Areas of use – who is the MD-310 suitable for?
The Promed oral irrigator MD-310 supports daily oral care and complements brushing. Particularly recommended for:
- Daily interdental cleaning: an effective addition to your toothbrush for the spaces between the teeth and the gum line.
- Braces, bridges and crowns: the orthodontic nozzle reaches hard-to-access spots around dental work.
- Sensitive gums: the Soft mode allows a particularly gentle application.
- Fresh breath: the tongue-cleaner attachment removes tongue coating.
Using it is this easy
- Step 1 – Charge & prepare: before first use, charge the battery for approx. 3–4 hours via USB-C and rinse the tank and nozzles with water.
- Step 2 – Choose a nozzle & fill the tank: attach the desired nozzle, fill the tank with lukewarm water (max. 40 °C) and close the lid.
- Step 3 – Select a mode & use: lean over the sink, place the nozzle in your mouth, only then switch on and choose between Soft, Normal, Pulse, DIY and Spot. Guide the jet along the gum line and between the teeth.
- Step 4 – After use: switch the device off, empty the tank and let the parts air-dry. Replace nozzles every 3–6 months and do not share them with other people.

Frequently asked questions (FAQ)
Which mode is suitable for beginners?
For first use and for sensitive gums, the Soft mode (55–110 PSI) is recommended. For daily cleaning, the Normal mode is then suitable.
What does the DIY mode do?
In DIY mode the pressure gradually increases within a 12-second cycle from weak (30 PSI) to strong (140 PSI) – you can stop individually as soon as the intensity feels right.
Can the oral irrigator be used in the shower or under running water?
Yes – the Promed MD-310 is IPX7 waterproof and can easily be rinsed under running water.
My gums bleed the first time I use it – is that normal?
Light bleeding in the first few days is normal and usually subsides within 1–2 weeks. If the bleeding persists, please speak to your dentist.
How often should I replace the nozzles?
Replace the nozzles every 3–6 months or sooner if wear becomes visible. Matching replacement nozzles for the black MD-310 can be found under article numbers 470009–470014.
How long does the battery last?
With once-daily use, one battery charge lasts up to 35 days. The Li-ion battery is charged via USB-C; a full charge takes approx. 3–4 hours.
Does the oral irrigator replace brushing?
No. The Promed MD-310 is a useful addition to daily oral care, but not a substitute for a toothbrush or a visit to the dentist.
Is the MD-310 also available in another colour?
Yes – besides black (art. 470002), the Promed MD-310 is also available in white (art. 470001). The technology and features are identical for both versions; only the matching replacement nozzles differ in colour.
