Bitten Tongue or Cheek? First Aid Tips from an Edmonton Dentist
We’ve all done it—bitten our tongue or cheek while eating, talking, or even during sleep. It’s one of those sudden, painful surprises that can leave your mouth sore, bleeding, or even swollen for hours.
While most cases are minor and heal on their own, some bites can lead to complications like infections, ulcers, or prolonged discomfort. At Dr. Molly Rodgers Dental, we believe knowing what to do immediately can help you heal faster and avoid further issues. In this guide, we’ll share expert first aid tips for dealing with a bitten tongue or cheek and when to contact your dentist for help.
Why Do We Bite Our Tongue or Cheek?
Biting your tongue or cheek can happen in an instant—while eating, talking, or even sleeping. Though usually accidental, it’s often painful and can lead to swelling or infection if not treated.
Common triggers include:
- Eating too quickly
- Talking or laughing while chewing
- Misaligned teeth or orthodontic appliances
- Sleep disorders like bruxism (teeth grinding)
- Accidental trauma during sports or falls
Children, adults with dental issues, or anyone undergoing dental work are more prone to biting injuries.
Step-by-Step First Aid for a Bitten Tongue or Cheek
If you or your child has accidentally bitten the inside of the cheek or tongue, it can be painful and alarming—especially if there’s bleeding or swelling. Fortunately, most of these injuries are minor and can be treated at home. Follow these simple first aid steps to reduce pain, control bleeding, and lower the risk of infection so healing can begin quickly and safely.
Step 1: Stop the Bleeding
Use a clean piece of gauze or a paper towel to apply gentle pressure to the injured area. Most minor oral injuries stop bleeding within a few minutes.
Tip: If the bleeding doesn’t stop after 10–15 minutes of firm pressure, contact a dental professional immediately.
Step 2: Rinse with Salt Water
Mix ½ teaspoon of salt in a cup of warm water and rinse your mouth gently. This helps clean the wound and reduces the risk of infection.
Avoid using mouthwashes with alcohol as they can sting and irritate the area further.
Step 3: Reduce Swelling and Pain
Apply a cold compress to the outside of the mouth, near the injury. You can also suck on ice chips or hold a piece of ice wrapped in a paper towel inside the mouth near the injured area.
Cold reduces inflammation, numbs the area, and minimizes swelling—especially helpful during the first 24 hours.
Step 4: Avoid Further Irritation
While your mouth heals:
- Avoid crunchy, spicy, acidic, or salty foods
- Refrain from chewing gum or hard candies
- Eat soft foods and chew slowly
- Use a soft-bristled toothbrush to clean your teeth
- Avoid talking while eating
This reduces the chance of re-injury and promotes faster healing.
When to See a Dentist for a Bitten Tongue or Cheek
While most bites are mild and heal within 7–10 days, you should contact Dr. Molly Rodgers Dental in Edmonton if you notice any of the following:
- The wound is deep, or a chunk of tissue is missing
- Bleeding won’t stop after 15 minutes of pressure
- There are signs of infection, such as pus, increased redness, fever, or swelling
- The bite is a result of trauma or a fall and may be accompanied by broken teeth
- You experience ongoing pain or difficulty eating and speaking
Common Complications of Biting the Tongue or Cheek
While most tongue or cheek bites are minor and heal without issue, there are cases where complications can develop—especially if the wound isn’t kept clean or continues to be irritated. It’s important to monitor the area and know what to watch for, as some issues may require professional dental care. Though uncommon, the following complications can arise:
1. Infection
Bacteria in the mouth can infect open wounds, especially if the area is not kept clean.
2. Mouth Ulcers or Canker Sores
Continual irritation can lead to painful ulcers that linger for days.
3. Scarring or Tissue Damage
Deep bites can result in scar tissue forming in the cheek or tongue, affecting appearance or comfort.
4. Repetitive Biting from Misaligned Teeth
If you’re frequently biting the same spot, it could be due to dental misalignment or poorly fitted dental work.
Preventing Futur e Bites
To reduce your risk of future mouth injuries:
- Eat slowly and avoid distractions while chewing
- Wear a mouthguard if you grind your teeth at night or play sports
- Address misaligned teeth or dental restorations with your dentist
- Keep up with regular dental visits to catch any structural issues early
Pediatric Tip: What to Do When a Child Bites Their Mouth
Kids often bite their cheeks or tongues accidentally, especially when they’re active or have just received local anesthesia after a dental visit.
Pro Tip: After dental work involving freezing, monitor your child closely. Avoid giving them food until the numbness wears off to prevent self-inflicted bites.
If a child bites their mouth and there’s swelling, bleeding, or trouble eating, it’s always best to consult a dentist.
