SP-8 Toothpaste: Whitening, Probiotics, Side Effects

What Is SP-8 Toothpaste?

SP‑8 Toothpaste—also seen as SP‑8 Ultra‑Whitening Toothpaste or SP‑8 Probiotic Toothpaste—is an oral care product aimed at whitening teeth and promoting fresh breath, blending a gentle formula with supposed probiotic benefits. It’s marketed through various online platforms under slightly differing names (e.g., “SP 8 Pasta de Dientes,” “AstraGlow SP‑8 Probiotic Toothpaste”) though specifics about the brand and manufacturer remain elusive .

Who Makes SP-8 Toothpaste?

Manufacturer details are scarce—GoSupps lists it as a “Generic” supplier, and Amazon vendors appear to be small third-party sellers with limited branding information. This lack of transparency may warrant caution, especially given consumer concerns raised in forums like Digital Spy:

“Seems to be unbranded toothpaste from China being sold by a multitude of other small sellers. I wouldn’t touch this with a barge‑pole.” 

Key Features & Benefits

From product listings, SP‑8 Toothpaste claims the following:

• Long-lasting freshness: Keeps breath fresh throughout the day .

• Strong cleaning: Made with “natural ingredients” for effective daily oral care .

• Gentle enough for everyday use, yet effective against surface stains .

However, independent reviews and clinical validation are lacking, and forum users caution reliance on such marketing alone .

Ingredients Overview

Specific ingredient details aren’t provided in the sources you shared. But some related common inquiries include:

• What is the function of PEG‑8 in toothpaste? PEG‑8 acts as a humectant or to improve texture and spreadability—helping formulate a smooth, non‑drying product.

• Is hydroxyapatite toothpaste safe? Hydroxyapatite is generally considered safe and beneficial for enamel remineralization compared to harsher abrasives or bleaches.

Without transparency from manufacturers, it’s hard to determine whether SP‑8 contains such additives or conventional detergents (SLS), abrasives, or fluoride.

Does SP-8 Toothpaste Really Work?

Effectiveness is uncertain. No third-party studies or robust user reviews validate its whitening or probiotic claims. Digital Spy users recommend:

“Ignore adverts… If anyone needs guidance on a suitable toothpaste then ask your Dentist.” 

This suggests that SP‑8’s efficacy remains anecdotal and should be scrutinized or discussed with dental professionals.

SP-6 vs SP-8 Toothpaste: What’s the Difference?

Though both variants are mentioned in searches (“SP6 vs SP8 toothpaste”), there’s no authoritative source comparing them. Typically, such designations might refer to ingredient concentrations or added whitening agents—but without manufacturer disclosure, this remains speculative.

Side Effects & Safety Concerns

There are no reported scientific or customer data on side effects. Users should err on the side of caution:

• Review the ingredient list (if available).

• Check for known irritants like SLS or high fluoride.

• Consult a dentist if you have sensitive teeth or gum issues.

• Discontinue use if any irritation occurs.

Where to Buy SP-8 Toothpaste

Given the uncertainty about branding and sourcing, it’s wise to choose platforms with clear return policies and reliable reviews.
