Boots Expert Dental Expanding Whitening Floss

  • Expands between the teeth giving a more thorough clean
  • Helps your teeth retain their natural whiteness

Combines both tartar control and cleaning agents, and will help retain the natural whiteness of your teeth. It can be difficult to clean in between your teeth so our floss is designed to expand between different interdental gap sizes, to give a softer yet effective clean. Waxed to aid the movement of the floss, helping to clean and control tartar. Formulated with Sodium Bicarbonate (Baking Soda) to help remove unwanted stains and deposits. With an add minty flavour to provide a fresh mouth feeling.

How to use

Break off around 40cm of floss.

Wind around the middles fingers of both hands, leaving 8-10cm in between.

Gently guide the floss between your teeth and run carefully up and down exerting pressure on each side of the tooth.

Floss to just below the gum line and use a clean section of floss each time.

It is common for your gums to bleed when you first start to floss. If it continues you may need have early signs of gum disease and should consult your dentist.

Remember to visit your dentist every 6 months.
