I know how devastating it must be to you to lose your two front teeth. After all, they are the most prominent and visible of all your teeth. Nice front teeth can make or break your smile.
For most people the "flipper" (removable partial denture) is a temporary fix just to get your going so you don't have to face the world showing you're missing your two front teeth. However, believe it or not, a minority of patients are satisfied with their flipper and never get any other permanent replacement. However, the problems with flippers, as you might have realized already, is that they move around a little, the plastic teeth can break off the flipper, but they can also be uncomfortable and have spaces where food can collect under the plastic. I would recommend you see a more permanent alternative.
Speak with your dentist and he/she can go over other alternatives. You might consider two dental implants. Another choice is a fixed bridge. Both of those choices are considered more permanent solutions and are the preferred treatments when one is missing two front teeth.
If your dentist will make you a bridge, then you will probably have to wait at least six weeks after the teeth were extracted. This is because the area will take that long for the bone and gums to heal. If the dentist places a bridge before complete healing, you might find that the gum tissue continues to change and there may result in a space under your fixed bridge that looks less than ideal and also collects food. Best to wear the flipper until the complete healing has occurred.
If you can do implants you will need to have a consult with an implantologist. He will need to determine if you have enough bone and whether or not he has to graft tissue or do bone augmentation prior to the implant placement. Then after the implants are done your dentist can place crowns over the top of the implants. Implants are going to cost you more and may take months to complete the treatment, but probably the overall best way to go.
Good luck,
