Cuts in Mouth: Causes, Treatment, and Prevention

Whenever we have a complicated meal, engage in sports, or even have minor accidents, the potential for sustaining a cut in mouth is always there. Although these incidents might seem minor, they can rapidly evolve into painful, unbearable, and possibly dangerous situations if not immediately addressed.

This blog post aims to bring light to the causes, preventive measures, and optimal treatment strategies for dealing with these seemingly small but potentially troublesome mouth cuts.

What Causes Cuts in the Mouth?


Mouth Injury

The most common culprit of cuts in the mouth is physical injury. This injury can be due to accidental bites during your meals, facial injuries sustained during sports without wearing a mouth guard, or sharp edges from a broken tooth. Always ensure you are cautious during activities involving mouth movements.

Spicy, Hot, and Sharp Foods

Hot and spicy foods may cause sores and cuts in your mouth. An ill-fated bite on a crispy tortilla chip could result in a cut, and extremely hot food or beverages could burn your soft tissue, leading to sores. Engaging in mindful eating practices can minimize these risks.

Facial Wounds

Facial wounds penetrating the mouth area can also result in cuts. These might include, for instance, accidents while shaving or an unfortunate fall. Always be careful and consider your safety first in all you do.

Oral Health Issues

Oral health conditions such as mouth ulcers, gum disease, or an oral lesion due to mouth cancer can lead to mouth sores or cuts. Paying attention to changes like if a cut inside the mouth turned white and seeking immediate medical care if any abnormal signs appear is vital. Regular dental check-ups can also help in early detection.

Quick and Accidental Bites

For small children still learning to eat, the chance of inflicting a bite on themselves accidentally is high. These bites result in a cut inside the mouth, which may appear white. Training your child to eat gently and providing soft foods can help minimize such incidents.

How Can You Treat Cuts in Mouth?


Step 1: Clean the Area

One of the initial and important steps to heal a cut in the mouth is to cleanse the area with warm water. This helps to remove any dirt particles stuck in the wound, which might affect healing. Take half a teaspoon of salt and dissolve it in a glass of lukewarm water. Swish the solution around your mouth for 30 seconds before spitting it out. This should be done about 3-4 times daily to maintain oral hygiene and prevent bacterial infections.

Step 2: Apply a Cold Compress

To initiate the healing process of a cut in your mouth, you can create a simple yet effective cold compress using a clean cloth wrapped around a few ice cubes. Applying this makeshift cold compress to the injured spot can help constrict the blood vessels to reduce swelling and numb the mouth pain—two critical steps to heal a cut in your mouth. Maintain the cold compress against the cut for about 15 minutes.

Step 3: Use Over-the-Counter Solutions

Over-the-counter treatments can fasten the healing process of a cut in the mouth. Oral gels and ointments can offer minor treatment by numbing the area and reducing pain. Remember to follow the instructions on the packaging for effective results.

Step 4: Eat Soft Foods

In the normal circumstances of having a cut in your mouth, avoiding foods that can worsen the mouth pain is often beneficial—particularly hard, sharp, or spicy foods. Opt for soft, easy-to-eat foods like yogurt or mashed potatoes until the cut begins healing.

Step 5: Stay Hydrated

Ensure you drink plenty of water; this aids in keeping the area clean and helps speed up the healing process. Avoid hot or acidic drinks as they can cause further irritation to the cut.

Step 6: Take Over-the-Counter Pain Reliever

Under severe bleeding or discomfort, over-the-counter pain relievers can manage the pain from the cut. These include aspirin, ibuprofen, or paracetamol. Always follow the recommended dose on the packaging.

Step 7: Continue With Oral Hygiene

Good oral hygiene protects your mouth from fungal infections, cold sores and further complications. Hence, keep brushing your teeth twice daily and consider using a mouthwash to keep your mouth clean and fresh.

Step 8: Seek Medical Attention

For cuts resulting from a human bite, rusty objects, or showing signs of infection, it’s essential to get immediate medical attention. Healthcare professionals can provide a tetanus shot if needed and can provide the best advice and treatment for cuts.

Mouth injuries in children should always be referred to a pediatrician. If cuts are deep and excessively bleeding, they might have hit a rich blood supply and might require stitches to help control the bleeding and healing.

What Should You Avoid When You Have A Cut in Your Mouth?


  • Alcohol and Tobacco. If you have an infected cut in your mouth, you might want to hold off on the alcohol and tobacco intake. These substances can interfere with your mouth’s healing progress by slowing blood clotting and prolonging inflammation. They also increase your risk for further infections.
  • Avoid Hot Food and Drinks. Hot food and beverages can inflict more harm than good when nursing a mouth cut. High temperatures can irritate soft tissue and deter the healing process. Dentists recommend lukewarm or cool food and beverages that soothe the damaged area.
  • Acidic Foods. Acidic foods like citrus fruits can increase the discomfort and pain around the mouth cut. Plus, they may spark inflammation and slow the healing period. Swapping acidic foods with mild, non-acidic alternatives is a good idea during this period.
  • Hard or Sharp Foods. Hard, crunchy, or sharp-edged food might be tasty, but it can be dangerous for a mouth cut. Their rough texture can cause more damage to the soft tissue and hinder the healing process. Instead, opt for soft foods that require minimal chewing to ensure you don’t worsen your oral wound.

How Can You Prevent Cuts in Your Mouth?


1. Mouth Guard for Sports Activities

If you participate in sports that may potentially result in a mouth injury, it is recommended to use a mouth guard. This precaution can prevent many unnecessary mouth cuts.

2. Soft Foods

If you’ve experienced a recent mouth injury, it’s best to stick to a diet of soft foods until your cut has fully healed. This will help avoid annoying and potentially worsening the wound.

3. Avoid Hot Foods and Spicy Foods

Both spicy and hot foods can irritate cuts and sores in your mouth. Allow your food to cool down before eating, and limit your intake of spicy meals to foster faster healing.

4. Good Oral Health

Good oral health can help prevent many oral conditions that lead to mouth cuts and sores. Regular dental check-ups, proper hygiene, and taking care of your oral tools play a significant role in oral health.

5. Proper Diet

Eating a healthy, nutrient-rich diet helps strengthen your immune system, which plays a crucial role in preventing and fighting infections. Strong, healthy oral tissues are less likely to be damaged, reducing the risk of oral health problems.
