Choosing a new pack of electric toothbrush heads seems simple, until you discover that not every brush head fits every handle. Oral-B, Oral-B iO and Philips Sonicare use different connections. The bristle firmness, shape and pack size also affect how comfortable and cost-effective your purchase will be.
Seeing “Oral-B” or “Sonicare” on the packaging isn’t enough. For example, a standard Oral-B brush head won’t necessarily fit an Oral-B iO handle. The Oral-B iO Ultimate Clean range is specifically designed for iO handles. Conversely, many standard Oral-B brush heads aren’t suitable for iO or Pulsonic models.
Most models within the Philips Sonicare system are widely compatible, but always check the model number. Look out for codes such as HX9094/88, HX9044/87, HX6014/87 or HX6016/87.
A pack of 4, 6 or 8 may look like good value, but only if the brush heads suit your handle and how you’ll use them. Most of the selected products recommend replacing the heads after three months, or sooner if the bristles are bent, worn or coming loose.
A pack of 6 could last one person around a year and a half. With several people in the household, a 6-pack of brush heads will be used up sooner. An 8-pack of brush heads can be practical for families, as long as all the heads are designed for the same type of handle.
Brands sometimes quote percentages for plaque removal, gum care or stain removal. These figures come from the brand’s product information and aren’t a universal guarantee for every user. For example, Philips mentions claims about plaque and stain removal for certain Sonicare models in its own research or product information. Use this information to compare products, rather than as a medical promise.
First, check your handle type:
An original brush head will usually have a clear brand name, model number and compatibility information. If you’re buying compatible replacement heads, pay extra attention to the connection, brush head size and information about materials and safety.
Adult brush heads include round Oral-B heads and oval Philips Sonicare heads. The shape affects how you move the brush along your teeth, but it doesn’t determine on its own which head is right for you.
If you’re looking for brush heads for sensitive teeth, consider soft or extra-soft bristles. According to the product information, the Oral-B iO Gentle Care has soft bristles and a gentle outer ring. Philips Sonicare A3 features soft bristles and flexible rubber sides. If you experience persistent irritation, pain or bleeding, stop using the brush head and consult a dentist.
Some electric toothbrush heads have fading bristles to remind you when it’s time for a replacement. On various Oral-B models, the indicator bristles change from green to yellow or from blue to white. Philips Sonicare models may also have fading replacement bristles.
Rinse the brush head after use, leave it to dry upright and don’t share it with others. Don’t use a brush head with damaged or badly bent bristles. The recommended three-month replacement interval is a guideline; heavy use or visible wear may mean you need to replace it sooner.

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and current European safety regulations.
Many manufacturers recommend replacing it every three months. Replace it sooner if the bristles splay, bend or come loose. A replacement indicator can help, but check the brush head yourself too.
No. Standard Oral-B brush heads aren’t designed for Oral-B iO, Pulsonic or Philips Sonicare. Always check your handle model and the compatibility information. iO models in particular need a specific iO brush head.
For children, choose a small brush head with a clear age recommendation, such as Oral-B Kids for children aged 3 and over, or Philips Sonicare For Kids for the stated age group. Supervise children, don’t let them bite the brush head and keep loose brush heads out of reach of young children.
