Oral health and nutrition have a multifaceted relationship. Oral infectious diseases impact ability to eat and nutrition status. Likewise, nutrition and diet can affect the development and integrity of the oral cavity and progression of oral diseases. 1
- Dietary factors, primarily frequent consumption of simple sugars that feed decay-causing bacteria, initiate the caries process. 2
- Evidence supports a relationship between the amount of sugars ingested and the development of dental caries across age groups. 3
- Children who frequently consume sugar-sweetened beverages (SSBs) at age 10–12 months are far more likely than those who do not to have tooth decay at age 6, suggesting that infancy may be an important time to instill healthy beverage habits. 4
- Children from households with low or very low food security have significantly higher caries prevalence than children living in fully food-secure households. 5
- Oral health professionals can help children and their parents identify sources of added sugars and provide guidance to decrease intake of added sugars, thereby improving nutrient intake and reducing caries risk. 6
- Common risk factors associated with both obesity and dental caries include developmental conditions, socioeconomic status, acculturation, stress, and diet. These findings support a holistic approach in which interventions and policies target common risk factors, such as SSB intake, as a way to prevent multiple diseases. 7
- National attention is needed to help develop comprehensive feeding and oral health care policies for child care centers; such policies may help reduce the epidemics of childhood obesity and dental caries. 8
- Oral health professionals can work as part of an interprofessional team that includes registered dietitian nutritionists to improve oral health and overall health through provision of weight screening, obesity education, and intervention to children who are at risk for obesity. 9
- There are several challenges in improving nutrition teaching in dental education, including a lack of guidelines to assist in the development of core nutrition curricula, few trained faculty members teaching nutrition, few faculty members who can model and implement nutrition models in clinical settings, and a lack of rigorous research on the efficacy of clinical interventions. 10
- Many children with special health care needs (CSHCN) have restricted diets, and understanding the oral health implications of restricted diets can help the dental team better manage the needs of CSHCN. 11
- Higher maternal diet quality in the year before pregnancy is associated with lower risks for neural tube defects and orofacial clefts. 12
