What is a tooth filling?
A cavity is a hole left behind by dental decay. If left untreated, the damage from the cavity will continue to spread to the surrounding teeth. During a dental filling procedure, dentists clean the decay inside the cavity before filling it with a special material.
Dental cavities were once filled with metals, such as silver or gold. However, now most of our dental fillings are done with composite resin materials. These materials are not only safe, but also blend in with the natural color of your teeth.
When does a cavity need to be filled?
A dental filling is usually suggested for small cavities with minor decay. A simple toothache is the most common sign you need a filling, but there are other signs to look out for as well. This includes sensitivity to hot and cold temperatures, pain when biting down or chewing, and a visible hole you can see or feel in your teeth.
Even though tooth-colored fillings are generally long-lasting, it is important to attend regular dental exams to ensure the procedure remains successful.
