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.

New Complete Dentures

Every patient is eager to see what their new dentures (or false teeth) look like, and for good reason. But how can you judge if it's really going to be grand?

Coco Chanel, the world-renowned fashion designer, once said that if you notice a lady's clothes, she's poorly dressed; if you notice the lady instead, she's impeccably dressed. That same philosophy can help prosthodontics wearers to assess for themselves what looks right.

During the wax try-in appointment, when you're "fine-tuning" your replacement teeth, you may be tempted to peer at them while holding them in your hands, or evaluate what you see in the mirror through bifocals. While this "view" will give you an idea of the construction of your new denture, it's not how other people will see it.

What goes into creating good complete dentures?

Your prosthodontist can create a rugged or delicate, masculine or feminine, assertive or passive, youthful or mature look. Youthfulness can be achieved by a curved smile line, showing the two front teeth more than those on each side, and having a darker translucent edge on those front teeth. False teeth can be brought down where they are more visible and placed further forward to plump out a thin upper lip. If teeth are arranged evenly in a flat line, it makes a person look older.

Any of these qualities can be realized in a new denture, but they won't show while it is in your hand. A good denturist invests time and all his care to make your denture look best, in your mouth, where it belongs. Look at your dentures in the mirror from a conversational distance, while you talk or smile. And if your friends don't notice it, your prosthodontist has done a good job.
