I suggest you use interdental brushes….pipe cleaner things with a handle, Wakerpiks are very rarely useful. You are trying to achieve the same effect in between your teeth as you do with a brush on the easier to reach surfaces. So why try anything other than a brush?
The purpose is to disrupt the biofilm. Mechanical means win hands down. Which is why mouthwash is minimally effective. Yes there is some circumstances where we may suggest an antiseptic oral rinse…. Chlorhexidine for example. But it is not a substitute for effective mechanical cleaning. Oh and listerine has some evidence, but less than CHX. If you have ++++ decay a fluoride rinse at a different time to when you brush may be helpful.
A dentist. And yes I ride a Santa Cruz.
