Is Toothpaste an OTC Drug? — FDA Compliance Guide
This guide explains the exact legal test for each classification, the specific fluoride concentrations permitted under 21 CFR Part 355, Drug Facts labeling requirements, sensitivity and anti-gingivitis claim rules, NDC numbers, and what MoCRA requires for cosmetic-only toothpaste.
How FDA Classifies Toothpaste — The Full Classification Map
The classification is determined by two questions: (1) Does the product contain a recognized OTC monograph active ingredient? (2) Does it make drug claims? If either answer is yes, it is an OTC drug. Here is the full classification map for every common toothpaste type:
| Toothpaste Type | Classification | Governing Regulation | Required Compliance |
|---|---|---|---|
| Fluoride toothpaste (cavity prevention) | OTC Drug | 21 CFR Part 355 — Anticaries monograph | Drug Establishment Registration, SPL drug listing, NDC number, Drug Facts panel, annual renewal |
| Fluoride toothpaste (sensitivity) | OTC Drug | Anticaries monograph + sensitivity provisions | Same as above. Active ingredient: potassium nitrate 5% or stannous fluoride 0.15% |
| Fluoride toothpaste + whitening | OTC Drug + Cosmetic | 21 CFR Part 355 + MoCRA | Drug Establishment Registration + drug listing + Drug Facts panel PLUS MoCRA facility registration + product listing + INCI labeling |
| Fluoride toothpaste + tartar control | OTC Drug | 21 CFR Part 355 | Tartar control claim is permissible alongside anticaries claim. Drug requirements apply. Non-active tartar control ingredients (pyrophosphates) declared in inactive ingredients. |
| Whitening toothpaste (fluoride-free, no drug claims) | Cosmetic (MoCRA) | MoCRA + 21 CFR Part 701 | Annual MoCRA facility registration, product listing, INCI labeling, safety substantiation, CSCAR adverse event reporting |
| Natural/herbal toothpaste (no fluoride, no drug claims) | Cosmetic (MoCRA) | MoCRA + 21 CFR Part 701 | Same MoCRA requirements. Any drug claim (cavity prevention, gingivitis) converts to unapproved new drug — serious violation |
| Anti-gingivitis toothpaste (stannous fluoride) | OTC Drug | 21 CFR Part 355 + anti-gingivitis provisions | Stannous fluoride 0.15% supports both anticaries and limited anti-gingivitis claims. Full drug establishment and listing requirements apply. |
| Children's fluoride toothpaste | OTC Drug | 21 CFR Part 355 | Same drug requirements. Drug Facts panel must include age-specific directions for children under 6 and children under 2. |
The Anticaries Monograph — Permitted Active Ingredients and Concentrations
The Anticaries Drug Products for Over-The-Counter Human Use monograph at 21 CFR Part 355 is the governing regulation for fluoride toothpaste. It specifies which fluoride active ingredients are permitted, at what concentrations, and what claims may be made. A toothpaste with fluoride at concentrations above the monograph limits — or using a fluoride form not listed in the monograph — requires an approved New Drug Application (NDA) rather than OTC monograph compliance.
| Active Ingredient | Permitted Concentration | Fluoride Ion | Key Notes |
|---|---|---|---|
| Sodium Fluoride (NaF) | 0.22% w/w | ~1,000 ppm F⁻ | Most common fluoride active. Must be declared as "Sodium Fluoride 0.22%" in Drug Facts. Provides 0.15% w/v fluoride ion. |
| Sodium Monofluorophosphate (MFP) | 0.76% w/w | ~1,000 ppm F⁻ | Common in European-origin formulas. Must be declared as "Sodium Monofluorophosphate." Delivers fluoride through enzymatic breakdown in saliva. |
| Stannous Fluoride (SnF₂) | 0.15% w/w (available F) | ~1,000 ppm F⁻ | Provides both anticaries and anti-gingivitis/plaque reduction benefits. Must include stabilization system. Declared as "Stannous Fluoride (0.15% available fluoride)". |
Fluoride concentrations above 1,100 ppm are not covered by the OTC monograph and require an NDA. Prescription-strength fluoride toothpastes (typically 5,000 ppm) are classified as prescription drugs and cannot be marketed OTC.
