The lips are among the most delicate parts of the body.

The outer skin layer of the lips is thinner than the rest of the body.
A bump, exposure to an allergen or an irritant can cause a swollen lip.


Causes of swollen lips

The most common causes of swollen lips are:
1. Allergy is a frequent cause of swollen lips, especially in children and newborns.

  • Allergy to latex. Direct contact with latex can irritate the skin and cause swelling, itching, or rash .
    Contact can happen through balloons, some children’s toys or gloves.
  • Allergy to penicillin  contained in  antibiotics .
  • Food allergy  to eggs, fish, crustaceans, fruits in shell, oils, soy or milk.
  • Allergy to cosmetics may be due to some types of lip gloss, lipstick, lip balm.
  • The insect bite (mosquito, wasp ) can cause a sudden allergic reaction .

Some people have swollen lips when they wake up in the morning due to an allergic reaction, so it is necessary to investigate the cause.

2. Blow or injury

  • Anyone who has suffered a trauma to the lips or face (eg, an elbow or a fist) may develop swelling.
  • The hair removal is another cause of swelling and redness on the lips.
  • Rarely a bite on the lip can cause swelling, but in some cases it causes a skin lesion and a cold sore inside the lips.

3. Lips burned or cracked
A sunburn on the face and lips can cause lip edema.

Cracked lips can cause swelling.
The main causes of cracks are:

  • Wetting or overly licking lips,
  • Or windy, arid, dry climate,
  • Too much sun.

4. Nutritional deficiency
Sometimes swollen lips can be caused by nutritional deficiencies, especially deficiency of B vitamins. If the corners of the lips are swollen and have small cuts, it is possible that the person is deficient in vitamins.

5. Herpes labialis
The  herpes labialis is a viral infection which causes the formation of blisters filled with liquid.
The blisters may be around or on the lips.
Cold sores are caused by the herpes simplex virus  type 1.
If the person suffers from this disease, the lips will become inflamed and even slight pressure causes mild or moderate pain.

6. Other causes

  • The angioedema is a swelling that can be caused by an allergic reaction to a food, pollen, medications or insect bites, but often the cause is unknown.
    May cause swelling:

    • In the face,
    • In the language,
    • On the lips.
  • Infection . Fungal, bacterial, or viral infections can cause swollen lips. If the lips are cracked, infections can reach them through the openings.
  • Pregnancy , pregnant women suffer from fluid retention that can cause lip balm.
  • Heart failure and kidney failure , patients with these disorders suffer from generalized edema (swelling in various parts of the body).


Sudden swelling of the upper lip

If sudden swelling of the upper lip occurs, the most likely causes are:

  • Insect bites,
  • Food allergy.

To reduce swelling, wrap some ice cubes in a paper or cloth napkin and press against the lip at 20-minute intervals. If the swelling does not go away within two days, you should see a doctor.


Lips bumps at night

Swollen, sore lips can be caused by hives from an allergy.
When it occurs overnight, the allergy may be due to:

  • Pillow feathers,
  • Detergent used to wash the sheets.

During sleep, the person may suffer minor trauma to the lips such as:

  • Involuntary bites,
  • Friction (rubbing) against the pillow.

Another cause may be a condition called idiopathic angioedema.


Swollen lip after dentist anesthesia

The local anesthetic does not block all nerve transmissions, only those painful ones. It is like a very strong analgesic applied locally, so the person can still feel:

  • Frio,
  • Hot,
  • Pressure,
  • Tingling.

Is it possible to have swollen lips because of the injection?
Swelling from an injection is very rare, so it’s best to talk to the dentist.

There are several causes of lip inflammation, including:

  • An allergy to latex from gloves used by the dentist.
    That would explain why the lips are swollen.
  • A reaction to one of the components used in the material used for dental intervention.
    Some materials on the lips can cause a burning sensation , but certainly do not cause swelling of both lips.
  • Allergy to   local anesthesia (rare).


  • How long does it take to heal? When does it pass?
    The sensation of swollen, numb lips depends on the amount of anesthetic used, but usually only lasts a few hours.


Symptoms that accompany swollen lips

Usually the swollen lip occurs in conjunction with other symptoms, depending on the underlying disease, for example:

  • Reduced sensitivity,
  • Feeling of heat.

Lips swollen by infection
Swelling of the lips due to infection can occur with:

Swollen lip caused by cold sores

  • Bubbles or bubbles;
  • Cracked lips;
  • Wounds on the skin or lumps of pus.

Lips swollen by trauma

  • Changes in the color of the lips that may turn purple;
  • Pain.
