False Teeth - Usefulness of Denture Adhesives

Denture adhesives enhance the retentive interface between the surface of a denture and the underlying tissues upon which false teeth rest.

Optimizing the Interface Space

There is a slight space at the interface between the inside of a denture and the jaw that is usually filled with saliva. As this gap increases, a denture becomes less retentive and stable.

The interface space arises because of material and fabrication limitations used in making a denture. This gap also is contributed to by the constant changing contour and shrinkage of jawbone.

While an interface space exists in all dentures and increases with time, optimum denture function and retention depends upon reducing it. Denture adhesives fill this increasing space, improve suction, and create a sticky contact between a denture and underlying surfaces. This also helps resist foods from collecting under the denture base.

How to Use Denture Adhesives

Thin paste adhesives are preferred to powders since they are already fluid and easier to manage and apply. However, some prefer powder types. Whatever works best for an individual should be used.

Pea-sized amounts of the paste may be placed in a few places within a denture where jaw ridges fit and where the roof of the mouth contacts. A thin film of adhesive spreads out as a denture seats in the mouth. Use the least amount to do the "job."

If excess amounts are necessary, then the opinion of a dentist should be sought since denture maintenance may be necessary. A licensed dentist should be routinely seen at six-month intervals for routine oral examinations and bite adjustments.

A person needs to experiment with how often to apply adhesives. Some apply it before meals while others function satisfactorily all day with one application.

A denture and mouth should be cleaned of all adhesives at least once a day, and the denture should be left out of a cleaned and rinsed mouth for at least an hour a day.

How to Clean Up Your Dentures

It can be difficult removing adhesives. The denture may be cleaned with a brush, soap, and running water, or with a little white distilled vinegar in water.

All adhesives should be removed from the mouth for hygienic purposes. Rinsing with extremely warm water or salt water helps removal. It may be necessary to use a soft toothbrush or wash cloth-like material to assist removal from the mouth tissues.

Advantages of Denture Adhesives

• Effectively fills the interface gap between a denture and underlying jaw.
• Provides a sense of security with wearing dentures, even with well-fitting dentures when additional confidence is desired.
• Facilitates acceptability and builds confidence with wearing new dentures.
• Reduces food impaction beneath dentures by closing prosthesis borders.
• Helps an individual open their mouth wider for more confident chewing (increases the chewing stroke), rather than eating with small strokes to compensate for concerns about the potential for a denture coming loose.
• Decreases the irritation and chafing of mouth tissues from habits such as grinding teeth together (parafunctional activities).
• Facilitates wearing dentures for individuals with persistent dry mouth (xerostomia).

Disadvantages of Adhesives

• Difficult to remove denture adhesive from the mouth and denture.
• A false sense of security that a denture is still satisfactory may develop from using adhesives with a poorly-fitting denture that should be relined, replaced, or maintained in different ways.

Root Caries: An Epidemic of Age

People are living longer and keeping their natural teeth more than ever before. The advances in tooth retention, the desire to look one's best, and higher expectations about oral health have raised dental awareness among older adults.

With the significant increase in the older portion of society, with even greater increases expected, more older adults will have more teeth that are susceptible to root caries. Root caries may emerge as one of the most significant dental problems among older adults during the next decade. A recent study conducted by the National Institute for Dental and Craniofacial Research (NIDCR) showed that over half of older adults have decayed or filled root surfaces. The frequency of root caries is strongly age-dependent and will continue to be a major dental problem among the elderly.

Root caries lesions can be caused by new or primary root caries, caries around existing dental fillings or recurrent caries, and abrasion or erosion of the root surfaces. Root caries progress quickly due to the relatively soft nature of the root surface, as well as the risk factors associated with the incidence of root caries.

Risk factors associated with the high prevalence of root caries among older adults include decrease salivary flow or xerostomia, exposure of root surfaces due to periodontal (gum) disease, chronic medical conditions, radiation treatment for head and neck cancer, physical limitations, and diminished manual dexterity due to stroke, arthritis, or Parkinson's disease, cognitive deficits due to mental illness, depression, Alzheimer's disease or dementia, Sjögren's syndrome (an autoimmune disease), diabetes, poor oral hygiene, multiple medication use, and changes in dietary habits. One or more of these risk factors or life changes, which are more common among older adults, can increase root caries in an individual who has not had dental caries for many years.

Root caries can be a challenge for the dentist to treat depending on the size and the type of root caries lesion, the extent and rate of caries activity for that person, the physical and mental condition of the individual, and where the root caries are located in the mouth. Many root lesions have limited accessibility and visibility, are often more complicated by pre-existing extensive dental work, and are difficult to isolate from oral fluids during the restoration process. Also, many people who have widespread root lesions have limited tolerance for dental treatment because of medical conditions, illness, and mental health problems.
