Dentures must be handled with great care and placed in a container of water or denture cleaner when not being worn. They should never be placed in hot water, for they can be damaged or warped. They must be cleaned daily using a soft toothbrush with soap and water. The mouth should be rinsed daily without the dentures in place to clean off any plaque and reduce the risk of infection like candidiasis.
Although dentures have helped millions of people around the world in regaining the ability to eat the foods they want, there are several disadvantages associated with the dental appliance. Some of the drawbacks of dentures disappear once the patients get used to wearing the device. Other problems with dentures may become an issue for the patient and lead them to seek alternative treatments for missing teeth.
Dentures that fit well during the first few years after creation will not necessarily fit well for the rest of the wearer's lifetime. This is because the bone and mucosa of the mouth are living tissues, which are dynamic over decades. Bone remodeling never stops in living bone. Edentulous jaw ridges tend to resorb progressively over the years, especially the alveolar ridge of the lower jaw. Mucosa reacts to being chronically rubbed by the dentures. Poorly fitting dentures hasten both of those processes compared to the rates with well-fitting dentures. Poor fitting dentures may also lead to the development of conditions such as epulis fissuratum. In addition, the occlusion (chewing surfaces of the teeth) tends to wear away over time, which reduces chewing efficacy and decreases the vertical dimension of occlusion, (the "open-ness" of the jaws and mouth).
Although dental implant success rates are high, there are cases in which the implant will fail. Most cases of implant failure can be prevented if the patient maintains his or her oral health and chooses a qualified implant dentist to plan and perform the procedure. Dental implants are more likely to fail in the maxilla (upper jaw) than in the mandible (lower jaw). Possible reasons for implant failure include:
Once the relative position of each arch to the other is known, the wax rim can be used as a base to place the selected denture teeth in correct position. This arrangement of teeth is tested in the mouth so that adjustments can be made to the occlusion. After the occlusion has been verified by the dentist or denturist and the patient, and all phonetic requirements are met, the denture is processed.
