Well everybody has the right ideal here about pulling a baby tooth that is loose. The old string trickt does work. Tying the string around the tooth and either pulling it fast with your hand or tying it to the door knob and shutting the door fast. Either way it goes, it is not like the pain of a dentist pulling a solid tooth out. It only last a second and it is over.
Here is a good trick that my Aunt taught us to pulling a tooth out that is loose. Make sure the tooth is really loose first. Take a wash cloth and put it over the tooth that is to be pulled out. Then with your fingers over the tooth to be pulled out, "pinch" the tooth and pull it. The wash cloth "grips" the tooth for a good hold and it comes out easy. The old string trick is a good one.
As for going to the dentist to get a baby tooth pulled out, no don't do that, that is if it loose. That is wasted money and time. Now if the baby tooth is still solid and is bad, yes go to the dentist to have it removed.
Most times if the baby tooth is loose, it will come out on it's own, but don't leave it in there for a long time waiting for it to come out on it's own. Some times they need help. As the adult tooth comes in, if the baby tooth is still there, the adult tooth might not be able to "push" the baby tooth out for some reason or other and will grow over the top of the baby tooth. I know as this happened to me.
