Why is Grinding a Problem for Denture Wearers?

It’s all too common for people to assume that wearing dentures means not having to worry as much about their oral health. After all, there aren’t any natural teeth left to suffer chips, fractures, or decay. While that’s true, you still need to take care of your oral health, and you need to be particularly careful to avoid grinding.

When you still have your natural teeth, the main issue associated with grinding is a loss of enamel. That’s not an issue when you have dentures, but there are several other problems that can arise as a result of grinding.

Increased Bone Reabsorption

Probably the most serious problem associated with grinding your dentures is bone reabsorption. You see, your body will start to reabsorb the bones that used to support your natural teeth once those natural teeth have been lost. This is what causes the sunken appearance people often show when they have no teeth left. Bone reabsorption cannot be entirely prevented, but you can help reduce the speed at which bone is reabsorbed by avoiding grinding. When you grind, excessive pressure is placed on the gums, which often leads to a faster reabsorption process.

Alignment Problems

As you probably already know, dentures need to fit perfectly to avoid pressing too hard on any one part of the mouth. If they don’t fit properly, sores can develop, and you’ll find the plates slipping when you talk or eat. That’s clearly something you want to avoid, and you can do so by cutting out the grinding. If you’re constantly placing your dentures under pressure while sawing back and forth or side to side, you can easily cause alignment problems.


Alignment problems can be a pricey chore to fix, but they’re nothing compared to the cost and expense associated with breaking dentures completely. You probably won’t do any damage to the plates, but you could crack one or more of the false teeth. This isn’t just embarrassing and inconvenient – it can also be unsafe since broken false teeth are a choking hazard.
