Dentures are custom-fit dental prosthetics, so they offer a good fit in general. However, for an extra sense of security, dental adhesive can be used.
Denture adhesive is a non-toxic, water-soluble material that is used with dentures to enhance the normal physiological forces (adhesion) that hold the dentures in place. It is placed between the denture and the tissues of the mouth to reduce movement and slippage during eating and speaking.
Denture adhesive can be used with full or partial dentures, but not all denture wearers will need to use it. If the dentures will only be worn and used a fair amount and they have a good fit to start with, an adhesive may not be necessary. However, if you do a lot of speaking, singing, or will otherwise use your dentures more heavily than the average person, an adhesive may be beneficial in keeping the dentures in place and providing an extra sense of security.
Denture adhesives come in pastes, powders, and pads; the most common is the paste form. Always follow the label directions before use and be careful not to use too much. Excess adhesive can change the bite of the dentures and cause jaw problems that can lead to premature wear on the dentures themselves.
Pads are pre-cut shapes that are trimmed to fit the denture comfortably. Powders are simply mixed with water to activate and have the easiest cleanup when removing from the dentures.
If you are considering using a denture adhesive, be sure to consult with your dentist on whether it can be beneficial for you and, if so, which denture adhesive is best.
