CONSENSUS STATEMENT POST-BRUSHING
Consensus statement on post-brushing rinsing behaviour, from the British Dental Journal 2012
Rinsing with water after brushing with fluoride toothpaste can reduce the benefit of fluoride toothpaste.
There is a theoretical benefit in keeping the intra-oral levels of fluoride elevated by replacing a post-brushing water rinse with a fluoride rinse.
Non-fluoride rinses should preferably be used before brushing or at a different time to brushing with fluoride toothpaste.
Mouth rinses containing fluoride can be used after brushing with fluoride toothpaste.
For the general population, including children aged 12 years and above:
- Brush twice daily with a fluoride toothpaste; do not rinse excessively with water; use one of the three recognised post-brushing approaches to enhance fluoride retention
For children at high risk of caries:
- Rinsing should be supervised until an age where parents/carers are confident that children will not drink the rinse
- Mouth rinses should not be used before the age of 6 years. (However, studies in Japan have indicated that 4–5-year-olds can rinse under supervision. In addition, children with newly erupting teeth may gain a long-term benefit from using mouth rinses)
- Use 10 ml twice daily of mouth rinse up to 100 ppm fluoride, or 10 ml once daily of mouth rinse up to 226 ppm fluoride
- Avoid the risk of approaching the lethal dose of fluoride by using an appropriate bottle size
The panel also encouraged future research with a range of mouth rinse products to explore the effects of the interplay between the frequency of use of mouth rinse agents and fluoride concentration.
