Effective Oral Care. When the bristles of your toothbrush are worn down or frayed, they will not do an effective job of cleaning your teeth. Bristles on an old toothbrush are also not as effective at cleaning between your teeth and along the gum line.
Oral And General Health. The bacteria from your mouth is transferred to your toothbrush. Even if you clean your toothbrush after you use it, some of the bacteria can remain. The bacteria can return to your mouth the next time you brush your teeth.
Bacteria is harmful to your oral health, and it can be dangerous to your general health, too. Bacteria in your mouth can spread throughout your body, and cause serious health problems.
Replacing Your Toothbrushes. It is a good idea to buy a new toothbrush after you have had a cold, the flu, cold sores, or any illness affecting your mouth. Some people brush more vigorously, and may also need to replace toothbrushes more frequently.
If you have been using the same brush for many months, treat yourself to a new one. You can ask your dentist if the size and style is right for you. Your dentist can also help you decide whether to buy a manual toothbrush or an electric toothbrush.
As your oral health and your general health are important, do not use the same toothbrush for more than a few months. If you cannot afford an expensive style, basic toothbrushes cost only a couple of dollars. It is worth the time it takes to shop, because a fresh new toothbrush will help you maintain good oral health.
