What is Colgate Duraphat?
Colgate Duraphat 5000ppm is a high-strength fluoride toothpaste prescribed for the prevention of dental caries (tooth decay) in adults and adolescents aged 16 years and over who are at increased risk. It contains 5000 parts per million (ppm) of fluoride - over three times more than regular toothpaste - to strengthen enamel, prevent cavities, and stop early decay in its tracks.
How does it work?
Fluoride helps remineralise weakened enamel and makes teeth more resistant to acid attacks from bacteria and sugary foods. Duraphat's high fluoride content is especially effective for people who have a history of dental decay, wear braces or dentures, suffer from dry mouth, or have exposed root surfaces. It helps to reduce bacterial acid production and promotes repair of early tooth damage before cavities form.
How to use Colgate Duraphat
- Brush your teeth three times daily, ideally after meals
- Use a 2 cm ribbon on your toothbrush and brush for three minutes
- Spit out after brushing - do not rinse, so the fluoride stays on your teeth
- Do not swallow the toothpaste
- Not recommended for use in children under 16 years
Who is it for?
Colgate Duraphat is designed for people at high risk of dental decay, including:
- Frequent cavities or history of decay
- Orthodontic appliances (braces, retainers)
- Dry mouth (xerostomia) or reduced saliva flow
