Hey there! do any of you aware of using laughing gas for children? Our dentist said that he will be using that for the next appointment of my son (during the filling procedure), so that my son will be relaxed. I heard that it acts as a sedative and I am scared! But the doctor said some facts about it and showed me a blog regarding that ( www.discoverydental.com/blog/laughing-gas/laughing-gas-safe-children/ ). It sounds safe, but I don't know why I am getting tensed. Do any of you can explain me some more details on this? His next appointment is on 15th of this month. Any suggestions would be highly appreciated.
