I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
As you age it is important to keep up with good dental hygiene. The core part of good dental hygiene is brushing your teeth twice a day. This removes food particles and bacteria that causes tooth decay. Your tooth sensitivity may increase as you age. This can be minimized by using a soft toothbrush and desensitizing toothpaste. In addition to brushing your teeth, you need to clean between them. This can't be done effectively with a toothbrush. Instead, it is done with floss or a flossing device.
