Over time, people's teeth tend to naturally deteriorate. When a
tooth has deteriorated substantially, it often needs to be extracted.
And when multiple teeth are extracted, dentures may be the most
appropriate solution. Dentures can create a natural and healthy
looking set of teeth. As well, a properly fitting set of dentures
can greatly enhance your smile and sense of self-esteem.
Many types of dentures exist, including
complete and partial dentures. Complete dentures are used when few
of the original teeth remain. The dentist begins by removing any
remaining teeth so the dentures can be fitted. He or she then makes
a mold of the gums and sends it to a dental lab where customized
dentures are constructed. Patients are typically fitted with temporary
dentures until the permanent set of dentures have returned from
the laboratory. Partial dentures are prepared in much the same way
as a complete set, and are utilized when only a few teeth are missing..
If the roots of a patient's remaining teeth
(the tissue and gums) are strong, the dentist may suggest over dentures.
Over dentures fit on top of the remainder of teeth in the mouth.
With over dentures, the remaining teeth are resculpted and covered
with metal caps to stop future decay. The advantage of over dentures
is that they do not have to be relined as frequently as a complete
set of dentures because the jawbone and gums recede less. In addition,
over dentures create less occlusion (bite) problems than complete
dentures.
At first, your dentures will feel uncomfortable
because the gums and tissue are not accustomed to contact with man-made
relining material. Once placed, patients should wear their dentures
continually for the first few days to reduce the amount of swelling
that may occur in the mouth. This swelling typically recedes in
two to three days. Until patients become accustomed to their new
set of teeth, the dentures may feel loose and awkward while chewing
food. Eating soft food may also be necessary for the first few days.
Reading aloud helps to overcome any speech impediments that may
occur from the new dentures. Typically, lower dentures take longer
to get used to than upper dentures. The underlying jawbone may take
several months to completely heal and become accustomed to the dentures.
Once this occurs, the dentist removes the dentures and creates a
permanent lining for your teeth (a denture lining is the soft material
that cushions the contact between the denture and the gum tissues).
Proper care and cleaning will increase the
life of your dentures. Although they typically last five years,
proper care and minimal jaw recession can extend the life of dentures
up to 25 years. Dentures should be cleaned daily with a normal or
specially-made denture toothpaste. Once the swelling has reduced,
it is advisable to leave one or both dentures out at night to allow
the gum tissues to breathe. In order to prevent dentures from warping,
they should be left in water overnight. Over time, the lining of
the dentures may change, owing to the wear and tear of daily use.
In the case of tissue/bone shrinkage, worn down teeth, or breakage,
dentures may come loose and need to be remade.
