Anyone know what is a white lesion in teeth, and natural sources to whiten teeth?

See Dentist: White spots =less calcium areas – have your dentist check these. Any whitening system that you can commercially purchase should only be used after the dentist has gotten the stains out of the enamel structure of the tooth, and taken care of any cavities that exist. Otherwise you will be trying to whiten over a deep stain = failure or you will be trying to whiten a cavity = can kill the nerve.

White lesion: If the white spot is hard and opaque it could be a hyperminerized spot, it could be from antibiotic use as a child. If the lesion is chalky feeling and rough it is a cavity that is just beginning. These occur around brackets, between teeth, and at the gum line. You can achieve some whitening using a mixture of baking soda and dilute hydrogen peroxide. Long term use of this can be harmful too.

Decalcification.: A white lesion on teeth can either be a spot that the calcium pattern in the enamel is different from the rest of the tooth (which is harmless) or the first step in cavity formation called "decalcification" which, obviously, is not harmless. Cavities begin with a loss of calcium in the enamel or dentin of the tooth and at that time will appear chalky white. Natural whitening source is a myth.

Enamel defects: White lesions could be hypocalcification or decalcification and a result of disruption of tooth development from fever, infection, excess Fluoride or.....Demineralization from plaque buildup. There is no real way to whiten teeth naturally. Speak to a dentist regarding how best to remove those white spots and about whitening methods that really work.
