The looser your tooth is when you try to pull it out, the less pain you will feel. You can use your tongue and fingers to loosen your tooth with a gentle wiggling motion. Just make sure that you do not pull or push your tooth too hard as you wiggle it or it may hurt. Use a gentle wiggling motion throughout the day to help loosen the tooth and make it ready to come out. You can also eat crunchy foods to help loosen the tooth and help it to come out without any pain. Chew on apples, carrots, celery, or other crunchy foods to help loosen up your tooth a bit more.  You may want to start with something that is not too crunchy to make sure that this does not cause you any pain. Try chewing on a peach or a piece of cheese to start and then move on to something a bit crunchier. Try not to swallow the tooth. If you feel like the tooth has come loose as you are chewing on something, then spit the food into a napkin to check for the tooth. If you accidentally swallow a tooth, then call your doctor or dentist. There is probably no cause to worry if a child swallows a baby tooth, but you may want to ask your dentist just to be sure. Regular brushing and flossing may also help to loosen your tooth and make it easier to pull out. Just try not to brush or floss too hard or it may be painful. Make sure that you brush and floss as usual (twice per day) to help loosen the tooth and keep your other teeth healthy as well.  To floss your teeth, use about 18 inches (46 cm) of floss and wind most of it around the middle finger of one hand and the rest around the middle finger of the other hand. Hold the floss between your thumb and your forefinger. Then, guide the floss between the loose tooth and its neighbor teeth with a back and forth motion. Try to curve the floss around the bottom of the loose tooth as you do so. You can also use an up-and-down motion to rub each side of each tooth.  For a better grip, use a flossing pick, which can be found in supermarkets.
