Bitten Lip - Understanding the Symptoms, Risks, and Treatments

Biting your lip can seem minor, but it can lead to more significant issues if not properly addressed. This comprehensive guide will explore the symptoms, risks, and effective treatments for infected bitten lips, ensuring you have all the information you need to promote healing and prevent further complications. Read on to find out answers to these questions lingering in your mind: “What to do when you bite your lip?” or “How long does a lip bite take to heal?”.

Bitten Lip – Symptoms and Risks

It's usually obvious when you bite your lip, but the injury's severity can vary. Here are some common symptoms and risks associated with a bitten lip:

Immediate Symptoms:

  • Sudden pain at the site of the bite

  • Local swelling

  • Bleeding

  • Redness

  • Sensitivity

Potential Complications:

  • Cuts or abrasions on the bit lip

  • Bumps or bruises

  • Canker sores (small, painful sores inside the mouth)

  • Mucocele (a fluid-filled bump caused by a blocked salivary gland)

While most bitten lips heal within a week or two, some cases can become more severe and require medical attention. If you experience any of the following, it's essential to seek professional help:

  • Deep or large wounds

  • Biting through the entire lip

  • Debris stuck in the wound

  • Worsening pain over time

  • Difficulty opening or closing your mouth

Treating a Bitten Lip

Prompt and proper treatment can promote faster healing and prevent infection. Here are some effective steps you can take to care for a bitten lip:

Clean and Dress the Wound:

  • Use an antiseptic mouthwash containing alcohol or a warm saltwater rinse (mix 1 teaspoon of salt in 8 oz. of water) to clean the wound.

  • Once cleaned, apply a small piece of gauze, tissue, or soft cloth between your lip and teeth to apply pressure and prevent further bleeding.

  • If unable to dress the wound, clean it more frequently to keep it free from bacteria.

Apply a Cold Compress:

  • After the wound stops bleeding, apply a cold compress to your lip to reduce swelling and discomfort.

  • A swollen lip can be hazardous as it may lead to further biting and injury.

Over-the-Counter Pain Relief:

  • Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, aspirin, or naproxen can help alleviate pain and discomfort.

  • If the cold compress provides relief, you can continue using it as needed.

Oral Anti-Septic Gel:

  • Using an over-the-counter oral anti-septic gel can help prevent infection and promote faster healing.

  • Avoid using Polysporin or similar products inside the mouth, as they are not safe for ingestion.

Bitten Cheek or Tongue

If you've bitten your cheek or tongue, the treatment approach is similar to a bitten lip. However, if you've bitten your cheek, it's essential to check for any broken teeth that may have caused the injury.

Canker Sores

Canker sores are small, uncomfortable bumps that can develop inside the mouth, often as a result of biting the inside of the lip or cheek. They may appear round or oval-shaped and can be red or white. While the exact cause is unknown, canker sores can be triggered by:

  • Mouth injuries (like biting the lip or cheek)

  • Viral infections

  • Stress

  • Vitamin or mineral deficiencies

  • Food allergies

  • Hormonal changes

The treatment methods for canker sores are similar to those used for bitten lips, including saltwater rinses, antiseptic mouth rinses, cold compresses, NSAIDs for pain relief, and topical oral pain medications applied directly to the sore.

Identifying the Causes of Lip Biting

While lip biting can often be accidental, several underlying factors may contribute to this habit:

  • Stress and Anxiety: Many people unconsciously bite their lips as a coping mechanism for stress or anxiety. This nervous habit can become ingrained and lead to chronic lip biting.

  • Dry Lips: Dry, cracked lips are more prone to being bitten, as the rough texture can be tempting to peel or bite off. Ensure you keep your lips moisturized with lip balm to prevent this.

  • Teeth Misalignment: If your teeth are not properly aligned, it can increase the likelihood of accidentally biting your lips during eating, speaking, or other activities.

  • Medications: Certain medications, such as those used to treat depression or anxiety, can cause dry mouth or increase the risk of lip biting as a side effect.

  • Nutritional Deficiencies: Deficiencies in certain vitamins and minerals, such as iron, zinc, or vitamins B and C, can weaken the skin and make it more susceptible to injury, including lip biting.

