15 Possible Reasons For Bump On The Roof Of The Mouth

Your mouth is made up of sensitive tissues and is affected due to the slightest change that happens in the body. The bump on the roof of your mouth is something to be worried about if it does not go away in a short span. It is caused due to a wide variety of reasons, from something as simple as tissue trauma to more grave ones like oral cancer.

Gladly, most of the root causes are treatable. The roof of the mouth is divided into two parts, hard and soft palate. The severity depends on placement and growth of bumps on the mouth roof. Let’s discuss each with their treatment plan as well.

1.Canker Sores

Canker sores are round lesions that appear on the roof of the mouth. They are commonly found in the cheeks and gums and grow in other unusual places too. Canker sores are flat and have delicate surfaces. They appear as a sore bump on the mouth roof and may be painful.
Canker sore bumps are usually not found on the mouth roof. Instead, it is more prevalent in the cheek and lip. The reason why they appear can be irritation due to braces, illness, stress, etc.


Canker sores presence is an unpleasant and painful sight, and there are many ways to get rid of it. Mostly, ample resting is important. Do not touch the affected area; go gentle and take care while brushing and flossing.
Next, diet modification is a must. Steer clear of crunchy, acidic edibles that would irritate the already painful bump on the roof of your mouth. Moreover, avoid food or beverages that are extremely hot. Instead, use ice packs to lessen the redness and pain.
With a soft diet and careful brushing, warm salt water rinse works wonders to decrease irritation and inflammation.


Hasty eating habits can often lead to a small bump on the roof of the mouth. Consuming food and beverages high in temperatures like coffee or tea can burn the inside of your oral cavity. The most affected areas are tongue and roof of the mouth having soft tissues which may develop a sore bump on it.
This protrusion might seem little and not troublesome but will cause immense pain every time you eat until it heals up. However, the good news is that our body has a great healing mechanism; the damaged tissues forming the bump on the mouth roof slough off within a few days to weeks.


Burn in the oral cavity requires time to heal. It is best not to eat or drink anything hot that might irritate the insides. Try consuming soft mashed foods; it would be a plus if cold, like a smoothie bowl or mashed bananas.

Cold Sores

Cold sores are also known as fever blisters caused due to the presence of a certain type of herpes virus. Usually, this virus forms a bump on the lips and mouth cavity as well as the roof, which is not painless. Other signs and symptoms of a cold sore are:

  • Tingling feeling before the palate bump arrives
  • Blisters that appear in the form of patches
  • Open blisters
  • Premature bursting and crusting of the bump

Cold sores are extremely contagious. Just like their appearance, they go away easily too, within 2 weeks approximately. However, avoid close contact with the affected individual to stop the spread.


If the small bump on the roof of your mouth comes and goes time and again, it is better to use prescription medicines for their treatment. The best time to put on topical medicine is when the sores start developing.


The oral cavity is filled with salivary glands and ducts throughout the mouth. Sometimes, when you see a smooth, painless bump on the roof of the mouth, it may be due to blockage in one of the ducts.


There is no specific treatment for mucoceles; they pop on their own. However, a large bump on the mouth palate may require medical intervention. If the roof of your mouth develops a hard bump, like a salivary stone, your dentist will schedule an appointment for its removal.

Epstein Pearls

The dentists often call this a gingival cyst. It is a condition that affects newborns only. Mostly tiny white bumps appear on the gums behind the area where their upper teeth would come or the roof of the mouth.
It is a tiny protrusion of size 1 to 3 cm, and may look bigger in your baby’s mouth. These lumps are benign and go away on their own.


It is only found in newborns and heals with time, and doesn’t require medical attention.


Accidental falls, sports activities, or automobile incidents are the main reasons facial injuries happen. But, when it comes to injuries on the palate, something as simple as loss of brush control or spoon hitting the roof of the mouth can lead to a bump on it.


Normally, all you need is to give it time to heal itself. Just make sure not to eat anything that might irritate the bump on your palate.

Torus Palatinus

A solid hard bump on the roof of your mouth may be “palatal tor.” These are tiny bony lumps that spread from the midline to the high line of your palate. Usually, they are painless, but their location causes irritation during talking, eating, or drinking. Tori may grow larger each year.


The only treatment option available is surgical removal.

Oral Cancer

This is something no one wants to suffer from. It is one of those grave diseases that appear without any obvious symptoms. Therefore, it is best to rush to your doctor when nodules or bumps appear in your oral cavity, which do not disappear within a week or two.


Your oncologist should set a routine screening and treatment plan after getting done with the biopsy.

Yeast Infection

Thrush is an oral yeast infection that affects the mouth. It is when the fungus candidiasis albicans overgrowth. Mostly this condition affects infants, immune-compromised individuals, and older people. You are most likely to have thrush with bumps on the roof of your mouth if you have dentures that are kept on throughout the night.


If you have dentures, then start with cleaning and make sure to remove them at night. Ensure cleaning of your mouth daily with soft fabric and warm water. Use anti-fungal medicine to clear out fungal load in the mouth. Having a good oral hygiene regime is essential to prevent the buildup again.

Hand Foot and Mouth Disease

People of all ages can get hand, foot, and mouth disease. However, it is prevalent amongst infants and young children. Symptoms include rashes in the palms, soles of the feet, and all over the mouth. The bump or lesion due to this reason is flat and red.


Usually, the virus which causes this issue is left to complete its course. But, your dentist can provide you with a mouth rinse that would numb the area so that you eat easily.

Squamous Papilloma

Mostly, it is found beneath the tongue but the bump may grow on other areas like the roof of your mouth too. They appear as tiny finger-like projections resembling cauliflower shapes. Squamous papilloma is non-cancerous, so do not get worked up about its presence.


Papillomas may interfere with your appearance or can make eating difficult. In such cases, it is best to get it surgically removed. Fortunately, they never recur if properly cut from their base.


In this case the individual has extra teeth in the set, 33 instead of regular 32. Mostly, the extra is found near wisdom teeth or between the two front teeth. It is suggested that the main cause of their growth is gene-related.


Usually, people leave it as it is unless they are disrupting eating or drinking or putting unnecessary pressure around others. Extraction becomes necessary if the extra ones are found near wisdom teeth.

Nasopalatine Duct Cyst

When cysts appear between your nasal sinuses and roof or palate of the mouth, it is a condition named a nasopalatine duct cyst. It appears as bumps in the middle of the roof of the mouth. Usually, there are no other symptoms involved.


Complete removal of the cyst is considered the most appropriate treatment method. Sometimes, the dental surgeon may go for bone graft to fill the void due to large cysts.

Benign Tumors

Benign tumors are non-cancerous growths that can manifest the mouth just like any other body part. They do not spread.


Surgical removal is the treatment option for these benign growths.


Electrolyte imbalance in the body due to dehydration is one of the reasons why a dry bump may appear on the roof of your mouth.


Consume 8 glasses of water daily for adequate hydration.
