>...the gaps between your teeth (is that what you meant by the grooves?)
No, the reference to grooves is on the crown of the tooth. (primarily molars) I think the issue with cleaning them out is that once solids get stuck in there and bacteria eat the solids they release acid that eats the tooth.
Years ago my dentist filled these grooves with a UV activated plastic sealant. I think this is standard practice now days. Not sure if a waterpik could do it, I've never had one. (If you have had one, has it prevented cavities for you?)
The best solution for cleaning those grooves is a dental hygience kit, which you can buy on ebay or amazon for around $10. The same stainless steel tools the dentist uses.
