Sugar is the main cause of dental decay when there are bacteria present. More significant than the amount of sugar you eat is the frequency of consumption.
Probably the worst thing you can do to your teeth is to drink a soda and have a sip every few minutes over a long period of time; the same is true for snacking. It is recommended that if you want to have a snack or soda or juice it is better to have it after food, as dessert, or have it in one sitting. Eating or drinking something sweet over an extended period of time creates a constant supply of sugar for bacteria that causes tooth decay!
It is important to be aware of all the sources of sugar that are out there. It is not just everything that is sweet, but anything that can turn to sugar like pieces of bread. Cutting down your sugar intake is good for cavity prevention, as well as your general health.
But what about when you have to have sugar? The best way to avoid cavities is to prevent the sugar from staying next to your teeth. Brushing after eating sugar, rinsing your mouth with Fluoride mouth wash, or chewing sugarless gum can help. However, nothing has the effect of avoiding sugar!
Is there any kind of food that prevents tooth decay? Well, not really. Some people believed that chewing foods like apples and carrots may have some plaque removal effect, but they still contain some sugar so any advantage is not clear.
Another group of food that causes significant damage to teeth structure is acidic foods. If in frequent contact with teeth, things like lime, lemon, and grapefruit can cause serious irreversible damage (erosion) to your teeth.
Good nutrition plays a large role in your dental health.A balanced diet will help to boost your body’s immune system, leaving you less vulnerable to oral disease.
How often and what you eat have been found to affect your dental health. Eating starchy foods such as crackers, bread, cookies, and candy causes the bacteria in your mouth feed on it, they then produce acids, which attack your teeth for up to 20 minutes or more. Foods that stick to your teeth or are slow to dissolve give the acids more time to work on destroying tooth enamel.
• Starchy foods:
• Crackers
• Breads
• Cookies
• Candy
• Sticky/slow to dissolve foods:
• Granola bars
• Chewy fruit snacks
• Dried fruit
• Hard candy
Sticky and starchy foods create less acid when eaten as part of a meal. Saliva production increases at mealtime, rinsing away food particles, and neutralizing harmful acids.
Foods such as nuts, cheese, onions, and some teas have been shown to slow growth of decay causing bacteria in the mouth.
