Quick facts
- A manual toothbrush is a named Class I device in the United States at 21 CFR 872.6855.
- A powered toothbrush is a separate Class I entry at 21 CFR 872.6865.
- An ionic, battery-powered toothbrush is filed under the same 872.6865, and a powered radiofrequency toothbrush is Class II at 21 CFR 872.6866.
- Canada names no toothbrush: a disposable brush is a non-invasive device and reaches Class I through Rule 7(1) of the Medical Devices Regulations.
- The US class turns on the mechanism, not on how the brush looks.
- The regulation text cited here is current to 2026-09-21 and was last amended on 2026-06-17.
A disposable toothbrush is the small brush a clinic hands a patient before an examination, after a procedure, or in a hygiene kit. It looks like a toothbrush, because it is one. What makes it interesting for a buyer is that a US file can place two brushes that look identical in two different classes, while a Canadian file reaches the same place by rule for all of them.
What is a disposable toothbrush?
It is a single-use brush, usually pre-pasted or plain, that is given to a patient rather than kept for reuse.
Disposable brushes appear in three settings. A dental or medical examination room uses them to let a patient clean the mouth before an assessment. A hospital or long-term care ward uses them so that each patient has a personal brush that is not shared. A hygiene kit bundles them with a small paste and a cup. In each case the brush is used once and discarded, which is what makes the stock item a consumable rather than a durable good.
The clinical reasoning is the same in all three settings. A shared brush is a shared reservoir of oral flora, and a single-use brush removes that route. That is a hygiene decision, and it sits alongside the glove and the bib on the tray.
How do Canada and the United States classify a disposable toothbrush?
It is Class I on both sides, by a named entry on one and by rule on the other.
| Item | Canada | United States |
|---|---|---|
| Manual brush (disposable or durable) | Class I by Rule 7(1) | Class I, 21 CFR 872.6855 |
| Powered brush | Class I by Rule 7(1) | Class I, 21 CFR 872.6865 |
| Ionic, battery-powered brush | Class I by Rule 7(1) | Class I, 21 CFR 872.6865 |
| Powered radiofrequency brush | Class I by Rule 7(1) | Class II, 21 CFR 872.6866 |
| Basis named in the rulebook | Rule and use | Device entry, product code and mechanism |
In the United States a manual toothbrush is named at 21 CFR 872.6855 and a powered toothbrush at 21 CFR 872.6865, and each carries its own product code. Both are Class I. A powered radiofrequency toothbrush is named at 21 CFR 872.6866 and is Class II.
In Canada none of these is a named entry. A toothbrush is a non-invasive device that contacts the mouth without penetrating the mucosa, so Rule 7(1) places it in Class I. The Canadian route does not distinguish a manual brush from a powered one at the level of the rule, and it does not single out a radiofrequency brush. The distinction that matters in the United States is written into the entries; in Canada it is not.
Does a powered brush sit in a different class from a manual brush in Canada and the United States?
In the United States it can, and in Canada the class is the same unless the brush is connected to a higher-class active device.
| Brush | US entry | US class | Canadian basis | Canadian class |
|---|---|---|---|---|
| Manual, disposable | 21 CFR 872.6855 | Class I | Rule 7(1) | Class I |
| Powered (oscillating or sonic) | 21 CFR 872.6865 | Class I | Rule 7(1) | Class I |
| Ionic, battery-powered | 21 CFR 872.6865 | Class I | Rule 7(1) | Class I |
| Powered radiofrequency | 21 CFR 872.6866 | Class II | Rule 7(1), or Rule 7(2)(b) if connected | Class I, or Class of the connected device |
Two brushes on the same shelf can therefore be Class I and Class II in the United States. The difference is not the brand or the price; it is the mechanism. A brush that emits radiofrequency energy is treated as a higher-risk device than one that simply oscillates, and the entry reflects that. Canada reaches Class I by rule for all four, and only Rule 7(2)(b) can lift one, when the brush is intended to be connected to an active device in a higher class.
