Gum Ulcer: Every Potential Cause Explained

Ulcer on Gum: Potential Causes
Have you ever looked in the mirror and noticed an unexpected white or red painful spot on your gums? It may be a gum ulcer.

Even though gums are quite resilient in the mouth, making them less susceptible, they're not invincible.

Whether it's due to infections, injuries, or those annoying canker sores, it's crucial to understand what you're up against to take the right steps.

In this article, we will discuss every possible cause of ulcers on the gums – what causes them, how to recognize them, and most importantly, how to ensure smooth and rapid recovery.

1. Is it a painful single ulcer? It's probably a Canker Sore.

If you've suddenly noticed a painful single sore in your mouth and can't figure out where it came from, there's a good chance it's a canker sore.

Canker sores are quite common and can surprise anyone at least once in their life. Count yourself lucky if this is your first experience because some people have to deal with these annoyances several times a year.

They can pop up anywhere inside your mouth, especially on the inner lips, cheeks, under your tongue, and at the back of your palate (the roof of your mouth).

Interestingly, the gums are less likely to be affected by canker sores. This is because they're covered by a protective layer called keratin. Think of keratin as an armor that makes your gums strong and resistant.

When canker sores do target your gums, they usually go for the nonkeratinized part – that's the base far from your teeth.

Recognizing canker sores is quite simple. They can show up as a single sore or in small groups of up to five. They're surrounded by a red circle and have a whitish or yellowish coating. These sores are usually round and measure just a few millimeters in size.

The exact cause of canker sores is still a bit of a mystery. However, there are a few likely factors that might contribute:

  • Genetics: If others in your family have had these, you might be more prone to them.

  • Nutrition: Your diet could play a role – a lack of certain nutrients might make you more susceptible.

  • Stress: Yep, stress affects your mouth too. When you've been through a rough time, mouth ulcers can appear.

  • Hormones: Hormonal changes can trigger these sores, just like they can affect other things in your body. Canker sores can be associated with hormonal changes.

  • Allergies: Have you eaten anything unusual lately? Your mouth may be sensitive to certain foods like chocolate, tomatoes, nuts, and strawberries.

The 4 Stages of Canker Sores


Canker sores go through four distinct stages as they develop:

Canker sore on the gum stages
  1. The Prodromal Stage: This early phase lasts 24 hours. You might start feeling a tingling or burning sensation in the area where the sore is about to appear.
  2. The Macule Stage: From 18 hours to 3 days, you'll see a red or pink spot in the area involved.
  3. The Ulcer Stage: This is when the actual sore takes center stage. You'll notice a shallow, round ulcer with a whitish or yellowish coating. This is when the pain can be at its peak.
  4. The Healing Stage: Luckily, canker sores do eventually start to heal. In this stage, the sore gets smaller and gradually starts to flatten.

How are Canker Sores Treated?


When it comes to canker sores, no magic cure will make them vanish instantly. But the good news is they tend to heal on their own, usually within about 8 to 10 days, and they typically don't leave any scars behind.

What you can do is help speed up the healing process, manage the pain, and prevent potential infections and future recurrences. There are a few over-the-counter options that can assist you on this journey:

  • Numbing Agents: These can provide instant relief by numbing the sore, making it less painful. One over-the-counter numbing product is Orajel.

  • Mouthrinses: These help keep the area clean, reducing the risk of infection and promoting healing. You can opt for a natural approach with a saltwater rinse multiple times a day or consider using an over-the-counter mouthwash.

  • Topical Corticosteroid Preparations: These are generally available by prescription, rather than over-the-counter. They can help reduce inflammation and discomfort associated with the sore.

Now, the real challenge with canker sores is that they often make a comeback. Understanding what triggers them can be essential in preventing their return. Here are some points to consider:

  • Stress: If you believe stress is causing the issue, it's a good idea to find ways to relax and engage in activities that can help you handle it better.

  • Diet: Think back to what you ate about three days before the sore popped up. Certain foods might have played a role.

  • Nutritional Deficiencies: If you're lacking certain vitamins and minerals in your diet, addressing these deficiencies can help prevent future outbreaks. Supplementation with B12, B9, and iron has been shown to minimize recurrence.

