Apples and other fresh fruits are very good for the teeth. Although they are also sweet and acidic, they do not cause any problem because chewing them stimulates saliva flow. Saliva will decrease mouth acidity and wash away food particles.
Apples have also been called nature’s toothbrush because they would increase saliva flow, stimulate the gums, and reduce the build-up of bacteria that is causing cavity. If you have a chronically dry mouth, it will also contribute to tooth decay. According to studies, saliva usually flows slowly during our sleep, so going to bed without brushing our teeth is very harmful.
