About this item

  • Advanced Niacinamide Whitening Formula:SmileShark Niacinamide Whitening Toothpaste has a carefully developed formula combining multiple active ingredients to promote brighter teeth and a healthier mouth. Niacinamide reduces the appearance of surface discolouration, while hydrated silica and sodium bicarbonate gently polish away build-up and maintain a balanced oral environment. Stabilising agents ensure a smooth texture and effective delivery, while peppermint extract provides long-lasting freshness.
  • Gentle on Dental Enamel, Tough on Stains:Formulated with niacinamide, SmileShark whitening toothpaste helps to visibly brighten teeth by gently lifting surface stains caused by coffee, tea, wine and smoking. Containing effective cleansing and polishing agents, it targets discolouration while supporting enamel health. Its low-abrasion formula removes plaque and build-up without causing sensitivity, making it ideal for daily use — even for those with sensitive teeth.
  • Daily Oral Health Protection:Unlike abrasive or peroxide-based formulas, our niacinamide toothpaste offers a gentle, low-irritation solution for daily teeth whitening, making it ideal for adults seeking a naturally brighter smile. More than just a whitening product, SmileShark supports comprehensive oral health by reducing bad breath, minimising plaque build-up and promoting gum health. It is mild and effective for twice-daily use, making it a reliable choice for those prioritising both appearance and oral care.
  • Gentle, Effective, and Consistent Oral Care: SmileShark toothpaste has a low-abrasion formula containing cleansing agents such as hydrated silica and baking soda, which polish your teeth without damaging the enamel. Stabilised with xanthan and cellulose gums, it provides a smooth texture and consistent performance, supporting overall oral health and ensuring your daily routine is both comfortable and effective.
  • 2-Pack Value for Long-Lasting Use: This convenient pack contains two full-size 100 g tubes, offering excellent value and long-lasting use for your daily oral care routine. Whether you're at home or out and about, this set ensures you always have reliable teeth-whitening and breath-freshening support to hand.
