Invisalign is the modern way to achieve straight teeth and this nifty little tool is only getting better!
In the old days if you wanted your teeth straightened, you went to your orthodontist and had something that looked like a mid-evil torture device placed on your teeth. You then had to return to the Orthodontist regularly to get your wire braced tightened every so often (again like a mid-evil torture device!!!) until your teeth moved into the correct position.
Welcome the dawn of the golden age of orthodontics!
