How to have a great smile
Brush your teeth correctly.
The single most important thing you can do to keep your teeth healthy is to brush them two to three times a day, using the proper technique. A lot of people fall short in this area, so make sure you understand exactly how you should be brushing your teeth.
Each time you brush your teeth, you should brush for approximately two minutes. Try using a timer to help you get the timing right.
