Why I (50 yrs old) get braces or proctodontic trainer than a complete overhall of my incisors including excision of 2 of them?

I visited a nearby dentist for correcting my edge-to-edge incisors. The dentist who examined my teeth took panoramic x-ray several times. He has then told me that correcting it would entail exteacting 1-2 of my teeth, shortening the rest of incisors up to half of their height and then bringing them up to a desired height and direction. I am not convinced of all these operations; Why can't I be treated like any other customer for cosmetic reasons using proctodontic appliances? I need your advise.
