Since my last dental appointment (3 months ago), I’ve cleaned one half of my mouth with a water pick (in addition to brushing on both sides), with the goal of determining if it actually did anything useful. I was inspired by my dentist’s insistence that I Do Something despite not noticing when I consistently used the pick. I pre-registered on Facebook that if the hygienist spontaneously commented that one side looked better, or some objective measure like # of cavities was different, I would consider it evidence in favor of the water pick. Today was the appointment.
Final results:
- Hygienist didn’t comment either way.
- No new cavities on either side
- Gum pocket measurements were worse on the water picked side.
Obviously one trial isn’t conclusive, but I’m giving up on the water pick. Next step: test flossing.
