As with anything else, dentures can break. They can snap in half, crack, teeth can break off, etc. Dentures undergo tremendous flexion and bending when chewing and biting. Over time, this creates micro stress lines all through the acrylic that eventually accumulate to the point where the acrylic gives out. Luckily, we can fix them.
While some repairs are simple, others are complex and although we can usually repair them back to the way they were, we can’t always fix the reason why they break. That’s when consideration is given to relines, rebases or new dentures. Never use crazy glue to fix it yourself. This is toxic and may cause more issues than you need.
