I struggle to get my DS to brush his teeth. The dentist advised limiting foods which were particularly bad for his teeth such as fruit, sugar, honey and carbohydrates like bread, pasta, potatoes, cereal, porridge, whole grains (wheat, corn, oats, maize, barley, rye, millet, quinoa, spelt, rice) beans, chickpeas, lentils, nuts, parsnips, root vegetables, yams, peas, squash, sweet potato.
He encouraged us to increase protein and fibre intake and also the amount of green vegetables that he eats.
