Dentures are probably one of the least appreciated medical prosthetic devices. If a person has a leg replaced, most reasonable people understand that learning to walk again will take a lot of practice. Until recently, hand prosthetics have been able to do much more than simply grab something, and most did nothing more than look like a hand.
Unfortunately, many first-time denture wearers do not realize how different a denture is from natural teeth.
Many patients go out with their new set of dentures and try to eat a steak. Due to inexperience, they are quickly frustrated by their limited chewing ability. Other new denture users are afraid to be in public as they notice their dentures shift around slightly when they talk. These patients haven't learned how to control their dentures and not "play" with them in their mouths.
The easiest way to control and adapt to the denture is through implant placement which can help make the denture more like natural teeth. For people without implants, learning to use a denture is like learning to walk. The three aspects of walking are the bones that support you, the muscles that produce forces, and the brain, which coordinates everything.
The bones form the ridge for dentures, which supports the denture and allows it to sit in one spot where it fits the best. The mouth's muscles (the tongue, cheeks, lips, and chewing muscles) produce forces and pressure to keep the denture on the bone.
Finally, the brain tells the muscles which ways to react to the denture, so it stays in the right place depending on whether the wearer is eating, talking, sneezing, or doing nothing.
