Sippy Cups and Toddler Tooth Decay

Many pediatric dentists believe that frequent, prolonged use of sippy cups can contribute to toddler tooth decay. While sippy cups are excellent tools for transitioning from baby bottles to adult cups, their convenience often results in overuse, sometimes well into late toddlerhood. As a result, “baby bottle cavities” are increasingly common in children aged two to five.

The American Academy of Pediatric Dentistry (AAPD) recommends a well-baby checkup around six months after the first tooth emerges. During this visit, pediatric dentists educate parents about sippy cup use, oral care routines, and strategies to prevent unwanted habits.

When Should My Child Use a Sippy Cup?

Sippy cups should be introduced when the child is physically able to grasp them and discontinued once the child can use an adult cup, usually around one year of age. Since the first teeth are at risk for decay as soon as they emerge, early oral care is crucial.

Pediatric dentists advise parents to follow these guidelines during the sippy cup period:

  • Use water in sippy cups instead of sugary liquids whenever possible.
  • Remove the cup once the child has finished drinking; avoid continuous sipping.
  • Do not allow sippy cups at bedtime unless they contain water.
  • Do not use sippy cups to comfort a child, especially with sugary liquids.
  • Rinse the sippy cup frequently to eliminate germs.
  • If sugary drinks are necessary, offer them only at mealtimes when saliva production is highest.

How Do Sippy Cups Cause Tooth Decay?

Sippy cups themselves do not cause decay. The problem arises when they are filled with sugary liquids, such as breast milk, formula, juice, soda, or sweetened water. Because sippy cups release small amounts of liquid at a time, sugars remain in contact with the teeth for prolonged periods. Oral bacteria feed on these sugars and produce acids that attack enamel, making teeth susceptible to cavities. Some cavities may form between teeth and be difficult to see, making biannual dental visits essential.

Choosing the Right Sippy Cup

The American Dental Association (ADA) recommends the following:

  • Avoid no-spill valves, which only release small amounts of liquid and increase sugar exposure in the mouth.
  • Choose cups with a spout, preferably snap-on or screw-on lids, to promote proper sipping habits.
  • Two-handled cups are preferable, helping the child transition to adult cups that require both hands.
