Acrylic partial dentures consist of replacement teeth that are set in pink or gum coloured acrylic resin. To aid the retention of the denture one or more wire clasps are placed around the natural teeth in the mouth. If some of the remaining natural teeth need to be extracted at a later date additional false teeth can be added to an acrylic partial denture. This type of partial denture is much quicker to make than its metal counterpart. But whilst this is also the least expensive type of partial denture there are some disadvantages: Acrylic partial dentures are quite brittle so can break The acrylic is usually made quite thick to try and prevent breakage but many wearers say it takes time to get used to The false teeth have a tendency to sink below their original level as the gums resorb. When this happens wearers have to get them relined fairly frequently, or occasionally have them reset. This then makes what was the least expensive choice quite a costly one Acrylic partial dentures are still a very popular choice for many denture wearers and depending on the use and care of the denture how long it will last can vary from one individual to another.
