The main disadvantage of removable dentures is that they can be uncomfortable and may require frequent adjustments by a dentist or dental laboratory to fit properly. They can also cause problems with speaking, eating, and taste perception. Additionally, dentures can cause irritation, sores, and infections due to the lack of natural suction the denture has from not being permanently in the mouth. Finally, removable dentures can cause the underlying jawbones to atrophy over time, reducing a person’s bite strength and changing the look of their face.
