In this ads of a brand of toothpaste, it says "... so you can bite into life without hesitation."
What does to bite into life mean here? Does it also have different meaning in different context?
I have searched in Oxford Advanced Learner's Dictionary. In the entry "life", I found the idiom "spring into life", which looks close, but I am not sure if they are related somehow or not. In the entry "bite", I cannot find anything rather than the literal meaning of "to bite into something".
