Why Does My Dental Filling Hurt?

Man in pain with dental filling

Getting a dental filling once in a while is common and is said to be helpful to many patients who need to protect their teeth that have been damaged by cavities. However, some patientseven mentioned that they experience some slight discomfort or sensitivity after getting it—this feeling is common among many, and typically subsides after some time. 

But what if the pain doesn’t go away even though the treatment is meant to stop the pain that’s caused by cavities? 

Our dentists at Blue Gum Dental advise you to understand the causes of dental filling pain to help you determine if it’s a normal part of the healing process or if it needs a return visit to the dentist.  

Let’s take a trip towards why your dental filling might hurt and what you can do to ease the discomfort. 

Why Do You Need a Dental Filling in The First Place? 

A dental filling is a treatment used to restore a tooth that has been damaged by decay. 

During the dental filling procedure, the dentist removes the decayed part of the tooth and fills the space with a material like composite resin, silver amalgam, or porcelain. This not only restores the shape and function of the tooth but also prevents further damage. 

It’s important to understand that dental fillings are necessary when a tooth has developed a cavity. 

Cavities are caused by the buildup of plaque and bacteria on the surface of the teeth, which eventually wears down the enamel. If plaque and bacteria continue to grow on the surface of the teeth, cavities may lead to further tooth damage, infections, and even tooth loss. 

Getting a dental filling helps to stop the decay, protect the remaining tooth structure, and restore normal chewing function. So, if your dentist recommends you to get dental fillings, you might already have a cavity growing on your tooth, and this needs to be given some attention. 

Why Do I Feel Pain After a Dental Filling Treatment? 

While a dental filling usually provides relief, it’s no longer new to experience some pain after the treatment. However, there are some people who do experience pain even after quite some time. 

Let’s take a closer look at the common causes of pain after dental filling treatment: 

1. Tooth Sensitivity 

One of the most common reasons for you to feel pain in your dental filling is because of tooth sensitivity. After a filling, the tooth may be more sensitive to hot or cold foods and drinks—and sometimes, even air. 

This sensitivity usually occurs because the filling material doesn’t insulate the tooth as well as natural enamel. In most cases, this sensitivity fades within a few weeks as your tooth adjusts to the filling. 

What Can You Do? 

If the sensitivity is mild, try using toothpaste specifically for sensitive teeth. This may help reduce discomfort, but make sure to avoid very hot or cold foods for a few days after your filling. Plus, try to be gentle when brushing and flossing the filled tooth. 

2. Bite Issues 

Another common cause of pain after a dental filling is a problem with your bite. If the filling is too high, it can cause discomfort when you close your mouth or chew. Even a slight misalignment can lead to ongoing pain or pressure on the filled tooth. 

What Can You Do? 

If you notice that your bite feels “off” after a dental filling procedure, contact your dentist again to let them know about your concern. They can easily adjust the filling to ensure it fits properly with the above or bottom tooth, which should alleviate the discomfort. 

3. Pulp Irritation 

During a dental filling, the dentist may have to remove a significant portion of the tooth’s structure to clean out the decay. In some cases, the pulp—the soft tissue inside the tooth—may become irritated. This can result in pain or sensitivity, especially when pressure is applied to the tooth. 

What Can You Do? 

Pulp irritation usually resolves on its own within a few days. If the pain persists or worsens, it’s important to return to your dentist for a check-up. In rare cases, the tooth may need additional treatment, such as a root canal, to address pulp damage. 

4. Allergic Reactions to Filling Materials 

Although it’s uncommon, some people may have an allergic reaction to the materials used in their dental filling, particularly amalgam (silver) fillings. For those who are allergic to these materials, they may suffer from pain, swelling, or a rash around the filled tooth. 

What Can You Do? 

If you suspect an allergic reaction, contact your dentist right away to make sure it is addressed promptly. They can replace the filling with a different material that is better suited to your needs. 

Tips on How to Manage Pain After a Dental Filling 

Now that we understand that getting dental filling services may cause mild discomfort for a short while, there are different ways to manage the pain you might feel and help the healing process. Here are a few tips to reduce dental filling pain: 

1. Over-the-Counter Pain Relief 

If the pain may still be tolerated, you might find relief by taking over-the-counter pain relief, such as ibuprofen, to help ease discomfort. Be sure to follow the dosage instructions and avoid taking more than recommended. 

2. Avoid Hot, Cold, and Sticky Foods 

In the days after your dental filling procedure, it’s best to avoid extremely hot or cold foods, as these can trigger sensitivity. Sticky or chewy foods should also be avoided, as they may dislodge the filling or irritate the tooth. 

3. Use Toothpaste for Sensitive Teeth 

If you’re experiencing some sensitivity, using toothpaste for sensitive teeth may help reduce that sensitivity. These specific toothpastes work by blocking pain signals from the nerves in your teeth. 

4. Adjust Your Bite 

If you feel that the filling is too high or if your bite feels off, it might be best to return to your dentist. They can adjust the filling to ensure it fits properly with the rest of your teeth. 

5. Practice Good Oral Hygiene 

Maintaining good oral hygiene is essential for the longevity of your dental filling and preventing future decay. Brush and floss regularly to keep the area around the filling clean and healthy. 

When Should You See a Dentist? 

If these dental filling treatments do not help, it’s time to get an appointment with your dentist. Your dentist is the best person you can talk to in case you still have more concerns about your teeth.  

You should consider contacting your dentist if: 

  • The pain is persistent and doesn’t improve.
  • The filling feels too high, or your bite feels uneven. 
  • You experience intense pain when chewing or biting. 
  • There is swelling, redness, or unusual discharge around the tooth. 
  • The pain is accompanied by fever or other signs of infection. 

Remember, it’s important to address dental filling pain early to prevent further issues.
