Different Types of Dental Fillings
2
A dental filling is a restorative option that is
given to a tooth that has been infected by
bacteria. Bacterial invasions proceed in
different ways. Sometimes a person can suffer
from gum disease, but sometimes a person can
develop dental caries. Dental decay usually
begins at the grooves and fissures found at the
occlusal table of the mouth.
3
These areas collect much food that allows
bacteria to thrive, and bacteria begins to eat
away on the healthy tooth structure, initiating
disease. At its early stages, dental fillings can
resolve this issue. This involves the cleansing
of the tooth of diseased tissue by drilling,
after which appropriate dental fillings are
provided to seal the prepared cavity.
4
Dental fillings can be classified in different
ways According to the nature of the cavity and
the preparation. According to the progression of
the disease, tooth decay may proceed in various
ways and it may be small or large, depending on
how severe the infection has spread.
5
The most common cavities are those that develop
from the central fossa, but there are other types
of caries classifications - the nature of the
disease infection will dictate the type of tooth
preparation required. Class I caries are the
ones previously mentioned. These are caries that
develop on the occlusal table, affecting a single
surface of the tooth.
6
Class II caries are those that involve the
occlusal surface as well as any of the proximal
walls, thus involving two surfaces. Sometimes it
could involve both proximal walls, involving
three surfaces. Class III caries are smooth
surface caries limited to a single proximal
surface and is usually found on the anterior
teeth.
7
Class IV caries are more extensive smooth
surface caries that involve the proximal surface
and extends to the incisal or biting surface of
the teeth. Class V caries are smooth surface
caries located on the facial surface of the teeth
usually at the necks of the teeth, following the
shape of the gingiva.

According to the technique. There are two main
techniques that are followed for dental filling
procedures, direct and indirect. Direct dental
fillings are traditionally practiced in dental
offices and they are performed inside of the
mouth. Indirect dental fillings are more
complicated and they require an extra step which
involves taking a dental impression for cast
fabrication,
9
wherein the fillings will be constructed with.
Indirect dental fillings are also known as inlays
and onlays and they are permanently installed in
the teeth with an adhesive or cement. According
to the material used, dental fillings can be
classified as either metal or tooth-colored.
Metal fillings such as gold and silver amalgam
are the traditional material of choice and
10
they were popular because of strength.
Tooth-colored fillings are more aesthetic and so
much more popular nowadays. They are available as
composite resin, ceramic and porcelain, and may
be given to direct or indirect procedures.

When you are receiving a dental filling, you are
given the decision to opt for the technique and
the material. The nature of the disease infection
dictates the type of tooth preparation, you
cannot control this.http//mydentistupland.com/
