Sonic vibration, blue LED technology and 4 smart modes, designed for your most important daily care ritual.
Stubborn plaque that manual brushing misses and that leads to tartar over time. Clean mode delivers 38,400 vibrations per minute for clinically superior plaque removal in every 2-minute session.
Discoloration that builds gradually and dulls the smile. White mode works harder on stained areas while the 6 blue LEDs enhance the whitening effect simultaneously.
Brushing that causes discomfort or pain with standard electric brushes. Sensitive mode reduces vibration intensity for a gentle, thorough clean that does not aggravate sensitivity.
Teeth that look clean but lack natural lustre. Polish mode shifts vibration rapidly every 0.1 seconds to simulate a professional polish, particularly effective on the incisor area.
Stopping too early and missing the full 2 minutes dentists recommend. The smart timer and 30-second quadrant alerts guarantee a complete, evenly distributed clean every single time.
Residual bacteria that accumulate on uncovered brush heads. Rinsing and storing upright after every session allows proper drainage and air drying to minimise bacterial growth.
Bristles that degrade over time and clean less effectively. Replacement brush heads are recommended every 3 months to maintain full cleaning performance.
Incorrect angling that leaves areas of the mouth undercleaned. The 45-degree gum angle guidance ensures the bristles reach the gum line for a thorough, professional-level clean.
A simple, dentist-approved ritual designed to clean more deeply, whiten more effectively and protect gum health every single day.

The 30-second timer has completely changed how I brush. I never realised how unevenly I was cleaning before. My teeth feel professionally cleaned every single morning.

I have tried several sonic brushes and this is the only one where the LED technology seems to make a visible difference to the brightness of my teeth over time. Genuinely impressed.

As someone with sensitive gums who always dreaded brushing hard enough, the Sensitive mode has been life-changing. Thorough, comfortable and my gum health has noticeably improved.

The Polish mode on my front teeth has made a visible difference in just a few weeks. My teeth look smoother and brighter without any whitening treatments at all.

Four weeks on a single charge is not a claim I believed until I tested it myself. Genuinely impressive battery life and the memory function means my preferred mode is always waiting for me.

My coffee habit had left visible staining that I was embarrassed about. Using the White mode daily alongside the blue LED, the difference after one month is noticeable enough that friends have commented.

ADVANCED SONIC LED TECHNOLOGY
Choose the brushing experience your teeth need, from maximum power cleaning to gentle sensitive care, polish and whitening.
Professional sonic frequency that removes plaque more thoroughly in 2 minutes than manual brushing does in longer sessions.
Clean, Sensitive, Polish and White cover every oral care need in a single device, for every person in the household.
A single 10-hour charge powers 4 weeks of twice-daily brushing, making this the most battery-efficient sonic toothbrush available.
The smart timer and 30-second quadrant alerts guarantee the dentist-recommended brushing time, every single session.
Everything you need to know before starting your 2-minute daily dental ritual at home.
Clean mode is the default and most powerful setting, recommended as the starting point for most users. If you find sonic vibration overwhelming at first, switch to Sensitive mode and gradually build up to Clean as your teeth and gums adapt over the first few weeks.
A full 10-hour charge powers the toothbrush for approximately 4 weeks of use, based on two 2-minute sessions per day. Turn the brush off before charging, connect the charging base to a power source and place the handle on the base. The indicator turns red during charging and green when fully charged. We recommend keeping the brush on the charger when not in use.
Replace the brush head every 3 months, in line with dental professional guidelines. When bristles are worn, cleaning effectiveness is reduced. Two replacement brush heads are included in the box to get you started.
Yes. The toothbrush is IPX7 waterproof, meaning it is fully protected against water immersion and safe to rinse under running water. Do not submerge the charging base in water and always keep the charging port dry before charging.
Yes, and it is recommended. The blue LED technology works most effectively when combined with a whitening toothpaste or whitening gel. White and Polish modes are specifically designed to enhance whitening results when used alongside compatible products.
