Dry Mouth And The Denture Patient - Xerostomia

Xerostomia (Dry Mouth) and Wearing Dentures

To a great extent, dentures stay in place comfortably and in a stabilized manner by development of an intimate interface between denture surfaces and the soft tissues they rest upon. Presence of adequate amounts of saliva within this denture/tissue interface is essential. Without enough saliva, a denture will inadequately adhere to tissues, partly through loss of suction. In addition, tissues contacting a denture will become chafed and irritated without the lubricating effects of saliva.

Some Common Causes of Dry Mouth

• Medications: There are approximately 500 commonly prescribed medications that have xerostomia as a possible side effect, and this is a frequent cause of dryness.
• Aging: The amount of saliva produced by salivary glands lessens as a person ages.
li>Illnesses: Xerostomia is sometimes associated with certain illnesses or conditions such as chronic diarrhea, liver dysfunction, or Sjogren's syndrome.
• Radiation therapy: Radiotherapy that is used to treat some cancers may have reduced salivary gland function as a side effect.
• Habits: Chronic mouth breathing and inadequate fluid consumption often will cause dry mouth.

Approaches to Managing Dry Mouth

Before managing a persistent dry mouth, it is essential to first become aware of the problem, and then attempt to determine causation for the xerostomia. Sometimes the cause is easily eliminated, but in many instances, that is not possible, and the condition is persistent and often progressive. There are several approaches to managing dry mouth.

• Modify medications: If a certain medication is suspected of causing xerostomia, consultation with a person's physician may make it possible to use a different, but equally effective, drug that no longer causes dry mouth or causes it to a lesser degree. However, there often are not suitable alternatives for a particular person's individual problem. Under no circumstances should someone discontinue or attempt to change a medication without the explicit knowledge and approval of their physician -- to do otherwise may result in serious illness or death.
• Sialagogues: These are substances that stimulate the production of saliva. There are two important types of sialagogues. 1) Gustatory sialagogues such as sugar-free hard candies frequently will cause some increase in salivation, and citrus flavors such as lemon are sometimes more effective than others. While sugar-free, low-sticking gum has been suggested, the process of chewing gum could more easily irritate already poorly lubricated tissues by increasing denture movement. 2) Pharmaceutical sialagogues (called parasympathomimetic agents) sometimes improve salivation and must be prescribed by a person's physician if their health status allows such a consideration.
• Salivary substitutes: Salivary substitutes are commercially available solutions that help keep the mouth moist and more lubricated. These compounds usually must be applied frequently and they generally necessitate having a container of the substance nearby.
li>Water: Water is a salivary substitute and often is used in place of commercial salivary substitutes. Regularly moistening the mouth, and drinking increased amounts of water may both hydrate tissues and facilitate some increase in production of saliva in certain individuals. While increased intake of water is generally healthful, persons with certain medical conditions such as, but not limited to, congestive heart failure should first check with their physicians before significantly increasing their routine consumption of fluids.

Alternative Denture Therapy for Patients Suffering From Dry Mouth

Those patients who are not able to comfortably wear conventional dentures due to severe xerostomia might consider implant-supported dentures. If this course of treatment is pursued, intense oral hygiene practices are necessary to maintain healthy implants and avoid periodontal disease in the presence of reduced salivary production. A person should always consult with their dentist to determine which treatment is best for them.

Common Questions About Affordable Dentures

New experiences generate many questions. Here are some frequently asked questions patients often ask about dentures.

Affordable Dentures Are All the Same, Right?

No. Maintaining good oral health is important to denture wearers. Mail-order services offering discounts on dentures cannot provide the custom fit you need for good oral health. Poor-fitting dentures cause chronic irritation, contributing to mouth sores and changes in the bone or gum tissues. Your dentist wants you to enjoy a comfortable fit, and will carefully measure and prepare your mouth for affordable dentures. Dentists work with reputable dental labs where skilled technicians create your custom-fit, affordable dentures for maximum comfort.

Will My Eating Habits Need to Change?

Actually, there are very few eating restrictions for denture wearers. If you experience eating difficulties at any time, it is important to contact your dentist. Poor-fitting dentures can contribute to eating difficulties. Dentures that fit right are vital for enjoying a well-balanced diet that includes a wide assortment of foods.

Do I Have to Wear Denture Adhesives?

Dentures are custom-designed for a comfortable and good fit for you. As a result, they usually don't require the regular use of an adhesive, unless it's to stabilize dentures in need of repair. Poor-fitting dentures must be checked by your dentist as soon as possible to eliminate discomfort and the potential for irritation.

Will These "Permanent" Teeth Last a Lifetime?

Dentures are very durable but that doesn't make them indestructible. They can discolor, chip, break, and bend out of shape. With good care, affordable dentures should last for many years. Here are some tips for maintaining the appearance and extending the life of your dentures:

• Use a brush designed specifically for dentures and a denture cleaner. Regular toothpaste can be too harsh for dentures.
• Store dentures in a container of denture-cleaning solution or water. /li>
• Soak in warm, not hot water. Hot water can damage their shape.
• Use an effervescent cleansing tablet once a week to kill odor-causing bacteria.

Affordable dentures offer many benefits to the millions who wear them. While they take some initial adjustment, they can enhance your smile as well as your long-term confidence. Return to your dentist at least once a year to evaluate fit, appearance, and to receive an oral cancer screening.
