Electric toothbrushes are the best way for kids to clean their teeth. Electric toothbrushes move on their own, and they do so in a way that helps to loosen and eliminate food and plaque. This helps ensure that their teeth are clean.
If you find that your mouth and lips are dry a lot, tell your dentist about it. If you are taking medications, they may be the cause. Your dentist will be able to tell you whether your medications are causing your dry mouth, and can help you determine how you can treat it.
Chew some sugarless gum after each meal. The motion of chewing encourages the production of saliva which works as a wash for your teeth. Any sugars from foods that you have eaten can effectively be washed away. This is a good way to keep your teeth clean between meals if you cannot brush.
Be sure to get any chips or cracks in your teeth as soon as possible. When you have a cracked or chipped tooth, you are giving germs and bacteria a great place to hide. Obviously, when you have these problems fixed, bacteria and germs have nowhere to go. Fluoride mouthwash can also help.