Drug Facts Panel Requirements for OTC Toothpaste
The Drug Facts panel is the most critical labeling element for OTC toothpaste compliance. It must appear under 21 CFR Part 201.66 in a specific order with specific font sizes, type styles, and format. The elements must appear in this exact sequence:
Required Drug Facts Elements — In Order
1. Active ingredient(s) — with percentage and purpose (e.g., "Sodium Fluoride 0.22% w/w · Anticavity")
2. Uses — permitted drug claims from the monograph
3. Warnings — including "Keep out of reach of children under 6 years of age" and the specific fluoride overdose warning: "If more than used for brushing is accidentally swallowed, get medical help or contact a Poison Control Center right away"
4. Directions — by age group (adults/children 2+; children under 6; children under 2: ask dentist or doctor)
5. Other information — optional storage or other product information
6. Inactive ingredients — listed in alphabetical order using INCI-compatible names
Common Drug Facts Labeling Violations
Active ingredient declared without percentage concentration · Purpose missing or incorrect · Uses include claims not permitted by the monograph · Fluoride overdose warning absent or wrong wording · Age-specific directions missing for children under 6 · Inactive ingredients not in alphabetical order · Font size below minimum requirements · Drug Facts panel too small on the package · Drug Facts label on product where cosmetic ingredient list should also appear (for combination products)
Sensitivity and Anti-Gingivitis Toothpaste — What FDA Recognizes
Sensitivity Claims
FDA recognizes two active ingredients for the sensitive teeth OTC claim: potassium nitrate at 5% w/w and stannous fluoride at 0.15% w/w. Potassium nitrate must be listed as the active ingredient with purpose "Antihypersensitivity." The recognized claim language includes "builds increasing protection against painful sensitivity of the teeth to cold, heat, acids, sweets, or contact." A sensitivity claim using potassium nitrate at a concentration other than 5% is not monograph-compliant and requires an NDA.
Anti-Gingivitis Claims
Stannous fluoride at 0.15% supports limited anti-gingivitis and plaque reduction claims alongside its anticaries function — without requiring a separate NDA — because stannous fluoride's antibacterial properties are recognized. Claims such as "helps prevent gingivitis" and "helps reduce plaque that leads to gingivitis" are permitted with stannous fluoride. The anti-gingivitis OTC monograph was proposed but not fully finalized. Toothpastes making anti-gingivitis claims without a recognized active ingredient are unapproved new drugs.
Complete FDA Compliance Checklist for OTC Toothpaste
1. Drug Establishment Registration
Any facility manufacturing, processing, packing, or labeling OTC toothpaste must register under 21 CFR Part 207. Annual renewal October 1 – December 31 every year. Foreign facilities must designate a U.S. Agent. Drug Establishment Registration is annual — unlike food facility biennial renewal.
2. Drug Listing via DRLM
Each OTC toothpaste product must be listed through the DRLM portal at access.fda.gov in SPL (Structured Product Labeling) XML format. Listing includes formulation, active ingredients, NDC number, Drug Facts labeling content, dosage form, and packaging. Updated within 30 days of any product change.
3. NDC Number
Each distinct toothpaste product requires its own NDC (National Drug Code) number — assigned through the drug listing process. Different flavors, sizes, and formulations each need a separate NDC. The NDC number must appear on the label. FDA Registration Assistance manages NDC number assignment as part of the drug listing process.
4. Drug Facts Labeling
Drug Facts panel under 21 CFR Part 201.66 in the mandatory order: active ingredient(s) and purpose; uses; warnings (including fluoride overdose warning); directions (age-specific); other information; inactive ingredients. Correct font size, type style, and format are regulatory requirements — not design preferences.
5. Monograph Compliance
Active ingredient must be one of the three permitted fluoride forms under 21 CFR Part 355 at the permitted concentration. Drug claims must match the permitted claim language from the monograph. Claims not covered by the monograph require an approved NDA before any marketing.
6. MoCRA (If Cosmetic Functions)
Fluoride toothpaste with whitening claims is both an OTC drug and a cosmetic. MoCRA annual facility registration, product listing, and INCI-compliant labeling must be completed simultaneously with the drug compliance pathway. FDA Registration Assistance manages both pathways for combination products.

Frequently Asked Questions — Is Toothpaste an OTC Drug?
