ToothPik are a new eco friendly interdental brush. There are only two sizes in the ToothPik range: Small and Large

The Small size is a good size to start with if you have used interdental brushes before. It is a size that fits between most peoples teeth over the age of 35.

The Large size will be suitable for many older patients or patients how have had gum problems in the past. If you have used interdental brushes in the past and found they pass easily between your teeth and feel loose, you may want to try the Large ToothPik and see if it fits more snugly between the teeth.
