3 Signs You Need A New Dental Filling

3 Signs You Need A New Dental Filling

Dental fillings are designed to be tough but will not last forever. The bond that holds the composite resin or metal filling in place will eventually weaken over time. This process can occur more quickly if you grind your teeth or do not take care of your oral health adequately. A loose filling can cause serious oral health complications such as tooth decay, heightened tooth sensitivity, or root canal infection. There are many signs that you might need a new tooth filling. Keeping up with at-home dental care while visiting your dentist for regular dental exams and dental cleanings will help make sure your mouth and smile are as healthy as can be. Here are a few signs that you may need to visit your dentist for a dental filling replacement. 

Increased Tooth Sensitivity

Is it uncomfortable drinking hot and cold beverages or eating sugary foods? A tooth filling insulates your tooth's inner nerves from drastic temperature changes and bacteria. When your tooth filling is damaged or loose, the delicate nerves in your tooth are exposed causing you pain and discomfort. When the filling is damaged, you are also inviting in tooth-decaying bacteria which can lead to more serious oral health problems. 

Discomfort When Chewing Food

If you constantly feel pain coming from your tooth with the filling, it could be a sign of a damaged or missing dental filling. Eating can place pressure on the filling, therefore, aggravating the tissue below. If food particles and bacteria creep under the filling, this can also cause serious discomfort. Even when you are not eating, you may constantly experience underlying sensitivity and discomfort coming from your filling. This is the biggest tell-tale sign that you have a problem with your dental filling and need to visit your dentist for a dental exam and filling replacement. 

The Contours Of Your Teeth Feel Different

Your tongue is finely tuned to detect any changes or disturbances in your teeth. If you find yourself more drawn to a particular tooth, it could be a sign that there has been a change in texture on that tooth. A change in texture could mean that your filling has been damaged, loose, or missing. You might also notice a problem when you bite down to close your mouth. These subtle changes and differences could be a hint that there is something wrong with your filling.

Q: How long do dental fillings normally last?
A: How long your dental filling will last will depend on how well you take care of your oral health, if you grind your teeth, and how often you visit your dentist for regular dental exams. Typically, a dental filling will generally last 10-12 years.

Q: How long is a dental filling procedure?
A: The length of the procedure will be determined by how many fillings you require and how serious your cavities are. An appointment can last anywhere from 20 minutes to an hour.

Q: What do I do if my dental filling falls out?
A: If your dental filling falls out or goes missing, book an appointment with your dentist right away to receive a replacement. If you leave the tooth without the filling for too long, bacteria can begin to cause tooth decay and serious tooth sensitivity and discomfort.
