We just went through this with my son - actually, it was almost a year ago and he was little over 2 at the time. I know how you are feeling - we were very worried, especially after we were told how commen this was yet I had never heard of it or seen it before. Don't be worried, everything turned out just fine and it has not come back (even though there is a possibility). I used Dr. Sandra Armstrong in Southlake because my sister in law is a dentist there. The staff was great, they gave my son something to drink (that would knock him out). It took about 45 min for that to kick in so take something to keep her busy in the waiting room. Most dentists/oral surgeons have stuff but after 45min everything is "old news." Once the "juice" began to take effect, they took him back and from what I understand, they numb the area and cut off the mucocele. It is a fairly simple procedure. Beware, the inside of her lip will look worse than it really is because they "burn" it to keep it from bleeding. He slept most of the rest of the day and once he woke up he was fine. After a couple days his lip looked normal and after a week you couldn't tell anything had even really been there. Good Luck!!