  • Avoid Injury or Trauma: Remove any sources of injury or trauma in your mouth. Sometimes, accidental bites or sharp edges can irritate the sensitive mucous lining.

  • Oral Hygiene: Keeping your mouth clean and addressing any infections, including cavities, can also help prevent canker sores.

2. Traumatic Ulcer: When Accidents Hurt Your Gums

Have you brushed your teeth too vigorously? Or maybe you used too much mouthwash or had something really hot or super acidic to drink?

Well, if you've been a bit tough on your gums, you could end up with what's called a Traumatic Ulcer – a not-so-pleasant reminder of the accident.

These ulcers are basically the result of an injury. They result from the breakdown of the outer protective layers. And here's the thing: where the gum got hurt is exactly where the ulcer appears.

Usually, they show up as whitish or yellowish spots without the red lining seen in canker sores.

The shape of these ulcers isn't as predictable as those canker sores. They're irregular, and how they look depends on the kind of injury they came from.

Treatment of Traumatic Ulcer on the Gum


When it comes to traumatic ulcers, they don't tend to heal on their own unless the source of irritation is taken away.

The primary approach to treatment involves eliminating the root cause. Once the irritant is removed, these ulcers often heal naturally within 8 to 10 days.

It's also crucial to prevent any potential infection that could worsen the situation. Your dentist may recommend using a topical antiseptic cream, mouthwash, or a numbing agent to offer relief.

When Traumatic Ulcers Take a Serious Turn


Traumatic ulcers aren't typically harmful. As mentioned, they tend to heal once you've dealt with the underlying cause.

However, it's important to understand that persistent and long-lasting trauma for months or years can result in serious damage to your mouth tissues. In some cases, they might even contribute to malignant changes that can lead to oral cancer.

So, while they might seem minor, it's wise to address them promptly to avoid potential complications down the road.

3. Multiple Gum Ulcers due to Viral Infection

Did you know that some viruses and bacteria can make their presence felt in your mouth? This is particularly true for certain viral infections like Herpes and HIV.

When it comes to these infections, ulcers often show up in larger numbers and come with additional symptoms such as Fever, Fatigue, and Swollen Lymph Nodes in the neck and under the lower jaw.

These infections can target any part of your mouth, including your gums.

In patients with HIV, mouth ulcers tend to be more severe. They're deeper, more painful, and can grow to several centimeters. What's more, their healing process is slower, and they might leave behind scars.

Now, let's talk about herpes infection. The culprit here is the Herpes simplex virus type 1. It's also known as oral herpes because its primary symptoms show up in the mouth.

Believe it or not, about 67% of people worldwide carry the Herpes simplex virus type 1 infection. But don't fret – in most cases, the virus remains dormant, just hanging out in our bodies without causing any harm.

However, certain conditions like Stress, Fever, a Common Cold, or even Trauma can wake up this dormant virus and trigger symptoms.

It often begins with an itchy or burning sensation, followed by the appearance of clusters of fluid-filled blisters after a day or two. These blisters eventually break, leaving behind multiple ulcers.

What Steps to Take Next?

If you suspect that your mouth ulcers might be the result of a viral infection, it's essential not to wait. Seek assistance from a healthcare professional without delay. Additional tests will be conducted to ascertain whether a virus is indeed the culprit.

When it comes to treating mouth ulcers caused by viral infections, the following steps are typically taken:

  • Prescription of antiviral medication
  • Use of antiseptic mouthwash
  • Adoption of a soft diet
  • Painkillers

4. Necrotizing Ulcerative Gingivitis

While we're familiar with gum disease, have you ever come across the term "Necrotizing Ulcerative Gingivitis"?

This condition is a severe manifestation of gum disease that demands immediate attention due to its aggressive and rapid nature. One of its noticeable indicators is the emergence of ulcers on the gum's triangular area, found between the teeth.

So, what's the story behind necrotizing ulcerative gingivitis? Who's most vulnerable, and how does it relate to gum ulcers?

To start, necrotizing ulcerative gingivitis, or NUG for short, is a rare gum disorder that predominantly affects young individuals with weakened immune systems. It arises from the interplay between oral bacteria and specific external factors that compromise the body's natural defenses. Common triggers for this condition include:

  • Inadequate oral hygiene
  • Stress
  • HIV infection
  • Tobacco use
  • Malnutrition

Once NUG takes hold, it often brings about intense pain, foul breath, and bleeding gums. People might also experience symptoms like fever, fatigue, and swollen lymph nodes. Everyday activities like eating, swallowing, and speaking can become challenging.

