Patients are often surprised to hear that their fillings won’t last forever. Although composite resin fillings can last for decades, they are not permanent and will wear down over time. Here is what patients should know about resin fillings and what to do if the filling fails.
What Are Resin Fillings?
Tooth fillings can be made from a variety of materials, such as gold, silver, porcelain, or resin. They are used to restore cracked or broken teeth and re-strengthen teeth after removing a cavity. At South Meadows Dental & Orthodontics, we offer composite resin fillings, which are made from a tooth-colored material that blends seamlessly into the tooth, providing a great cosmetic finish.
What Does It Mean When a Filling Fails?
Fillings have earned their name because they fill in cracks or deep grooves in teeth. This seals off the underlying layers of the tooth and strengthens it for proper biting and chewing. A failed filling no longer has proper sealing, which means the inner layers of the tooth and its roots are exposed to bacteria. Bacteria exposure can cause an infection and further tooth decay if the worn-down filling is left untreated.
What Causes a Resin Filling to Fail?
Resin fillings wear down or crack over time because of biting force and pressure. Although less common, the resin material can also shrink after placing it. Shrinkage creates a gap between the filling and the teeth, creating an opening for bacteria. As the resin shrinks, it also pulls on the tooth structure, placing stress on the tooth that can damage it over time.
How to Repair a Failed Resin Filling
If a tooth filling breaks down, repairing it as soon as possible is important to keep the tooth protected. Repairs can be done with the placement of another filling or a crown. First, the existing filling material must be removed to examine the tooth’s inner layers and check for signs of infection. The tooth will be cleaned if needed, and then a new filling will be placed.
Dental crowns serve a similar purpose but are placed like a cap over the tooth. We offer crowns made from porcelain, composite resin, and porcelain fused to metal. At your appointment, your dentist will discuss these options with you and examine your tooth to determine the best course of treatment.
