Fluoride is commonly used in dental practices as a preventative measure to strengthen tooth enamel, reduce the risk of tooth decay and promote overall oral health. Fluoride is applied in various forms during regular check-ups or as part of specific treatments. 

The common ways in which fluoride is used in dental practices:

• Fluoride varnish: is a concentrated fluoride gel that is applied to the teeth and provides a high concentration of fluoride
  
• Fluoride gels: have a higher concentration of fluoride than toothpaste, sometimes used in dental offices
• Fluoride mouthwash
• Fluoridation with chewing gum
• Fluoride supplements: especially for people with a higher risk of tooth decay, dentists may recommend fluoride supplements, which are in the form of tablets, drops or lozenges.
• Fluoride recommendations and education: includes guidance on the use of fluoride toothpaste and mouthwash
• Assessment of fluoride levels: to assess whether additional fluoride treatments or supplements are needed

Fluoride application in dental practices is a preventive measure to support oral health and prevent dental caries. It is particularly beneficial for children, people at high caries risk and those living in areas with lower levels of fluoride in the water supply.

It is important to follow dentists' recommendations regarding fluoride use, as excessive fluoride intake can lead to fluorosis, an aesthetic problem that affects the enamel of the teeth. Regular dental examinations provide dentists with the opportunity to assess individual needs and provide appropriate fluoride interventions.
