Dealing with a Biting Injury: What to Do When You Bite Your Tongue - Otolaryngology

When you accidentally bite your tongue, it can be quite painful and lead to the formation of a blood blister or a small sore. In your case, it sounds like you have developed a small blood blister on the underside of your tongue after biting it while eating guava. This is a common injury and usually heals on its own, but there are some steps you can take to promote healing and alleviate discomfort.

First and foremost, it's important to keep the area clean. Rinse your mouth gently with warm salt water several times a day. This can help reduce the risk of infection and promote healing. Avoid using mouthwash that contains alcohol, as it can irritate the sore and delay healing.

As for the blood blister itself, it is generally best to leave it alone. Breaking the blister can lead to increased pain and a higher risk of infection. The body will typically reabsorb the fluid in the blister, and the tissue will heal naturally over time. If the blister does not cause significant pain or discomfort, it is advisable to avoid any aggressive treatment.

If you find that the pain is bothersome, you may consider applying a topical oral gel or ointment that is designed for mouth sores. These products can provide a protective barrier over the sore and help reduce pain. However, be cautious and ensure that any product you use is safe for oral use.

In terms of when to seek further medical attention, if the blister does not improve within a week, or if you notice any signs of infection (such as increased redness, swelling, or pus), it would be wise to consult a healthcare professional. While an ear, nose, and throat (ENT) specialist can certainly help with oral injuries, a dentist or oral surgeon would also be well-equipped to address issues related to the tongue and mouth.

In summary, here are some steps you can take to manage your tongue injury:
1. Keep it clean: Rinse your mouth with warm salt water to help prevent infection.

2. Avoid irritation: Try not to touch or irritate the blister. Eating soft foods and avoiding spicy or acidic foods can help minimize discomfort.

3. Use topical treatments: If necessary, apply a topical oral gel to relieve pain and protect the area.

4. Monitor for infection: Watch for signs of infection and seek medical attention if the blister does not heal or worsens over time.

In most cases, minor tongue injuries like this will heal on their own without complications. However, if you have any concerns or if the injury seems severe, don't hesitate to reach out to a healthcare provider for personalized advice.
