Tooth abscess

A tooth abscess is a mass of pus located at the root of the tooth or between the tooth and the gum.

It can affect both men and women, regardless of age.

When the tooth abscess is not treated, it can reach the bone of the tooth and spread locally, forming a serious infection: cellulite, which has nothing to do with the homonymous "cellulite" that describes the effect of "orange peel".


Dental abscesses occur more frequently:

  • As a result of untreated tooth decay;
  • As a result of a broken tooth;
  • After a gum disease (periodontitis)


Dental abscesses are provocative:

  • Swelling and redness of the gums
  • Pain, especially when chewing.

It is essential to consult a dentist as soon as the infection appears.

If left untreated, dental abscesses can cause

  • Fever;
  • General Fatigue
  • Headaches.

In some cases, the pain can be relieved by a spontaneous discharge of pus.

Prevention advice

To avoid the appearance of a dental abscess and limit the risks, it is essential to adopt good oral hygiene, with brushing the teeth three times a day after each meal.

Regular dental check-ups (twice a year for children and adults) with scales are recommended.

It is preferable to limit the consumption of sugar and tobacco because they promote the multiplication of microbes in the mouth.


During the consultation, the dentist will take an x-ray of the teeth to check that the abscess has not reached the bone of the tooth.

After treatment of the tooth abscess, an x-ray check should be performed a few weeks later. This confirms that the abscess is gone and if the tooth is badly damaged, a crown can be considered.


Rinse your mouth well with cold water to relieve a tooth abscess.

A local antiseptic mouthwash can temporarily soothe an abscess of the gums.

For pain, prefer aspirin or ibuprofen (unless contraindicated) to paracetamol for its anti-inflammatory action.

Treatment of a tooth abscess at the dentist's office

To evacuate the pus, the dentist makes an incision in the abscess, under local anesthesia if it is in the gum, and establishes a treatment with antibiotics.

However, if the injury is at the tip of the root, the practitioner cleans the inside of the tooth canal and then leaves it open to the air.

Prescribe antibiotics and mouthwash for one week.

When the treatment is finished, he fills the hole with a filling paste that allows the tooth to heal.


While waiting for the dental consultation, it is possible to take Pyrogenium 9 CH, 1 granule morning and afternoon.

As soon as the abscess appears, it is useful to take it in addition:

  • If the gum is pink, Apis mellifica 9 CH, 3 granules 3 times a day;
  • When the mucosa is red, Belladonna 9 CH, 3 granules 3 times a day;
  • If the gum is purple, Lachesis mutus 9 CH, 3 granules 3 times a day.

For a few days, alternate with Mercurius solubilis 5CH and Ferrum phosphoricum 5CH, 1 granule of each every 2 hours.
