Duraphat 5000 is a high-fluoride toothpaste specifically designed for the prevention of dental caries (tooth decay) in adults and adolescents aged 16 years and older. With a fluoride concentration of 5000 ppm (parts per million), it is significantly stronger than regular over-the-counter toothpastes, making it an effective choice for individuals at high risk of cavities or those with existing dental issues that require intensive care. Duraphat 5000 works by strengthening tooth enamel, making it more resistant to acid attacks from plaque bacteria and sugars in the mouth. It is typically used once daily, or as directed by a dental professional, and is often prescribed for patients who need extra protection against tooth decay, such as those with dry mouth conditions, wearing orthodontic appliances, or undergoing head and neck radiation therapy which can affect saliva production and, consequently, oral health.
