Only if it's a baby tooth and loose, then it won't hurt very much. But if it's not loose and an adult tooth, it will most likely hurt. I had to get two adult teeth and two non loose baby teeth out for my braces and I was pretty miserable later when the laughing gas wore off. I was bleeding for more than 4 hours and I had too much gauze in my mouth that I was gagging! And it was really hard to eat.
