How Adhesives Hold Dentures In Place


Posted on 8/23/2018 by Dr. Shiotsu
How Adhesives Hold Dentures In PlaceIf you have a properly fitted denture, a dental adhesive is not necessary. However, there are circumstances that can cause the denture to be loose even if it was initially fitted properly. The jawbone may shrink, making the device uncomfortable.

It is estimated that 50% of those with dentures may need adhesives to hold them in place. This is a more affordable option than going back to the dentist to get the device fitted properly. They come in various forms such as creams, pastes, and adhesive pads.

How does it Work?

Denture adhesive are made of materials that are designed to work in the moist environment of your mouth. Most adhesives react with saliva to form a paste like membrane that changes shape accordingly, ensuring that the dentures stick firmly to your gums. Most glues are made of ingredients such as sodium carboxymethylcellulose (CMC), Polyvinyl acetate (PVA), and Zinc.

The carbonyl groups are non-toxic, water soluble compounds that depend on the moisture in the mouth to provide the stickiness required. Zinc is another element common in these glues that enhance the device's capacity to adhere to the gums.

Types of Adhesives

There are three main types of adhesives you can choose from. They come in creams, strips, and powder form. Each of these options have their pros and cons. Creams are amongst the most popular denture adhesives. They are strong and reliable and can work on both dry and wet surfaces.

The main disadvantage is that they tend to ooze, making the wearer feel uncomfortable. Powders are considered to be more comfortable since they do not ooze or leave a mess like most creams. Strips or cushions are easier to apply. However, they are more costly compared to powders and creams.

Denture adhesives are a cost effective way to ensure that your dentures fit properly so that you can eat and speak comfortably. Contact us for more information on the available options for dentures and denture adhesives.
