From the Guidelines
The most critical nutritional requirement for teeth is to limit the intake of free sugars to less than 10% of total energy, as excessive sugar consumption is a primary cause of dental caries, particularly in children. According to the World Health Organization (WHO) and the UK Scientific Advisory Committee on Nutrition (SACN) report on Health, Dietary Carbohydrates, the evidence base for this stringent limit on free sugars is based on the well-established relationship between the frequent consumption of sugar-containing foods and dental caries 1.
Key points to consider for optimal dental health include:
- Limiting the frequency of sugar-containing eating occasions to no more than four times daily
- Avoiding acidic sugar-containing drinks that contribute to the erosion of dental enamel
- Maintaining good oral hygiene to remove plaque
- Consuming fluoride in drinking water (1 mg/l) or toothpaste to reduce the cariogenic effects of sugar
- Being aware of the risks associated with high sugar intake, particularly in low socioeconomic groups and migrants, where the practice of allowing toddlers to have trainer cups or dummies containing sugar drinks is not actively discouraged 1.
In addition to limiting sugar intake, other essential nutrients for teeth include:
- Calcium and phosphorus, which form the structure of teeth
- Vitamin D, crucial for calcium absorption and utilization
- Vitamin K, which helps regulate calcium metabolism
- Vitamin C, supporting gum health and collagen production
- Fluoride, which strengthens tooth enamel by promoting remineralization and making teeth more resistant to acid attacks
- Protein, important for tooth development and repair
A balanced diet that includes dairy products, leafy greens, nuts, fish, eggs, citrus fruits, and fluoridated water can provide these essential nutrients, supporting tooth formation, mineralization, and ongoing maintenance of dental structures 1.
From the FDA Drug Label
The following adverse reactions are possible in individuals hypersensitive to fluoride: eczema, atopic dermatitis, urticarial, gastric distress, headache, and weakness Developing teeth of children under age 6 may become permanently discolored if excessive amounts are repeatedly swallowed.
The most important nutritional requirements for teeth are not explicitly mentioned in the provided drug label. However, it can be inferred that fluoride is crucial for teeth, as the label discusses the product's fluoride content and its potential effects on teeth.
- Fluoride is essential for preventing tooth decay and promoting oral health.
- The label warns against excessive fluoride consumption, particularly in children under 6, as it may cause permanent tooth discoloration. 2
From the Research
Nutritional Requirements for Teeth
The most important nutritional requirements for teeth include:
- Calcium: essential for the development and maintenance of healthy teeth and bones 3, 4, 5, 6, 7
- Vitamin D: plays a crucial role in calcium absorption and bone health, and is also important for tooth development and maintenance 3, 4, 5, 6, 7
- Phosphate: necessary for the formation of hydroxyapatite, the main component of tooth enamel 4, 5, 6
- Magnesium: involved in the formation of tooth enamel and the maintenance of healthy teeth and bones 5, 6, 7
- Vitamin K2: may contribute to the maintenance of skeletal health and tooth development 7
- Fluoride: important for the prevention of tooth decay and the maintenance of healthy teeth 6
- Protein: necessary for the development and maintenance of healthy teeth and bones 6
- Other nutrients: such as manganese, copper, boron, iron, zinc, vitamin A, vitamin C, and the B vitamins, which are also important for metabolic processes related to bone and tooth health 6
Key Findings
- Calcium and vitamin D supplementation can increase bone density and reduce the risk of osteoporosis and fractures 3, 5, 7
- Vitamin D deficiency has been linked to an increased risk of tooth decay and other oral health problems 3, 4
- Phosphate homeostasis is essential for maintaining healthy teeth and bones, and abnormalities in phosphate levels can lead to oral health problems 4, 5
- Magnesium deficiency can negatively impact bone and muscle health, including tooth development and maintenance 5, 7
- Vitamin K2 supplementation may improve bone quality and reduce fracture risk in osteoporotic patients, potentially enhancing the efficacy of calcium and vitamin D supplementation 7
