Limit the number of snacks that you eat. Each time you eat food that contains sugars or starches, the teeth are attacked by acids for 20 minutes or more.

If you do snack, choose nutritious foods, such as cheese, raw vegetables, plain yogurt, or a piece of fruit.

Foods that are eaten as part of a meal cause less harm. More saliva is released during a meal, which helps wash foods from the mouth and helps lessen the effects of acids.

Brush twice a day with a fluoride toothpaste that has the American Dental Association Seal of Acceptance.

Clean between your teeth daily with floss or interdental cleaners.

Visit your dentist regularly. Your dentist can help prevent problems from occurring and catch those that do occur while they are easy to treat.

How does the food you eat cause tooth decay?

When you eat, food passes through your mouth. Here it meets the germs, or bacteria, that live in your mouth. You may have heard your dentist talk about plaque. Plaque is a sticky film of bacteria.

These bacteria love sugars and starches found in many foods. When you don't clean your teeth after eating, plaque bacteria use the sugar and starch to produce acids that can destroy the hard surface of the tooth, called enamel. After a while, tooth decay occurs. The more often you eat and the longer foods are in your mouth, the more damage occurs.

What is plaque?

Many of the foods you eat cause the bacteria in your mouth to produce acids. Sugared foods, such as candy and cookies, are not the only culprits. Starches, such as bread, crackers, and cereal, also cause acids to form. If you snack often, you could be having acid attacks all day long. After many acid attacks, your teeth may decay.

Plaque also produces substances that irritate the gums, making them red, tender or bleed easily. After a while, gums may pull away from the teeth. Pockets form and fill with more bacteria and pus. If the gums are not treated, the bone around the teeth can be destroyed. The teeth may become loose or have to be removed. In fact, gum disease is a main cause of tooth loss in adults.

One way to prevent tooth decay and gum disease is by eating a balanced diet and limiting the number of between-meal snacks. If you need a snack, choose nutritious foods such as raw vegetables, plain yogurt, cheese or a piece of fruit.

How do I brush my teeth?

• Place your toothbrush at a 45-degree angle against the gums.
• Move the brush back and forth gently in short (tooth-wide) strokes.
• Brush the outer tooth surfaces, the inner tooth surfaces, and the chewing surfaces of the teeth.
• Use the "toe" of the brush to clean the inside surfaces of the front teeth, using a gentle up-and-down stroke.
• Brush your tongue to remove bacteria and freshen your breath.

How do I floss my teeth?

• Break off about 18 inches of floss and wind most of it around one of your middle fingers. Wind the remaining floss around the same finger of the opposite hand. This finger will take up the floss as it becomes dirty. Hold the floss tightly between your thumbs and forefingers.
• Guide the floss between your teeth using a gentle rubbing motion. Never snap the floss into the gums.
• When the floss reaches the gum line, curve it into a C shape against one tooth. Gently slide it into the space between the gum and the tooth.
• Hold the floss tightly against the tooth. Gently rub the side of the tooth, moving the floss away from the gum with up and down motions.
• Repeat this method on the rest of your teeth.
• Don't forget the back side of your last tooth.

People who have difficulty handling dental floss may prefer to use another kind of interdental cleaner. These aids include special brushes, picks or sticks. If you use interdental cleaners, ask your dentist about how to use them properly, to avoid injuring your gums.

What is the difference between a DDS and a DMD?

The DDS (Doctor of Dental Surgery) and DMD (Doctor of Dental Medicine) are the same degrees. The difference is a matter of semantics. The majority of dental schools award the DDS degree; however, some award a DMD degree. The education and degrees are the same.
