This condition is also called as Edentulism. This is a condition where there are no teeth left in the oral cavity and all the teeth have fallen.
In this condition there will be great difficulty for the patient to chew any kind of hard food as the mucous membrane of alveolar ridge will be exposed and the patient has to get complete dentures.
There will also be shrinkage of the mandible inwards and the aesthetics of the patient will be affected very badly, and it also gives a very aged look to the patient, so the sooner the dentures are put the better it is.
There will be problem in speech and pronunciation, so the quality of the speech and the communicating power of the patient is reduced.
