The upper denture is properly held in place by a vacuum that is created between the denture and the roof of the mouth. On the bottom jaw, because of the horseshoe shaped arch, the stability of the lower denture is not as great. Nowadays, the literature discussing lower dentures agrees that the best solution is to locate 2 implants in the lower jaw in order to stabilize the denture.
Upon extraction of teeth, there is a natural absorption of the bone that supported the tooth. The majority of the bone absorption occurs in the first year following the extraction, but continues slowly throughout life. As a result of this, gaps are formed between the denture and the changing ridge of the gums, and it becomes necessary to fill in these gaps. This is called "padding the denture".
It is very important to arrive for periodical check-ups to examine whether there is need for padding. If one does not come for padding for an extended period of time, the gaps that are created cause instability and increasing pressure on the remaining ridge, which leads to accelerated absorption of even more bone.
Adaptation
The adaptation to the denture is not simple, and a lot of patience is needed upon entering this period. The difficulty arises from the very presence of a strange element in one's mouth. The need to eat with it and talk with it takes getting used to. The good news is that after several weeks one gets used to the denture, the ability to eat improves, and one's speech returns to regular.
It is important to mention that the ability to eat with a denture will never be the same as the ability to eat with teeth. According to research, the chewing forces with complete dentures are 5 times less than that of the forces of chewing applied with natural teeth. In order to improve function, one should consider additional implants. An addition of only a few implants will wonderfully improve one's quality of life. It creates stability for the denture and will improve chewing ability.
As you can read in the article on Implants, there is no limitation on the age of the patient eligible for implants. The treatment is suitable for patients of all ages (18-120). It is actually the elderly who have lost their teeth and want to return their oral function to its previous situation that need implants most. They are the ones who can most benefit from dramatic improvement in function. You can read more on this matter in the article on Dental Treatment in the Golden Age.
Upkeep
As with natural teeth, dentures need upkeep.
The dentures must be cleaned with soap and a special brush that can be bought at the pharmacy. It is important not to brush with regular toothpaste, which contains polishing granules that can erode the denture (and natural teeth if you brush too hard).
The denture must be soaked daily for at least 15 minutes in a solution containing disinfection tablets (such as Kukident). The denture can also be soaked throughout the night.
Lack of cleaning the denture will lead to the development of fungus in the mouth, inflammation, bad smells and staining of the denture.
It is recommended to remove the denture at night in order to allow the muscles of the mouth and the facial tissues to relax. Throughout the day the fallen tissues are stretched by the denture, the muscles participate in the support of the denture and need rest at night.

Denture Types
Denture On
This denture sits on stable teeth stumps that were left in place in order to support the denture. Keeping the stumps in place prevents bone absorption on the ridge.
Denture on Implants
2-4 implants in the bottom jaw, and a minimum of 4 implants in the upper jaw grant good stability for the denture and security in chewing and in speaking.
To conclude, dentures involves complex treatment. It is in essence a complete mouth rehabilitation. It is important that this treatment be performed by someone with in depth knowledge and experience so that the dentures don't look false, sit with comfort, and achieve utmost functionality in the mouth.
