Why should I choose Brusheva over other sonic toothbrush brands?
Brusheva is custom-designed by an international dental expert team and recommended by 98% of Hong Kong dental professionals surveyed.
The team spans orthodontics, periodontics and more, and understands the limits of most electric toothbrushes. Brusheva features breakthrough ultra-soft bristles, carefully sized heads and approx. 30,000–32,000 sonic vibrations per minute for a deep yet gentle clean. A 2023 Hong Kong healthcare survey found 98% of dental professionals would recommend Brusheva.
What is the difference between sonic and rotary electric toothbrushes?
Sonic brushes use high-frequency vibrations for fluid cleaning between teeth; rotary brushes spin the head to scrub tooth surfaces.
Sonic brushes typically exceed 31,000 strokes per minute, using fluid dynamics to reach between teeth more broadly and gently than rotary-only cleaning. Brusheva delivers approx. 30,000–32,000 sonic vibrations per minute with micro-bubble action — especially helpful for sensitive gums and braces.
How do I use Brusheva correctly for the best oral hygiene?
Brush at least twice a day for two minutes, holding the bristles lightly against your teeth and letting the sonic action work.
See the instructional video on the product page for a step-by-step demo from our dental experts. Use the built-in 2-minute timer with 30-second quadrant prompts for a full 360° clean.
Are there case studies or test results supporting Brusheva?
Yes — Brusheva undergoes international safety testing and Hong Kong market research.
After 7 days of use, 96.8% of dental professionals agreed Brusheva reduced gum bleeding; 96.9% agreed it improved breath; 100% agreed it delivered a professional deep clean; 98% agreed the soft bristles were safe for sensitive gums; 98% strongly recommended it as trustworthy.
What special design features does Brusheva have?
Ergonomic handle, four dedicated heads, balanced sonic frequency, a 2-minute smart timer and IPX7 waterproofing.
Rounded ultra-soft bristles massage without harming gums; head and handle dimensions reach wisdom teeth and rear molars; a stable magnetic drive reduces handle vibration; five modes each offer three intensity levels; four head types cover whitening, tongue care, all-round and ultra-soft needs.
How often should I replace the brush head?
Replace the head every three months.
Worn, splayed or discoloured bristles clean less effectively and harbour more bacteria. Brusheva offers whitening, tongue-care, all-round and ultra-soft replacement heads (3-pack HK$149).
Which head should I use with braces?
Use the ultra-soft head with sensitive or massage mode.
Plaque builds up around brackets easily. Brusheva's sonic action reaches behind wires while the ultra-soft bristles clean gently without damaging braces or gums.
Can I use Brusheva if I have gum disease?
Yes, but consult your dentist first and use sensitive mode.
Ultra-soft bristles are designed for gum disease, loose teeth and sensitive gums. Sonic vibration helps remove plaque, but gum disease requires professional treatment and regular check-ups.
How long does the Brusheva battery last?
Up to 12 weeks (about two to three months) on a single charge.
With twice-daily two-minute brushing in standard mode, you rarely need to recharge. Charge overnight before first use for best performance.
Can I use Brusheva in the shower?
Yes — the whole brush meets the IPX7 waterproof standard.
Use it safely in the shower and rinse the handle under running water, but do not soak it for long periods and keep the charging port dry when charging.
Is Brusheva suitable for children?
We recommend supervised use for children aged 8 and above.
Sensitive mode and the ultra-soft head run gently. Children should use a lower-intensity mode with adult guidance on technique and brushing time.
Is there a warranty?
Yes — a one-year limited warranty and customer support are included.
It covers manufacturing and material defects under normal use, not wear items like brush heads. Email hello@brusheva.hk with your order number or WhatsApp 98568963 to reach our team. See the warranty page for details.
Is the Brusheva sonic toothbrush safe?
Yes — the brush and battery are tested by international agencies with safety certificates issued.
We run rigorous safety tests so Brusheva meets the highest standards for everyday use.
How long is shipping in Hong Kong?
Hong Kong orders arrive in 2–4 business days with free shipping.
We dispatch soon after your order is confirmed. We also ship to China, Macau, Taiwan and the UK — shipping is shown at checkout.
How do the five cleaning modes differ?
Five modes — clean, white, massage, sensitive and care — vary in intensity and purpose.
Clean is for everyday use; white targets surface stains; massage stimulates gums; sensitive is gentlest; care balances comfort and cleaning. Each mode has three intensity levels.
Is it suitable for sensitive gums?
Yes — use sensitive mode with the ultra-soft head.
Sensitive mode runs at a gentler vibration and, with ultra-soft bristles, removes plaque effectively while protecting sensitive gums and reducing bleeding risk.
