Quick facts
- United States: a sports mouthguard falls under the over-the-counter mouthguard product code OBR, or the prescription mouthguard code MQC, in the FDA device classification database.
- United States: both codes are unclassified and carry no regulation number, which is why a mouthguard is not described by a CFR section the way dental floss is.
- United States: the OBR definition covers protection of the teeth and reduction of damage from bruxing, which is why a sports guard and a night guard share one code family.
- Canada: a mouthguard placed in the oral cavity as far as the pharynx is Class I under the Medical Devices Regulations, Schedule 1, Rule 2(2).
- Canada: a mouthguard that is characterised as an orthodontic appliance, or as an accessory of one, is Class II under Rule 3(a).
- Both countries: the fit is the clinical variable. A guard that is worn is a guard that protects, and a guard that is uncomfortable is removed during play.
A sports mouthguard is the dental product most often bought by the case, ordered for a team or a school programme, and returned to the practice when a player complains that it does not fit. Its regulatory position is undramatic on both sides of the border — an unclassified product code in the United States and a Class I device in Canada — which is precisely why the clinical and record-keeping questions matter more than the classification. This article sets out how each country treats a mouthguard, what changes the Canadian class, and what a practice should hold for a team order.
How do Canada and the United States classify a sports mouthguard?
In the United States the mouthguard is classified by the product code that fits it. The FDA classification database lists an over-the-counter mouthguard under code OBR and a prescription mouthguard under code MQC, and both are unclassified with no regulation number. There is no CFR section for a mouthguard in the way that there is for dental floss, which sits in 21 CFR 872.6390 as a named Class I entry. That absence is not a gap in regulation; it is the classification the code records.
The OBR definition covers the sports case alongside the bruxism case, because it describes a device intended to protect the teeth and reduce damage. A practice that supplies a guard for a sport is therefore working inside the over-the-counter code, and a guard that is made to a prescription sits under the prescription code instead.
Canada classifies by rule. Rule 2(1) places invasive devices that penetrate the body through a body orifice in Class II, and Rule 2(2) then moves a device in the oral or nasal cavities as far as the pharynx into Class I. A mouthguard worn over the teeth is a device in the oral cavity, so it is Class I under Rule 2(2). Rule 3(a) is the exception that matters: "all denture materials and orthodontic appliances, and their accessories, are classified as Class II," so a guard characterised that way is Class II.
| Item | Canada | United States |
|---|---|---|
| Named entry | Rule 2(2) for an oral cavity appliance | Product code OBR or MQC |
| Regulation number | Rule-based, no section number | None; the codes are unclassified |
| Class | Class I for a plain guard; Class II if an orthodontic or denture accessory | Unclassified |
| Premarket submission | Device licence required for Class II; not for Class I | Determined by the product code and the applicable requirements |
| Fit record | Retained by the practice or the laboratory | Retained by the practice or the laboratory |
| Layer of protection | The guard in the mouth | The guard in the mouth |
Do Canada and the United States give sports mouthguards the same class as night guards?
They share a code family in the United States and a rule in Canada, and they do not share an indication. The United States places them under the same over-the-counter and prescription mouthguard codes, and the OBR definition names tooth protection and bruxism in one sentence. Canada reaches both through Rule 2(2) as oral cavity appliances, and both are Class I unless Rule 3(a) applies.
The difference that survives is clinical. A night guard is worn overnight against grinding and is made to a bruxism diagnosis; a sports guard is worn during activity and is made to absorb impact. A practice that stocks both should keep the indications apart in its records, because a guard described as a bruxism appliance and one described as a sports protector carry different clinical purposes even when they carry the same class.
| Guard type | Canadian class | United States code | Primary indication |
|---|---|---|---|
| Over-the-counter sports guard | Class I, Rule 2(2) | OBR, unclassified | Impact protection during sport |
| Custom sports guard, prescription | Class I, Rule 2(2) | MQC, unclassified | Impact protection, fitted |
| Custom night guard | Class I, Rule 2(2) | OBR or MQC, unclassified | Bruxism and grinding |
| Orthodontic or denture accessory | Class II, Rule 3(a) | Classified with the device | Treatment support |
What does the fit standard cover?
