Conair 12168 Compact 8-Tuft Brush Head (2-Pack)

The product does not work. When you turn on the tooth brush the brush head twists off. This is bad design for the product. It starts to brush, the brushes move, but the brush head twists off the toothbrush with the vibration of the toothbrush.

Very hard to find (obsolete item), works best of any electric toothbrush head I've used, great for crooked or crowded teeth especially

I have been using Interplak toothbrushes for years, but somehow was unable to purchase replacements until recently. This new brush head design is far superior to those in the past. This is the absolute best toothbrush you could use!

It's very confusing to find the right Interplak Replacement Brush Heads to fit an Interplak toothbrush. I have previously bought the Model 12168 brushes and they fit my Interplak Toothbrush Model DPI-6; this is the one with a removable battery module that directly plugs into (DPI) an electric outlet. But the packaging only references it fitting the Interplak toothbrushes Models 12209 and NT8. Unfortunately, the DPI-6 is no longer available, but it's well worth continuing to buy brush heads for it and the other models because it is a very good and effective design. I've used it and its predecessors for a very long time, back to when it was first introduced way before the brand name changed to Interplak.
