Dental fillings are designed to protect your teeth, but over time, they can wear down or break. Acting quickly when you notice a problem can prevent a minor issue from becoming a major dental concern.
Fillings are built to last—some materials can last decades, while others may need replacement sooner. Composite resin fillings are more common than gold or silver amalgam but typically have a shorter lifespan. With proper care, composite fillings can last over 10 years.
Why Fillings Break?
Dental fillings can become loose, crack, or fall out due to several reasons:
- Decay in the tooth where the filling is placed
- Fractures or breaks in the filled tooth
- Trauma or a hard impact to the mouth
- Bad habits like chewing ice, bottle caps, or other hard objects
When a filling breaks, it exposes the inner tooth to pressure, temperature changes, bacteria, and food debris. This can cause discomfort or even pain, signaling that it’s time to visit your dentist.
Signs of a Cracked Dental Filling
Fillings act as barriers protecting your teeth. When a filling cracks or breaks, the tooth’s vulnerable inner layers are exposed. Watch for these signs:
- Sensitivity: Food, drinks, or air reaching the inner tooth can cause temporary discomfort. Rinsing may help relieve irritation.
- Audible crack: Sometimes, you can hear and feel the exact moment a filling fractures.
- Pain from pressure: A cracked filling can make your tooth sensitive to chewing or biting, causing discomfort that subsides when pressure is removed.
- Detectable rough edges: When touched with your tongue or a finger, you may feel sharp or uneven edges on the tooth.

FAQs About Dental Fillings
Is mercury used in dental fillings?
Silver amalgam fillings contain a mixture of metals, including mercury, which makes up about half of the material. While mercury is toxic in high amounts, the FDA considers amalgam fillings safe for people over six years old. Composite resin fillings, which are mercury-free and color-matched to your natural teeth, are now the most popular and aesthetically pleasing choice.
Can cracked dental fillings cause bad breath?
Yes. A damaged filling allows bacteria and debris to enter the tooth, potentially leading to decay. This can produce foul-smelling sulfur compounds, causing bad breath, which worsens if the tooth becomes infected.
How long do dental fillings last?
The lifespan of a filling depends on the material used. Fillings can last up to 10 years or more, but they are not permanent. Bite forces and wear gradually reduce their effectiveness over time.