The performance of an athletic mouth protector is described by ASTM F2397, the standard specification for athletic mouth protectors, which addresses the material and performance expectations for a guard used in sport. The standard is a product specification rather than a regulation, and it is the reference behind a supplier claim that a guard is a compliant athletic protector.
For a practice, the standard and the classification answer different questions. The classification says what the device is and what paperwork follows it; the specification says what the material must do. A team order that records both — the class and the specification the guard is made to — is an order that can be defended when a parent or a coach asks what was supplied.
How should a practice document a team mouthguard order?
Five records, each tied to a requirement.
- The guard type. Over-the-counter or custom, and the sport or activity it is intended for, which supports the indication.
- The material and specification. The material used for the guard and the specification it is made to, so that a performance claim can be traced.
- The fit record. The impression or scan date and the fit check, because fit is what determines whether the guard is worn.
- The intended-use statement. The words supplied to the patient, because that statement decides the US code and the Canadian rule.
- The remake and hygiene record. The remake history and the cleaning instructions given to the patient, since a guard that is stored badly is a guard that is remade.
How should a mouthguard be cleaned and stored?
A mouthguard spends most of its life in a case, and the case is where the problems start. A guard stored wet in a closed container grows biofilm, and a guard that is cleaned with a hot rinse or left on a dashboard warps and stops fitting. The hygiene instruction a practice gives is therefore part of the clinical outcome, because a guard that is uncomfortable or unhygienic is a guard that is not worn.
Four points cover the instruction sheet. The first is mechanical cleaning: a soft brush and cool water, with a mild soap where the manufacturer allows it, and no boiling water. The second is drying before storage, because a guard stored wet keeps the moisture that organisms need. The third is the case itself, which should be vented and cleaned on the same schedule as the guard. The fourth is the replacement interval, which depends on the material and on how heavily the patient grinds, and which should be recorded so that a wear review can be scheduled rather than left to chance.
For a team or school programme, the same four points become a handout. A programme that supplies a guard without an instruction sheet and a replacement interval is supplying a device that will be used less than it could be, and the clinical value of the order depends on the instruction as much as on the material.
Which consumables sit beside the mouthguard line on a dental order?
Dental consumables are ordered as a cycle, and the mouthguard line travels with the impression, isolation and chairside consumables that share the same case. For 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 CliniEco dental range gathers the impression and isolation consumables, and a practice that wants the mouthguard and impression lines together can start from the moldable night guard two-pack, the dental dam sheets or the biological indicator five-pack trial for practices that also run their own sterilizer.

Frequently Asked Questions
What class is a sports mouthguard in the United States?
It is unclassified. A sports guard falls under the over-the-counter mouthguard product code OBR, or the prescription code MQC, and neither code carries a regulation number.
What class is a sports mouthguard in Canada?
Class I under Schedule 1, Rule 2(2), because it is a device placed in the oral cavity as far as the pharynx. It becomes Class II under Rule 3(a) if it is a denture material or an orthodontic appliance, or an accessory of either.
Do sports guards and night guards share a classification?
They share the US product code family and the Canadian Rule 2(2) route. What differs is the indication: impact protection during sport for one, bruxism and grinding for the other.
Which standard covers athletic mouth protectors?
ASTM F2397, the standard specification for athletic mouth protectors, addresses the material and performance expectations for a guard used in sport. It is a product specification rather than a regulation.
Why does fit matter so much for a mouthguard?
Because a guard that is uncomfortable is a guard that is removed during play. Fit is the variable that decides whether the protection is actually worn, which is why the impression and fit records matter.
What should a practice hold for a team mouthguard order?
The guard type and activity, the material and specification, the fit record, the intended-use statement, and the remake and hygiene records.
