Yahoo! Canada Answers - About Lumineers?

I thought Lumineers were like ceramics for your teeth?
Ceramics are recommended for people with dead teeth, so dentists can drill in, and over 35*.

I don't want braces either (and I'm 15, small world) but there are invisible braces called Invisaligned, claimed to realign teeth in about a year. Since your teeth are almost straight and you have a little overbite that you don't mind, I think the realignment process should take less than 9 months. Invisalign is very comfortable and very successful.

Here are some things from Invisalign.com:

A certified Invisalign provider will create your individual treatment plan using Invisalign’s clear, custom-molded aligners to solve a range of issues, including:
~Overly crowded teeth
~Widely spaced teeth
~Overbites
~Underbites
~Crossbites

With Invisalign, you can:
~Be as active as you like because Invisalign won’t hold you back
~Remove your aligners for special events, eating and brushing
~Feel more confident everywhere you go

~Unobtrusive in business meetings or social gatherings
~No metal wires or bands to irritate your mouth
~Many people won’t notice you’re wearing aligners

Now as for the whitening, I think that'd be a different story but it could all be done at one place.

*my guess of when teeth stop growing and are able to be cut and drilled into for ceramics.
