At what age should I worry about mouth breathing in my child?

Any age is worth mentioning to your dentist, but the jaw is most moldable between about ages 4 and 10. Bringing it up during a regular checkup in that window gives us the best chance to guide jaw development before growth slows down.

Can mouth breathing in children be reversed?

Often, yes, especially when it is caught early and the underlying cause, such as enlarged tonsils or allergies, gets treated. Once the airway is clear, myofunctional exercises can help retrain the tongue and lips to support nasal breathing again.

Does mouth breathing actually cause cavities?

It raises the risk. Saliva rinses away food particles and neutralizes the acid that causes cavities. A dry mouth from constant mouth breathing loses much of that overnight protection, which is why we often see more plaque buildup in these kids.

Should I take my child to a doctor or a dentist first?

Either is a reasonable place to start. If we notice signs during a regular checkup, we will coordinate with your child's doctor or refer you to an ENT as needed. There is no wrong door here.
