Dental check-up
Your
dentist will inspect each tooth using small instruments inserted into your
mouth, such as a mirror and probe (a fine, pick-like tool). The dentist looks
for issues such as tooth decay, gum disease and other conditions.
If a
suspected dental problem is difficult to see (for example, possible decay
between two touching teeth), the dentist may need to take x-rays. If a problem
exists, your dentist will explain the treatment options and give you an
estimate of the cost and likely waiting time.
Scaling and cleaning
Scaling and
cleaning involves the removal of built-up debris from the teeth. This may
include food particles, soft plaque or hard calculus (caused by the continual
accumulation of minerals from saliva and plaque, sometimes called tartar). The
dentist or hygienist then cleans and polishes your teeth using a rotating brush
with abrasive paste. This helps treat and prevent gum disease.
You will be
given instructions on how to keep up your oral hygiene between appointments, as
this is important to help maintain healthy gums.
Fissure sealants
Sealants
protect teeth from decay. Any tooth that has deep grooves or fissures can be
treated, but the most commonly treated teeth are the molars and premolars.
A sealant
is a durable liquid plastic that is painted on to the biting surface of a
cleaned tooth. It forms a physical barrier that stops food and other bacteria
from collecting in the fissures of the tooth. Fissure sealants are commonly
recommended for children, as they reduce the risk of decay in permanent teeth.
Dental fillings
Tooth decay
that has caused a cavity is treated with dental fillings. The dentist uses a
drill and other tools to remove the decay. The cavity is cleaned, dried and
sealed with a filling material.
A variety
of materials are available for filling the cavity. You will be given advice on
the most suitable material, based on the size, shape and location of the
required filling. A common choice is tooth-coloured filling material, which can
restore the aesthetic appearance of the tooth, as well as its shape and
function.
Restoring damaged teeth
Your
dentist can suggest various treatments to restore damaged teeth. These
treatments help restore the appearance, shape and function of your teeth. They
include:
Bonding –
chipped, gapped, discoloured or oddly shaped teeth can be treated with bonding.
A tooth-coloured resin filling is applied to achieve a more regular look to the
affected tooth. However, the resin may need to be replaced occasionally.
Veneers –
teeth can be fitted with porcelain or resin veneers. A veneer is usually 0.5 mm
thick and is permanently glued to the front of the tooth.
Crowns –
these are caps that are permanently cemented or bonded to a tooth. Crowns are
made of porcelain and can be matched to the colour of the existing tooth.
Root canal treatment
Root canal
treatment is a procedure that replaces a tooth’s damaged or infected pulp with
a filling. The ‘pulp’ is a sensitive tissue that provides oxygen, nutrients and
feeling to the tooth. It is housed in the hollow centre of a tooth (pulp
chamber), along with blood vessels and nerves. Once a tooth is fully formed,
nutrition for the tooth comes from the tissues surrounding the root and the
tooth can function without its pulp. During root canal treatment, the pulp is
removed from a tooth. The dentist cleans and shapes the root canals with a
drill and small files. The tooth’s interior is cleaned, dried and packed with a
filling material that goes all the way down to the end of the root. An
artificial biting surface is created for the tooth out of dental amalgam,
composite material or a crown. This also protects the tooth from fracture,
which can occur after root canal treatment. A root canal may need to be
performed over a number of appointments.
Tooth removal (extraction)
Modern
dentistry and oral health practitioners aim to preserve natural teeth. However,
extensively damaged or badly decayed teeth may need to be removed (extracted).
The dentist may also recommend extraction to deal with wisdom teeth that are
causing problems.
Wisdom
teeth can contribute to various dental problems, including overcrowding of the
existing teeth and impaction (the wisdom tooth grows at an angle and butts into
the next-door molar or the gum). A tooth may be removed while under local
anaesthetic. Sedation or general anaesthesia may also be offered depending on
the difficulty of the procedure.
Fitting of dentures
Dentures
(also known as ‘false teeth’) are artificial teeth that replace some or all of
your natural teeth and can be removed at will by the person. An ‘immediate’
denture can be made while you still have some of your teeth. It is fitted on
the day your teeth are removed. However, changes to the jawbone during the
healing process may cause the denture to gradually loosen.
Within a
few months, the immediate denture may need relining of its inner aspect to
improve the fit. Alternatively, a denture can be made a few months after teeth
are removed. This allows time for the jawbone to heal and means that the
denture should have a better fit.
Fitting of mouthguards
Mouthguards
are protective devices that cover the teeth and gums to prevent injury to the
teeth, gums, lips, tongue and jaws. They are frequently used while playing
sport to prevent damage from accidental or deliberate knocks to the face. A
dentist or oral health professional can take impressions of your teeth and make
a well-fitting, comfortable mouthguard for your protection.
Dental implants
A dental
implant can be used to replace missing teeth. An implant is an artificial tooth
that consists of a small titanium screw that is fixed into the jaw and an
artificial tooth that is fitted on top of that. Several dental appointments are
required for the measuring, design, and fitting of the implant.
In time,
the implant becomes fused with the bone of the jaw. Implants have a high
long-term success rate. However, this is a specialised field of dentistry, so
your dentist or oral health professional may need to refer you.
