When Should Your Child Stop Using a Pacifier?

As a parent in Carrollton, TX, you’ve probably wondered: when should your child stop using a pacifier? It’s one of the most common questions we hear at Flink Family Dentistry. Pacifiers and thumb sucking are completely normal in infancy. But as children grow, these habits can start to affect their developing teeth and jaws.
