If you have sensitive teeth, you should use a toothpaste designed for this specific problem. One common sign of sensitive teeth is feeling pain or discomfort upon eating food that is unusually hot or cold. You must be sure that you talk to a dentist when this occurs so you're sure it's not something more serious.

You must brush your teeth and your tongue. Leaving food particles to collect on your tongue allows germs and bacteria to breed there. This can contribute to bad breath, in addition to poor dental health.
