This very much depends.  If the roots are periodontally healthy and you
have enough clinical crown structure (above the gumline) to work with
the prefered route would be crowns.  This can be difficult in situations
such as yours, where the accelerated wear in DI means that besides the
teeth often being worn down to the gumline, this also means that your
jaws have to come closer together in order for your teeth to meet.
    Ideally, a prosthodontist would put you in some kind of interim
appliance--possibly utilizing some kind of bite plate to gradually open
your bite so that crowns of normal dimension could be placed on your
teeth and a normal bite reconstructed.  This is a lot of work, usually
done over a significant length of time.
    Dentures and implants may be options as well, but I would very much
hate to go the denture route in one so young.  It may in fact require a
flexible approach, possibly involving crowns, implants, and perhaps
removable devices as well.  But I'd avoid dentures if at all possible.
