Dental Abscess
Dental abscesses can be painful but they can be treated relatively easily. A dental
abscess is formed when the dental pulp in the middle of the tooth dies and the pulp
chamber becomes infected. The build-up of pus can raise the tooth up within the
socket, making it feel tender when you bite down.
Tooth abscesses can make your jaw ache and feel tender when you chew. If the abscess
bursts, the pain may go, but you should still seek treatment.
The IDA recommends that it's important you see your dentist to make sure the
problem doesn't come back. Your dentist will discuss with you the possibilities
of placing a root filling in the tooth to prevent this from happening.
Abscess occur when tooth decay is left untreated and reaches the dental pulp . The
bacteria then spread into the root of the tooth to form an abscess. Avoiding treatment
or putting it off may be one of the reasons for an abscess starting.This is known
as Periapical abscess.
When bacteria which are present in plaque infect the gums the patient has periodontitis.
The gums become inflamed, which can make the periodontal ligament (tissue surrounding
the root of the tooth) separate from the base of the tooth. A periodontal pocket,
a tiny gap, is formed when the periodontal ligament separates from the root. The
pocket gets dirty easily and is very hard to keep clean. As bacteria build up in
the periodontal pocket, periodontal abscess is formed.
Patients can develop periodontal abscesses as a result of a dental procedure which
accidentally resulted in periodontal pockets. Also, the use of antibiotics in untreated
periodontitis, which can mask the symptoms of an abscess, can result in a periodontal
abscess. Sometimes gum damage can lead to periodontal abscesses, even if no periodontitis
is present.
Treatment
- Treating a periapical abscess - root canal treatment will be used
to remove the abscess. A drill is used to bore a hole into the infected tooth so
that the pus can come out. Any damaged tissue will be removed from the pulp. A root
filling is then inserted into the space to prevent subsequent infections.
- Treating a periodontal abscess - the abscess will be drained and
the periodontal pocket cleaned. The surfaces of the root of the tooth will then
be smoothed out by scaling and smoothing (planing) below the gum line. This helps
the tooth heal and prevents further infections from occurring.
Surgery for dental abscesses
Patients with a periodontal abscess and a recurring infection may have to have their
gum tissue reshaped and the periodontal pocket removed. This procedure will be performed
by an oral surgeon.
If the dental abscess recurs, even after surgery, the tooth may be extracted (taken
out).
What are the complications of a dental abscess?
In the vast majority of cases, complications only occur if the abscess is left untreated.
However, complications can occur, even after seemingly effective treatment, but
this is very rare.
Possible complications include:
Dental cysts -
A fluid-filled cavity may develop at the bottom of the root of the tooth if the
abscess is not treated. This is called a dental cyst. There is a significant risk
that the cyst will become infected. If this happens the patient will need antibiotics,
and possibly surgery.
Osteomyelitis - the bacteria in the abscess gets into the bloodstream
and infects the bone. The patient will experience an elevated body temperature,
severe pain in the affected bone, and possibly nausea. Typically, the affected bone
will be near the site of the abscess; however, as it may have spread into the bloodstream
any bone in the body may be affected. Treatment involves either oral or intravenous
antibiotics.
Cavernous sinus thrombosis
The spread of bacteria causes a blood clot to form at the cavernous sinus - a large
vein at the base of the brain. Cavernous sinus thrombosis is treated with antibiotics,
and sometimes surgery to drain the sinus. In some cases the condition can be fatal.
This is a very rare complication.
Ludwig's angina
This is an infection of the floor of the mouth when the dental abscess bacteria
spread. There is swelling and intense pain under the tongue and in the neck. In
severe cases the patient may find it hard to breathe. Ludwig's angina is a potentially
fatal condition. Patients are treated with antibiotics. In severe cases a tracheostomy
(procedure to open the airway) is performed if there are breathing problems.
Maxillary sinusitis
The bacteria spread into small spaces behind the cheekbones, called the maxillary
sinuses. This is not a serious condition, but can be painful, and the patient may
develop a fever and have tender cheeks. Sometimes the conditions resolves on its
own. Depending on the severity, the doctor may prescribe antibiotics.
Consult your dentist as soon as you notice a dental abscess.
Deep inside the tooth is a soft mass of tissue called the pulp. If the tooth is
damaged - either by injury or decay - it may cause the pulp to get infected. If
this happens, your dentist may carry out a root canal treatment, but if the infection
spreads to the end of the root and into the bone, the dentist may have to perform
an apicectomy.This is a type of endodotnic surgery.
During this treatment, which is done under local anaesthetic, the dentist makes
a very small cut in the gum, cleans out any infection and then puts a small filling
at the end of the root canal to stop any future infection. Once this is done, the
dentist stitches the gum - and, because the cut is made as far away from the tooth
as possible, there is little chance of visible scarring.
Apicectomies are relatively rare as they are only carried out when root canal treatment
has failed.
