Red spots on the palate? Learn about the types and care

Cold sores (fever blisters) appear on the outside of your mouth, often on your lips. A virus causes them, and they’re very contagious. If you have a fever blister, you should avoid sharing personal items with other people to reduce the spreading of the virus.

Mouth Ulcer

Mouth ulcers are small sores that form on your gums, lips, tongue, inner cheeks or roof of your mouth. Lots of different things can cause them, including minor injuries, hormonal changes and emotional stress. Many mouth ulcers go away on their own. Others may require treatment.

Overview

Mouth ulcers are often white or yellow in the middle with red around the edges.

What is a mouth ulcer?

A mouth ulcer is a sore that appears anywhere inside your mouth. These sores are usually red, yellow or white, and you might have one or several.

You can get mouth ulcers on your:

• Gums.
• Tongue.
• Roof of mouth (palate).
• Inner cheeks.
• Inner lips.

These sores are often painful and can make eating, drinking and speaking uncomfortable.

Mouth ulcers can be alarming. However, they’re not a sexually transmitted infection (STI) and you can’t get or spread them from kissing or sharing food and drinks. Aside from any pain and discomfort, mouth ulcers are usually harmless and go away on their own in a week or two. But some types of mouth sores could point to underlying health conditions like viruses, autoimmune diseases or gastrointestinal issues.

Types of mouth ulcers

There are many different types of mouth sores and lesions, including:

• Canker sores (aphthous ulcers). These are the most common type of mouth ulcers. Healthcare providers aren’t exactly sure what causes them or why some people get them more than others do. Causes include minor trauma (like biting your cheek), acidic foods and even stress. Canker sores are usually white or yellow with red around the edges.
• Oral lichen planus. This condition can cause itchy rashes and lacelike, white sores inside your mouth. Oral lichen planus is an immune system response and most commonly affects women and people assigned female at birth (AFAB) age 50 or older.
• Leukoplakia. This condition causes white or gray patches inside your mouth. It develops because of excess cell growth. Chronic irritation from things like smoking or chewing tobacco can cause it. But sometimes it happens for no apparent reason. Leukoplakia lesions usually aren’t cancerous.
• Erythroplakia. Erythroplakia is another symptom of smoking or chewing tobacco. People with erythroplakia have red patches that commonly appear behind their lower front teeth or under their tongue. Unlike leukoplakia lesions, erythroplakia patches are usually precancerous or cancerous.
• Oral thrush. An overgrowth of yeast called Candida albicans causes this fungal infection inside your mouth. It commonly happens after antibiotic treatment or when your immune system isn’t as strong as it usually is. Oral thrush causes red and creamy white mouth sores and patches.
• Mouth cancer. Oral cancer lesions can show up as red or white mouth sores or ulcers. These sores won’t heal on their own. If you have a mouth ulcer that hasn’t gone away after three weeks, tell your healthcare provider.

Symptoms and Causes

What are the symptoms of a mouth ulcer?

Mouth ulcers are usually easy to spot. They appear as sores on your gums, tongue, inner cheeks, inner lips or roof of your mouth.

Mouth sores are typically:

• Red around the edges.
• White, yellow or gray in the center.

You may only develop one ulcer, or there might be more. Other symptoms could include:

• Swelling around the ulcers.
• Increased soreness when brushing your teeth.
• Pain that worsens when eating spicy, salty or sour foods.

What causes mouth ulcers?

Mouth ulcers may occur for a number of reasons, including:

• Minor tissue injury from dental work, such as having a cavity filled.
• Accidentally biting your cheek or tongue.
• An allergic reaction to certain bacteria.
• Wearing braces or retainers.
• Using harsh or abrasive toothpaste.
• Eating lots of acidic foods, such as oranges, pineapples and strawberries.
• Hormonal changes during your period.
• Stress.
• Lack of sleep.

Health conditions associated with mouth ulcers

Certain health conditions, including many autoimmune diseases, can also cause mouth ulcers. These conditions may include:

• Vitamin deficiencies.
• Viral, bacterial or fungal infections.
• Crohn’s disease.
• Celiac disease.
• Reactive arthritis.
• Lupus.
• Behçet’s disease.

Are mouth ulcers contagious?

No. Unlike cold sores, mouth ulcers aren’t contagious, and they can’t spread through kissing or sharing food.

Cold sores (fever blisters) appear on the outside of your mouth, often on your lips. A virus causes them, and they’re very contagious. If you have a fever blister, you should avoid sharing personal items with other people to reduce the spreading of the virus.

Diagnosis and Tests

How do health providers diagnose mouth ulcers?

A healthcare provider can diagnose a mouth ulcer with a visual examination. If you have a severe breakout, or if they suspect a specific health condition, they may order blood tests.

Management and Treatment

How do you treat a mouth ulcer?

While most mouth sores heal on their own, your provider may prescribe medications to help ease discomfort. Common mouth ulcer treatments include:

• Antiseptic gels or mouth rinses like Orajel™ or Anbesol®.
• Steroid ointments like triamcinolone.
• Immunosuppressants (in severe cases).

How to cure mouth ulcers fast naturally

There are also things you can do at home to relieve mouth sore symptoms:

• Drink plenty of water.
• Practice good oral hygiene to keep your mouth as clean as possible.
• Rinse your mouth with warm saltwater a few times each day.
• Make a mixture of equal parts hydrogen peroxide and water and rinse your mouth twice a day.
• Avoid hot and spicy foods until the ulcer heals.
• Use an over-the-counter (OTC) topical anesthetic like Orajel™ or Anbesol®.

