Lip issues


I accidentally bit my lower lip, and now that it's healing, it feels like there's a white lump forming instead of a smooth surface.
It's quite bothersome.
Could you please explain why this is happening and how I can help it heal? Thank you, doctor.

It is recommended that you visit a nearby hospital or clinic with a dermatology specialty for more accurate information.

More Info


When it comes to healing wounds, particularly in sensitive areas like the lips, it's common to experience various changes in the appearance and texture of the skin as it heals. The white bump you are noticing on your lower lip is likely a result of the healing process, which can include the formation of granulation tissue, a natural part of wound healing.

Granulation tissue is a new connective tissue and microscopic blood vessels that form on the surface of a wound during the healing process. It is typically red or pink and may appear slightly raised or bumpy. In some cases, as the tissue matures, it can take on a whitish appearance, especially if there is a buildup of keratin or other cellular debris. This is generally a normal part of healing and should gradually resolve as the tissue continues to mature and remodel.

Here are some important points to consider regarding your situation:
1. Healing Process: The healing process can take time, and the appearance of the wound can change significantly over several weeks. Initially, the area may look swollen or raised, and it may feel different than the surrounding skin. As healing progresses, the tissue should flatten and become more similar in texture to the surrounding skin.

2. Avoid Picking or Manipulating the Area: It's crucial to avoid picking at or manipulating the white bump. Doing so can introduce bacteria into the wound, leading to infection, and may also disrupt the healing process, potentially resulting in scarring.

3. Moisture and Protection: Keeping the area moisturized can help promote healing. You might consider using a gentle, fragrance-free lip balm or ointment to keep the area hydrated. This can also help prevent cracking and further irritation.

4. Signs of Infection: While the white bump is likely a normal part of healing, you should monitor the area for any signs of infection. These can include increased redness, swelling, warmth, pain, or discharge that is yellow or green. If you notice any of these symptoms, it is important to seek medical attention.

5. Consult a Healthcare Professional: If the white bump persists for an extended period or if you have concerns about the healing process, it is advisable to consult a healthcare professional. They can assess the area and determine if any further treatment is necessary.

6. Timeframe for Healing: Healing times can vary based on the severity of the injury, individual health factors, and the care provided during the healing process. Generally, minor injuries to the lips can take anywhere from a few days to a couple of weeks to heal completely.

In summary, the white bump you are experiencing on your lower lip is likely a normal part of the healing process. It is essential to be patient and allow your body to heal naturally while taking care to protect the area. If you have any concerns or if the situation does not improve, do not hesitate to reach out to a healthcare provider for further evaluation and guidance.
