Treatment has made my gums more sensitive. At first I was using a Biotene toothbrush. At first they were great, but now they feel too soft. Also, I'm down to my last one and I notice they are not made anymore. I was also using RX Ultra Suave toothbrushes from PHB which are made specifically for post-treatment. I was using the red one, which is the softest. I still have a few of these, but I no longer need one this soft. I thought of trying one of their firmer ones, but I'm tired of their small size.

Next I tried Dr. Collins Perio, which feels too rough. I've also tried ultra soft brushes from Gum, Preserve, and Oral B, but these are too stiff.

Any recommendations?
