Best Replacement Toothbrush Heads of 2026

Six heads is eighteen months of brushing if you follow the three-month rule, and that arithmetic is most of the case for this pack. Each head carries a BrushSync chip in the collar, so the handle's own replacement light keeps doing the remembering for you. A year and a half from one order, with the reminder handled, is why this is our pick for Sonicare click-on handles.

The C2 is the plaque-control head: a power tip at the end of the bristle field for the gaps at the back, with the usual Sonicare motion underneath. It's a general clean rather than a whitening or gum-specific one, which is what most people replacing a worn head actually need. The collar is the standard click-on fitting, so it seats on any Sonicare click-on handle.

Two things to know before you commit. The bristles are medium, not soft, and firmer than the gentle language on the box suggests. And a head can shed a tuft before its three months are up; with six in the pack you have a spare to swap in, which is part of the point of buying a supply rather than a pair.

Whitening is the whole reason this head exists. A small polishing pad sits at the center of a diamond-shaped bristle field, and the shape is designed to hold more of that pad against the tooth as you brush. Philips claims a week of use shifts noticeably more surface stain than a standard head. We can't measure a stain percentage, but this is the only head in the set designed specifically for it, and that counts if coffee and tea show on your teeth.

Three heads is nine months, and the blue indicator bristles pale as the head wears, so the change is written on the head rather than left to your memory. Cost is the sticking point: per head this is the priciest Sonicare option here, and the whitening pad does nothing at the gumline that the C2 doesn't already do. If your teeth are already the shade you want, put the difference toward a bigger pack of the cheaper head.

Check the handle before ordering. These are the refills for Oral-B's battery-powered brushes — Complete, 3D White and Pro-Health battery models — and not the rechargeable handle sitting on the charger, which takes a different head entirely. Get that right and the rest is straightforward: soft bristles, a round rotating head, and a pop-off design that lets you rinse toothpaste residue out of the collar instead of watching it set.

Two heads in a pack makes this the priciest per head in the set, which sounds odd for a budget brush until you price the alternative — a whole new brush every time the bristles splay. What we found is that it does the simple things well: soft enough for twice-daily use, a firm seat on the handle, and a clean that stands up next to the rechargeable heads here. If you're keeping a battery brush going, this is the refill that keeps it worth keeping.

Twenty heads works out to about five years of brushing at one head every three months, which sounds absurd until you have three Oral-B handles in the house and a teenager who never mentions that the bristles have splayed. A box that size turns a recurring purchase into something you do once and then forget about.

They're third-party heads made to fit Oral-B Braun rechargeable handles, and they snap on the way the branded ones do. The bristles are angled and densely packed, and seating is where compatible heads usually fall down — a head that sits proud on the stem makes the whole brush feel buzzy and loose. These seat cleanly, which is the first thing to check when you buy compatible.

Feel is where they part company with the genuine article. Soft is the word on the box, but they run firmer than that, and the split is real: bracing for some, harsh along the gumline for others. They also wear faster, so you may be swapping at two months rather than three. For a house full of Oral-B handles and nobody with sensitive gums, that trade still makes sense — it's the cheapest route to a fresh head any week of the year.

If your Sonicare takes a screw-on head rather than a click-on collar, the shelf is thin: Philips still sells the genuine E-Series head in a two-pack, and past that it's compatible makers like Aoremon. Six heads for the Advance, Essence, Elite, CleanCare and Xtreme handles is why this pack made the list.

Each head arrives in its own hygienic cap, which is more useful than it sounds — a capped spare goes into a gym bag without a plastic case around it. The bristles are medium and densely packed with rounded tips, and the thread is the part that has to be right: a head that cross-threads or sits high will wobble no matter how good the bristles are.

Durability is the weak point. Heads that fail within a few weeks of use turn up often enough that we treat this as a pack for the second brush rather than the one you use twice a day. For a travel bag, a spare handle or a brush you're not ready to replace, six capped heads in one box is still the practical choice — just watch the first one closely before you trust the rest.
