We found out our daughter was tongue-tied at age 4 1/2 (she is now 5 1/2). She was having trouble saying certain words/sounds, and I thought to myself, I just don't think that she has the ability to say certain things. Our dentist had told us at age 3 that she was just a little tongue-tied (our son had the same evaluation at age 3). The dentist reccommended that we wait and see if he outgrew it, a lot of times it is corrected as kids grow. His did correct itself. He never had trouble eating as a baby or with speech ever. But, our daughter just could not say certain sounds (she ate like crazy as a baby and never had problems eating ever.) So, we had her evaluated by a speech therapist through our school system, as our doctor recommended. She was 1 point away from needin speech therapy. i asked our doctor what the next step was because I just knew something was not right. He said we could see a speech pathologist (someone with a more advanced degree and who knows more about mouth/tongue structure and speech therapy.) We went to our local hospital for an evaluation. Right away without me saying anything, she indicated that our daughter's mouth/tongue would just not be able to say certain sounds clearly because her "tongue was too tightly attached to the bottom of her mouth." She recommended an ENT do the "simple" surgery. It just takes 5-10 minutes, HOWEVER, it does require that the child be PUT ALL THE WAY UNDER, because kids this age can squirm, be scared, etc., and the ENT wants the surgery to be precise!!!! (if they notice it with a baby, it is a very simple cut, not even bleeding, something to do with a newborn/baby not having developed this area of the mouth yet, that is why previous posters indicated it was over in minutes) So, we lamented so long over this .... we did not want her to be put all the way under, it made us nervous. But, after agonizing, we decided to do the surgery. We wanted her to be able to talk well, also eat popscicles and ice cream without making a mess, and later in life (much later!) be able to kiss comfortably. But, talking was the major reason.... thinking that self-esteem develops a lot from how you interact with others and how they react to you - we wanted her to be able to be the best she could be, and believed this surgery would help her say her sounds better (big brother and a neighbor were already calling to her attention that she was "talking funny".) I was nervous as I waited for the surgery to be over, but all went well. Within days she was able to say those sounds pretty well!!! Results vary the speech pathologist said..... some kids need more therapy than others. We did do therapy for about 8 weeks after. It was helpful, too. Now our daughter can say all those sounds that she could not say before!!! A few months ago our newphew was diagnosed with the same, and my sister went to an ORAL SURGEON (previous poster said Dentist, but a dentist can't perform this procedure)..... but, Oral Surgeons can do it, too. Our newphew (age5) did not need to go all the way under (only an anesthesiologist can do that anyway), and everything went well for him. I found out about the Oral Surgeon option a few days before our daughter's surgery was scheduled, and at that point, we had everything already set, but if I was doing this again, I might go the Oral Surgeon route just because she would not have had to go all the way under. We have not had any regrets that we did this. It is scary, but well worth it if you need to/decide to do it. My advice is to have daughter evaluated by a speech pathologist, an ENT, and an Oral Surgeon and compare their advice. One more thing ... this operation can be done at any age .... just, earlier the better in regards to speech .... kids/adults who do it later just need to re-learn a lot of their speech patterns. If the surgery is done at an older age, I think 8 or so according to my ENT, then putting the child ALL the way under isnot needed, they can sit still better. Hope this is helpful --- I felt compelled to write and I know I wrote a lot, but I just remembered how we felt when we were grabbling over what to do, and I feel for you. Good luck - do research - and you'll do the right thing!
