6 Reasons Why Your Tooth Might Hurt After Filling

Some of the common reasons why your tooth hurts after filling are:


You can think of this type of sensation as the waves of the sea. It comes and goes every now and then, but it should disappear on its own. It’s activated by cold and hot foods or drinks (even cold air), candy, fruit, and biting down. If it’s been longer than a few weeks and you find yourself still experiencing these symptoms, give your dentist a call.


Inside of your tooth, there’s something called the “pulp.”You can think of your tooth as a house and the pulp as the family it protects from rain and wind. If bacteria manage to open a door and enter your tooth’s insides, it can cause an inflammation of the pulp.

It can also be the source of pain or sensitivity. The good news is that your tooth can be saved with a root canal treatment depending on the severity. If the pain isn’t going away, visit your dentist to get an examination.

3.-Referred pain

This type of pain comes from the teeth that surround the tooth with the filling. What happens is that your brain gets confused and sends the signals of pain from the filled tooth to other teeth instead. It should disappear in one or two weeks.

4.-Allergy to dental fillings

This allergy comes from the materials of the filling. It doesn’t happen too often, but some people could be allergic to silver fillings, for example, which could cause tooth pain. That’s why it is super important to let your dentist know of any allergies. Fortunately, this issue can be fixed by visiting your dentist to see other material options.

5.-A cracked filling 

This can happen right after you get your fillings or after several years with them. Fillings can become loose as well without good care. Besides, they’re unfortunately not forever and will have to be replaced at some point. In these cases, be very careful around the filled tooth and contact your dentist right away to get it fixed or replaced.

6.-Incorrect bite alignment

When the dentist puts the fillings in place, they have to make sure these line up with the other teeth. So if the fillings are too tall, you’ll likely feel the pain when you try to bite down or eat anything.

  • Thanks to the guide, tooth pain can be caused by several factors, such as a dental filling left unattended for years. My uncle mentioned that drinking cold water makes his teeth hurt at random. It might be a good time for him to visit a dentist for a checkup before this tooth problem gets worse.
