breaking. It’s important to identify the cause to prevent further damage. Here are some common reasons for a broken filling:
1. Wear and Tear
Over time, the materials used in fillings can break down due to normal use. Teeth are used every day for biting and chewing, and fillings naturally wear out. This wear can lead to cracks or breakage.
2. Biting Hard Objects
Biting down on hard objects such as ice, popcorn kernels, or pens can put pressure on a filling, causing it to crack or break. This is particularly common with fillings made of composite materials or older fillings.
3. Tooth Decay
If a filling becomes compromised due to ongoing tooth decay, it may break. The decay weakens the surrounding tooth structure, which can cause the filling to become loose or break away.
4. Trauma or Injury
Accidents that involve a direct hit to the mouth, such as a fall or blow to the face, can lead to a broken filling. This type of injury often results in more serious damage to both the filling and the tooth.
5. Teeth Grinding (Bruxism)
Grinding your teeth, often during sleep, can put pressure on fillings and cause them to break. This habit can also damage the enamel of your teeth, leading to additional dental problems.
What to Do If You Have a Broken Filling
If you discover that your filling has broken, it’s important to take action quickly to prevent further damage or pain. Here’s what you should do:
1. Assess the Pain
If the broken filling is causing severe pain, contact your dentist immediately. A dentist can determine whether there is an infection or if additional treatment is needed. If the pain is mild or there is no pain, you may be able to wait for a dental appointment but should still seek care soon.
2. Keep the Area Clean
After a filling breaks, food and bacteria can enter the exposed tooth. It’s important to keep the area clean. Rinse your mouth with warm saltwater to reduce the risk of infection. Avoid chewing on the side with the broken filling.
3. Temporary Fillings
Some pharmacies offer over-the-counter dental materials that can be used as a temporary filling. These materials help cover the exposed tooth until you can visit your dentist. However, this is only a short-term solution, and you should see your dentist for a permanent fix.
4. Avoid Certain Foods
Until your dentist can assess the damage, avoid eating hard or sticky foods that can irritate the exposed tooth. Hot or cold foods and drinks may also trigger sensitivity or pain.
How a Dentist Repairs a Broken Filling
When you visit your dentist for a broken filling, they will first assess the damage to the tooth. The process for repairing the filling depends on the extent of the damage.
1. Cleaning the Tooth
The dentist will clean the affected area to remove any debris or bacteria. This step is important to reduce the risk of infection and ensure the new filling adheres properly.
2. Removing Old Fillings
If the filling is severely damaged or decayed, the dentist may need to remove the old filling completely. This will allow them to assess the condition of the tooth and make sure it is properly prepared for a new filling.
3. Filling the Tooth
The dentist will choose the appropriate filling material based on your needs and preferences. If the filling is large, a crown may be recommended to restore the tooth’s shape and strength.
4. Follow-up Care
After the new filling is placed, the dentist will check the fit and comfort of the filling. They may schedule a follow-up visit to ensure that the filling is functioning well and that no further issues arise.
Preventing Future Breakage of Fillings
While some breakages are unavoidable, there are steps you can take to prevent your fillings from breaking prematurely.
1. Avoid Hard Foods
Be mindful of what you bite. Avoid chewing on hard objects such as ice or candy that can put pressure on fillings. If you have a habit of biting hard foods, consider using the other side of your mouth to chew.
2. Wear a Mouthguard
If you grind your teeth at night, a mouthguard can help protect your fillings. A dentist can custom-make a mouthguard to fit your teeth, reducing the pressure on fillings and preventing them from breaking.
3. Regular Dental Visits
Regular checkups allow your dentist to monitor the condition of your fillings. Early detection of wear or damage can help prevent more serious issues later on.
4. Good Oral Hygiene
Maintaining good oral hygiene is crucial for the longevity of your fillings. Brushing your teeth twice a day, flossing, and using mouthwash can help prevent tooth decay and damage to fillings.
Conclusion
A broken filling can cause discomfort and pain, especially if the tooth is exposed to bacteria or air. The pain may vary from sharp to throbbing, depending on the severity of the break. Immediate dental care is essential to prevent further damage, infection, and prolonged discomfort.
By understanding the causes of a broken filling and the necessary steps to manage it, you can reduce your risk of complications. Always visit your dentist promptly if you notice any signs of a broken filling to ensure that the problem is addressed before it gets worse.
Taking care of your fillings and maintaining regular dental visits will help you enjoy long-lasting oral health and prevent unnecessary dental pain in the future.
