I previously had some gum disease which resulted in a small amount of bone loss on my back two teeth, according to my private dentist when he took routine x-rays. My gums are pink and healthy now and I use an electric toothbrush. However I noticed a long time ago that two of my upper front teeth had receded a bit and my tooth arent perfectly straight either (despite having braces when I was 15). I would really like to have a perfect smile. Would invisalign work (my teeth are otherwise white and healthy, no fillings) or would that make the receding gums worse? would lumineers be a better option?
