Probably Not. Both of those procedures are considered "cosmetic" and "optional, " so they will rarely be covered. I've personally never seen coverage for these types of procedures. There may be a very high-end dental plan out there somewhere, but the monthly premiums would cost much more than just paying for these services yourself. Improving your smile is a great investment which you won't regret.
Very few. Most insurances do not cover cosmetic procedures. There are very few that do. You can have your dental office preautherize the procedures first.
