There is nothing quite like it. You're trying to enjoy a meal or just talk, and you feel that sharp, nagging pain inside your mouth. You have one of those awful canker sores again, and it is making your life miserable. That tiny little sore can cause a surprising amount of trouble, but if you're tired of dealing with these painful sores, you have come to the right place.
What Exactly Are Canker Sores?
Canker sores are small, shallow lesions that develop on the soft tissues inside your mouth. They can show up on your tongue, inside your cheeks or lips, or at the base of your gums. The good news is that canker sores aren't contagious, so you cannot spread them to other people.
The medical name for them is aphthous stomatitis. It is important to know that they are completely different from cold sores. Cold sores, or fever blisters, are caused by the herpes simplex virus and appear on the outside of your mouth, usually on the lips, while canker sores stay inside your mouth.
While the single cause for every sore is not fully understood, they are a very common issue that most people experience at some point. It's common to get them a few times a year. Understanding them is the first step toward finding relief.
What Do They Look and Feel Like?
Usually, you can feel a canker sore coming before you can even see it. You might notice a tingling or burning sensation a day or two before the sore appears. This early warning sign lets you know that trouble is on its way.
When it finally shows up, a typical canker sore is round or oval shaped. Common symptoms include a white or yellowish center with a distinct red border around it. The pain can feel sharp and localized, making eating and talking uncomfortable.
These painful sores love to pop up in the most inconvenient places. You can find them under your tongue, along the inside of your cheeks, and on your inner lip. This placement is what makes eating acidic or spicy foods so difficult when you have one.
The Main Types of Canker Sores
Not all canker sores are created equal. They generally fall into one of three categories, based mostly on their size and how long they stick around. Understanding the type you have can help you know what to expect and what canker sore treatment might be effective.
Minor Canker Sores
This is the most common type you will encounter, often referred to as a minor canker. These minor canker sores are usually small, less than one centimeter in diameter. They often appear on their own but sometimes show up in small groups of two or three.
The good news about minor sores is that they tend to heal relatively quickly. According to information from the Merck Manual, they typically heal within one to two weeks. Best of all, they usually do not leave any scars behind.
Major Canker Sores
Major canker sores are less common, and they are the ones you really want to avoid. They are larger, deeper, and more roundly defined than their minor cousins. The pain from these sores can be extremely painful and much more intense as well.
Because major canker sores are larger and more severe, they take a lot longer to heal. You could be dealing with one for up to six weeks. Unfortunately, they can sometimes leave a scar inside your mouth once they finally go away.
Herpetiform Canker Sores
The herpetiform canker type is quite rare. Despite the name herpetiform, herpetiform canker sores are not caused by the herpes virus. This type is named for its appearance, which can look like a herpes infection.
They appear as clusters of ten to one hundred tiny, pinpoint-sized sores. These clusters can merge into one large, irregular ulcer. Herpetiform canker sores usually heal in about one or two weeks without leaving any scars.
So, What Causes These Painful Sores?
This is the big question everyone has about canker sores. The frustrating answer is that doctors don't know for certain what causes every case. However, research from institutions like the Cleveland Clinic points to many different triggers and risk factors that can lead to an outbreak of canker sores.
For many people, the sores are a bit of a mystery. One day you are fine, and the next you have a painful spot in your mouth. Let's look at some of the most common suspects behind these sores.
- Mouth Injuries: A simple, accidental cheek bite can be enough to start a sore. So can aggressive tooth brushing, a slip of the toothbrush, or irritation from dental work like braces or ill-fitting dentures.
- Certain Foods: Some foods are well-known culprits. This is especially true for acidic foods like citrus fruits, pineapple, and tomatoes. Other triggers can include spicy foods, chocolate, coffee, strawberries, and nuts.
- Emotional Stress: Life can get stressful, and sometimes our bodies react in strange ways. The connection between stress and canker sores has been studied, showing a clear link for many individuals. Implementing stress reduction techniques may help some people.
- Nutritional Deficiencies: Not getting enough of certain vitamins and minerals might be a problem. Low levels of vitamin B12, iron, zinc, or folic acid are associated with canker sores. A nutritional deficiency can weaken the tissues in the mouth.
- Toothpaste Ingredients: Some people find that toothpastes containing sodium lauryl sulfate (SLS) can cause canker sores. This is a foaming agent found in many oral hygiene products that can strip away the protective lining of the mouth.
- Hormonal Shifts: For some women, canker sores seem to appear at certain times during their menstrual cycle. This points to hormonal changes being a possible trigger for aphthous stomatitis.
- Health Conditions: Sometimes, frequent canker sores can be a sign of a larger issue. Conditions like celiac disease, inflammatory bowel diseases like Crohn's, and autoimmune disorders can all cause these ulcers by affecting the immune system.