The damage inflicted by NUG starts by targeting the triangular gum areas nestled between the teeth. This region becomes ulcerated and covered in a whitish-greyish layer, indicating dead tissue.

Without treatment, the infection can persistently erode the tissue, causing significant gum destruction. Furthermore, it can extend its reach to affect the supporting bone, posing a risk of tooth loss.

Treating Necrotizing Ulcerative Gingivitis


When it comes to tackling necrotizing ulcerative gingivitis, prompt treatment is essential to reverse the damage before it's too late to recover lost gum tissue.

  • Prioritize Oral Hygiene: The foundation of treatment is maintaining meticulous oral hygiene. Given the sensitivity and discomfort, start gently. Begin with mouthwashes and an extra soft toothbrush.

  • Professional Cleaning: A crucial step involves visiting the dentist for professional cleaning, or scaling. This process, accompanied by the use of local antiseptics, clears away debris and bacterial buildup, creating an environment conducive to healing.

  • Antibiotics if Needed: In more severe and advanced cases, antibiotics might be necessary to help combat the infection.

  • Lifestyle Changes: If you suspect vulnerability to necrotizing ulcerative gingivitis or any form of gum disease, making positive lifestyle changes is key. This entails quitting smoking, managing stress, improving your diet, and considering supplements if necessary.

When Should a Gum Ulcer Raise Concern?

In most cases, an ulcer on your gums or anywhere else in your mouth should not be a cause for concern. Usually, it's a harmless occurrence that tends to resolve on its own.

However, even if your oral health is in top shape, there are certain signs you should pay attention to. These indicate something more serious than a simple canker sore or minor injury. We're talking about the possibility of malignancy or oral cancer.

So, let's address the big question: Can a mouth ulcer be a sign of cancer? The short answer is yes, but it's exceptionally rare. And when it comes to gums, it's even rarer as the tongue and lips are the primary sites affected.

When mouth ulcers turn out to be malignant, they often come with the following indicators:

  • You're a heavy smoker and drinker.
  • The ulcer doesn't show signs of healing after 2 weeks.
  • The ulcer feels firm and hard to the touch.
  • The edges of the ulcer are irregular and prominent.
  • The ulcer tends to bleed easily, even with the slightest touch.
  • The affected area extends beyond the ulcer itself.
  • Your lymph nodes in the neck are swollen.

If you see a few of these signs along with your mouth ulcer, it's really important to get a professional evaluation. This might involve more tests to reveal the nature of the issue.

Do's When Having a Mouth Ulcer

  1. Maintain Good Oral Hygiene: Keep your mouth clean by gently brushing your teeth and using a soft toothbrush. This helps prevent further irritation.

  2. Rinse with Salt Water: Gargle with a warm saltwater solution to soothe the area and promote healing.

  3. Choose Soft Foods: Opt for a soft diet to avoid aggravating the ulcer. Foods like yogurt, mashed potatoes, and oatmeal are gentle on the mouth.

  4. Use Over-the-Counter Relief: If needed, consider using numbing agents, antiseptic mouthwashes, or over-the-counter gels designed for mouth ulcers.

  5. Stay Hydrated: Keep yourself hydrated, as it can help maintain moisture in the mouth, aiding the healing process.

Don'ts When Having a Mouth Ulcer

  • Avoid Irritating Foods: Steer clear of spicy, acidic, and rough-textured foods that can worsen the pain.

  • Say No to Smoking: If you're a smoker, now is a great time to consider quitting or at least cutting back. Smoking can delay the healing process.

  • Skip Harsh Mouthwashes: Avoid using strong mouthwashes that can cause further irritation. Opt for milder, alcohol-free options.

  • Refrain from Touching: Don't poke or touch the ulcer with your fingers or tongue. This can lead to infection or further discomfort.

  • Don't Ignore Persistent Symptoms: If your ulcer doesn't improve or worsens after a couple of weeks, don't ignore it. Seek professional evaluation to rule out any serious concerns.
