I think it's great that your lower teeth are fairly straight already. As for the top, I would agree that bonding is not really a good option because composite fillings are basically "plastic" and chip easily. You will also notice that the surface of the bonding will begin to wear after a few years and you will begin to see the where the bondings ends.Based on your smile line, 6-8 Porcelain Veneers would probably be a good idea because they are much more durable, basically don't wear, don't stain, and have margins that are nearly invisible. Your treating dentist will have to determine how many teeth you will need to treat in order to have the best result. Treating 4 teeth is possible, but will leave you with canines that don't match your front teeth in both shape and color. For that reason, I would recommend at least 6, but up to 8 in order to get a harmonious "look" and color for all teeth that are visible when you smile. Do keep in mind however that Veneers are an irreversible procedure, as we have to remove some tooth structure from the cheek-surfaces and biting surfaces of the teeth in order to make room for our material. However, compared to the reduction necessary for a crown, it is very minimal. For a crown, up to 60% of the visible part of a tooth needs to be removed. For this reason, I would try to avoid a crown unless absolutely necessary.As for insurance, I think you can probably expect no coverage. While many insurances have contracted rates for dental work with participating dentists, every insurance that I know of WILL NOT cover veneers unless the dentist can prove that you "need" a veneer a treat a specific dental problem (ie. large chips). I think it would be a stretch for most insurances to cover this case as it appears to be a "cosmetic" procedure, which is something insurances don't cover. Please ask your dentist and confirm that insurance will indeed cover this procedure.After having said all that, I would say this: Don't shortchange yourself by choosing a lesser less-esthetic option. Save up what you need and go for the Veneers, as the esthetic result is superior. You deserve to have a great and long-lasting smile