1. Is toothpaste an OTC drug?
It depends on formulation and claims. Fluoride toothpaste is an OTC drug under 21 CFR Part 355. Toothpaste with no fluoride and no drug claims is a cosmetic under MoCRA. Most commercial toothpastes are both simultaneously — the fluoride makes them OTC drugs, and whitening or breath-freshening functions make them cosmetics.
2. What is the governing regulation for fluoride toothpaste?
The Anticaries Drug Products monograph at 21 CFR Part 355. It specifies the three permitted fluoride active ingredients (sodium fluoride, sodium monofluorophosphate, stannous fluoride), their permitted concentrations (~1,000 ppm fluoride), permitted drug claims, Drug Facts labeling requirements, and age-specific directions.
3. What fluoride concentrations are permitted in OTC toothpaste?
Under 21 CFR Part 355: sodium fluoride at 0.22% w/w; sodium monofluorophosphate at 0.76% w/w; stannous fluoride at 0.15% w/w (available fluoride). All three provide approximately 1,000 ppm fluoride ion. Concentrations above 1,100 ppm require an NDA — not OTC monograph compliance.
4. What drug claims can OTC fluoride toothpaste make?
Under the Anticaries monograph: preventing tooth decay, helping prevent cavities, building and strengthening tooth enamel, and reducing dental caries incidence. Stannous fluoride additionally supports anti-gingivitis and plaque reduction claims. Tartar control claims are permissible with fluoride toothpaste. Claims treating existing disease require an NDA.
5. When is toothpaste regulated as a cosmetic under MoCRA?
When it contains no OTC drug active ingredients and makes only cosmetic claims — whitening, freshening breath, cleaning teeth. Annual MoCRA facility registration, product listing, INCI labeling, safety substantiation, and CSCAR adverse event reporting are required. No Drug Facts panel; cosmetic ingredient list using INCI names required under 21 CFR Part 701.3.
6. Can toothpaste be both an OTC drug and a cosmetic?
Yes — and it's the most common scenario. Fluoride whitening toothpaste is simultaneously an OTC drug (for anticaries fluoride) and a cosmetic (for whitening). Both Drug Establishment Registration + drug listing + Drug Facts panel AND MoCRA registration + product listing + INCI labeling must be completed simultaneously.
7. What are the sensitivity toothpaste active ingredients?
FDA recognizes potassium nitrate at 5% w/w (purpose: Antihypersensitivity) and stannous fluoride at 0.15% w/w for sensitive teeth claims. Potassium nitrate at any concentration other than 5% is not monograph-compliant. Stannous fluoride at 0.15% covers both anticaries and sensitivity claims.
8. What is the Drug Facts labeling requirement for OTC toothpaste?
Under 21 CFR Part 201.66, Drug Facts must appear in mandatory order: Active ingredient(s) + purpose; Uses; Warnings (including fluoride overdose warning and "Keep out of reach of children under 6"); Directions by age group; Other information; Inactive ingredients (alphabetical). Specific font sizes and formats are mandatory requirements.
9. Does OTC toothpaste require Drug Establishment Registration?
Yes. All facilities manufacturing, processing, packing, or labeling OTC drug toothpaste must register under 21 CFR Part 207. Annual renewal October 1 – December 31 every year. Foreign facilities must designate a U.S. Agent under 21 CFR Part 207.69.
10. What is SPL drug listing for toothpaste?
Every OTC drug toothpaste product must be listed with FDA in Structured Product Labeling (SPL) XML format through the DRLM portal at access.fda.gov. SPL includes active ingredients and concentrations, NDC number, Drug Facts labeling content, formulation details, and the establishment's registration number. Updated within 30 days of any product changes and during the annual October–December window.
11. Does OTC toothpaste need an NDC number?
Yes. Each distinct OTC drug toothpaste product requires its own NDC number — assigned through the drug listing process. Different flavors, sizes, and formulations each need a separate NDC. The NDC number must appear on the toothpaste label.
12. Are tartar control claims permitted on OTC toothpaste?
Yes. Tartar control claims are permissible alongside anticaries claims for fluoride toothpaste. Tartar control benefit is provided by inactive ingredients (pyrophosphates, zinc citrate) and does not require a separate drug active ingredient or NDA. The product remains primarily an OTC drug due to the fluoride active ingredient.
