Will it

depends on how wide your vag is naturally, the size of the tampon, etc. so sometimes yes, sometimes no.

It may not break it all at once, but after using them for a while it could easily totally wear away.

If you are worried about it causing you pain or extra bleeding I don't think that is something you need to worry about.

If you are worried that you need to have your hymen intact later to prove you are a virgin or for some symbolic reason then you should stop worrying. Tampons are just one of the things that can cause you to lose the hymen, some girls can lose them just through strenuous exercize. A lot of people know this nowadays, and if a future boyfriend was not aware of these facts you can have him look them up.

Protecting the hymen is not necessary but you may not want to use a tampon for other reasons. They are likely to cause more dryness down there than is healthy and this can lead to mild infections such as a yeast infection. Also, wearing one for too long can give bacteria a chance to grown and make you succeptible to toxic shock syndrome. Though this is rare and takes wearing one for more than a full day to occur.

Toxic shock syndrome can occur from less than a day of wearing a tampon.

yes it will. whore.