Identifying and addressing the underlying cause can help break the cycle of lip biting and prevent further injury.

Complications of Severe Lip Biting

While most bitten lips heal within a week or two, severe or chronic lip biting can lead to more serious complications, including:

  • Infection: If the bitten lip is not properly cleaned and treated, it can become infected, leading to increased swelling, pain, and the potential for the infection to spread to other parts of the body.

  • Scarring: Repeated or severe lip biting can cause permanent scarring, which can affect the appearance and function of the lips.

  • Oral Thrush: In some cases, a bitten lip can lead to the development of oral thrush, a fungal infection that causes white patches in the mouth and throat.

  • Lip Disfigurement: In extreme cases, chronic or severe lip biting can cause permanent disfigurement or deformity of the lips, which may require surgical intervention to correct.

  • Dental Issues: Excessive lip biting can also lead to dental problems, such as tooth damage, gum recession, or jaw disorders, due to the constant pressure and trauma on the teeth and surrounding structures.

Seeking professional medical or dental attention is essential if you experience any of these complications or if the bitten lip does not heal properly within a reasonable timeframe.

Preventing Lip Biting in Children

Lip biting can be a common habit in children, and it's important to address it early to prevent further complications. Here are some tips for preventing lip biting in children:

  • Identify and Address the Cause: Try to identify the underlying reason for your child's lip biting, such as stress, anxiety, or boredom, and address it appropriately.

  • Provide Distractions: Offer your child alternative activities or toys to keep their hands and mouths occupied, such as stress balls, fidget toys, or chewing gum (for older children).

  • Positive Reinforcement: Praise and reward your child when they refrain from lip biting, as positive reinforcement can help break the habit.

  • Moisturize Lips: Keep your child's lips moisturized with lip balm to prevent dryness and cracking, which can exacerbate lip biting.

  • Seek Professional Help: If your child's lip biting is severe or persists despite your efforts, consider seeking professional help from a pediatrician, dentist, or child psychologist.

By addressing lip biting early and providing the necessary support and guidance, you can help your child break this habit and prevent potential complications.

Preventing Bitten Lips

While accidents can happen, there are some preventive measures you can take to reduce the risk of biting your lip:

  • Be mindful while eating or speaking, and avoid activities that may increase the likelihood of biting your lip.

  • If you have a habit of biting your lips due to stress or anxiety, try using lip balm or carrying a stress ball to occupy your mouth and hands.

  • Maintain good oral hygiene and visit your dentist regularly to identify and address any potential dental issues that could contribute to lip biting.

Nutritional Support for Lip Healing

Proper nutrition can play a crucial role in supporting the healing process of a bitten lip. Certain vitamins and minerals are essential for wound healing and tissue repair:

  • Vitamin C: This powerful antioxidant is crucial for collagen production, which is necessary for wound healing and tissue repair.

  • Zinc: Zinc is essential for cell growth and immune function, both of which are vital for healing.

  • Vitamin A: This vitamin supports the growth and repair of epithelial tissues, which includes the skin and mucosal linings of the mouth.

  • Protein: Adequate protein intake is necessary for the production of new cells and tissues during the healing process.

  • Vitamin E: This antioxidant vitamin helps to protect cells from damage and supports the healing process.

  • Iron: Iron is essential for the production of new red blood cells, which carry oxygen to the wound site to support healing.

Incorporating foods rich in these nutrients, such as citrus fruits, leafy greens, lean proteins, nuts, and seeds, can help promote faster healing and recovery from a bitten lip.

By combining proper wound care, medication management (if necessary), and a nutrient-rich diet, you can support the body's natural healing process and minimize the risk of complications from a bitten lip.


Biting your lip may seem like a minor issue, but it can lead to significant discomfort and complications if not properly addressed. By following the guidelines outlined in this guide, you can effectively treat a bitten lip, promote healing, and prevent further injury. Remember, if the wound is severe or persists for an extended period, it's essential to seek professional medical or dental attention to ensure proper treatment and avoid any potential complications.