13. What is the difference between Drug Facts and INCI cosmetic labeling?
Drug Facts (under 21 CFR Part 201.66) lists active ingredients separately, declares purpose, uses, warnings, and directions in a mandatory format. INCI cosmetic labeling (under 21 CFR Part 701.3) lists all ingredients in descending order by weight using INCI names. A combination OTC drug + cosmetic toothpaste uses a Drug Facts panel — the inactive ingredients section uses INCI names.
14. Does anti-gingivitis toothpaste require a separate NDA?
Not if using stannous fluoride at 0.15% — this active ingredient supports limited anti-gingivitis claims alongside its anticaries function. However, toothpaste making anti-gingivitis claims with an active ingredient not covered by existing monographs may require an NDA. The anti-gingivitis monograph was proposed but not fully finalized.
15. How often must Drug Establishment Registration be renewed for toothpaste?
Annually — October 1 through December 31 every year under 21 CFR Part 207.29. Unlike FDA Food Facility Registration (biennial), drug registration is annual. Missing the window results in inactive registration status — a prohibited act under 21 U.S.C. § 331.
16. What happens if toothpaste is sold in the U.S. without OTC drug compliance?
Selling OTC drug toothpaste without Drug Establishment Registration, drug listing, and Drug Facts labeling violates 21 U.S.C. § 331. Consequences: import refusal at U.S. ports; FDA Warning Letters; product seizure; recall; Import Alert; and civil penalties. Applies equally to domestic manufacturers and importers.
17. Does a fluoride-free whitening toothpaste need MoCRA registration?
Yes. Fluoride-free whitening toothpaste with no drug claims is a cosmetic requiring annual MoCRA facility registration, individual product listing, INCI labeling, safety substantiation, and CSCAR adverse event reporting. No Drug Facts panel required — cosmetic ingredient list using INCI names under 21 CFR Part 701.3.
18. Can fluoride toothpaste make "whitening" claims?
Yes. Whitening is a cosmetic appearance claim that doesn't add a new drug function. The toothpaste then satisfies both OTC drug requirements (Drug Establishment Registration, drug listing, Drug Facts panel) and MoCRA cosmetic requirements (facility registration, product listing, INCI labeling) simultaneously.
19. What is the potassium nitrate concentration for sensitive toothpaste?
Potassium nitrate must be at exactly 5% w/w for the antihypersensitivity OTC claim. This is the only monograph-recognized concentration. Other concentrations require an NDA. Potassium nitrate at 5% must be listed as the active ingredient in the Drug Facts panel with purpose "Antihypersensitivity."
20. Does children's toothpaste have different FDA requirements?
Same OTC drug regulatory framework applies. The Drug Facts panel must include age-appropriate directions — children 2 years and older: pea-sized amount; children under 2: ask dentist or doctor. Fluoride-free children's toothpaste marketed without drug claims is a cosmetic subject to MoCRA.
21. What are the most common OTC toothpaste compliance failures?
Most common: treating fluoride toothpaste as a cosmetic and missing Drug Establishment Registration; missing annual renewal (October–December); Drug Facts panel in wrong format or missing required elements; NDC number not registered; sensitivity claims with wrong active ingredient concentration; anti-gingivitis claims without recognized active ingredient; and foreign manufacturers without a U.S. Agent.
22. Does the OTC toothpaste monograph cover natural or herbal toothpaste?
No. Natural toothpaste with charcoal, baking soda alone, neem, or botanicals without a monograph active ingredient is a cosmetic if it makes only cosmetic claims. If it makes drug claims (cavity prevention, gingivitis treatment) without a recognized OTC active ingredient, it becomes an unapproved new drug — a serious FDA violation.
23. Can toothpaste be sold in the U.S. as a cosmetic only?
Yes — if it contains no fluoride or other OTC drug active ingredients and makes only cosmetic claims. Such toothpaste is subject to MoCRA: annual facility registration, product listing, INCI labeling, safety substantiation. No Drug Facts panel. Fluoride-free whitening and natural toothpastes without drug claims fall into this category.
24. What is the U.S. Agent requirement for foreign toothpaste manufacturers?
Foreign OTC drug toothpaste manufacturers must designate a U.S. Agent under 21 CFR Part 207.69 with a physical U.S. address. The drug U.S. Agent has an active inspection facilitation role — assisting with inspection scheduling and coordination. FDA Registration Assistance provides U.S. Agent services for foreign toothpaste manufacturers.
