Quick facts

United States: the rubber dam and its accessories have a named entry at 21 CFR 872.6300, and the section states that the device "includes the rubber dam, rubber dam clamp, rubber dam frame, and forceps for a rubber dam clamp".
United States: the section places the devices in Class I (general controls) and exempts them from premarket notification subject to the limitations in 872.9, with a conditional quality system carve-out for devices not represented as sterile.
United States: the section contains an express exclusion. It "does not include devices intended for use in preventing transmission of sexually transmitted diseases through oral sex; those devices are classified as condoms" under 21 CFR 884.5300.
Canada: Schedule 1 to the Medical Devices Regulations, SOR/98-282 names no rubber dam. The clamp, frame and forceps are dental instruments and Rule 3(b) places all surgical or dental instruments in Class I.
Canada: the dam sheet itself is not an instrument; it is a non-invasive device, and Rule 7(1) places all other non-invasive devices in Class I. Either route gives Class I.
Canadian regulation text used here is current to 2026-09-21 and last amended 2026-06-17, as stated on the official consolidation; the American section was last amended 90 FR 55984, December 4, 2025.

A rubber dam kit is a sheet, a frame, a clamp and a pair of forceps. It is used to isolate a tooth from the mouth during a restoration, and it is stored in a drawer with the other isolation supplies. In the United States the whole kit sits in one named section, and that section contains a sentence almost no one reads: it says what the section does not cover. In Canada the sheet and the metal parts are reached by different rules that happen to give the same class.

Are rubber dam clamps Class I in both Canada and the United States?

Yes, but the Canadian route splits the kit while the American section keeps it together.

The American section identifies the device as "a thin sheet of latex with a hole in the center intended to isolate a tooth from fluids in the mouth during dental procedures, such as filling a cavity preparation", stretched around a tooth by inserting the tooth through the hole, and then lists what the classification includes: the rubber dam, the rubber dam clamp, the rubber dam frame and the forceps for a rubber dam clamp. Section 872.6300(b) places the whole set in Class I and exempts it from premarket notification subject to 872.9, adding that devices not labelled or otherwise represented as sterile are exempt from the quality management system regulation in part 820 except for requirements concerning records and complaint files.

Canada separates the parts. The clamp, the frame and the forceps are instruments, and Rule 3(b) provides that all surgical or dental instruments are classified as Class I. The dam sheet is not an instrument at all; it is a non-invasive device laid across the tooth and the surrounding tissues, so Rule 7(1) applies and places all other non-invasive devices in Class I. The class is the same for both halves of the kit, but it comes from two different sentences, and a Canadian practice that describes the whole kit under one rule is describing it loosely.

Item	Canada	United States
Named entry for a rubber dam kit	None in Schedule 1	872.6300, rubber dam and accessories
Route for the clamp, frame and forceps	Rule 3(b), surgical or dental instruments, Class I	872.6300, Class I, general controls
Route for the dam sheet	Rule 7(1), other non-invasive devices, Class I	Same section as the accessories
Premarket notification	Not applicable at Class I under these rules	Exempt, subject to the limitations in 872.9
Sterility representation	Does not change the class	Changes which quality system requirements apply
Look-alike product marketed for another purpose	Not addressed by these rules	Excluded; classified as a condom under 884.5300

Why does the United States write an exclusion into the section that Canada reaches by its general rules?

Because the American framework classifies by intended use, and the exclusion writes that principle into the section rather than leaving it to be inferred.

The sentence is explicit: the classification "does not include devices intended for use in preventing transmission of sexually transmitted diseases through oral sex; those devices are classified as condoms in section 884.5300 of this chapter." The article may be a thin latex sheet with a hole in it, and if its stated purpose is barrier protection during oral sex, it is not a rubber dam under 872.6300. The same physical object changes section with the claim.

Canada reaches the same place by a different mechanism. The Medical Devices Regulations classify a device by its intended use, and a product placed on the market as a barrier for infection prevention is described by that purpose rather than by the dental isolation workflow. The Canadian framework does not need a sentence in the rubber dam rule to achieve this, because the classification rules do not begin from a product name.

The practical reading for a buyer is that a product name is not a classification. A practice that orders a latex sheet for isolation is buying a dental item; a supplier that markets the same sheet for another purpose is selling something the dental section does not cover, in the United States expressly.

What does a Canadian practice record for a Class I rubber dam kit?

Five records, and the two that mention sterility are the ones that most often go missing.

The intended clinical use. Isolation of a tooth during a restoration, stated on the file rather than inferred from the product name.
The kit list. The dam, the clamp, the frame and the forceps as separate line items, so a damaged clamp can be withdrawn without discarding the kit.
The clamp inventory. The clamp sizes and types held, since a clamp that does not seat correctly is a clinical problem rather than a regulatory one.
The reprocessing record. Which items in the kit are single use and which are reused, and the cycle and monitoring result for each reused item.
The sterility statement. The form in which sterility is claimed for the dam sheet, kept with the batch record rather than left in the catalogue.

Which consumables does an isolation tray restock alongside its rubber dam kit?

Isolation supplies and the consumables that run with them are ordered on the same cycle. For dental practices buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers. The cotton rolls cover moisture control at the field, the dental bibs cover the chairside surface, and practices that run their own steriliser can pair the monitoring collection with the biological indicator 5-pack trial.

A dam kit is not much use without a record that says it was processed. The printable clamp-cycle log is a free A4 form with a release column that can carry the clamp type beside the cycle it was run in. The generator sized to daily clamp loads builds that sheet from the number of cycles a practice runs and the items in each load, which keeps a clamp that is used twice a day from being logged on a form built for a hospital. No account and no sign-up are needed to open either one.

Where the product name and the intended use do not line up, the written answer is the one worth having. Ask a compliance specialist and a written answer comes back specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions

Are rubber dam clamps Class I in Canada?

Yes. A clamp, a frame and the forceps are dental instruments, and Rule 3(b) of Schedule 1 to the Medical Devices Regulations places all surgical or dental instruments in Class I. The dam sheet itself is a non-invasive device and Rule 7(1) also places it in Class I.

Why does the American section mention condoms?

Because the section excludes devices intended for use in preventing transmission of sexually transmitted diseases through oral sex, which are classified as condoms under section 884.5300. The exclusion turns on the intended use rather than on the physical design.

Does the sterility claim change the class?

No. Class I is unchanged on both sides of the border. In the United States, section 872.6300 exempts devices not labelled or otherwise represented as sterile from the quality management system regulation in part 820 except for requirements concerning records and complaint files.

Is the dam sheet classified the same way as the clamp in Canada?

The class is the same, but the route is not. The clamp is reached as an instrument under Rule 3(b), while the sheet is reached as a non-invasive device under Rule 7(1).

What should a practice keep for a rubber dam kit?

The intended clinical use, a kit list with the dam, clamp, frame and forceps as separate items, the clamp sizes held, the reprocessing record for each reused item, and the form in which sterility is claimed for the sheet.
