Swelling of the face or gums. How to respond immediately to prevent serious infections.

1. What should you do if you notice swelling in your child’s mouth?

When you notice swelling in your child’s mouth or face, it is important to act immediately to reduce discomfort and manage the situation:

  • Observe the area: Check whether the swelling is accompanied by redness, pain, fever or discharge of pus. These symptoms may indicate an infection or abscess.
  • Clean the mouth: Rinse the child’s mouth with lukewarm salt water to reduce inflammation and keep the area clean.
  • Apply a cold compress: Place a cold compress or ice wrapped in a cloth against the cheek near the swollen area. This helps reduce pain and swelling.
  • Avoid pressure on the area: Do not press or try to drain the swelling, as this may make the condition worse.
  • Contact the paediatric dentist: If the swelling does not subside or is accompanied by serious symptoms, call the paediatric dentist immediately for guidance and a possible visit.

A prompt response is important to prevent complications and ensure your child’s comfort.

2. Possible causes of swelling in the mouth

Swelling in a child’s mouth or face may have various causes:

  • Infections: The most common causes include tooth decay that has developed into an abscess, gum infections or sinusitis.
  • Injuries: A blow to the mouth can cause swelling and inflammation of the tissues.
  • New teeth erupting: The eruption of permanent or primary teeth may cause slight swelling of the gums.
  • Allergic reactions: Certain foods or medicines can cause swelling of the mouth or face as a reaction.
  • Infected injuries: Sores in the mouth or around the teeth that have not been cleaned properly can lead to infection and swelling.

A correct diagnosis by the paediatric dentist is essential to identify the cause and begin appropriate treatment.

3. When should you visit the paediatric dentist?

A visit to the paediatric dentist is necessary if the swelling is accompanied by any of the following:

  • Pain that does not subside: Pain may indicate an abscess or serious infection.
  • Fever: Fever may indicate an infection requiring immediate treatment.
  • Pus or an unpleasant smell: These signs indicate an abscess or infection in the oral tissues.
  • Difficulty swallowing or breathing: These signs require emergency medical intervention.
  • Duration of swelling: If swelling remains for more than 24 hours, it is important for a specialist to examine it.

The paediatric dentist can assess the condition, identify its cause and begin the appropriate treatment, providing immediate relief and preventing further complications.

4. Practical ways to provide relief at home

If your child has swelling in the mouth, there are several things you can do at home to relieve discomfort before visiting the paediatric dentist:

  • Use a cold compress: Place a cold compress or ice wrapped in a clean cloth against the cheek near the swollen area.
  • Salt-water rinse: Mix half a teaspoon of salt into a glass of lukewarm water. Ask the child to rinse their mouth gently.
  • Give pain relief: If the pain is severe, you may give age-appropriate pain medicine, but only according to the doctor’s instructions.
  • Avoid irritating foods: Choose soft, lukewarm foods and avoid very hot, cold or spicy foods.

These measures provide temporary relief but do not replace a visit to the paediatric dentist if symptoms persist.

5. Common treatments for swelling

Treatment depends on the cause of the problem. At our practice, we provide the following treatments as appropriate:

  • Antibiotics: If swelling is caused by an infection or abscess, antibiotics may be prescribed.
  • Draining the abscess: In cases of serious abscesses, we drain them to reduce swelling.
  • Dental treatment: If swelling is caused by decay or injury, fillings or root canal treatment may be required.
  • Treatment for gum inflammation: If gingivitis is the cause, we provide cleaning treatments.

7. How to prevent swelling in the future

Prevention is the key to avoiding swelling in your child’s mouth. Here are some practical tips:

  • Daily oral hygiene: Encourage the child to brush twice a day.
  • Regular visits to the paediatric dentist: Preventive checks every six months help detect problems early.
  • Balanced diet: A low-sugar diet helps maintain healthy teeth.
  • Protection from injury: Use sports mouthguards.

9. The importance of early care for swelling

Frequently Asked Questions

How urgently should I visit the paediatric dentist?

It is very urgent. If the swelling is accompanied by pain, fever or discharge of pus, you must call us IMMEDIATELY, as the infection can spread quickly.

Is swelling normal when new teeth are erupting?

Yes, mild local swelling is common. However, if the cheek is swollen or the child has a fever, this is not caused by eruption and needs to be examined.

Should I apply heat or cold?

ONLY COLD externally on the cheek. Heat, such as a hot-water bottle, is strictly prohibited in cases of inflammation because it helps bacteria multiply.

What if the abscess bursts by itself?

If you see pus in the mouth, rinse with lukewarm water. Relief will be immediate, but the problem remains. You must come to the practice for cleaning and treatment.

Can the swelling go away on its own?

Almost never when it is caused by a tooth. Without treatment—antibiotics or dental intervention—the infection will return more severely.
