Water flossers are increasingly popular because they are easier than string floss. But can they replace floss entirely, and how do you use one without hurting the gums?
- A water flosser pushes out debris with a jet of water, while floss rubs directly to remove sticky plaque.
- A water flosser is a useful supporting tool but not always a complete replacement for floss.
- Start at low pressure and avoid aiming a strong jet at sore, swollen gums.
- Constant food trapping or persistent bleeding gums should be examined.
Both water flossers and dental floss aim to clean between the teeth, where a toothbrush has difficulty reaching. Each works in a different way, and which one suits you depends on how tight your teeth are, the condition of your gums and what you find easy to keep up every day.
How do the two tools work differently?
- A water flosser uses a jet of water to push out food debris and clean hard-to-reach areas, handy for people with bridges, dentures or difficulty handling floss.
- Dental floss rubs directly against the tooth wall, so it removes the thin, sticky plaque a water jet may not sweep away.
So many dentists see a water flosser as a very useful supporting tool, but not always a complete replacement for floss. If the spaces between your teeth are tight, floss is still often advised.
How do you use a water flosser properly?
- Start at low pressure and increase gradually once you are used to it.
- Lean over the sink and keep your lips slightly closed so the water runs out.
- Guide the tip along the gum line and between each pair of teeth.
- Do not aim a strong jet straight at gums that are sore and swollen.
- Change the water and clean the tank and tip regularly.
It does not replace the toothbrush. You still need to brush properly; see how to brush properly.
When should you ask the dentist?
- Food keeps getting trapped between the teeth. See why food keeps getting stuck between teeth.
- Your gums bleed a lot despite careful cleaning; see bleeding gums: what is the cause.
- You wear a bridge or denture or have an implant and do not know the right way to clean.
