How to painlessly pull out a loose baby tooth
Evaluate how ready the tooth is to come out.
Baby teeth loosen gradually, and often take two or more weeks to loosen enough to be removed from your child's mouth. Although children are often excited to lose their baby teeth, it can be painful if the tooth is not sufficiently loose.

Options are:
[A]. Inspect your child's tooth, and see if it's ready to come out. If the tooth is only connected by a small flap of gum tissue, encourage your child to loosen it further until the tooth falls out.
[B]. Ask your child's pediatrician what it is that is preventing a tooth from coming out. Understand that babies need a regular dental check-up.
[C]. If the tooth is already detached or completely healed, your child may bite and attempt to pull their tooth out. The tooth is not easily removed in children without proper nutrition.
[D]. If the tooth is around the age of 2 in (5.4 in) or larger, and the tooth is long and tartar free, it is likely to come out early. Look for clear menstrual streaks.
[A].
