Ingestion of food or beverages following a fluoride application can potentially reduce the efficacy of the treatment. Fluoride needs a certain amount of time in contact with the tooth enamel to maximize its protective effects. Consuming food or drinks too soon after disrupts this process, potentially washing away the fluoride before it has fully integrated into the enamel structure.
The primary benefit of fluoride treatment lies in strengthening tooth enamel and increasing its resistance to acid attacks caused by bacteria. This preventative measure significantly reduces the risk of dental caries (cavities). Historically, fluoride application has proven instrumental in improving overall oral health and reducing the prevalence of tooth decay across various populations. Allowing the fluoride to properly absorb ensures optimal protection against demineralization.
