Nutrition and Oral Hygiene in Children: Essential Tips from the Pediatric Dentist for Optimal Oral Development
Children's oral hygiene is a primary concern for pediatric dentists and orthodontists, but to what extent do we understand the influence of nutrition on this aspect?
Beyond the obvious relationship between sugar and the risk of cavities, there is a world of recommendations that dental professionals can offer to ensure healthy oral development and neurodevelopment in children.
Here, we discuss how dentists can provide comprehensive advice, spanning from pregnancy to early childhood, to promote proper oral hygiene and neuromuscular development in their young patients.
1. From pregnancy: nutrition for fetal oral development

The role of nutrition in oral hygiene begins even before birth. During pregnancy, adequate nutrient intake is crucial for fetal oral development. One nutritional tip that dentists can give to expectant mothers is to consider consuming tryptophan in their diet, an amino acid found in foods such as turkey, chicken, eggs, and dairy products.
This nutrient is essential for the development of oral structures, such as the palate and facial muscles, and also plays a crucial role in the development of the fetal central nervous system.
2. Young children: vitamin D and calcium for bone and muscle growth
Early childhood is a critical period for bone and muscle development, and nutrition plays a fundamental role in this process. Pediatric dentists, as experts in children's oral hygiene, can provide valuable guidance to parents to ensure that their children get the essential nutrients needed for the proper development of their jaw, teeth, and orofacial muscles.
Importance of Vitamin D:
Vitamin D is essential for the absorption of calcium and phosphorus in the intestine. These minerals are fundamental for bone formation and strengthening. During early childhood, when children are experiencing rapid bone growth, vitamin D plays a crucial role.
- Sources of Vitamin D: The main source of vitamin D is sun exposure. When skin comes into contact with sunlight, it naturally produces vitamin D. However, the amount of sun exposure needed can vary depending on geographical location and season. In regions with long winters or cloudy climates, supplementation may be necessary under the supervision of a healthcare professional.
Role of calcium in bone and muscle growth:
Calcium is a fundamental mineral for the development of strong bones and teeth, but it also plays a role in the proper functioning of muscles, including the orofacial muscles necessary for chewing and swallowing.
- Sources of calcium: Dairy products, such as milk, yogurt, and cheese, are excellent sources of calcium. It is also found in foods such as almonds, broccoli, and fortified soy products. It is important to include a variety of these sources in your child's diet.
Oral development and long-term health:
By ensuring that children receive enough vitamin D and calcium in their early years, parents are directly contributing to healthy oral development. This not only includes the health of teeth and gums but also the development of the jaw and orofacial muscles, which impacts chewing, swallowing, and speech abilities.
3. Diet that promotes chewing, breathing, and swallowing

- Fibrous foods: A diet rich in fruits, vegetables, and whole grains strengthens chewing muscles and improves oral hygiene.
- Varied textures: Exposing children to different textures helps develop tongue and jaw coordination, essential for functions like speech.
- Nasal breathing: Parents should be aware of the importance of nasal breathing compared to oral breathing, as it affects oral moisture and prevents problems such as dryness and cavities.
- Healthy swallowing: The way children swallow food influences their oral and neuromuscular health. Pediatric dentists provide tips for efficient swallowing.
A pediatric dentist can advise families on choosing foods that promote healthy and coordinated oral development, contributing to essential functions such as speech and swallowing.
Among other topics that pediatric dentists can discuss with the parents of their young patients is the connection between sleep and oral health in children. To learn more about this, we invite you to read our related blog here.
Conclusion
In summary, nutrition plays a fundamental role in children's oral hygiene and neuromuscular development. Pediatric dentists are able to provide comprehensive advice that goes beyond cavity prevention. By considering nutrition from pregnancy to early childhood, dental professionals can significantly contribute to the oral development and overall well-being of their young patients.
By providing this comprehensive advice, not only are more effective dental treatments ensured, but children's neurodevelopment is also cared for, laying the foundation for lifelong oral hygiene.