Prevention

Can I prevent mouth ulcers?

While you can’t prevent mouth ulcers altogether, there are things you can do to reduce your risk:

• Brush your teeth twice daily and floss once daily for optimal oral health.
• Use a soft-bristled toothbrush to avoid tissue irritation.
• Eat a healthy diet rich in fresh fruits and vegetables.
• Visit your dentist regularly for checkups and cleanings.

If your provider thinks you have an underlying condition that causes sores, treating your condition can reduce the risk of ulcers returning. Talk to your provider about ways to manage your health.

Outlook / Prognosis

How long do mouth ulcers last?

In most cases, mouth ulcers go away on their own in about 10 to 14 days. If you have a mouth sore that lasts longer than three weeks, schedule an appointment with your healthcare provider. They can recommend treatment and tell you how to get rid of your mouth ulcer.

Additional Common Questions

Mouth ulcer vs. canker sore: What’s the difference?

“Mouth ulcer” is a broad term that describes any sore or ulceration inside your mouth. As we mentioned earlier, canker sores are the most common type of mouth ulcer. They affect about 20% of the general population. Many people use the terms “mouth ulcer” and “canker sore” interchangeably.

You might get a canker sore if you have a folate, vitamin B or iron deficiency. But in most cases, canker sores appear without a known cause and for no apparent reason. They can also recur (return), meaning they come and go over the course of your lifetime.

Some people confuse canker sores with cold sores (fever blisters), but they’re very different. A canker sore appears inside your mouth. A cold sore forms outside your mouth, usually on your lips. Canker sores aren’t contagious, but cold sores are.

How do you know if your mouth ulcer is bad?

Anytime you have a mouth sore that lasts longer than three weeks, schedule a visit with your provider. Mouth ulcers that don’t go away could point to other underlying health conditions.

Are mouth ulcers a sign of cancer?

Usually not, but it’s possible. A mouth ulcer that doesn’t go away could be a sign of oral cancer. In most cases of mouth cancer, mouth ulcers appear on or under the tongue.

Most mouth ulcers are harmless. But if you have a mouth sore that won’t heal, you should talk to a healthcare provider.

A note from Cleveland Clinic

Most mouth ulcers aren’t dangerous. But they can be a huge inconvenience. Mouth sores cause pain that can keep you from enjoying the things you love, like eating certain foods, drinking comfortably, playing an instrument or kissing your partner. Your mouth ulcer will probably go away within two weeks. In the meantime, you can try over-the-counter medications and home remedies to reduce pain until the sore heals. If you have a mouth ulcer that doesn’t heal after three weeks, schedule a visit with a healthcare provider. You might have an underlying condition that needs treatment.

Red spots on the palate? Learn about the types and care

Have you developed red dots or spots on the palate? There are many types, and depending on the type of pathology, the symptoms will be different. Some patients have red spots on the roof of their mouth that are quite painful, while others don’t even notice them, and there are also people with palate spots who have minor discomfort but can go on with their normal life.

If you think you have these red spots, you should visit our dental clinic in Malaga so that a specialized dentist can see you and tell you what treatment you should follow to eliminate these small and annoying spots.

Types of red spots or stains that appear on the palate

Burns: having eaten something very hot, it is possible that red spots may appear on the roof of your mouth. In fact, the patients we receive with burns not only have these red spots, but also injured tissue.

Reaction to medication: some people may have reactions to medication that cause red spots on the palate, while they may also develop when the medication is allowed to dissolve in the mouth.

Canker sores: Canker sores are sores that can vary in size and are manifested by a spot that has a white centre and the rest is red. They can appear in the mouth, tongue, cheeks, lips, gums, throat or palate. They are not contagious and usually last about 2 weeks, and appear when the body’s defences are lowered or due to trauma. Our dentists at Gross Dentistas will make sure that it heals properly and that it does not bother you too much.

Herpes: this virus, once the patient has been infected, does not disappear from the body. That is why people who suffer from it usually suffer from it several times a year. When it appears in the form of red spots on the palate, it does not usually hurt, but it must be treated with medication so that it does not increase in size and can spread.

Candida: this is a fungus that produces red or white spots in the mouth. It is usually found in people with diabetes and also in young children. It must be treated with antifungal medication prescribed by the dentist.

Coxsackie virus: this especially affects children under 5 years of age and causes red spots on the roof of the mouth, which are usually painful.

Malignant lesions: when you have red spots on the palate, it is very important to make regular appointments with your dentist to detect the source, as well as to rule out worse diseases. The professional will be able to analyse if something is not working properly in our organism.

Red spots on the palate of a child: how to fix them

As you have read, some of the types of red spots on the palate particularly affect children. This is something that worries many parents, and rightly so.

That is why we have a doctor who specialises in pediatric dentistry, which is the branch of dentistry that treats children. Thanks to her work we will be able to detect the type of red spot in time, and what treatment is the most appropriate to eliminate it as soon as possible and avoid any kind of pain or discomfort for the child.

It is important that you bring your children to the dentist when they are young for check-ups to detect these red spots on the roof of the mouth. They will also get used to it, and avoid that popular “fear of going to the dentist” that many teenagers and even adults suffer from.
