8 Causes Behind Bump on the Roof of Your Mouth

Have you ever found an uncomfortable bump on the roof of your mouth and wondered what caused it? Such an occurrence can be concerning. If they persist for long, an oral biopsy can rule out whether they are serious. So, let’s discuss what might have caused this inconvenient guest to appear inside your mouth:

  1. Torus Palatinus
    It is a bony growth on the roof of the mouth. Some people are born with it, while others develop it later in life. It is usually painless. However, large growths can cause discomfort and make eating, swallowing, or chewing difficult.
  2. Canker Sore
    Canker sores are small sores that appear inside the mouth, including on the roof. They look round and are whitish or yellowish with a red ring around them. They can appear alone or in small groups. Canker sores are painful, especially during the first three to four days. They usually heal on their own.
  3. Cold Sore
    Cold sores often appear on the lips but can also show up on the roof of the mouth. They happen because of oral herpes, specifically the herpes simplex virus type 1 (HSV-1). Cold sores are contagious and start with a tingling, burning, or tender feeling before turning into a blister. This might crust over before healing.
  4. Injury
    Injuries to the roof of the mouth can cause swelling or a blister that feels like a bump. These injuries might also involve bleeding or pain and usually heal on their own.
  5. Epstein Pearls
    Epstein pearls are whitish-yellow cysts on the gums or roof of the mouth, common in newborn babies. They look like teeth coming in and typically disappear within a few weeks after birth.
  6. Squamous Papilloma
    Squamous papillomas are harmless. Painless growths occur due to the human papillomavirus (HPV). They often appear on the tongue or roof of the mouth. Squamous papillomas are noncancerous and don’t need treatment. However, oral surgeons can remove them if desired.
  7. Infection
    Certain infections can cause bumps on the roof of the mouth. These include candidiasis and hand, foot, and mouth disease. Candida yeast is the culprit behind this fungal infection. It appears as white patches on the roof of the mouth, inner cheeks, tongue, and throat. They can be sore and painful, especially when eating or swallowing.
  8. Oral Cancer
    Cancer on the roof of the mouth, known as hard palate cancer. It is rare and includes squamous cell carcinoma and salivary gland cancer. The risk factors are smoking or alcohol consumption.

Professional Diagnosis

To determine the cause of the bump on the roof of your mouth, a doctor will examine it.  They will also check your medical history and any food allergies (if any). Your dentist or oral surgeon might recommend a biopsy or surgical removal of the bump. 

Wrapping Up

The appearance of lumps and bumps inside your mouth is usually harmless. You just need to wait it out, and they disappear. However, if a bump on the roof of your mouth doesn’t go away after a week, there could be a serious underlying cause.
