A tooth abscess is a serious condition. Complications include not only loss of the tooth but also of general health. Targeting this condition should never be put off till a later date.

We have broken down the most important facts on the subject. Read the following guide to learn about what a tooth infection is, its causes, as well as treatment options available.

What is a tooth abscess?

A dental abscess, sometimes called an infection, is a pocket of pus somewhere around the tooth. It can lead to moderate or even severe pain. You may feel discomfort in different parts of your mouth, head, and neck. Many patients report pain in their ear, especially if the abscess has formed in or around a molar tooth.

There are 3 regions where the cyst may appear:

  • A periapical abscess is on the tip of the root.
  • A periodontal abscess is in the gum around the root.
  • A gingival abscess forms on the gums surrounding the tooth.

The absence of pain does not always mean the absence of disease. More often than now, a dental abscess will be painless until it very quickly presents as severe pain.

Tooth abscess stages

The development of a tooth infection can be split up into 6 stages. Those include:

  • white spotting,
  • enamel decay,
  • decay of dentin,
  • infection of the pulp,
  • formation of the abscess,and
  • loss of the tooth.

It’s hard to say how long each step might take, as this depends on many factors including oral hygiene, smoking and drinking habits, as well as whether or not the patient targets the issue at all.

Obviously, the sooner you act on it, the less damage a tooth abscess will cause. Each step may be completely void of symptoms such as pain. This is why regular check ups are so important. A dentist will be able to catch signs much earlier than you.

Home remedies for dental abscess

There are a few things you can do at home before visiting a dentist. If you are experiencing pain, take an OTC painkiller with adherence to instructions on the packaging. In the case that you have any inflammation, consider taking ibuprofen. Rinse your mouth with saltwater solution.

The most important thing, though, is to restrain from bursting the cyst yourself. This is incredibly dangerous. By applying pressure incorrectly you can make the pocket burst towards the inside of your body.

The first step is to remove the pus from its pocket. A cut will be made to release the liquid. This relieves pain significantly. The area will then be cleaned with saline solution.

If the dental abscess was caused by a foreign object, the obvious solution is to remove it. This could be, for instance, a popcorn hull, a toothbrush bristle, or a tooth fragment. The dentist will then rinse the area with saline solution.

In cases where the patient’s immune system is weakened or if the infection has spread considerably, an antibiotics treatment may be prescribed. Nonetheless, the source of infection will have to be eliminated, usually through RCT.

If the tooth was extracted, antibiotics are usually not necessary, as the infection is removed along with it.


Yes. Tooth infections can not only lead to loss of dentition, but they can also spread to the rest of your body. If your blood becomes contaminated, you may be at risk of meningitis or sepsis. Both are life-threatening conditions.

There is no time frame here. A dental abscess is something you should treat right away. If you note any symptoms, don’t wait, as it can become more dangerous and cause more damage.

Nonetheless, abscesses can show up in as little as 3 months and be very severe or they could be festering for years with no signs. The best thing to do is to stay up-to-date with preventive X-rays and exams.

The most important thing is to focus on hygiene. Brush and floss your teeth at least twice a day, ideally after every meal. Don’t skip out on professional cleanings and regular checkups at the dentist to catch any problems early on. Also, remember to change out your toothbrush every 3-4 months.

Secondly, incorporate fluoride into your diet and routine. It helps remineralize your teeth and keeps them strong. Drink fluoridated water and use toothpaste that contains this mineral. A lot of mouthrinses have fluoride content as well. In terms of do’s, maintain a healthy diet. Lots of fruits and vegetables help prevent your teeth from becoming fragile. When it comes to don’ts, sugary snacks and drinks are your enemy. Avoid any tobacco products as well.

Dentists and doctors commonly prescribe antibiotics of the penicillin class, such as penicillin or amoxicillin. A course of such medication may not be enough, however. A medical professional should drain the pus from the pocket to remove dead tissue from your mouth.

No. Do not touch your abscess yourself. It may relieve pain if done correctly, but you run a huge risk of introducing the bacteria into your bloodstream. The pocket may not burst towards the outside. This can have tragic consequences.
