Okay, so, I've been researching walruses to make sure I'm

No. Walrus tusks are modified teeth. If they break their tusk it won't grow back.

From what I read, it's a little of column A and column B.

If they outright loose a tusk at the root, that's it, shit's gone forever.

On the other hand, if it's just partially broken, it'll continue to grow from the root as normal. The end will still be fucked up of course, since tusks, like hair, grow from the root.

That doesn't mean the tooth is growing back. If a juvenile walrus breaks a tooth, it will continue to grow to its adult size. If an adult breaks a tooth nothing happens.

Again, not quite.

A female walrus is sexually mature at 4-6, while a male walrus is good to go around 7 or so.

However, tusks continue to grow until 15 (which, not so coincidentally, is the age males typically get to start mating, as tusks are literally the e-penis of the walrus world.) The average walrus lifespan is 30 years, so tusks continue to grow well past adulthood.
