Secure Denture responds to questions on product ingredients:
My sincere thanks to Eileen Sheets from the Secure Denture customer service department. I wrote asking some questions about this zinc-free dental adhesive after learning about the health issues some people are reporting after using creams and powders containing zinc. I was given permission to include these questions and answers and am grateful that this company is willing to be as transparent as needed to assure customers of product safety.
While I don’t feel absolutely every concern was completely addressed, that may be my fault. I may have asked too many similar questions in one paragraph, ha. If you have additional questions about the Secure Denture product line, please email customer support at:

My email to Secure Denture Customer Service:
I found your website after my mom told me about a health alert on zinc-containing adhesives. However, the controversy over zinc has heightened my awareness that we really don’t know what the impact is of other ingredients in dental adhesives either. I’m writing to ask a few questions about the ingredients in Secure Denture and would like permission to post your response on my blog for others who might also have questions.
1. Your website states that Polyvinyl Acetate (PVA) inert, non-allergic and cannot be absorbed. If it is not absorbed, what happens to PVA that is swallowed in the course of wearing the denture? How does PVA exit the body and does it completely exit the body? In other words, is there a risk that polyvinyl acetate could build up in the colon or other organs or joints over time?
This is a good question. Most denture adhesives start to dissolve in the wet environment of the mouth. They dissolve and you wind up swallowing them. Secure is different in that it is non water soluble – waterproof. Most denture adhesives work by thickening the saliva and keeping the dentures in place by suction. Secure works by forming an actual bond with the gums. The poly vinyl acetate bonds to the gums, but can only do so if the gums are dry. The cellulose takes care of this by absorbing the saliva and keeping the gums dry. When the cellulose has absorbed all that it can (picture a sponge) the gums are no longer kept dry and the poly vinyl acetate cannot adhere, so the bond loosens. That is why it may take a bit of trial and error to determine the exact amount each individual should apply for the day. All of this explanation to help you understand that Secure does not dissolve in the mouth – and you don’t swallow it. When you remove the dentures, you remove the Secure.
2. Are the other ingredients, Miglyol and Sodium Carboxymethylcellulose,also non- allergic? Can they be absorbed in the body and, if so, are there any known issues with toxicity over time? Is there any risk that either of these can build-up in the joints or organs, to a point of toxicity?
There is always the possibility that a person may have sensitivity to the Miglyol (from glycerin) and the Sodium Carboxymethlcellulose (from trees). They are not inert like the poly vinyl acetate. However, we have found that an allergic reaction is quite rare. These ingredients will not be absorbed in the body because the whole product is non water soluble.
3. Is there any other ingredient, in trace or other amounts, in your product other than Miglyol, Sodium Carboxymethylcellulose and Polyvinyl Acetate?
There is a small amount of alcohol left over from the manufacturing process. It dissipates very quickly. Occasionally a person may find he feels a slight burning sensation upon putting the dentures in. This is from the alcohol. It passes immediately as the alcohol dissipates. Most people don’t experience this.
4. Are Secure Denture products available at any national chain, pharmacy or store or
is the only option for purchase to order them online?
Secure is sold in some health food stores and through some catalogs and many on line vendors. It is not sold in any national chain or pharmacies. A person can ask his local health food store to order Secure, it is carried by all the distributors and is easily available to the health food stores.
