While sitting, scoot your butt to the front of your chair. Then lean back so that your upper back rests lightly on the seat back. Contract abs and lift your right knee up, then place your foot back down on the floor. Repeat with your left leg, doing 10 reps on each side. Then, sit up straight on the front edge of your chair, engage abs and lean back again to lean upper back against the chair back. Sit up straight again, using your abs.
A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent bridge is placed. A Flipper can be attached via either a wire or a plastic piece that fits in the roof of your mouth. Flippers are meant to be a temporary solution while awaiting the permanent bridge.
Primary teeth become loose and fall out because the secondary teeth, also known as permanent teeth, begin to emerge and need room to grow. At the age of 12 or 13, most kids have lost all of their baby teeth and will have a full set of permanent teeth. A pediatric dentist will assist you in the care of your teeth from when you are a baby until you are a teenager.
