Exposure to Drinks with Sugar
Even though bottles and sippy cups are convenient and good at preventing spills, they sometimes contribute to tooth decay in toddlers. The problem is that many parents fill these bottles and cups with sugary drinks like juice or soda. Cut back on the risk of tooth decay by only filling your toddler's bottles and sippy cups with water, breast milk or formula.
Some parents let tots carry something to drink so that they have constant access to the drinks. While this may seem like a great way to calm a fussy toddler, it can actually expose your child's teeth to damaging substances over an extended period.
You should also avoid giving your toddler a bottle or sippy cup when you tuck him in for nap time or bedtime. Because the mouth tends to dry out during sleep, anything your child drinks before bed is more likely to stick to his teeth, increasing the chance that tooth decay will occur.
The American Dental Association (ADA) notes that sippy cups should only be temporary tools for children, so you should aim to teach your toddler to drink from a big kid's cup by his first birthday.
