Gum Injuries: Healing Tips and Care for Your Oral Health - Dentistry

Gum ulcer


Hello Doctor: I'm not sure if it's because I've been brushing too hard or for some other reason, but this morning I noticed that the gum above one of my teeth is injured and has a hole in it, similar to a sore on my lip, with a whitish appearance.
Will this heal on its own? Should I continue to brush my teeth as usual, or should I avoid the sore? I'm worried that not brushing that area will lead to gum inflammation, but I'm also concerned that brushing might make the wound worse.
What should I do?

Dr. Zhuang Suhui reply Dentistry


If the wound is caused by brushing too hard, it will typically heal on its own in about a week.
You can continue to brush your teeth as usual, but be sure to avoid the wound.
If the toothbrush cannot avoid the wound, you can use gauze to clean the teeth around the wound.
Brushing directly over the wound may prevent it from healing properly.

When dealing with gum injuries, such as the one you've described, it's essential to approach the situation with care and a proper understanding of oral health. Gum injuries can occur for various reasons, including aggressive brushing, trauma from food, or even underlying dental issues. In your case, it seems that you have a small wound on your gum that resembles a canker sore, which can be quite painful and concerning.

Firstly, it's important to note that small gum injuries often heal on their own, given the right conditions. The oral mucosa has a remarkable ability to regenerate, and minor abrasions or cuts typically resolve within a week or two. However, there are several steps you can take to facilitate healing and prevent further complications.

1. Oral Hygiene: Maintaining good oral hygiene is crucial, even when you have a gum injury. You should continue to brush your teeth, but do so gently around the affected area. Use a soft-bristled toothbrush to minimize irritation. Avoid aggressive brushing, as this can exacerbate the injury and delay healing. Instead, focus on brushing the other teeth and gently cleaning around the injured gum.

2. Rinsing: Consider using a mild saltwater rinse to help keep the area clean. Mix about half a teaspoon of salt in a cup of warm water and gently swish it around your mouth, especially near the injury. This can help reduce inflammation and promote healing. Avoid using mouthwashes that contain alcohol, as they can irritate the wound further.

3. Dietary Considerations: While your gum is healing, try to avoid hard, crunchy, or spicy foods that could irritate the injury. Soft foods are less likely to cause discomfort and can help you maintain a balanced diet during the healing process.

4. Pain Management: If the injury is painful, over-the-counter pain relievers such as ibuprofen or acetaminophen can help alleviate discomfort. However, always follow the recommended dosage and consult with a healthcare professional if you have any concerns.

5. Monitoring the Injury: Keep an eye on the injury for signs of infection, such as increased redness, swelling, pus, or persistent pain. If the wound does not show signs of improvement within a week or if you notice any concerning symptoms, it’s advisable to consult a dentist for further evaluation.

6. Avoiding Irritants: Try to avoid tobacco products and limit alcohol consumption, as these can irritate the gums and hinder the healing process.

7. Professional Care: If the injury is severe, or if you have underlying dental issues that may have contributed to the injury, it’s essential to seek professional dental care. A dentist can provide a thorough examination and recommend appropriate treatment, which may include topical medications or other interventions.

In summary, while your gum injury may heal naturally, taking proactive steps to maintain oral hygiene and monitor the injury is crucial. Gentle brushing, saltwater rinses, and avoiding irritants can significantly aid in the healing process. If you have any doubts or if the condition worsens, don’t hesitate to reach out to a dental professional for guidance. Your oral health is vital, and addressing issues promptly can prevent more significant problems down the line.
