Dentist recommended 4 dental crowns after Invisalign. Is this the best approach? (Photo)

I just finished invisalign to improve my smile. During treatment, the front laterals were pushed out to create spacing with the intent to use bonding to bulk them up. They are now recommending 4 crowns instead as the teeth have multiple fillings and to better match color. It looks like there’s still 70% of the original tooth after fillings. I’m only 28, so I’m hesitant to undergo something so invasive. Would 3/4 crowns, veneers or bonding be better if the primary goal is cosmetic?
