Dentures are removable dental appliances that are used to replace missing teeth and surrounding tissue. They are typically made from a combination of acrylic resin, metal, and/or porcelain, and are custom-made to fit the patient's mouth.

There are two main types of dentures:

1. Complete dentures: Complete dentures are used when all of the natural teeth are missing. They are designed to fit over the gums and palate, and are typically held in place by suction or denture adhesive.

2. Partial dentures: Partial dentures are used when some natural teeth are still present. They are designed to fit around the remaining teeth and are typically held in place with clasps or other connectors.

   Dentures can provide several benefits, including:

   1. Improved appearance: Dentures can help to improve the appearance of the smile and the overall facial structure.

   2. Improved speech: Dentures can help to improve speech by filling in gaps and restoring missing teeth.

   3. Improved chewing ability: Dentures can restore the ability to chew properly, allowing for better digestion and overall health.

   Proper care and maintenance of dentures is important to ensure their longevity and effectiveness. This includes regular cleaning, soaking in denture cleansers, and avoiding hard or sticky foods that could damage the dentures. It is also important to schedule regular check-ups with the dentist to ensure that the dentures are fitting properly and to address any potential issues.
