Tooth fillings strengthen and protect teeth with cavities. Although tooth decay is preventable, cavities are one of the most common health problems among children, teenagers, and adult. Sugary drinks, frequent snacking, and poor dental hygiene all contribute to tooth decay. Left untreated, cavities can lead to severe pain, infection, and even tooth loss.
Prevention is key when it comes to tooth decay. But if your dentist has already found a cavity in your tooth and the roots aren’t affected, you will get a tooth filling to restore it to its full function. If decay has progressed too far into the tooth’s roots, your dentist will likely need to perform a root canal on the tooth rather than a filling.
