Oral-B Glide All-in-One Dental Floss
Lower concern, but Oral-B silent on Teflon-type coating.
This nylon floss widely uses Teflon-type coating polytetrafluoroethylene coating for its smooth, shred-resistant texture. Oral-B doesn't publicly disclose PFAS content or make PFAS-free claims.
We flunk more products than we pass. This one earned its grade. How we grade
Material
Nylon filament (Teflon-type coating-coated)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Nylon filament allergenicity or irritation
Nylon itself is inert, but users with latex allergy or sensitivity to synthetic polymers may rarely experience gum irritation. Switching to silk or uncoated alternatives is the practical recourse; no widespread reports exist for Glide specifically.
Ingestion of non-degradable polymer material
Accidental swallowing of a small amount of floss poses a mechanical (choking or blockage) rather than chemical hazard. This is a usage accident, not a product toxicity issue, and is extremely rare in adults.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Teflon-type coating degradation or shedding
No documented cases of Teflon-type coating flaking or ingestion from Oral-B Glide. The coating is bonded to nylon and not exposed to heat or mechanical stress that would cause breakdown in normal oral use.
Residual manufacturing additives or plasticizers
Nylon and Teflon-type coating do not require phthalates or BPA in their formulation. No public testing or recalls indicate leachable additives in Oral-B Glide; the product is not heated or stored for extended periods in the mouth.
Container or packaging leachables
Floss containers are typically polypropylene or plastic, not in direct prolonged contact with food or saliva. No hazard documentation exists for Oral-B floss packaging specifically.
The full breakdown
What it's made of and why it matters
Oral-B Glide All-in-One uses nylon filament coated with Teflon-type coating (polytetrafluoroethylene, brand name Teflon) to reduce friction and ease passage between teeth. The nylon core provides tensile strength; Teflon-type coating makes it slippery and resistant to shredding. Unlike cookware or non-stick surfaces exposed to heat, dental floss operates at mouth temperature and is used briefly, minimizing any risk of Teflon-type coating fume release or degradation. The product is designed to be used once and discarded, not reused or stored.
The brand's record and disclosure
Oral-B is owned by Procter & Gamble and is a mainstream oral-care manufacturer with no documented safety recalls specifically tied to Glide floss toxicity. The brand does not publicly disclose detailed ingredient sourcing or Teflon-type coating supplier information, which is typical for large consumer-goods companies but limits transparency. No independent testing controversies or regulatory warnings have been issued against this product. P&G has faced broader PFAS-in-products scrutiny across its portfolio but has not publicly committed to eliminating Teflon-type coating coatings in floss.
How it compares in its category
Most premium dental flosses (Glide, Reach, Crest) use Teflon-type coating or similar slip-coated nylon; uncoated nylon and natural silk alternatives exist but are less effective at sliding between tight contacts. Glide is one of the most widely used Teflon-type coating-coated flosses globally and has no higher reported incident rate than competitors. Waxed nylon floss (without Teflon-type coating) is a lower-PFAS alternative but offers less glide and may be less effective for some users. Oral-B Glide's market dominance reflects consumer preference for ease of use, not a safety advantage.
If you buy it
Use as directed: a short segment daily, disposed immediately after use. No heating, storage in extreme temperatures, or reuse is needed. Replace the container when floss becomes difficult to dispense or shows visible wear. Store in a cool, dry place to prevent humidity-induced container degradation. If gums bleed or show irritation after starting use, switch to an uncoated alternative; floss-related injury is mechanical (gum trauma), not chemical.
