Healthy roof of mouth

First and foremost, before knowing about what is happening with your mouth, take a look at your whole strong roof of the mouth.

The mouth seems to be the connection between the digestive tract and respiratory system. Covering the mouth is a mucous membrane or oral mucosa in medical term. You can see inside your mouth with a reddish pink color in normal condition. Gingivae or the gums appear with paler pink and embrace fully around the teeth.

Palate or mouth roof is separated into two parts: the front and the back parts. The former is hard; thereby physicians call it hard palate; the later is quite smooth and opposite to hard palate, it is also soft and called soft palate. They are covering by the mucous moisturizing membrane. This membrane also structures to the pink portion of lips.

Even, saliva has moistened the lips as well. If you have a healthy mouth and drink enough water, you can see your lips smooth, moisturizing. You can see more deeply inside your mouth with a uvula next to soft palate in the
back. It can be more explicit if you say “ahh” which looks like your doctors examine you.

Your uvula is healthy if it is pink, no blister, no black sore in the mouth. A very important structure of your mouth is your tongue which decides the taste of anything you put in your mouth. If your tongue is healthy, it appears with regular pink in your whole tongue, and it is covered by moisturizing mucosa membrane.

The surface of the tongue also has a rough texture created by many tiny bumps or papillae. The papillae are dispersed regularly as well.

What is a blood blister and what does blister look like?

This is a sort of blister forming because of the damage of both subdermal tissues and blood vessels while retaining the skin. Under the skin, we can see a pool of blood, node, lymph, pimple inside mouth or another word, tiny blood blister, black spot, bubble… Once, it is punctured, a dark fluid is released. Some blisters are painful; some are painless depending on the structure and the causes of the bump.

The location of blood blister inside mouth is various. You can see blood blister on lip, water blister on the rim, blister inside lip, blood blister on gums, blister under tongue, blood blisters inside cheek or black spot inside lip, skin tag inside the mouth, or more general speaking, just black sore in the mouth.

Regarding a medical term of blood blisters, physicians call a blister as a cyst.

When its diameter is more than 5 mm, they call it a bulla.

Causes of blood blister in the mouth

There are a variety of reasons causing pimple inside your mouth.

1. Ulcers in your mouth

When you take medication to treat for some illness, some side effects of the drugs can cause ulcers inside your mouth. There are two types of mouth ulcers:

  • Canker sores and cold cores. Two most common reasons cause ulcers in your mouth are local trauma and recurrent ulceration inside your lips. When it comes to local trauma, it might cause by mechanical trauma, chemical injury and thermal injury.
  • Mechanical trauma arises because of some aspects such as dentures, sharp/damaged teeth or even braces. Moreover, it can happen due to cheek biting, eating rough foods, scratching with sharp objects such as fingernails, metal. After ten days removing the cause from the ulcers, it can be healed entirely as a natural healing process. If it lasts longer, you can get some troubles with it, and further investigation needs to be taken.

The chemical injury comes from contacting between aspirin and oral mucosa as an example. Chemical burns also follow by taking bisphosphonates if these drugs are dissolved in your mouth. More significantly, in this situation, you will feel more painful.

Regarding thermal injury, it happens when mucosal mouth contacts with hot liquid or hot food. The most common injury is the palate. Moreover, it also occurs on the tongue or lips.

Recurrent ulceration inside your lips, or in other words “canker sores,” might be resulted from dentures, sharp/damaged teeth, or even braces. The feature of this ulceration is shallow round, obviously defined, and very painful, not related to systemic disease.

Canker sores can start at the youngster and get worse in the elder ages. It also has relationships with some conditions such as under a lot of pressure, trauma in the local site, allergy with food, changes of hormones, smoking cessation. This type of canker sores will disappear within 10-14 days and it will remove without a scar.

2. A rare disorder: Angina Bullosa Haemorrhagica (ABH)

This disease gains its popularity in elderly people. We can see a single blister in medium side inside the cheek or under the tongue and filled with blood. Luckily, they usually break quickly and become opened wounds but they can
recovery spontaneously without treatment. The patients suffer from some disorders like diabetes mellitus, overuse steroid or mouth trauma can have a high risk of this disease.

3. Allergies on food

Whenever you eat some typical foods, and you get a zit inside mouth from several hours to some days later, the most common reason for this condition might cause by your body can’t stand with this food, or in medical term, it’s food allergy.

4. Platelet decrease

In term of medical terminology, this condition is called idiopathic thrombocytopenic purpura.

5. Nutritional issues

Although our bodies need a little of vitamin and mineral, they play a crucial role in building healthy structure of the mouth. It maintains the stability of the cell, especially the epidermal cells and the connective tissues to keep hearty mucosal membrane in the mouth. One of the most important vitamins were responsible for this is vitamin C (acid ascorbic) and vitamin B12 (cobalamin).

Vitamin C is a water-soluble vitamin which is essential for the collagen biogenesis. You have already once heard about the function of collagen? It is a crucial component to build connective tissue and in turn is necessary for wound healing.

As a strong antioxidant, acid ascorbic is considered to lessen oxidative stress to the cells of the body and thereby, it helps lower the risk of cancer. Blood blister that causes by some virus such as HPV has high risk of cancer, you should remember that.

You can supply enough your vitamin C need every day by food intake. Some fruits and vegetables contain lots of acid ascorbic such as papayas, berries, broccoli, oranges, tomatoes, kiwifruit, green peas. Try to eat more fruits and fresh vegetable routinely.

Vitamin B12 or cobalamin is also a water-soluble and one of the 8 complex B vitamins. It plays an important role in the metabolism of cells, especially in the process of DNA replication, fatty acid and some amino acid converting in the metabolism cycle of our bodies.

The quicker metabolic rapid is in our bodies, the better wound healing process occurs. The sources of vitamin B12 is available and rich in some animal products such as eggs and milk, liver, meat of fish, fowl…

All in all, those is the reason why If your diet lacks some vitamins such as vitamin C or/and vitamin B12, it may trigger zit in your mouth. Find your smart choice in daily meal to get a healthy mouth.

6. Medication

All drugs are chemical substances as well. When it contact with your mouth, obviously, it can generate some reactions with your mouth cells. Those reactions apart from treatment effect and harm to our health, we call this is adverse effect or side effect.

Side effects of some drugs may cause blood blister in your mouth because it damages the normal cells and structure of your mouth, thereby, be careful to use the medicine in right way.

If some allergic reaction happens, please stop taking those pills and ask your doctors. Moreover, some condition, the adverse effects of the drugs did not reveal in the mouth.
