Pregnancy and Your Child’s Developing Teeth
Wylie, Texas
A baby's teeth form underneath the gums before birth. Children's primary teeth begin forming at about the sixth week of pregnancy, and start mineralizing around the third or fourth month of pregnancy.
Key Nutrients for Prenatal Tooth Development
Calcium
The main tooth component. If dietary intake is insufficient, the body draws from maternal bones to support fetal needs. Sources include dairy products, broccoli, and kale.
Phosphorous
Balances calcium levels and contributes to tooth hardness. Found in dairy, red meat, poultry, seafood, legumes, and nuts.
Vitamin D
Enables calcium absorption and utilization. Present in salmon, tuna, and fortified beverages. The body naturally produces it through sun exposure, though supplementation may be recommended.
Protein
Builds and maintains tissues. A specific protein enables calcium-phosphate crystals to form tooth enamel rather than bone. Meats and dairy are protein-rich; vegetarian diets require careful food combining for complete amino acids.
Medications to Avoid
- Tetracycline antibiotics - Can permanently stain developing teeth
- Fluoride supplementation - Not recommended during pregnancy due to insufficient safety data
Consult healthcare providers before starting new prescriptions during pregnancy.
