Meaning
This refers to an inflammation, swelling or a growth that sometimes increases in size. The inflammation may be hard, painful, and small or appear colored. The bump may develop on either the soft or the hard palate. However, they also occur on the lips or the cheeks.
Causes
There are various reasons you may get bumps on the palate. These are described below;
Canker sores
These are small, non-contagious ulcers, mostly red or white in color. These sores cause discomfort while you are eating or even talking. They are of two types; the simple canker sores which appear at about four times per year and the complex canker sores.
According to the American Academy of Otolaryngology, the lumps develop on your mouth, tongue, lips or cheeks and they can only appear on the soft palate not the hard palate.
They can last for 5 to 10 days but if they persist, you should seek medical advice from an expert. It is also advisable that you use benzocaine.
Cold sores
These are blisters filled with fluid on the lips and sometimes on the mouth’s palate caused by herpes simplex virus. It is characterized by itching of the lips surface before blister formation, and painful blisters filled with watery liquid which eventually appear as an open sore.
Unlike canker sores, cold sores are highly contagious especially during the healing process which takes a few weeks. It is recommended that you use Valtrex to speed up the healing process.
Injuries
Injuries such as burns from hot liquids and cuts may also cause lumps on the palate. During the healing process of a burn, you can develop a blister that contains fluid. Moreover, cuts can swell bringing about the feeling of a lump.
Often, the injuries of the mouth are accompanied by pain, bleeding of the cut tissue or a burning sensation. The wounds heal fast on their own though you can use salt, water or sodium peroxide for faster healing.
Smoking
This is one of the most common causes of bumps on the palate. You will notice a group of small white bumps with red sinkhole in the middle on the surface of the hard palate. This state is known as nicotine stomatitis and lasts for 1 to 2 weeks.
Lumps caused by smoking may appear reddish at the center. The only way to manage bumps in the mouth caused by smoking is to stop the act.
Torus Palatinus
This refers to the projection of a bone that appears on the palate of the mouth. In most cases, the condition results when you grind your teeth.
Unlike other causes of bumps, this requires no treatment but if the condition worsens then you can see a doctor for medication which in most cases is removal of the protruding bone.
Mucoceles
This is a harmless cyst like bulge that occurs due to blockage of the salivary glands in the mouth. Mostly, this occurs when there is an obstruction on the mouth’s palate which traps saliva forming a tiny pinkish bump.
The cyst causes no harm or pain but when they grow bigger, they may cause a lot of discomfort. The mucous cysts heal themselves though if the condition persists you should see a dentist or a specialist for checkup and necessary treatment.
Tooth abscess.
This refers to a condition whereby a painful infection occurs at the root of your tooth or in other cases between the gum and the tooth. This infection is caused by bacteria in the nerve of the tooth.[1] As a result of this, the bumps develop on the slanting edge of the palate.
In most cases, the infection is manifested by a foul odor, bitter taste in the mouth and sometimes accompanied by fever. For this, the health specialist may decide to get off the abscission from your mouth and under severe conditions a surgery might be carried out to eliminate the infected tissue.
Hyperdontia
Another cause of lumps on the roof of your mouth is hyperdontia. This is a condition that is caused by development of too many teeth. Often, this occurs when you fail to get rid of your milk teeth causing extra teeth to develop on the roof of the mouth.
This leads to facial pain, headache and jaw pain. This can be treated if diagnosed (mostly through x-rays). The dentist can remove the extra teeth without causing any harm to the rest of your teeth.
