I took my little girl to Dr Lin she is 5 years old. I hear screaming for around 10 minutes as I sat in the lobby waiting for my daughter. I could not go back to the room due to my pregnancy and that fact the nitrous oxide gas was being used. Nitrous help calm nerves. I realized after the 10 min. this was my daughter screaming like this, so I ran back to the room and opened the door n Dr Lin had my daughters head between her knees while an assistant was holding my daughters hands down. I asked why she is in so much pain n she told me my daughter was just nervous, I asked to to stop the root canal, because something was wrong. I had never heard my daughter scream so loudly before so I knew the degree of pain she was in. I removed her from the dentist chair and took her out the dental office. When we got home she was shaking bad from her nerves feeling the whole procedure, of 15 to 20 minutes...not one time did she stop to ask my daughter if she was OK during her screaming and she was given only one anesthetic shot that did not work for my daughter at all, so her primary Dr said usually when the 1st one doesn't work they can offer a second one in hopes to actually numb the area, come to find out my daughter felt the whole procedure of the drill n all. she shook for hours after because of her nerve endings and the pain receptors in her mouth, she was never offered any other form of pain meds only 1 shot which did not numb her at all n even with a child screaming like my girl was she never gave her any other relief but to hold her down and continue drilling...I want everyone to be careful when letting your child go back there and ask for numbing meds like gas...that works like a charm. Shots do not always take effect the first time...My daughter is severely traumatized and never wants to see a dentist ever again, ...n as a mom I feel horrible like I wasn't there to protect her from being hurt n she couldn't speak up to say I'm hurting because she was held down and never given the chance...so please be aware n careful wish she was offered another shot instead of continuing to drill her root with no pain meds...how horrible this must feel...as an adult I know this pain is horrible n my daughter is very tough as she can handle her immunization shots with no crying...and her original dentist she had 2 visits and 4 cavity filling and never cryed once...over pain..or his drilling of her fillings...IF YOU WALK INTO A ROOM AS YOUR CHILD IS SCREAMING BlOOdY MURDER...YOU MIGHT WANT TO WONDER IF SHES NUMBED AT ALL..MORE THAN LIKELY IT IS NOT BECAUSE HE OR SHE IS NERVOUS...IT PROBABLY BECAUSE THEY R IN A WHOLE LOTTA PAIN...2010 November
