Diagnosis of Dental Fluorosis from dirty teeth.

• In Dental Fluorosis the discolouration will be on the enamel surface
• In the child shown below, the teeth of the upper jaw, the two central incisors have discolouration horizontally aligned on the enamel surface, away from the gums. It is due to Dental Fluorosis and is a permanent feature of the teeth.
• In dirty teeth there will be discolouration of all shades but the discolouration will be along the gums (masuda) and not on the enamel surface.
• The dirty teeth can be cleaned and polished by a Dentist; but not in Fluorosis.
• Whereas in the teeth of the lower jaw, there is discolouration along the gums and is due to dirty teeth, which can be cleaned by a Dentist.
