How old is your child? they tend to clip babies, my 3 year old had surgery in August and did great with it and it only took about 5 minutes he was put under because of his age and it was done w/ a laser there was no bleeding and no pain the thing that bothered him the most was having the tape over the iv taken out (they put the iv in after he was sleeping) Depending on your child's age and how cooperative he/she is they don't need to go under to have it done. We had our son's done because of speech problems and he now doesn't stop talking :)
Edited:Michelle, my son's tongue was very tight. It looked heart shaped when he would try to stick it out it would not go beyond his teeth, he could not lift his tongue, it was interfering with eating he was getting food caught on the roof of his mouth. How are her teeth? It can interfere with the ability to clear food off of molars and lead to cavities it can also cause a gap between the two bottom front teeth which my son has hopefully having the surgery will help with gap when he starts losing teeth and getting adult ones.
