Porcelain Veneers for Lost Enamel? Other Options for Front Teeth?

The only less expensive option is bonding. It won't last as long, but it can still look good. Porcelain veneers aren't likely to last a lifetime on a 19 year old either.

Porcelain veneers are very beautiful and lifelike, however when finances are a concern you have to consider other alternatives.  Direct resin bonding can be very pleasing esthetically as well when done by an artistic dentist.  There are new resin filling materials available today that when placed carefully can look very beautiful. 

It's true that bonded restorations can discolour with time, and will most likely need replacing sooner than veneers but they can still last for a number of years.  If your daughter is self-concious about her smile, and you can't afford porcelain veneers at this time, perhaps regular bonding would be a good choice, knowing that down the road you always have the option of upgrading to porcelain.

The other thing to consider is the reason for the loss of enamel.  Is it acid erosion, heredity, traumatic injury (caused by some sort of accident).  Also does it involve just the front 2 teeth or is it more teeth than that.

Good luck.

But also less durable. Veneers are the BEST treatment and will last a long time..bonding is second best and will need to be replaced periodically. Try getting CareCredit and do a financing plan at 0%

Bonding generally is not a good option as it is not as durable and rarely as esthetic.  While the fees may sound high, they are cheaper in the long run.

If the enamel is lost due to genetics, full crowns might be needed as the tooth structure itself bonds differently than normal.

An experienced cosmetic dentist can help you decide, but the options truly are limited.
