Dentures are removable false teeth designed to replace missing teeth, including complete(full) dentures and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.

Someone may concern whether dentures will make them look different. Actually, dentures are made to closely match your natural teeth, so the change in appearance after wearing dentures will be not very noticeable. What's more, they may even improve your smile. 

When it comes to eating and speaking, it will take you a little practice to get used to dentures. After wearing dentures, it's possible for you to have difficulty in pronouncing certain words. If so, just practice more by saying the words out loud. Practice makes perfect. With practice and time, you will pronounce properly with dentures. With regards to cleaning dentures, you need to brush them on a daily basis, just similar to your natural teeth.
