Manual toothbrushes should be replaced every three to four months, when the bristles look worn or splayed and after illnesses such as colds or flu.

Standard industry practise is to replace battery or electric operated toothbrushes every 2-3 months and Sonicare toothbrushes every 6-12 months; refer to recommendations included with the safety instructions when you purchase the toothbrush to be sure.

A toothbrush cover keeps the brush clean for on-the-go use and at home. GUM toothbrush covers contain triclosan, an antibacterial ingredient that is active for up to eight weeks to protect the brush between uses. Try to ensure that the cover is ventilated so that it keeps bristles dry and straight. Alternatively dip your toothbrush into an antibacterial mouthwash (such as GUM® Paroex Alcohol-Free Mouthrinse) on a weekly basis.

Comparisons have been made between power-assisted (electric) toothbrushes and manual toothbrushes to look at the ability of each to remove plaque and prevent or reduce calculus (tartar) buildup, thus reducing gingivitis (gum disease). These research studies have shown both powered and manual toothbrushes to be equally effective when used correctly. So probably, in practical terms, which brush you use is not the critical factor, but how you use it. The ADHA Web site (http://www.adha.

A normal toothbrush can help but a tongue scraper will more effectively dislodge and remove bacteria and food debris.

We recommend that adults replace their toothbrush every three to four months, when you notice the bristles looking worn, splaying or after illnesses such as colds or flu. Children's brushes tend to wear quicker because children may brush with uneven strokes or sometimes chew or bite on their brush.

Run your hand over a moving orbital sander while practicing your smile and repeating to yourself: "This is just mild discomfort." Drink a quart of any house paint, preferably white. Then have someone try to force a slinky down your throat while you force yourself to breathe through your nose. Get dressed in a paper tablecloth and stuff straws up your nose. Lie on a bus bench during the rush hour. Set your alarm to go off every ten minutes.

Replacing your toothbrush frequently helps reduce the transmission of bacteria which cause colds, flu, bronchitis, and upset stomach... not to mention cavities and gum disease. If you or anyone in your family gets sick, replace your toothbrush three times. Use a new one when you become ill, another when you begin to feel better, and a third after recovery.

The brand of the toothbrush is not as critical as the type of bristle and the size of the head. A soft toothbrush with a small head is recommended because medium and hard brushes tend to cause irritation and contribute to recession of the gums, and a small head allows you to get around each tooth more completely and is less likely to injure your gums.

Yes and no. You can use a regular soft toothbrush, but most orthodontists recommend an orthodontic-cut toothbrush, where the bristles in the middle are lower than the bristles on the edges and cut into a "v" shape. You can also use any electric toothbrush, such as a Sonicare or Oral-B Braun. These do an especially good job of cleaning your teeth. To floss your teeth, you don't necessarily need special floss.

It is important to change your toothbrush on a regular basis – at least every three months. This is because:

It’s important that your toothbrush can reach all the surfaces of your teeth. So a brush with a smaller head is generally better than one with a larger head. Whether you choose a toothbrush with a straight handle or not depends on the shape of your mouth and how easily you can manipulate the brush. It’s important to change your toothbrush regularly – at least every three months. Once the bristles become worn out of shape, they are much less efficient at plaque removal.

Whether you wear braces or not, tooth brushing is not only essential, but continues as the most effective way to assure clean teeth and good hygiene. With so many different types of brushes available, the basic rule of thumb is to select a soft brush that has rounded bristles. Hard-bristled brushes may damage tooth enamel or injure soft tissue and gums. Select a brush with a proper head. The correct size is better to reach difficult-to-clean areas which are more prone to collecting plaque.
