Sensodyne Repair and Protect Toothpaste, 3.4 oz - Stannous Fluoride Relief for Sensitive Teeth

Sensodyne Repair and Protect Toothpaste, 3.4 oz, uses 0.454% stannous fluoride (0.15% w/v fluoride ion) to build protection for sensitive teeth and prevent cavities. For adults with tooth sensitivity, its daily use focuses on enamel care and lasting comfort.

Sensodyne Repair and Protect Toothpaste, 3.4 oz, is designed for adults in the United States who live with tooth sensitivity and want daily enamel care without changing their entire oral care routine. The paste uses 0.454% stannous fluoride, corresponding to 0.15% w/v fluoride ion, to form a protective layer over exposed dentin while providing anticavity protection during regular twice-daily brushing. In a standard 3.4-ounce tube, it fits in most household medicine cabinets and travel kits while delivering a focused formulation for hypersensitive teeth.

Formulation Focused on Sensitivity Relief

The core of Sensodyne Repair and Protect Toothpaste is its stannous fluoride system. According to over-the-counter labeling data, the active ingredient is stannous fluoride 0.454%, with a fluoride ion concentration of 0.15% w/v, placing it firmly in the range commonly used for adult anticavity toothpastes that also target hypersensitivity. This active level is stated for products labeled as anticavity and antihypersensitivity pastes, combining cavity protection with sensitivity relief. The formulation builds increasing protection against painful sensitivity to cold, heat, acids, sweets or physical contact when used on a regular schedule as part of daily oral hygiene.

Alongside the active ingredient, typical excipients listed for Sensodyne Repair and Protect Toothpaste include hydrated silica as an abrasive, glycerin and PEG-8 as humectants, as well as surfactants such as sodium lauryl sulfate and cocamidopropyl betaine. These components support cleaning, foam formation and paste consistency while the stannous fluoride lays down a reparative layer on exposed tooth surfaces. The tube is presented as a paste format for adults 12 years of age and older, reinforcing that it is not formulated for children below this age group without a professional recommendation.

Tub Size, Fluoride Level and Daily Use

In the US, Sensodyne Repair and Protect Toothpaste is sold in a 3.4-ounce tube, a size that occupies the same shelf space as many other adult toothpastes but is clearly positioned as a sensitivity product. Retail packaging typically states a net weight of 3.4 ounces, with a single tube per unit. Directions published on drug information labels specify that adults and children 12 years of age and older apply at least a 1-inch strip of the product to a soft-bristle toothbrush and brush thoroughly for about one minute twice a day, with care taken to cover sensitive areas. This regimen corresponds to the use schedule needed to build up the stannous fluoride protective layer and maintain both sensitivity relief and cavity prevention over time.

On label and retail descriptions, the product is classified as both anticavity and antihypersensitivity. That dual indication explains why the fluoride concentration is set at 0.454% stannous fluoride with 0.15% w/v fluoride ion: the level is sufficient to secure fluoride-based cavity protection while allowing the stannous ion to interact with exposed dentin, forming a mineral-rich barrier. Unlike formulations that rely solely on potassium nitrate for sensitivity relief, this paste uses stannous fluoride as its primary active ingredient and emphasizes the reparative layer it creates on vulnerable tooth surfaces.

Pricing and Unit Cost in US Retail

In US drugstore and mass retail channels, Sensodyne Repair and Protect Toothpaste in the 3.4-ounce size is positioned in the upper band of mainstream toothpaste prices but remains accessible as an everyday purchase. A recent listing for a closely related stannous fluoride sensitivity paste with the same 3.4-ounce tube format showed a price of $9.99 and a unit cost of $2.94 per ounce (as of 09/10/2026) from a large general merchandise retailer. That unit price aligns with typical sensitivity and specialty toothpaste ranges rather than the lower prices associated with standard fluoride-only cavity prevention pastes.

