Questions

Can I use 'tonto' instead of 'zenzen'?

Yes, in negative sentences they have a similar meaning ('not at all'). However, this word is less common in modern slang and sounds slightly more traditional.

Does it always require a negative verb?

Usually, yes. The main exception is when used with verbs meaning 'to forget' (like wasureru), where it means 'completely'.

Is it considered polite language?

It is a neutral vocabulary word. It's not inherently impolite, but because of its conversational feel, it's better to use 'mattaku' in strict formal business settings.
