I prefer to have all 30 teeth pulled, could i do that?

Personally, no: But if your teeth are that bad, then see a local dentist for a consultation. Consider your options carefully.. you won't grow a new set and to replace all of your teeth with implants and crowns will cost more that restoring your own.

Very sad : Your teeth are important for your dental and general health. They help you chew, swallow, speak, and smile. The reason a lot of people end up getting dentures at such a young age is due to not having the money for conservative dental treatment. I would really advise against having your teeth extracted. Not because it's painful procedure, but because of the long term implications on your life.
