Are Dentures Durable? How Long Do They Last?
The teeth on a denture are typically made from porcelain and resin. Traditionally, porcelain was the preferred choice, as it was stronger and more durable. In some cases, porcelain is still used as it feels similar to natural teeth. Also, the process used to harden the porcelain teeth makes them considerably harder, resulting in a more durable denture. The main disadvantage of porcelain dentures is that they are breakable if dropped, and they can wear down natural teeth if they bite against them. For these reasons, porcelain is more commonly used in full dentures as opposed to partial dentures.
Recently, acrylic resin has grown in popularity as the primary material in denture manufacturing. Acrylic adheres better to the denture base, it is easier to adjust, it weighs less, and it is significantly less expensive than porcelain. The disadvantage of teeth made from resin is that they wear faster than porcelain teeth, which causes changes in the way teeth make contact with one another. As a result, dentures made from acrylic need to be replaced every five to eight years; however, they are still much stronger than those previously made from plastics.
