Explanation lettering: B = shown as A · C = shown as B · A = shown as C · E = shown as D · D = shown as E
The correct answer is A: 1,350–1,500 ppm fluoride. Current UK Delivering Better Oral Health guidance recommends this concentration for family or standard toothpaste, including routine adult use. Lower-strength toothpaste containing at least 1,000 ppm may be used for very young children when swallowing is a concern, so B is not the routine adult recommendation. Concentrations around 2,800 ppm and 5,000 ppm, represented by D and E, are high-fluoride prescription preparations considered for patients with increased caries susceptibility rather than routine adult self-care. C is not a standard recommended UK toothpaste concentration band. Adults should normally brush at least twice daily, including last thing at night or before bed, spit out the excess toothpaste and avoid rinsing immediately afterwards.