Other listings for Sensodyne Repair and Protect-branded pastes with similar tube sizes report prices in the single-digit or low double-digit dollar range per tube, depending on retailer and promotional status. For example, a 3.4-ounce sensitivity toothpaste using stannous fluoride as its primary active ingredient and marketed for daily enamel care and lasting relief has been offered at $9.99 with a per-ounce cost indicated directly on the product detail page, putting it into the midrange of sensitivity-focused oral care products. This price level reflects the formulation emphasis on stannous fluoride-based sensitivity relief and the brand positioning within the sensitive-teeth niche.

Brand Ownership and US Manufacturer Entity

Sensodyne Repair and Protect Toothpaste is part of the Sensodyne brand, a longstanding line of toothpastes marketed for people with sensitive teeth. Sensodyne is owned by Haleon, the consumer healthcare company formed as a separate entity through a spin-off from GSK in July 2022. Public brand overviews list Haleon as the current owner of Sensodyne, noting that the brand is distributed globally under different names in specific markets. In English-language references, Sensodyne is consistently associated with Haleon as a consumer health brand focusing on oral care for sensitivity.

In the United States, over-the-counter labeling data for Sensodyne Repair and Protect Toothpaste identifies GlaxoSmithKline Consumer Healthcare Holdings (US) LLC as the labeler. This entity functions as the US manufacturer or distributor for the toothpaste, handling regulatory registration and packaging details for the domestic market. That pairing reflects the historical connection between GSK consumer healthcare operations and the Haleon brand portfolio, with the US company name still appearing on drug information records for Sensodyne-branded products.

Comparison With Other Sensodyne Sensitivity Pastes

Within the sensitivity toothpaste category, Sensodyne Repair and Protect Toothpaste competes directly with other stannous fluoride-based products and also with formulations that combine potassium nitrate and sodium fluoride. A nearby option on US retail shelves is Sensodyne Clinical Repair Fluoride Toothpaste, Fresh Clean, in the same 3.4-ounce size. This Clinical Repair product shares the same primary active ingredient level of stannous fluoride 0.454% (0.15% w/v fluoride ion) but is frequently priced at $9.99 with a per-ounce cost around $2.94 (as of 09/10/2026), placing it close to the price band of Sensodyne Repair and Protect.

The similarity in tube size and active ingredient concentration means that both Repair and Protect and Clinical Repair aim to build reparative protection against sensitivity, but they may differ in flavor positioning and specific marketing claims. Clinical Repair is often presented with a fresh clean taste and a focus on enamel repair, while Repair and Protect emphasizes ongoing sensitivity relief and daily enamel care. Compared with standard cavity-protection toothpastes that use sodium fluoride alone, both Sensodyne sensitivity products carry higher per-ounce prices, reflecting their specialized formulation and branding for people who experience painful sensitivity.

Context in Daily Oral Care and Use Case Assessment

As an everyday toothpaste for adults with sensitive teeth, Sensodyne Repair and Protect Toothpaste occupies a clear slot in the oral care routine: it replaces a regular fluoride paste while preserving cavity prevention and adding antihypersensitivity protection. The 3.4-ounce tube size is familiar, and the stannous fluoride concentration of 0.454% with 0.15% w/v fluoride ion matches the levels documented for sensitivity-focused anticavity pastes that rely on fluoride-based mechanisms rather than potassium nitrate. The anticavity and antihypersensitivity indications on the label underscore its dual function for users who want both protection and relief.

In the broader category, Repair and Protect makes the most sense for adults who report frequent twinges of pain from hot, cold, sweet or acidic foods and drinks and prefer to address that sensitivity through their toothpaste choice rather than adding gels or rinses. When compared with alternatives like Sensodyne Clinical Repair or potassium nitrate-based enamel repair pastes, the deciding factors often become flavor profile, price per ounce and trust in the stannous fluoride mechanism. For those who prioritize a reparative barrier on exposed dentin and are comfortable with the slightly higher price band, Sensodyne Repair and Protect Toothpaste fits neatly into a long-term daily use case aimed at managing sensitivity while maintaining fluoride-based cavity defense.
