The reservoir's capacity, measured in millilitres (ml), determines how long you can floss before needing a refill. A typical session lasts between 60 and 90 seconds.
Water pressure is measured in bars or PSI. Higher pressure can be more effective for plaque removal but may be uncomfortable for those with sensitive gums. Models with multiple settings offer the flexibility to start at a low pressure and adjust it to your comfort level.

1. Is a water flosser a replacement for traditional floss? A water flosser and traditional floss work differently. Floss physically scrapes plaque from the tooth surface. A water flosser uses a pulsating stream of water to flush away food debris and plaque, especially in hard-to-reach areas and below the gumline. For people with braces, implants, or sensitive gums, a water flosser can be a more effective and comfortable alternative. Consult your dentist or dental hygienist for advice tailored to your specific dental needs.
2. Can I use mouthwash in a water flosser? With many models, like the Waterpik WF-112, it is possible to add a small amount of mouthwash to the water for a fresher sensation. However, it is crucial to always check the manufacturer's instructions. Certain chemicals in mouthwash can damage the device's materials over time. Always rinse the unit thoroughly with plain water after using it with mouthwash.
3. How often should I use a water flosser? For optimal oral hygiene, it is generally recommended to perform interdental cleaning at least once a day. Using a water flosser can become a regular part of this routine, for instance, in the evening before brushing your teeth.
