Interdental brush can only be used if there is distance/spacing between teeth and/or gum. For example, teeth with spacing or teeth with gum recession due to gum disease.

It is also suitable for those undergoing orthodontic treatment and for crown and/or bridge cases.

Tooth Picks

It is made of disposable soft wood or disposable soft plastic for interdental cleaning. It is usually used after meal.

Tooth picks should only be used when there is spacing between teeth / due to gum recession (gum disease). It is not suitable for use in children.

Avoid using tooth picks for normal teeth (when there is no spacing between teeth) as it may cause gum injury. If this is done repeatedly over a long period of time, the gum might be pushed down from the normal gum level thus creating space between teeth.

  • Choose the right interdental cleaning kit according to your needs or as advised by the dentist as it is crucial for optimal oral health. Please refer to your dentist for advice.
