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 prone to bleeding. After a while, the 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, periodontal (gum) disease is a main cause of tooth loss in adults.
One way to prevent tooth decay and periodontal 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.
