A dental abscess is a collection of pus that can form inside the teeth, in the gums, or in the bone that holds the teeth in place. It’s caused by a bacterial infection.
Types of Abscess
There are two types of abscess
- Periapical Abscess: An abscess at the end of a tooth is called a periapical abscess.
- Periodontal Abscess: An abscess in the gum is called a periodontal abscess.
Symptoms of a Dental Abscess
Symptoms of an abscess in your tooth or gum may include:
- An intense, throbbing pain in the affected tooth or gum that may come on suddenly and gets gradually worse
- Pain that spreads to your ear, jaw and neck on the same side as the affected tooth or gum
- Pain that’s worse when lying down, which may disturb your sleep
- Redness and swelling in your face
- A tender, discoloured and/or loose tooth
- Shiny, red and swollen gums
- Sensitivity to hot or cold food and drink
- Bad breath and/or an unpleasant taste in your mouth
If the infection spreads, you may also develop a high temperature (fever) and feel generally unwell. In severe cases, you may find it hard to fully open your mouth and have difficulty swallowing or breathing.
What Causes Dental Abscesses?
Your mouth is full of bacteria, which form a sticky film on your teeth called plaque.
If you don’t keep your teeth clean, acids produced by the bacteria in plaque can damage your teeth and gums, leading to tooth decay or gum disease.
The following can increase your chances of developing a dental abscess:
- Poor oral hygiene – plaque can build-up on your teeth if you don’t floss and brush your teeth regularly
- Consuming lots of sugary or starchy food and drink – these can encourage the growth of bacteria in plaque and may lead to decay that can result in an abscess
- An injury or previous surgery to your teeth or gums – bacteria can get into any damaged parts of the teeth or gums
- Having a weakened immune system – this includes people with certain underlying health conditions, such as diabetes, and those having treatment, including steroid medication or chemotherapy
What to Do If You Have A Dental Abscess?
if you think you have a dental abscess, the most important action that can be taken is an immediate visit to an emergency dentist, which will hopefully spell the end of the problem as soon as possible.
It’s important to get help as soon as possible, because abscesses don’t go away on their own. If the issue is ignored for a long period of time, the infected tooth may need tooth extraction, as the problem may spread to other areas of the mouth. Therefore, it is absolutely vital for individuals to ensure they visit a dental professional at the next possible opportunity.
Relieving Your Symptoms
While you’re waiting to see a dentist, painkillers can help control your pain.
Ibuprofen is the preferred painkiller for dental abscesses, but if you’re unable to take it for medical reasons, you can take paracetamol instead. Aspirin shouldn’t be given to children under 16.
If one painkiller doesn’t relieve the pain, taking both paracetamol and ibuprofen at the doses shown in the medicine leaflet may help. This is safe for adults, but not for children under 16.
It may also help to:
- Avoid hot or cold food and drink if it makes the pain worse
- Try eating cool, soft foods if possible, using the opposite side of your mouth
- Use a soft toothbrush and temporarily avoid flossing around the affected tooth
These measures can help relieve your symptoms temporarily, but you shouldn’t use them to delay getting help from a dentist.
Treatments for a Dental Abscess
Dental abscesses are treated by removing the source of the infection and draining away the pus.
Depending on the location of the abscess and how severe the infection is, possible treatments include:
- Removing the Affected Tooth (Extraction) – this may be necessary if root canal treatment isn’t possible
- Root Canal Treatment – a procedure to remove the abscess from the root of an affected tooth before filling and sealing it
- Incision and Drainage – where a small cut (incision) is made in the gum to drain the abscess (this is usually only a temporary solution and further treatment may be needed)
Local anaesthetic will usually be used to numb your mouth for these procedures. More extensive operations may be carried out under general anaesthetic (where you’re asleep).
Antibiotics aren’t routinely prescribed for dental abscesses, but may be used if the infection spreads or is particularly severe.
Preventing Dental Abscesses
You can reduce your risk of developing dental abscesses by keeping your teeth and gums as healthy as possible.
To do this, you should:
Use Floss: Use floss or an interdental brush at least once a day to clean between your teeth and under the gum line
Brush Twice a Day: Brush your teeth with a fluoride toothpaste twice a day – spending at least two minutes each time
Avoid Rinsing Your Mouth with Water or Mouthwash: After brushing because this washes the protective toothpaste away – just spit out any excess toothpaste
Cut Down on Sugary and Starchy Food and Drinks – particularly between meals or shortly before going to bed
Visit Your Dentist Regularly – your dentist or hygienist can suggest how often you should have a check-up, based on your oral health.
Will the infection return?
If an abscess is caught in time and the appropriate treatment is given, the infection should be removed and the tooth preserved. Therefore, it is vital to attend an appointment with a dental professional to stop the infection from returning.
A number of complications can be caused by the return of an infection, including the complete extraction of the tooth. Further problems can be caused beyond the infected area, which can spread to the skin causing soreness, swelling and discoloration
This issue can often spread from the tooth to the jawbone and bring on a condition called osteomyelitis, which can escalate to affect the bone marrow. The disease is a debilitating condition and can be very painful, which can bring on the requirement for surgery.