How to Get Rid of Canker Sores Faster
Waiting for a canker sore to heal on its own can feel like a lifetime. While there is no magic cure that zaps them instantly, there are many things you can do for sore treatment. These tips can help soothe the pain and may speed healing.
Most of these remedies use simple items you probably already have at home. The goal is to reduce pain, minimize irritation, and keep the area clean. A combination of approaches often works best to ease pain and discomfort.
- Use a Salt Water Rinse: This is a classic remedy for a reason. Dissolve a teaspoon of salt in a half cup of warm water, swish it around in your mouth for 30 seconds, and then spit it out. This simple mouth rinse can be used a few times a day to clean the area and promote healing.
- Try a Baking Soda Paste: Mix a small amount of baking soda with water to form a thick paste. Gently apply it to the sore with a clean finger or a cotton swab. This can help neutralize acids from food and reduce inflammation.
- Dab on Milk of Magnesia: A small amount of milk of magnesia applied directly to the sore a few times a day can offer relief. It acts as an acid neutralizer and can coat the sore to reduce irritation from food and talking.
- Watch What You Eat: Stay away from foods that are acidic, spicy, or crunchy. Foods including acidic fruits can really irritate the sore and make the pain much worse. Stick to softer, blander foods until it heals completely.
- Use Over-the-Counter Products: Your local pharmacy has plenty of options for canker sore treatment. Gels and pastes with numbing agents like benzocaine can give temporary pain relief. Some products form a protective barrier over the sore.
- Be Gentle When Brushing: Use a toothbrush with soft bristles to avoid bumping and irritating the sore. A gentle approach to your good oral hygiene routine is important while you are healing. Avoid harsh mouth rinses that contain alcohol.
- Try a Hydrogen Peroxide Rinse: A diluted hydrogen peroxide solution can act as an antiseptic to clean the sore. Mix one part 3% hydrogen peroxide with one part water. Swish for about a minute and then spit it out completely, being careful not to swallow.
- Consider Laser Therapy: For a severe canker sore or recurrent outbreaks, some dentists offer laser therapy. This modern treatment can significantly reduce pain almost immediately and speed healing time. It's a quick procedure done right in the dental office.
Some people also find relief from natural remedies. The Mount Sinai Health System notes that things like licorice root and chamomile have been used traditionally to reduce inflammation, although more research is needed to confirm their effectiveness for canker sores.
When You Should See a Dentist or Doctor
Most canker sores are just a temporary problem that goes away on its own. They are more of an annoyance than a serious health issue. But, there are times when it is a good idea to get a professional opinion from a care provider.
Your dentist or primary care doctor can help diagnose the issue correctly and rule out other, more serious problems. To diagnose canker sores, a care provider will usually perform a simple physical exam. They will look at the sores and ask about your canker sore symptoms and medical history.
In most cases, this is all that is needed to diagnose canker. However, if sores are persistent or severe, your doctor might recommend a blood test to check for nutritional deficiencies or other underlying conditions. It is better to be safe and get it checked out if something feels off.
You should make an appointment for dental care or with your doctor if you experience any of the following:
- Your canker sores are unusually large.
- You have new sores appearing before old ones heal, or the sores are spreading.
- The sores have not healed after two weeks.
- The pain is severe and you cannot control it with home remedies.
- You find it very difficult to eat or drink anything.
- You also have a high fever or feel generally unwell.
These signs could indicate that something more is going on. A medical or dental professional can offer stronger prescription treatments, like medicated mouthwashes or topical steroids, to manage the pain and help you heal. Seeking help is a key part of managing your oral health.
Can Canker Sores Be Prevented?
Wouldn't it be great to stop these sores from showing up at all? While there is no surefire way to prevent canker sores entirely, you can reduce how often you get them. The approach to prevent canker often comes down to avoiding your personal triggers.
If you pay close attention, you might notice a pattern to your outbreaks. Do you always get a sore after eating pineapple? Or when you are feeling particularly stressed at work? Identifying these risk factors is the first step.
Try keeping a simple food and symptom journal for a few weeks to track when sores appear. You might be surprised by what you learn. Taking proactive steps can make a big difference in keeping your mouth comfortable and sore-free, and it is wise to practice good habits.
| Prevention Strategy | What to Do |
|---|---|
| Adjust Your Diet | Avoid foods that you know trigger your sores, especially spicy and acidic items. Eat a balanced diet rich in vitamins. |
| Practice Gentle Oral Care | Use a soft-bristled toothbrush and practice good oral hygiene. Avoid harsh mouthwashes that contain alcohol. |
| Check Your Toothpaste | If you get frequent sores, try switching to a toothpaste that is free of sodium lauryl sulfate (SLS). |
| Manage Your Stress | Find healthy ways to cope with stress, like exercise, meditation, or spending time on a hobby you enjoy. |
| Protect Your Mouth | If you have braces or other dental appliances, ask your orthodontist for wax to cover sharp edges. |
