Dental Health and Dentures

A denture is a removable replacement for missing teeth and surrounding tissues. Two types of dentures are available — complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.

Complete Dentures

Complete dentures can be either “conventional” or “immediate.” Made after the teeth have been removed and the gum tissue has begun to heal, a conventional denture is ready for placement in the mouth about eight to 12 weeks after the teeth have been removed.

Unlike conventional dentures, immediate dentures are made in advance and can be positioned as soon as the teeth are removed. As a result, the wearer does not have to be without teeth during the healing period. However, bones and gums shrink over time, especially during the healing period following tooth removal. Therefore a disadvantage of immediate dentures compared with conventional dentures is that they require more adjustments to fit properly during the healing process and generally should only be considered a temporary solution until conventional dentures can be made.

Partial Dentures

A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes connected by a metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw. A fixed bridge replaces one or more teeth by placing crowns on the teeth on either side of the space and attaching artificial teeth to them. This “bridge” is then cemented into place. Not only does a partial denture fill in the spaces created by missing teeth, it prevents other teeth from changing position. A precision partial denture is removable and has internal attachments rather than clasps that attach to the adjacent crowns. This is a more natural-looking appliance.

What Do New Dentures Feel Like?

New dentures may feel a little odd or loose for a few weeks until the muscles of the cheeks and tongue learn to keep them in place and you get comfortable inserting and removing them. Also, it is not unusual for minor irritation or soreness to occur and for saliva flow to increase when you first start wearing dentures, but these problems will diminish as the mouth adjusts.

The cost of a dental bridge?

A dental bridge cost from about $2,000 and to more than $5,000. The type of bridge and its material can greatly impact the amount you pay. Some dental insurance plans help to cover the cost of a dental bridge.

What are the teeth made of?

The teeth of a denture are typically made from various types of resin or porcelain. The latter was traditionally the preferred material because it was stronger and more durable. Porcelain is still used in some instances and has a number of advantages:

  • A glass-like ceramic material, porcelain has the same translucent appearance as natural tooth enamel and can be color-matched closely with other teeth in the patient’s mouth.
  • Porcelain teeth feel similar to natural teeth. This makes them easier to adapt to than other materials.
  • The heating process used to make them causes the dentures to become considerably harder, which means they last longer.

The main disadvantages of porcelain dentures, however, are that they’re breakable if dropped on a hard floor and they can wear down natural teeth if they bite against them. Porcelain is better used in full dentures than in partials for this reason. More recently, however, acrylic resin has become the go-to material for denture teeth. Having the correct bite, and alignment of teeth with dentures can be crucial for comfortable wear and use; the way our teeth come together is called occlusion. Acrylic adheres more securely to the denture base and is easier to adjust to achieve the correct occlusion than harder porcelain teeth. It’s also significantly less expensive than porcelain, and much lighter in weight. The disadvantage of teeth made from acrylic resin is that they wear faster than porcelain teeth, which changes the occlusion. Dentures made from acrylic resin teeth may need to be replaced every five to eight years as a result, but they are still far stronger than the plastic items used in the past.

What is the framework made of?

Dentures require a framework to support them, which is usually called a full or partial plate. This plate can be made from rigid acrylic resin or a type of flexible (nylon) polymer. Or it can be molded from chrome cobalt metal. The dentist takes an impression of the patient’s gums, which is used to create a mold. This mold is then used as the basis of a wax model to which the teeth are added. The model is tested in the patient’s mouth to confirm it will be suitable in size and color, and for the formation of a plate that fits snugly in the mouth. Plates made from acrylic resin are compatible with dentures that require an artificial gum line because the material can be tinted to resemble the patient’s natural gum color. Metal plates, however, carry less risk of breaking. They are also stronger and provide a better fit. This makes metal ideal for partial plates that are fully hidden behind the remaining natural teeth.

Understanding the strengths and weaknesses of your dentures can tell you how long you can expect them to last. The lifespan of a denture also depends on your oral hygiene regimen, so it’s essential to clean them daily. Above all, take care of your natural gums to keep them healthy enough to wear dentures, using dental rinse to prevent the bacteria that causes painful gingivitis and bleeding.
