-if this is a real photo and it may really be from someone's mouth b/c i meet people all the time that have gross teeth with like tartar and yellow to brown coloration and covered in film- god, people brush your f**king teeth...no offense but you have tartar and that takes a long time to build- you really need to brush your teeth 2X a day, floss 2X, oil pull 20 mins, brush all portions of mouth, brush tongue, floss the last mortors, and goggle with hydrogen peroxide...
