###Human: My 3-year-old is not speaking properly. Can this be because of tongue tie? ###Assistant: Hi. The frenulum is a normal structure. It is only that when it attaches close to the tip, it causes problems with tongue rolling. Ask your child to protrude the tongue. If it causes buckling of the tip, it is tongue tie. And see if he is able to slip undersurface of the tongue tip underneath his upper teeth.
