The accumulation of fluoride in the teeth is called dental fluorosis, a condition that affects their structure and appearance.
Dental fluorosis first appeared at the beginning of the 20th century when a high prevalence of consultations for tooth stains later called “colorado brown stain”.
The formation of temporary teeth occurs during intrauterine life and continues until approximately 3 or 4 years of age.
In the case of permanent teeth, which are formed between the ages of 3 and approximately 8 years, it has been shown that fluorosis is due to the interaction of fluoride with the forming enamel.
Fluorosis is mainly caused by fluoride intake over a long period of time, precisely during the period of tooth formation.
Teeth whitening technique is used to remove stains and make teeth whiter; however, over time it can worsen the appearance of fluorosis.
