Dental Professionals: How to Properly Size TePe Interdental Brushes for Patients

The great thing about the TePe interdental line is how extensive it is. You really can tailor patient education for cleaning interdental spaces to exactly what the patient needs. However, getting started with the TePe line can be overwhelming. Especially, if you have been using only 1, 2 or 3 sizes for interdental cleaners. 

We hate wasting product as we try to size our patients, so here is a helpful tip for sizing TePe's interdental brushes. I take my probe, the one I already have on my tray, and use it as my sizing tool. The probe is slightly bigger than the wire of the blue brush. I insert the probe as I would an interdental brush:

  • If the probe rubs the sides of the teeth, I would size blue or down.
  • If the probe doesn’t even fit through the embrasure space, then you are looking at a pink or orange for that space.
  • If the probe goes through the embrasure space and does not touch the sides of the teeth and the tissue allows, I would try a yellow TePe brush.
  • As the embrasure space increases to a class 2 or 3, you will find the green, purple, grey or black will work great!

Don’t be afraid of those larger brushes. You want the brush to be snug so that the bristles collapse as they enter the embrasure space, branch out into the curvy areas of the tooth, and then exit fully on the lingual aspect to help clean that lingual line angle. As long as the wire is not rubbing the sides of the teeth, try the bigger sizes. If you feel that the wire is rubbing or the tissue fills the embrasure space, then size down.

Good luck and if you have any questions, don’t hesitate to email me or leave a comment below!

    It would be great to see an environmentally friendly version of these brushes. Bamboo maybe. Are there plans to introduce these? Many thanks from a TePe user.

    “Reaching the back teeth is often hard for most patients. The pink interdental brush is a great option but if it is bending, I would suggest trying the pink ANGLE interdental brush. This puts the wire at 90degrees and helps to eliminate the struggle with the cheek to reach those very back teeth” (Michelle Strange)

    I just received my first order of interdental brushes. I got the size .4mm brushes and the size 0 angle brush. I also got the easypick. They work great but I can’t get them to reach between my back molars. I have tried and the wire just gets bent out of shape. My dentist has said that I have a small mouth. I have had fillings in these back molars so I need something good to floss them. I can get my toothbrush on them with no problem, but i need something to floss them. Can you help please ?
