Common Causes of Red Spots on the Roof of the Mouth
Some typical reasons you may develop red spots on the palate include:
Canker Sores
Canker sores are small ulcers that can form on the soft tissues in your mouth. They usually appear as round, white spots with a red border. Canker sores are commonly triggered by:
- Injury from rough foods like chips or sharp toothbrush bristles
- Stress
- Hormonal changes
- Food allergies
- Vitamin deficiencies
- Weakened immune system
Cold Sores
Oral herpes is a viral infection that causes fluid-filled blisters known as cold sores. Cold sores often start as red spots on the roof of the mouth before blistering. They are highly contagious and usually caused by the herpes simplex virus type 1 (HSV-1).
Oral Thrush
An overgrowth of a yeast called Candida in the mouth leads to the development of white, red or pink patches on the palate and tongue. Oral thrush is common in babies and adults with weakened immune systems. The use of antibiotics, dentures, inhaled corticosteroids, and smoking can increase thrush risk.
Scarlet Fever
Scarlet fever is caused by a bacterial infection that results in a bright red, bumpy rash on the body. Red spots may also develop on the roof of the mouth. Scarlet fever often begins with a sore throat and high fever.
Strep Throat
Strep throat is an infection caused by Streptococcus pyogenes bacteria. In addition to throat pain and fever, red spots may appear on the palate. Strep throat can occur at any age but is most common in children 5-15 years old.
Hand, Foot and Mouth Disease
Coxsackievirus infection leads to hand, foot and mouth disease (HFMD). Red spots and ulcers can develop on the roof of the mouth, gums, tongue, palms of the hands, and soles of the feet. HFMD is highly contagious and mainly affects children under 10.
Oral Lichen Planus
Oral lichen planus is an inflammatory condition that can cause lace-like white patterns or red patches on the inner cheeks, gums, tongue, lips or roof of the mouth. The rash may range from mild to painful.
Oral Cancer
In rare cases, red spots on the roof of the mouth may be a sign of oral cancer, especially if they do not heal. Other oral cancer symptoms can include difficulty swallowing, hoarseness, and white or red patches on the gums, tongue or tonsils.
When to See a Doctor
Schedule an appointment with your doctor or dentist if you have red spots on the roof of your mouth combined with:
- Severe pain
- Bleeding from the spots
- Difficulty eating, drinking or swallowing
- Fever over 101°F (38°C)
- Fatigue, weakness or dehydration
- Persistent bad breath
- Unexplained weight loss
- Spots lasting longer than 2 weeks
Seeking timely medical care can allow for proper diagnosis and treatment of the underlying cause.
Diagnosing Red Spots on the Roof of the Mouth
To diagnose the reason for red spots on your palate, your doctor or dentist may:
Ask About Your Symptoms
They will inquire about your medical history and when you first noticed the spots. Be prepared to describe any accompanying symptoms like fever, sore throat or mouth pain.
Examine Your Mouth
The doctor will use a tongue depressor to visually inspect the spots, their appearance, size, location and if they can be wiped off.
Swab the Spots
A culture of the sore may be taken with a cotton swab and sent for laboratory testing. This can identify certain bacteria, viruses, fungi or yeasts.
Order Blood Tests
A blood sample may be drawn to check for elevated white blood cell count indicating infection or antibodies fighting oral pathogens.
Perform a Biopsy
If cancer is a concern, the doctor may surgically remove all or part of the spots to be examined under a microscope. This can rule out or confirm oral cancer.
Medical Treatment for Red Spots on the Roof of the Mouth
Treatment will depend on the underlying cause. Your doctor may prescribe:
Antibiotics for Bacterial Infections
Oral antibiotics like penicillin or amoxicillin fight off bacterial causes like scarlet fever or strep throat. Take the full course as directed.
Antiviral Medication for Viral Infections
Oral antiviral drugs like acyclovir and famciclovir help control viral causes like oral herpes or HFMD.
Antifungal Medication for Oral Thrush
Antifungal drugs like fluconazole or nystatin are used to treat candida fungal infections causing thrush.
Corticosteroid Cream or Mouthwash
For red spots due to inflammatory conditions like oral lichen planus, topical corticosteroids help reduce discomfort and swelling.
Surgery to Remove Cancerous Tissue
If cancerous, sections of the affected mouth tissue may be surgically excised. Radiation or chemotherapy may also be warranted.
Home Remedies for Mouth Roof Red Spots
Some natural remedies can also help soothe red spots on the palate:
Saltwater Rinses
Gargling with warm saltwater helps cleanse the area and alleviate pain.
Aloe Vera Gel
Pure aloe vera gel has anti-inflammatory and healing properties that can be soothing on roof of mouth spots.
Canker Sore Medications
Oral numbing gels containing benzocaine or OTC medications like Zilactin can reduce canker sore discomfort.
Cold Compress
Gently holding an ice cube against the spots helps relieve pain and inflammation.
Proper Oral Hygiene
Brushing and flossing daily keeps bacteria in check and promotes healing.
Preventing Red Spots on the Roof of the Mouth
You can lower your risk of developing red spots on your palate by:
- Avoiding injury to the mouth from rough foods, teeth, or oral devices
- Managing stress levels
- Eating a balanced, nutrient-rich diet
- Quitting smoking and restricting alcohol intake
- Practicing good oral hygiene habits
- Not sharing drinks or utensils with those who are sick
