While dentures are quite durable, they are vulnerable to breakage if they are dropped. Therefore, when you take them out of your mouth, you should do so above a soft surface, such as a sink full of water or a folded towel.
Also, you should avoid extremely hard foods that might break your dentures. For example, you should never bite hard cardies or ice. If you decide to eat somewhat hard foods, such as raw vegetables, that is fine. However, do not bite down on them with your dentures’ front teeth. Instead, cut the food into small pieces before you eat it. Then, distribute it evenly on both sides of your mouth while you chew.
