Smile and the world smiles back unless there are teeth missing.  Missing front teeth can be funny but more often they cause pain.  The missing front teeth are common in drug abusers and the poor.  Though front missing teeth are embarrassing the teeth in the back of your mouth are the ones that are needed the most and when you cant afford dental care these are the ones that most people have pulled or are in the worst shape, cracked and damaged. The back teeth are also the most likely o have old filling in your teeth having lead in the filling which they are now having to replace because they say are not good for your health.  What have we done to are bodies in the name of science and progress.  Createurs De Luxe has that smile.
