How Often to Replace Brush Heads? Choosing Among Brusheva's Four Types

How often should you replace a brush head?

The general advice is to replace your brush head every 3 months, and that's exactly what Brusheva recommends for all of its replacement heads. Over time the bristles soften, splay outward and lose their springiness, so cleaning power naturally drops — don't wait until the bristles are completely flattened before swapping.

Besides counting the months, watch for real wear signs: bristles fanning out noticeably, the colour-indicator bristles fading, the head feeling less firm when you brush, or having recently been unwell (for example, a cold) — all good moments to change. If you tend to brush hard, the bristles may deform sooner than 3 months, so replace early in that case. Pairing this with Brusheva's 2-minute smart timer (with 30-second pulses) and brushing with gentle, even pressure can actually extend bristle life.

Which Brusheva head suits which kind of person?

Brusheva offers 4 dedicated brush heads: whitening, tongue-care, all-round and ultra-soft, each targeting a different need. In short: pick whitening to brighten your teeth; tongue-care to tackle breath and tongue coating; all-round for everyday all-over cleaning; and ultra-soft if your gums are sensitive or you're just starting out with an electric toothbrush.

Whitening head

Ideal for users targeting surface stains who want a brighter smile. Used with Brusheva's approx. 30,000–32,000 sonic vibrations per minute and the white whitening mode, it cleans day to day while focusing extra attention on brightening the tooth surface.

Tongue-care head

Breath is linked to tongue coating, and this head is designed specifically to clean the tongue surface — perfect for anyone particularly mindful of fresh breath. Add a tongue-cleaning step at the end of brushing to round out your whole oral-care routine.

All-round head

Best suited to everyday use for most people, balancing cleaning and comfort. If you're unsure which to pick, all-round is the safest starting choice and works for daily use with the clean cleaning mode.

Ultra-soft head

With especially gentle bristles, this suits people with sensitive gums, those who find brushing uncomfortable, or anyone just switching from a manual toothbrush to an electric one. Paired with the sensitive mode or the gum-care (Gingiva) mode, it brushes more gently.

What should you watch for when replacing or choosing a head?

The key point: the head must fit your Brusheva handle, and you should pair it with a suitable cleaning mode as needed. All Brusheva replacement heads are designed specifically for its own sonic toothbrush, so just pick the right style when you buy.

All four heads (3-pack) are now HK$149 (was HK$238) — a 3-pack lasts one person about three-quarters of a year, or it can be shared across the family. You can also mix and match for different needs, for example using the all-round head day to day and switching to the whitening head when you want to brighten.
