There are many treatment options available to provide immediate care and relief from the pain. Let’s check out how lip injury can affect oral health and how can you treat it.

What is a lip injury?

Lip injuries are described as a cut or a split in the lip that creates an open wound due to the disjunction between the tissues, accompanied by bleeding and pain.

The upper lip is frequently affected first. A most common cause of lip injury in sports that are played vigorously, such as football, cricket, and hockey.

Most often children who are involved in such sports are affected by lip injury.

Although precautionary measures like mouth guards and helmets can help to some extent, lip injuries can be easily treated and healed with proper care. (1)

What are the types of lip injury?

Lip injury can occur in any individual who plays high contact sports. But it is commonly seen in children especially the teenagers between 15-18 years of age.

Typically, the lip is made up of three layers of soft tissues which are the skin that forms the outer layer of the lip, muscle and the oral mucosa which lines the inner surface of the mouth.

Based on the depth of the cut and the tissue involved, lip injuries can be divided into two types –

Split in the skin

A superficial cut in the surface of the lip is the easiest and the quickest lip injury to heal. The lip receives an abundant supply of blood from the vast network of blood vessels present beneath it.

Hence, a cut in the lip causes a significant amount of bleeding which can be stopped by applying quick compressions for at least 5 -10 minutes.

Mucosal lacerations

A severe form of lip injury is mucosal laceration which occurs on the internal surface of the mouth.

A mucosal tear usually creates a flap which interferes while chewing and speaking. It is the most dangerous form of lip injury as it attracts food particles and makes the area difficult to clean.

Lacerations more than two centimeters may require advanced treatment and care. (2)

What are the sign and symptoms?

Common signs and symptoms may include –

  • A split in the tissue
  • Pain or numbness in the affected area
  • Swollen lip – sometimes a swelling hides the underlying injury may need clinical attention
  • Bruising, i.e., internal bleeding which appears as a blue patch on the lip. Bruising is self-healing and subsides in a couple of weeks.
  • Difficulty in chewing food or speaking in case of mucosal lacerations

What effect does the lip injury have on your oral health?

A lip injury can adversely affect oral health in several ways –

  • It can minimize the ability of the mouth to open or close
  • In some cases, it may alter the structure of your teeth
  • Mucosal lacerations become a prime area of oral infection because of food trapping
  • If the source of lip injury was a blow from a ball, it could impact the teeth by chipping or knocking it out and may also produce a puncture wound on the lip
  • The mouth with a lip injury becomes more susceptible to oral infection due to a continuous build-up of plaque and bacteria

How can a lip injury be treated?

The treatment of a lip injury depends on the depth and severity of the wound.

  • In case of a superficial cut or abrasion, which only involves a layer of the skin, you can treat it yourself by washing the area with an antiseptic soap and gently wiping it with a clean cloth.
  • For minor mucosal injuries, you can either use salt water or a 1:1 mixture of hydrogen peroxide and water to rinse the mouth thoroughly. Be careful not to swallow the mixture.
  • Professional treatment may be required when the injury shows signs of swelling, deep lacerations, puncture wounds or infections. Antibiotics treat such wounds and sutured after cleaning them. A dentist may help to detect any effects on the teeth and provide the appropriate treatment. (3)

Home care tips

Lip injuries are the quickest to heal when appropriately cared. You can follow these simple tips to allow faster healing of the wound.

  • During the process of healing, it is essential to maintain cleanliness around the wound. An antiseptic mouthwash can help to maintain hygiene and prevent unnecessary complications like the formation of ulcers and infections
  • Avoid straining of your muscles in the mouth
  • Avoid eating hot, spicy and acidic food till the wound heals completely
  • Brush and floss daily to maintain the health of your teeth

Take away message
