Dental Fluorosis in Kanpur: Causes, Grades & Treatment

Dental fluorosis is a permanent change in tooth enamel caused by excess fluoride exposure while permanent teeth were forming. In Kanpur, groundwater from borewells and handpumps may be an important source.

Causes

Common contributors include high-fluoride drinking water, swallowed fluoridated toothpaste, fluoride supplements, and cumulative dietary sources. Children are most vulnerable during enamel development, particularly between birth and eight years of age.

Signs and grades

Mild fluorosis appears as white streaks, flecks, or cloudy patches. Moderate cases may include brown staining and surface wear, while severe fluorosis can cause noticeable pitting. Symptoms often affect matching teeth on both sides of the mouth.

Diagnosis

A dentist can distinguish fluorosis from plaque, tartar, enamel hypoplasia, and early decay by examining the tooth surface, pattern, symmetry, and degree of enamel damage. Dean’s Fluorosis Index or the Thylstrup–Fejerskov index may be used to grade its severity.

Treatment

Fluorosis cannot be cured because the alteration is within the enamel. Depending on severity, treatment may include enamel microabrasion, resin infiltration, tooth-coloured composite bonding, or porcelain veneers. Teeth-whitening alone generally does not remove white fluorosis opacities.

Prevention

Test the household drinking water, use the correct amount of fluoride toothpaste, supervise young children while brushing, and avoid fluoride supplements when the water already contains excessive fluoride. Early assessment helps determine whether monitoring or cosmetic treatment is appropriate.
