A relationship exists between oral health, diet and nutrition. Diet and nutrition affect the health of the teeth, and the health of the teeth affects nutrients consumed. An unhealthy diet can increase the risk of cavities (tooth decay or dental caries), gum disease and obesity. Food and drinks containing sugar and starches cause the harmful bacteria in the mouth to form an acid that weakens the tooth enamel, the protective outer layer of the tooth. Over time and without proctective factors, the enamel can be destroyed and cavity can form.

Some sugary foods and drinks increase the risk for cavities. Other foods prevent the development of cavities and protect the teeth. 

Foods to avoid:

• Sticky candies and sweets: syrups, yogurts, ice cream, snack foods, cookies and other sweet baked goods
• Sugar-sweetened beverages: soda, flavored milk, sports and energy drinks, coffee, tea, juice and fruit drinks
• Refined carbohydrates: white flour, white bread, white rice, pastries, pasta, potato chips, processed foods
• Alcoholic beverages 

Foods to eat:

• Fruits, especially whole fruits, and vegetables   
• Whole grains: whole-wheat bread and pasta, brown rice, quinoa
• Fat-free or low-fat dairy: milk, plain yogurt, cheese
• Protein foods: seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts and seeds
• Water, especially fluoridated water

Childhood obesity is a major public health problem. Nearly 20% of US youths aged 2 to 19 years are obese. Obesity levels are disproportionately high in ethnic minority, low-income, and other socially marginalized groups. Tooth decay or cavities is another common condition affecting children. In the United States, tooth decay is the most common chronic disease among youth aged 6–19 years with higher rates among low-income children. If left untreated, it can cause pain and infection leading to problems with chewing, swallowing, speaking, and learning. Common risk factors for obesity and cavities are the frequent consumption of sugar-sweetened beverages and frequent snacking on carbohydrate-rich foods. 

Dental providers have an important role in the diagnosis of oral diseases correlated with diet. Consistent guidelines on nutrition and oral health are essential in improving overall health. Florida's Not So Sweet Tooth Campaign* aims to reduce childhood obesity and tooth decay by providing dental providers and public health professionals with effective resources to address these health issues with their patients. Funded by the Health Resources and Services Administration, the Not So Sweet Tooth Campaign toolkit includes webinar presentations, handouts, and other resources for dental providers to use in their clinical practice.
