Whether it be a complete denture, a partial one or even a temporary one—many, many, MANY people are wearing a removable dental plate in some form.
It’s also common, (especially when they are in the place of front teeth) to be self-conscious without them in. This is completely understandable, however if your plate is left in all the time it can be like going to bed with your shoes on… and nasty fungal infections can start to grow underneath!
To prevent this, all you need do is give your gums a break. Ideally it’s good to leave your plate out at night (in water to prevent drying out). If you don’t like doing this, you can at least take them out while in the shower and give your gums a rinse.
