What are dentures?
Dentures are replacements for missing teeth that are removable from your mouth for cleaning. Impressions are taken in your mouth and dentures are custom made in a dental laboratory.
They can be made of porcelain, usually bonded to metal, or entirely of metal, usually gold. The adjacent natural teeth are prepared like a crown preparation and a temporary bridge is usually fitted while the laboratory constructs the new bridge.
These bridges are usually cheaper and preserve more tooth structure, as they require little or no preparation, but the abutment tooth needs to be strong and healthy and should not have any large fillings.
How long do dentures last?
After teeth are extracted, the bone that held the teeth in the jaw starts to reshape and disappear. This happens more rapidly at first but continues for many years causing the denture to become loose. Dentures may then need relining or remaking to improve their fit. Depending on their design, metal dentures tend to last longer as they are stronger and because they are largely supported on the teeth, their fit is less likely to be affected by bone shrinkage.
How can I look after my dentures?
Denture cleanliness is essential to prevent bad breath, poor appearance and the harmful effects of plaque and calculus build up on your teeth and gums, so it is important to clean your teeth and your dentures, if possible, after every meal. We will give you advice on how to clean your dentures when we fit them. Many patients like to keep their dentures in at night, but if you do take your dentures out, never let them dry out.
Why are upper dentures easier to wear than lower dentures?
The shape of your ridges and palate can influence how well your dentures fit and how much suction you have to hold them in. Most complaints are about lower dentures. This is because there is no large area for denture suction, unlike the palate, and the ridges are much smaller than the upper ridges. The lips, cheeks and tongue are also trying to dislodge the denture. The lower ridge also shrinks up to four times more than the upper ridge causing the denture to become looser much quicker.
