Demand characteristics: People wearing braces face challenges in cleaning their teeth, especially around the braces and brackets, where food residues and plaque tend to accumulate. Traditional dental floss is difficult to use and can easily damage the gums. Water flossers offer a more convenient and efficient cleaning method. Main advantage: The water flow can effectively clean the areas around the dental braces and those that are difficult to reach, preventing plaque and gingivitis.

Demand characteristics: Cleaning around dental implants or false teeth is often more complicated than cleaning natural teeth. Regular brushing may not reach all areas, especially between the false teeth and the gums. Main advantage: Water flossers can clean the gaps of dental implants or dentures more gently, reducing the risk of infection and inflammation.

Demand characteristics: Some people are short of time and thus reluctant to spend too much time on oral hygiene. Water flossers clean teeth faster than traditional manual flosses, and are particularly suitable for those who need efficient cleaning. Main advantages: Easy to use and highly efficient, suitable for a fast-paced lifestyle.

Demand characteristics: Elderly people or those with limited mobility may have difficulty using traditional dental floss, especially for those with limited hand strength. Water flossers are relatively easy to operate, reducing the physical challenges involved in using dental floss. Main advantages: It is more convenient to use, the operation is simple, and no excessive manual operations are required.

Demand characteristics: For younger children, especially those undergoing orthodontic treatment, using traditional dental floss may be difficult and uncomfortable. Water flossers are more acceptable to children and can stimulate their interest in oral hygiene. Main advantages: Gentle, effective and easy to operate, it is more likely to help children develop good oral hygiene habits.
