Dentures

A denture is a removable replacement for missing teeth and adjacent tissues. It is made of acrylic resin, sometimes in combination with various metals.


TYPES OF DENTURES:

Complete dentures replace all the teeth, while a partial denture fills in the spaces created by missing teeth and prevents other teeth from changing position.

Candidates for complete dentures have lost most or all of their teeth. A partial denture is suitable for those who have some natural teeth remaining, which are strong enough to maintain a partial denture. A denture improves chewing ability and speech, and provides support for facial muscles. It will greatly enhance the facial appearance and smile.

Complete dentures are called "conventional" or "immediate" according to when they are made and when they are inserted into the mouth. Immediate dentures are inserted immediately after the removal of the remaining teeth. To make this possible, the dentist takes measurements and makes the models of the patient`s jaws during a preliminary visit.

An advantage of immediate dentures is that the wearer does not have to be without teeth during the healing period. However, bones and gums can shrink and resorb during the course of normal healing, especially in the first six months after the removal of teeth. When gums shrink, immediate dentures may require rebasing or relining to fit properly. A conventional denture can then be made once the tissues have healed. Healing may take at least 6-8 weeks.

An overdenture is a removable denture that fits over a small number of remaining natural teeth or implants. The natural teeth must be prepared to provide stability and support for the denture.

Partial dentures are often a good temporary solution when a tooth will be replaced by an implant in the future.

Removable partial dentures usually consist of replacement teeth attached to pink or gum-colored plastic bases, which may also be connected by a metal framework. Removable partial dentures attach to your natural teeth with metal clasps or devices called precision attachments. Precision attachments are generally more esthetic than metal clasps and are nearly invisible, however not every tooth can support a precision attachment. Crowns on your natural teeth may improve the fit of a removable partial denture and they are usually required with attachments. Dentures with precision attachments generally cost more than those with metal clasps.

HOW ARE DENTURES MADE?

The denture process takes about one month and 5-7 appointments: the initial diagnosis is made; an impression and a wax bite are made to determine vertical dimensions and proper jaw position; a "try-in" is placed to assure proper color, shape and fit; and the patient`s final denture is placed, following any minor adjustments.

GETTING ACCUSTOMED TO A DENTURE

For the first few weeks, a new denture may feel awkward or bulky. However, your mouth will eventually become accustomed to wearing it. Inserting and removing the denture will require some practice. Your denture should easily fit into place. Never force the partial denture into position by biting down. This could bend or break the clasps, or injure yourself.

At first, you may be asked to wear your denture all the time. Although this may be temporarily uncomfortable, it is the quickest way to identify those denture parts that may need adjustment. If the denture puts too much pressure on a particular area, that spot will become sore. Your denture can be adjusted to fit more comfortably. After making adjustments, you may need to take the denture out of your mouth before going to bed and replace it in the morning.

Start out by eating soft foods that are cut into small pieces. Chew on both sides of the mouth to keep even pressure on the denture. Avoid sticky or hard foods, including gum. You may want to avoid chewing gum while you adjust to the denture.

CARE OF YOUR DENTURE

It's best to stand over a folded towel or a sink of water when handling your denture, just in case you accidentally drop it. Brush the denture (preferably with a denture brush) daily with a tartar control toothpaste to remove food deposits and plaque, and keep it from becoming permanently stained. Avoid using a brush with hard bristles, which can damage the denture. Look for denture cleansers with the American Dental Association (ADA) Seal of Acceptance. Pay special attention to cleaning teeth that fit under the denture`s metal clasps. Plaque that becomes trapped under the clasps will increase the risk of tooth decay, and cause bad breath.

Hand soap or mild dishwashing liquid to clean dentures is also acceptable. Other types of household cleaners and many toothpastes are too abrasive and should not be used for cleaning dentures. A denture could lose its proper shape if it is not kept moist. At night, the denture should be placed in soaking solution or water. However, if the appliance has metal attachments, they could be tarnished if placed in soaking solution.

Even with full dentures, you still need to take good care of your mouth. Every morning, brush your gums, tongue and palate with a soft-bristled brush before you put in your dentures. This removes plaque and stimulates circulation in the mouth. Selecting a balanced diet for proper nutrition is also important for maintaining a healthy mouth.

ADJUSTMENTS

Over time, adjusting the denture may be necessary. As you age, your mouth naturally changes, which can affect the fit of the denture. Your bone and gum ridges can recede or shrink, resulting in a loose-fitting denture. Loose dentures can cause various problems, including sores or infections. Dentures that do not fit properly can be adjusted. Avoid using a do-it-yourself kit to adjust your dentures, as this can damage the appliance beyond repair. Glues sold over-the-counter often contain harmful chemicals and should NEVER be used on a denture.

If your denture no longer fits properly, if it breaks, cracks or chips, or if one of the teeth becomes loose, see your dentist immediately. In many cases, dentists can make necessary adjustments or repairs, often on the same day. Complicated repairs may require that the denture be sent to a special dental laboratory.

Over time, dentures will need to be relined, re-based, or re-made due to normal wear and normal oral changes. To reline or re-base a denture, the dentist uses the existing denture teeth and refits the denture base or makes a new denture base. Dentures may need to be replaced if they become loose and the teeth show signs of significant wear.

COMMON CONCERNS

Eating will take a little practice. Start with soft foods cut into small pieces. Chew slowly using both sides of your mouth at the same time to prevent the dentures from tipping. As you become accustomed to chewing, add other foods until you return to your normal diet.

Continue to chew food using both sides of the mouth at the same time. Be cautious with hot or hard foods and sharp-edged bones or shells.

Some people worry about how dentures will affect their speech. Consider how your speech is affected when you have a number of your natural teeth missing. There will be an adjustment period but over time your oral and facial muscles responsible for speech will adapt, and your speech feel and sound normal once again.

Pronouncing certain words may require practice. Reading out loud and repeating troublesome words will help. If your dentures "click" while you`re talking, you may need to speak more slowly. You may find that your dentures occasionally slip when you laugh, cough or smile. Reposition the dentures by gently biting down and swallowing. If any speaking problems persist however, consult your dentist.

DENTURE ADHESIVES

Denture adhesives can provide additional retention for well-fitting dentures. Denture adhesives are not the solution for old, ill-fitting dentures. A poorly fitting denture, which causes constant irritation over a long period, may contribute to the development of sores. These dentures may need a reline or need to be replaced. If your dentures begin to feel loose, or cause pronounced discomfort, consult with your dentist immediately.
