2. What Factors Affect How Long Tooth Fillings Last?
When asking, “How long do tooth fillings last?” you should also ask yourself, “What am I going to do to extend the lifespan of this filling?” Believe it or not, your actions do play a role. After all, your lifestyle choices can impact your intact natural teeth, and the same is true of your restorations.
Oral Hygiene Habits
Getting a dental filling doesn’t mean that you won’t have to worry about decay in the tooth in the future. Brushing and flossing regularly are key to preventing decay near your fillings.
Dietary Choices

Teeth Grinding
Grinding your teeth or clenching your jaw at night, a condition called bruxism puts extra stress on fillings, particularly amalgam or composite ones. Hunt Family Dentistry can provide you with a custom night guard to protect your teeth and jaw.
Regular Dental Checkups
Even though we take care of your dental decay with the filling, we still need to check up on it and your surrounding teeth. Routine checkups help catch and fix minor filling issues early.
Chewing on Hard Objects
You might have the nervous habit of chewing on ice, pencils, or your nails. While understandable, if you chew on these items around your filling, you could be putting it in jeopardy. In fact, your natural teeth aren’t safe from this damaging habit either. Try to avoid nibbling on non-food objects.
2. How Do I Know If My Dental Filling Needs to Be Replaced?
No matter how long tooth fillings last, there will likely be a time you need to replace them. They’re not designed to last forever. Watch out for these signs:
- Pain or Sensitivity: A persistent ache or sensitivity when eating hot, cold, or sweet foods could mean the filling is worn or cracked.
- Cracked or Chipped Filling: Visible damage or changes in the texture of your tooth are clear signs you need an evaluation.
- Discoloration: If you notice dark spots or staining around the filling, that could suggest decay beneath it.
- Gaps Between Fillings and Teeth: If your filling no longer fits snugly, bacteria may enter and cause damage.
- Food Stuck Frequently: If you feel like something is constantly getting stuck around the filling, it could signal that it’s loose or no longer effective.
