Dentures, like natural teeth, are subject to wear and tear over time. The pink acrylic part of dentures is the most vulnerable to damage, as it weakens and becomes more flexible when chewed, leading to cracks or total rupture. Hard foods such as nuts or hard candies can also chip or break the artificial teeth used in dentures. Chips in the acrylic base of the denture can also occur due to the same reasons.
As dentures get older, they become more likely to break due to a loose fit. Repetitive bending weakens the plastic and causes it to break, or can cause the teeth embedded in the base of the denture to loosen and break. To prevent dentures from breaking, it is important to have them put back on when they come loose, or replace them after 5 years. Additionally, it is important to be aware of how much pressure is applied when using dentures, as excessive pressure can cause a break.
Progressive bone loss can also cause dentures to become loose, leading to tension and pressure points that can cause the denture to crack or break. Finally, accidental or incidental breakage is also a common cause of broken dentures. If your dentures do break, it is important not to try and repair them yourself with superglue or store-bought repair kits. Instead, take the pieces separated to your dentist for examination and possible repair in a lab.
If there is significant damage to the base or your entire denture is broken, the repair may be more complicated. Studies show that dentures may not break instantly when they fall; however, the impact can weaken an area and cause the denture to break up to 6 months later.
