Dentures are a removable replacement for missing teeth and adjacent tissues. They are made of acrylic resin, sometimes in combination with various metals.
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. A denture improves chewing ability and speech, and provides support for facial muscles. It will greatly enhance the facial appearance and smile.
Complete or full dentures are made when all of your natural teeth are missing. You can have a full denture on your upper or lower jaw, or both.
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 over time, especially during the period of healing 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 solution when several teeth are missing.
Removable partials usually consist of replacement teeth attached to pink or gum-colored plastic bases, which are connected by 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. Crowns on your natural teeth may improve the fit of a removable partial denture and they are usually required with attachments. Partials with precision attachments generally cost more than those with metal clasps.
Dentures today are made from very advanced materials designed to give you a natural appearance. Just like your teeth, dentures should be cared for with the same diligence. This means daily brushing and regular visits to your dentist.
Just like natural teeth, dentures need to be cleansed of plaque, food particles and other debris. Keeping your dentures in top shape will also help keep the soft tissues of your mouth healthy; an unclean or malformed denture can cause infections and irritation.
Remember to rinse and brush your dentures after every meal, and soak them in denture solution overnight. This also allows your gums to breathe while you sleep.
Here are some simple techniques for keeping your dentures clean:
- People can brush their dentures in a variety of ways. Some people use soap and water or a slightly abrasive toothpaste. Popular denture pastes and creams also can be used.
- Avoid using highly abrasive chemicals or pastes, or vigorously brushing with hard bristled toothbrushes. These can scratch or even crack.
- Hold your dentures gently to avoid loosening a tooth.
- Clean your dentures with cool or tepid water over a water-filled sink. Hot water may warp. A small washcloth placed in the bottom of the bowl will ensure that your denture isn’t damaged if it falls.
- Soak your dentures overnight in any commercially available product like Efferdent or Polident and remember to rinse your dentures before placing them back in your mouth.
- Remember to use a separate toothbrush to clean your own natural teeth, as well as all of your gum tissues. In lieu of a toothbrush, a soft washcloth may be used to wipe your gums.
Over time, even daily care of your dentures may require them to be cleaned by the dentist. A powerful ultrasonic cleaner may be used to remove hard accumulations of tartar and other substances.
