Piksters clean the spaces between your teeth where a regular toothbrush struggles to reach.
Piksters can be used one-handed, the cap can be used to extend the handle which also makes them easier to manipulate than floss and they are reusable (rinse between use)
Choose a size that inserts without force. The correct size will fit easily.
Front teeth do not require the brush head to be bent. Insert the brush head in line with the plastic handle, slowly with a gentle twist or wriggling action.
Access to back teeth will generally be easier if the brush head is bent over. Use one finger to push the tip of the brush head (not the base) over to an angle of approximately 45 degrees to 90 degrees. Pushing the tip will avoid a sharp bend where the wire meets the plastic handle, and reduce the stress concentration and likelihood of breakage in the metal.
If the wire buckles, discard the brush. Once buckled, it cannot be straightened properly
