Dental abscess or tooth infection: treatment, home remedy, symptoms and causes

A dental abscess is an infection with pus localized around the tip of the tooth root (apex) due to bacteria that killed the dental pulp and try to spread outside the tooth canal. There are two most common abscess types: periapical abscess which affects the end of a tooth and the periodontal abscess that forms in the gingival tissue.

Statistics reveal that caries, broken teeth (trauma), severe gum disease (periodontitis) or a failed root canal treatment are the most frequent dental abscess causes.

Pain, redness, swelling and bad breath are the most common dental abscess symptoms usually treated with antibiotics like: amoxicillin, augmentin, keflex. Antibiotics are also useful to avoid the tooth infection spreads to the neck, maxillary sinus, jaw joint or ear.

Natural home remedies and over the counter medication are useful as pain relief or mouth disinfection (hydrogen peroxide). To lower the pressure inside the bump, your dentist may decide to drain the tooth abscess making the pus coming out. It can be a painful procedure but once done you will feel much more better.

In some cases there are risk factors that can worse the disease (diabetes, HIV).

The tooth abscess during pregnancy or breastfeeding has to be treated by a doctor instead of using home remedies.

Abscessed tooth symptoms

Cheek redness and swelling

The most characteristic dental abscess symptom is the swollen cheek. That is caused either by the pus accumulation and the increased blood quantity. In fact, the immune defenses (white blood cells) are transported by the bloodstream, which is why the infected area swells up and turns red or purple.

Gum boil with yellow or white head

A small to medium bump with a gum boil inside the mouth close to the tip of the dental element root. Usually referred as “yellow or white head”.

Bitter taste in your mouth

When the pus comes out from the abscess that drains on its own or because of the dentist treatment, you may feel a bitter unpleasant taste in your mouth. It is temporary and to get rid of that you just need to rinse your mouth with water or using an antibacterial mouthwash with chlorhexidine.

Ear, jaw and neck pain

some patients reported a mild to acute pain that affected their ear, jaw and neck on the same side as the affected tooth or gum.

Pain gets worse at night

This happens because of the position of your body. When you lay in the bed, the blood pressure in your infected tooth increase pressing against the nerve located in the tissue pulp within the dental root canal. To relieve the pain caused by the periodontal abscess you should put a couple of pillows behind your head.

Bad breath caused by pus

You may feel bad breath in the mouth (halitosis) coming from the infection area due to the pus and necrotic tissue smell.

Increased sensitivity to hot or cold drink and food

If your abscess is caused by a broken tooth or a deep caries, the toothache can suddenly come on or get worse if you drink or eat too hot or cold food  that’s because the dental nerve is leaved uncovered.

Difficulty to chew and swallow

The abscess symptoms listed above are the most common but there are additional signs to be taken into account.

If leaved untreated, the infection spreads causing you:

  • Fever;
  • Difficulty to wide open the mouth or swallow
    That happens because the tooth infection affects the jaw joint ;
  • Swollen neck lymph nodes.
  • Nausea;
  • Diarrhea
  • Headache
  • jaw numbness;
  • generally unwell feeling.

How dentists treat a tooth infection ?


The tooth abscess diagnosis is done by the dentist proceeding by steps;

  • The doctor will first collect the signs and symptoms reported by the patient;
  • The second step of the diagnosis involves the sensitive test. The endodontist will tab vertically on the painful tooth using the handle of the dental mirror. An abscessed tooth, in fact, is usually very sensitive to touches or pressure;
  • At this point the X-Ray exam can show the dentist how far the infection spread and whether a fistula or a cyst formed or not.
  • If the infection has already spread to other zones like neck or jaw joint, the X-Ray is not enough and the doctor usually prefers to rely on the CT scan.

Once the diagnosis is complete and the dentist has the whole clinical picture, it’s time to proceed with the most appropriate tooth abscess treatment or therapy.

Pus drainage procedure

The first goal of the dental abscess treatment is to reduce the pressure inside the swelling.

In order to drain the abscess a little cut of the tissue or boil is required. The dentist will then gently squeeze the bump to make the pus coming out. As soon as the pus starts to exit the pressure decreases and the pain calms down but it doesn’t mean that the problem is solved. The infected and necrotic tissue is still there and it is necessary to remove it to avoid the infection restarts again.

Root canal treatment or re-treatment

Since a deep caries is the most common cause of the infection of the pulp within a dental element, the root canal is the conventional dental abscesses treatment.

After providing you with the local anesthesia, the endodontist opens a little hole in the crown enamel to access the pulp chamber.

With the help of manual tools  the specialist will remove nerves, blood vessels, died cells and the infected necrotic material from the inside the affected tooth.

In order to disinfect the root canal and to kill bacteria, usually  sodium hypochlorite is injected in the tooth and immediately reabsorbed.

At the end of the canal therapy the dentist closes the canal using a temporary filling and a prosthetic crown. To complete the procedure a few medication are required.

When the infection is completely removed it is possible to close the hole using a special filling called gutta-percha.

In case the doctor doesn’t totally remove bacteria from the abscessed tooth, after some time the infection restarts again that’s why a second canal therapy is needed. This second procedure is called “root canal re-treatment”.


When the abscess affects posterior teeth like molar or premolar, it is more difficult to remove all the infected material accessing the area from the tooth enamel.

In this particular case some dentists prefer the apicoectomy approach instead of the root canal. In other words, instead to drill the crown, the endodontist cuts the gum and makes a small hole in the bone to reach the infected area by accessing the opposite side.

Tooth extraction

In case of the tooth is completely damaged by the caries and the dental abscess spread all around, the last chance is the tooth extraction and the disinfection of the hole leaved by the removed dental element (“alveolar socket” is the correct medical term).

Antibiotic and antibacterial mouthwash

This is a controversial topic in the dentistry field because some doctors believe that antibiotics are necessary to fight the tooth infection caused by an abscess while others consider them useless and harmful.
