Brushing

Brushing is a common oral hygiene practice, yet many people don't do it correctly. Dentists recommend you brush at least twice a day and after meals. After eating, sugars and carbohydrates from food left on teeth combine with the bacteria in your mouth. This produces acids that attack your teeth, leaving you susceptible to tooth decay. A good tooth cleaning after eating will help remove dental plaque bacteria and reduce your chances of getting dental cavities.

Learning how to brush properly is vital. For proper brushing techniques, hold your toothbrush at a 45-degree angle towards the gums. Brush in a back-and-forth motion, making sure to reach every surface of each tooth. And don't forget the tongue -- brushing the tongue will further remove the bacteria that cause bad breath! Your toothpaste may also play a role in the success of your oral hygiene routine -- since there are several toothpastes to choose from, it's best to ask your dentist which will benefit you. The American Dental Association recommends brushing with fluoride toothpaste to greatly reduce dental plaque bacteria.

Remember, a great rule to live by is to brush longer, not harder. You should brush for at least two minutes to remove as much dental plaque as possible. Harder brushing won't actually get teeth cleaner -- it can irritate the tissues in your mouth and actually cause gum damage! Use a soft-bristled toothbrush to protect your gums, and be sure to replace your toothbrush every three months.

Flossing

No matter how well you brush, there are some areas you just won't be able to reach. Flossing removes dental plaque that's hiding in between teeth. Learn how to floss properly with these tips: Start by holding the floss securely with each hand, and ease the floss between teeth. Gently rub the floss up and down, and curve it towards each tooth to cover more surface area. Once you reach the top, slide it under your gum line to remove plaque from beneath the gums. And be sure to use a fresh section of floss for each tooth -- you don't want to put food particles and bacteria back in your mouth!

Flossing at least once a day is recommended to remove the ongoing accumulation of dental plaque that forms between teeth. If you have trouble flossing, dental products are available to help -- waxed floss makes for easier maneuvering and floss holders assist those who have trouble handling the stringy material.

Diet

You're probably surprised by this one! But healthy eating habits are an equally important part of your oral hygiene regimen. Since sugars and carbs promote tooth decay, the more you eat, the better chances you have of ruining your teeth! Instead, focus on protecting your oral health by eating nutritional foods.
