Tooth decay, also known as dental decay or dental caries, is a major health concern. It is caused by acids made by bacteria in dental plaque. Each time you have sugary food and drink, the bacteria produces acid that attacks teeth, eventually leading tooth decay.
Fluoride works by restoring minerals to tooth surfaces where bacteria may have eroded the enamel. It can also inhibit the growth of harmful oral bacteria and further prevent cavities.
There are three basic ﬂuoride delivery methods for caries prevention; community based (ﬂuoridated water), self- administered (toothpastes and mouth-rinses) and professionally administered (ﬂuoride gels, varnishes).
Fluoride Mouth rinses:
The application time for professionally applied gels is 4 minutes and the frequency of application is up to 4 times a year, depending on caries risk. Self-applied ﬂuoride gel is applied more frequently, either daily or weekly, and is recommended for high risk individuals, such as those undergoing ﬁxed appliance orthodontic treatment or patients with hypo salivary function
