Hi Holly, There really isn’t any set time of how many hours to keep your denture in. Some people wear them 24/7 if they’re comfortable. But most have the denture in place all day and then take out for bedtime. That’s also a convenient time to clean the denture in a solution overnight.
The more you wear the denture the more comfortable and confident you’ll feel about wearing and handling it.

There are quite a few different denture cleaners on the market. Brand name soaks are safe for your denture and do a great job of removing food, plaque, stains and odors from the denture. There are also special denture brushes that can make cleaning easier as well. Experiment! You’re not going to hurt the denture. You will want to avoid anything that’s heavily abrasive such as whitening tooth pastes. So stick with the soaks and toothpaste that’s made for dentures. Though in a pinch you can use a regular toothpaste. Just remember to place water in your sink to cushion the impact if the denture slips from your hand while cleaning.

Cleaning the denture and the products you’ll use are a personal choice just like your toothpaste and floss. We each gravitate to what works best to clean/whiten our teeth, what gives us a ‘good mouth’ feel and freshens breath. So I’m expecting you’ll try your options too and find a favorite.

I found a couple of sites that might be useful for you for cleaning your denture and also for learning a little more about certain types of cleaners.

Like I said, experiment to find what works best for your needs.

Enjoy your first real rinse today! That’ll feel good…like taking a long awaited shower! 😉