Why does the mechanism decide the class?
Because the class follows the energy a device delivers, not the part of the body it touches.
A brush that scrubs delivers mechanical action. A brush that emits radiofrequency energy delivers energy to tissue, and a device that delivers energy is assessed on a different footing from one that does not. The US entries make that split explicit: 872.6865 for the powered brush that oscillates or vibrates, and 872.6866 for the powered radiofrequency brush. Between them the class moves from I to II on the strength of the mechanism alone.
For a buyer this is a reason to read the description rather than the picture. A disposable manual brush for a tray is one thing; a powered brush sold to the same account is another, and the second may be in a higher class than the first even though the two are shelved together. The mechanism is the fact to check, and it is written on the entry.
Which consumables does a patient-kit room restock?
A tray that carries a disposable brush runs on the same chairside lines as the rest of the room. The 3-layer paper and PE dental bibs cover patients across a working day, and the cotton rolls in a 2000-piece box keep the field dry during a procedure. Where a practice monitors its own sterilisation cycle, the sterilization monitoring collection pairs with the 24-hour monitoring five-pack trial. Clinics and multi-site groups ordering at case level use the wholesale ordering page, and the B2B wholesale collection lists the lines held for institutional buyers. Reselling? become a distributor.
What belongs in a single-use patient kit?
The kit is judged by whether it lets a patient clean the mouth once, hygienically, without touching anything shared.
The core items are the disposable brush, a small paste or none if the clinician prefers, and a cup. In a ward the kit is often wrapped so that a carer can open it with one hand. In a dental examination room it is laid on the tray beside the bib, and the brush is discarded after use. The common thread is that every item is used once and nothing goes back into a drawer.
Two details decide whether the kit works. The first is that the brush is individually wrapped or dispensed so that it cannot be picked up by two patients in succession. The second is that the kit is restocked to a written count, so that a short tray is noticed in the morning rather than at the chair. A kit that is assembled from loose stock has no count, and a count that is never written has no way to show that it was met.
None of these items is in a high class on either side of the border, and that is exactly the point. A disposable brush, a cup and a bib are all devices, all in the lightest class, and all governed by rules rather than by a per-product approval. Buying them is a stock routine, not a registration exercise, and the record that matters is the one that shows the tray was ready.

A patient kit that is assembled without a record is a kit that cannot be checked. The printable patient kit log is a free sheet with columns for the room, the kit contents, the date restocked and the person responsible, so a shortage is seen before a patient is affected. The kit record generator on the same page sizes the sheet to the number of rooms a clinic runs. No account and no sign-up are needed to open either one.
A brush that looks ordinary can sit in a class set by its mechanism. Ask a compliance specialist and you will get a written answer specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions
Is a disposable toothbrush a device in the United States?
Yes. A manual toothbrush is a Class I device under 21 CFR 872.6855 and carries its own product code, whether it is disposable or durable.
What class is a powered toothbrush in the United States?
Class I. A powered toothbrush is named at 21 CFR 872.6865, and an ionic, battery-powered toothbrush is filed under the same number.
Which toothbrush is Class II in the United States?
A powered radiofrequency toothbrush is Class II under 21 CFR 872.6866. The class turns on the mechanism, not on how the brush looks.
Does Canada name a toothbrush?
No. A toothbrush is a non-invasive device, and Rule 7(1) of the Medical Devices Regulations places all other non-invasive devices in Class I. Canada reaches Class I by rule for manual and powered brushes alike.
Can a brush move into a higher class in Canada?
Only if it is intended to be connected to an active device in a higher class. Under Rule 7(2)(b) the brush then takes the class of that device.
Why does a clinic use a disposable brush at all?
Because a shared brush is a shared reservoir of oral flora, and a single-use brush removes that route. The decision is a hygiene decision, and it sits alongside gloves and a bib on the same tray.
