Can listerine destroy fillings

Listerine and other mouthwashes typically do not destroy dental fillings, but they can affect certain types of fillings over time, especially if they contain materials sensitive to alcohol or strong ingredients. Prolonged exposure to alcohol-based mouthwashes may lead to degradation of some composite materials. However, regular use as directed is generally safe for most dental work. If you have concerns, it's best to consult with your dentist.
