Thrush is a yeast infection that shows up as a coating on your tongue.
There is no definitive answer to this question as it can depend on a number of individual factors.
It is generally agreed that dentures can contribute to the development of thrush, especially if they are not cleaned properly or fit poorly. They can provide a perfect environment for the growth of yeast, which can then lead to a thrush infection.
If you wear dentures and develop thrush, it is important to see your dentist so that they can determine whether your dentures are the cause and advise you on the best way to treat the infection.
