Key Benefits

The ETERNAS Electric Sonic Toothbrush combines 38,400 rpm sonic vibration with blue LED Premier technology and 4 smart brushing modes to deliver a genuinely superior clean, with clinically proven plaque removal, natural whitening and protection for sensitive teeth and gums.

Removes plaque with superior efficiency using 38,400 vibrations per minute in Clean mode, the most powerful setting available.
Whitens teeth naturally using 6 blue LED bulbs that clean and brighten simultaneously, with even better results when used alongside a whitening toothpaste or gel.
Protects sensitive teeth and gums with a dedicated Sensitive mode that reduces vibration intensity without compromising cleaning effectiveness.
Polishes and refines tooth surface with Polish mode, which shifts vibration intensity rapidly every 0.1 seconds to stimulate a professional polishing effect.
Removes surface stains from coffee and tea in White mode, working a little harder where superficial staining accumulates.
Smart 2-minute timer with 4 quadrant alerts every 30 seconds ensures the dentist-recommended brushing time, consistently and automatically.
Memory function remembers your last mode and repeats it on startup, so your preferred setting is always ready when you are.

How It Works

The toothbrush uses sonic vibration and blue LED light across 4 modes in a simple daily routine:

Attach the Head — Insert the brush head into the main body following the direction of the arrow.
Apply Toothpaste — Place a small amount of toothpaste on the brush head and dampen it lightly.
Select Your Mode — Press the arrow button to cycle through Clean, Sensitive, Polish and White until the indicator for your preferred mode illuminates. That mode becomes the default until you change it.
Brush — Place the brush in your mouth at a 45-degree angle to the gums and move slowly and evenly across all surfaces.
Follow the Quadrant Timer — The brush pauses briefly every 30 seconds to prompt you to move to the next area of the mouth, completing a full 2-minute cycle.
Rinse and Store — After brushing, rinse the brush head and handle with clean water. Store upright to allow proper drainage and air drying.

Real Oral Health Results

Before & After

Visibly Cleaner Teeth

Plaque and buildup are removed more thoroughly than manual brushing, with noticeably cleaner-feeling teeth from the very first use.

Before & After

Whiter, Brighter Smile

Surface stains from coffee, tea and food fade gradually with consistent use of White and Polish modes alongside the blue LED technology.

Before & After

Healthier Gums

Sensitive mode and the 45-degree brushing angle reduce gum irritation, with visibly healthier, less inflamed gums over weeks of daily use.

Sonic vibration, blue LED technology and 4 smart modes, designed for your most important daily care ritual.

Plaque Buildup

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.

Surface Staining from Coffee and Tea

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.

Sensitive Teeth and Gums

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.

Dull Enamel and Lack of Shine

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.

Inconsistent Brushing Time

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.

Bacteria on the Brush Head

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.

Worn or Ineffective Brush Heads

Bristles that degrade over time and clean less effectively. Replacement brush heads are recommended every 3 months to maintain full cleaning performance.

Poor Brushing Angle and Technique

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.

Attach and Apply

Fit the brush head onto the handle following the arrow direction. Apply a small amount of toothpaste to the head and dampen lightly before starting.

Select Your Mode

Press the arrow button to choose Clean for maximum power, Sensitive for gentle care, Polish for surface refinement, or White for targeted stain removal.

Brush at 45 Degrees

Position the brush head at a 45-degree angle to the gum line and move slowly and evenly across all tooth surfaces without pressing too hard.

Follow the Smart Timer

The brush pauses every 30 seconds to prompt you to move to the next quadrant. Two minutes later, your complete professional-grade clean is done.

Rinse and Store Upright

Rinse the brush head and handle with clean water. Store vertically to allow moisture to drain fully and the bristles to air dry between uses.

“My Dentist Said My Teeth Have Never Been Cleaner”

I switched to this brush three months ago and my last checkup was genuinely the best feedback I have ever had. The Clean mode is powerful in a way my previous electric brush simply was not.

“I Finally Have a Brush That Does Not Hurt My Sensitive Gums”

The Sensitive mode has been a complete revelation. I can brush properly for the full two minutes without any discomfort, and my gums look so much healthier.

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.

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.

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.
