check_icon Research-backed

An Abscessed tooth in a child is characterized by the collection of pus inside the teeth, gums, or surrounding bone. It occurs as a result of bacterial infection. An abscess at the end of the tooth is called a periapical abscess, and an abscess within the gum is called a periodontal abscess.

A dental abscess is painful most times, but not always. It helps if you take your child to the dentist for timely treatment and management. Read this post to learn more about the causes, symptoms, diagnosis, and treatment for dental abscesses in children.

Causes Of Tooth Abscess In Children

The dental abscess is caused due to bacteria inside the teeth. The bacteria irritates the gum and causes inflammation. Gradually, the tooth becomes loose. The bacteria pools in the gap between the tooth and the gum causing an abscess (1).

Cavities lead to a periapical abscess. When the dental decay reaches the center of the tooth, it damages the tooth nerve, and the infection collects at the tip of the tooth root to form an abscess.

The bacteria present in the plaque can cause gum irritation, gum swelling, gum disease and periodontal infection. Periodontal space is present between the gums and teeth. Bacteria can collect in this space and may form abscesses (1).

Signs And Symptoms Of Tooth Abscess In Children

The following are the signs and symptoms of tooth abscess in children (1) (2) (2).

  • Sharp or throbbing pain in the affected tooth or gum
  • Teeth are sensitive to hot or cold food or drinks, and pressure
  • Red discoloration on the gums
  • Swollen gums
  • Ear pain on the same side of the affected tooth
  • Pain worsens on lying down and might cause sleep disturbance
  • Pus discharge from the gum
  • Swollen jaw
  • Swollen lymph nodes
  • Swollen neck
  • Fever
  • Bitter taste in the mouth
  • Bad breath

In severe cases, one may experience difficulties opening the mouth or problems with swallowing or breathing.

Untreated dental abscesses may lead to the following complications (4).

  • Loss of tooth
  • Blood infection
  • Spread of infection to adjacent soft tissues
  • Spread of the tooth infection to the jaw bone
  • Spread of the oral infection to the other areas of the body, therefore causing brain abscess, heart inflammation, pneumonia, etc.

Contact the pediatric dentist if you notice any of these symptoms (5).

  • Fever
  • Nausea or vomiting
  • Persistent redness or swelling
  • Difficulty in breathing

The dentist will thoroughly examine the tooth and the surrounding structures. The diagnosis includes tapping on the tooth using the blunt end of the mouth mirror. Pain on tapping or closely biting the teeth can indicate a dental abscess. The mobility of the teeth or the presence of cracks in the tooth are also checked. Dental caries is also evaluated in the teeth around the abscess.

Dental x-rays help the dentist determine the tooth causing the problem and gauge the infection (4).

Treatment For Dental Abscess In Children

Removing the source of infection and draining away the pus is important for treating a dental abscess. The following are the possible dental treatments based on the location and the severity of the oral infection (5) (4) (6).

  • OTC pain killers

OTC painkillers may help in providing some relief from toothache and fever.

  • Antibiotics

Antibiotic therapy helps reduce the severity of tooth infections. However, not all cases of dental abscess need antibiotics. Ensure completion of the entire course of antibiotics for your child upon prescription.

  • Root canal treatment

Root canal therapy is one of the most commonly used dental procedures to treat tooth abscesses. The infected dental pulp and abscess are removed from the tooth root before filling and sealing it.

  • Removal of the affected tooth

Tooth extraction might be recommended for severely infected teeth that cannot be saved by root canal treatment.

  • Incision and drainage

A small cut is made on the gum to drain the pus/abscess. It might relieve the swelling. However, this is only a temporary solution, and further dental treatment is suggested.

For severe dental infections, hospitalization may be needed. However, more extensive surgical procedures are rarely required and may be performed under general anesthesia (3).

A child’s tooth or gums should not be exposed to aspirin directly. It may cause the tissues to become more irritated and lead to mouth ulcers (5).

Dental abscesses can be prevented by taking measures to keep your teeth and gums healthy that promote dental health. The following tips can help your child prevent dental abscesses (5).

  • Ensure your child maintains proper dental hygiene to prevent cavities. Have your child brush their teeth twice daily with fluoridated toothpaste and a soft-bristle toothbrush. Moreover, as the Centers for Disease Control and Prevention reports, drinking fluoridated water prevents tooth decay in about 25 percent of children and adults.
  • Flossing the areas between the teeth can prevent plaque formation and gum diseases.
  • Have your child’s oral health evaluated by the dentist regularly.
  • Avoid giving excessive sugary food and drinks.
  • Offer a balanced diet with all vegetables and fruits.
  • Give a child-friendly mouthwash.

Frequently Asked Questions

1. Is a dental abscess an emergency?

A dental abscess that causes unbearable pain can require immediate treatment. Dental abscess-related emergency visits are common, and the incision and drainage may be treated in an emergency room with follow-up oral care (7).

2. Are dental abscesses common in children?

Although not all children may experience dental abscesses, it is fairly common and needs prompt medical attention (1).

Root canal, or the removal of the damaged tooth pulp, is done to preserve the integrity and function of the oral tissue among children. Although it is commonly done in children older than 12 years, it can be done for younger children in certain situations.
