QUESTIONS, ANSWERED
Good to know before you brush.
Clear answers based on the supplied SP-8 product specification. For individual dental concerns, ask your dental professional.
Ask us a question →What is the SP-8 Enzyme-Mineral Clean System?
It is our name for the combination of papain with a calcium carbonate and hydrated silica cleaning base. The formula is positioned for everyday surface cleansing and a cleaner-looking smile.
How does SP-8 help with a brighter-looking smile?
Regular brushing helps clean everyday surface buildup and visible staining from food and drinks. SP-8 is not a bleaching treatment, and cosmetic appearance results vary.
Is SP-8 fluoride-free?
Yes. The supplied formula specification does not list a fluoride ingredient. Always review the package you receive for the final ingredient declaration.
Is SP-8 SLS-free?
No. The supplied ingredient specification lists Sodium Lauryl Sulfate (SLS). We disclose this clearly so you can choose a formula that fits your preferences.
How often should I use it?
Use a pea-sized amount and brush gently for two minutes, morning and evening, or follow the advice of your dental professional. Spit out after brushing and do not swallow.
Who is SP-8 intended for?
Our current product information positions SP-8 for adult oral care. Keep it out of reach of children.
Can I use it with sensitive teeth, fillings, or crowns?
Individual dental needs differ. The supplied materials do not establish a sensitivity-treatment or dental-restoration claim, so ask your dental professional before use if you have sensitivity, ongoing treatment, fillings, crowns, or other concerns.
What should I do if irritation occurs?
Stop using the product and consult a dental professional. For product or order questions, contact support@ShopYayashi.com.
