Invisalign is often the perfect approach to the very problem that you are describing. The latest Invisalign attachment designs can move the teeth in such a way as to close gaps not only at the chewing edges of the teeth, but at the gumline as well. Sometimes a little smoothing of the sides of the teeth is necessary to make this happen, and sometimes adding a little bit of composite material, called bonding, helps too!

I am assuming your Lumineers were bonded on. SO...agressively brush and floss these, just as you do all of your teeth. Marcus Whitmore, DDS Dallas, TX
Sorry, but it is not possible to tooth structure to "grow back". You basically have two good options: 1. continue with orthodontics, either traditional braces or clear aligners or 2. Have your teeth restored with either composite or porcelain It is truly unfortunate that you had this bad experience, but you do have good options. Marcus Whitmore, DDS Dallas, TX
We routinely use mini dental implants for the support of removable prostethics like dentures. The small size and versatile placement is a real advantage for holding onto dentures. For non removable teeth, like crowns or bridges, mini implants don't provide enough support, and therefore are not recommended. Mini implants are not designed to provide the strength for a "fixed" tooth like a crown, and would likely break off if used for that purpose.
Bonded false teeth in the front of the smile can be a very long lasting solution to missing front teeth. If the bonding is sufficient, and the teeth are cleaned routinely, both daily and by a dental hygienist, it should be quite a nice way to go. Problems that shorten the life of these fixes are bad bites which cause trauma to the bonding, or buildup of plaque and tartar which contributes to decay around the teeth or swelling and bleeding of the gums, both will cause a shorter life span.
