Broken Bottom Dentures & How to Fix Them

Dentures play a crucial role in restoring a person’s smile and ability to eat comfortably. However, like any other dental appliance, they can sometimes break or become damaged. When it comes to lower dentures, in particular, their constant movement during chewing and speaking can increase the likelihood of damage. In this blog, we will explore the common causes of broken bottom dentures and guide how to fix them.

Common Causes of Broken Bottom Dentures

Accidental Dropping: Accidents happen, and dropping your dentures on a hard surface can result in cracks or fractures, especially if they land at an awkward angle.

Wear and Tear – Over time, dentures can wear down due to daily use. The constant pressure from chewing can weaken the denture material, leading to cracks or breakage.

Poor Fit – Ill-fitting dentures can place excessive stress on specific areas, making them more susceptible to damage. This is why regular check-ups with your dentist are essential.

Chewing Hard Foods – Chewing on hard or crunchy foods can strain dentures, potentially leading to cracks or fractures, especially in the lower dentures.

Ageing Dentures – Dentures are not designed to last forever. As they age, the materials can become brittle, increasing the risk of breakage.
