Cavities are a bacterial infection created by acids, that cause your teeth to experience a hole in them.

The more sugar you eat, the more acid you will create in your mouth, and the more acidic attacks your teeth are exposed to, the higher the risk of developing tooth decay.
你摄入的糖越多,你口腔里产生的酸类物质也就越多,牙齿也会随之遭受更严重的酸性侵蚀,造成蛀牙的几率也会更大.
