What Causes Broken Dentures

Dentures should last anywhere between seven and ten years when properly maintained and cared for. A set of high-quality dentures is an investment, and it can be upsetting when they become damaged or broken. Damage can occur for a variety of reasons, from general wear and tear to accidents. By understanding how dentures can become damaged or broken and taking steps to repair or replace them, you can get the most value from your investment.

General Wear and Tear

Daily wear and general use of your dentures can cause small fractures in your dental appliance, that may slowly grow into substantial cracks or breaks. Because your dentures are being used every day in place of your teeth, it makes sense that they would wear down over time. The “gums” portion of the dentures are often made of acrylic, which can weaken and break over time. Keeping your dentures clean and maintaining them daily can help prevent breakage.

Dropping Dentures

Accidents happen, and one of the more common reasons for denture breakage is dropping them into the sink, on the counter, or onto the floor. When your dentures aren’t in use, you can safeguard them from accidental breakage by keeping them in a protective case.


An improper fit can also cause damage to your dentures. If the fit is too loose, the teeth won’t line up correctly when you bite and can cause your dentures to break. If the fit is too tight, undue pressure can result in cracks. To prevent long-term damage, notify your denturist about issues with improper fit or a misaligned bite.

Can My Dentures Be Repaired?

Depending on the extent of the damage, broken dentures may be repaired by a denturist:
  • Acrylic “gums” portion can be repaired by reinforcing the fracture with a metal mesh overlaid with new acrylic.
  • Full fractures may be repaired but usually only if the repair is a clean break.
  • Dentures with multiple fractures may be challenging to repair, but the separate pieces may be rebased and relined in a laboratory if the damage is not too severe.
