Introduction Dental caries (tooth decay) is a pathological process resulting in localised destruction of tooth tissue. Dental plaque (a complex biofilm of mixed bacteria and their by-products) is a prerequisite for dental caries development. Frequent exposure to dietary sugar and carbohydrates leads to an increase in the population of cariogenic bacteria in the biofilm. Cariogenic bacteria produce organic acids, which lower the pH of the biofilm, resulting in enamel demineralisation (loss of carbonated hydroxyapatite). NOTE:  Dental caries can often progress without noticeable signs of deep or large cavities. To prevent further deterioration, it is advisable to consult a dentist as soon as you experience sensitivity to hot or cold temperatures, rather than waiting for more severe pain. Fluoride-containing Toothpaste Use of fluorides is the primary means of preventing dental caries across all age groups . Fluoride promotes enamel remineralisation through the formation of fluoride-c...

Introduction Tooth brushing is the most commonly recommended oral hygiene behaviour . It is the primary mechanical means for removing dental plaque, thereby assisting in the prevention of oral diseases including gingivitis and dental caries. Duration and Frequency It is widely recommended that patients brush their teeth with a fluoride toothpaste for a duration of 2 minutes twice daily. Brushing for a period of 2 minutes achieves clinically significant plaque removal , removing more plaque than when teeth are brushed for only 1 minute. Patients should also be counselled to divide each brushing session into 30 second segments for each quadrant of the mouth. NOTE: Fluoride is anticariogenic, meaning it prevents tooth decay. Toothbrushing Technique Multiple toothbrushing techniques have been recommended by dental associations, toothpaste and toothbrush companies and in dental texts (e.g. Bass technique, Fones technique, Scrub technique), but studies have not reliably demonstrated one ...
