Hello and welcome!
Just a note, in addition to the advice that you have already received...
Dry food could be an option but it is definitely not the best one. It does not help prevent tooth decay or clean kitty's teeth.
Au contraire, dry food acts in quite the opposite manner by sticking to the teeth and gums causing irritation and dental damage.
Do not feed dry food for this reason. I know your vet told you to do this but veterinarians have very little education related to diet and nutrition. Most of their "education" is provided by pet food companies. Listen to your breeder.
The best way to keep his teeth in immaculate condition is with a raw diet. Even if you should not choose to go that route, small RAW bones, i.e. chicken wing tips or ribs, are an excellent option as they both scrape the teeth and exercise the jaw.
Good luck and enjoy your kitten.
Please post a picture so we can enjoy him too.
