Not to be confused with Granuloma
Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process.[1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps. Its histological appearance is characterized by proliferation of fibroblasts and thin-walled, delicate capillaries (angiogenesis), and infiltrated inflammatory cells in a loose extracellular matrix.

Granulation tissue is composed of tissue matrix supporting a variety of cell types, most of which can be associated with one of the following functions:[citation needed]
An excess of granulation tissue (caro luxurians) is informally referred to as "proud flesh".[3]

Initially, it consists of a network of type-III collagen, a weaker form of the structural protein that can be produced rapidly. This is later replaced by the stronger, long-stranded type-I collagen, as evidenced in scar tissue.

The main immune cells active in the tissue are macrophages and neutrophils, although other leukocytes are also present. These work to phagocytize old or damaged tissue, and protect the healing tissue from pathogenic infection. This is necessary both to aid the healing process and to protect against invading pathogens, as the wound often does not have an effective skin barrier to act as a first line of defense.

It is necessary for a network of blood vessels to be established as soon as possible to provide the growing tissue with nutrients, to take away cellular wastes, and transport new leukocytes to the area. Fibroblasts, the main cells that deposit granulation tissue, depend on oxygen to proliferate and lay down the new extracellular matrix.
In vascularisation, also called angiogenesis, endothelial cells quickly grow into the tissue from older, intact blood vessels. These branch out in a systematic way, forming anastomoses with other vessels.

After getting a tooth removed, white tissue made of blood vessels, white blood cells, and collagen may form in the tooth socket as part of the healing process. But if you have symptoms of an infection, you may need medical care.
Tooth extraction is the most common oral surgery. Each year in the United States, more than 5 million people get their wisdom teeth extracted. Many other people get teeth pulled because of overcrowding, infections, or tooth decay.
If you&#;ve recently had a tooth pulled, you may notice something white form in your tooth socket. In most cases, this white material is granulation tissue, a fragile tissue made up of blood vessels, collagen, and white blood cells. Granulation tissue is part of your body&#;s natural healing process and isn&#;t a cause for concern.

If you&#;re also experiencing severe pain, the white material in your tooth may be a sign of a complication like an infection or dry socket. Keep reading to find out how you can tell the difference between your body&#;s natural healing process and other conditions.
If you aren&#;t experiencing severe pain 2 to 3 days after your tooth extraction, the white tissue you&#;re seeing likely isn&#;t a cause for concern. If you are experiencing pain, it may be a sign that you&#;ve developed an infection or dry socket.
After your tooth is extracted, your body will start its natural healing process. Your mouth heals in the same way as other parts of your body.
Within 24 hours of your tooth extraction, a blood clot will form in your socket to stop the bleeding. Once the clot forms, your body will start building granulation tissue to cover the wound. This tissue often appears a creamy white color and consists of collagen, white blood cells, and blood vessels.
The formation of granulation tissue is a sign that your socket is healing properly. It shouldn&#;t be a cause of concern if you aren&#;t experiencing any other symptoms.
After removing the tooth, your dental surgeon will put gauze over the extraction site to control bleeding. It&#;s possible that a piece of the gauze can get stuck and leave behind a small piece of cotton.
Unless the gauze is causing pain, you can leave it alone and eventually your body will take care of it.
Dry socket is the most common complication of getting a tooth extracted. About 1 to 5 percent of people who get a tooth pulled will develop dry socket. It occurs when the blood clot that forms over your tooth socket either fails to develop or falls off before your gum fully heals.
The development of dry socket can expose bone and nerves.
Symptoms of dry socket include:
If you think you may have dry socket, you should call your dentist or oral surgeon right away. The hallmark symptom of dry socket is severe pain several days after surgery.
White spots in your mouth may be pieces of food debris left behind after eating. These food particles aren&#;t dangerous by themselves, but they do have the potential to dislodge the blood clot while your socket is healing.
After at least 24 hours have passed from your surgery, you can rinse your mouth with a saltwater rinse to dislodge food particles. Try mixing half a teaspoon of salt with eight ounces of water.
In some cases, you may notice white or yellow pus after extraction. Pus is a sign of an infection. Other signs of an infection include:
If you think you may have an infection, you should see your dentist right away. Your dentist can confirm the presence of an infection and prescribe antibiotics.
If the white material you&#;re seeing accompanied with pain, you should contact your dentist right away if it falls out. This condition is called dry socket. It&#;s the most common complication of tooth extraction.
When this material falls out, your bone and nerves become exposed. Exposed nerves cause pain that can radiate from your socket to the side of your head. Exposed bone leaves you at risk of developing an infection.
A study looking at 2,214 people who had permanent teeth extracted found that 1.8 percent of people developed dry socket.
Any condition (smoking, creating a suction in your mouth, playing with the extraction area with your tongue) that results in premature removal of the blood clot formed in the socket of the tooth could lead to an increased likelihood of developing dry socket.
Plaque is a sticky film made up of bacteria. Normally, brushing your teeth and flossing breaks up this film. However, after several days of not being able to clean your tooth socket, you may notice white plaque forming around the wound. Once you&#;re able to clean around your extracted tooth normally, the plaque should go away.
You may also notice that your gums turn white around your wound. This is usually caused by the trauma of the surgery and should go away after a few days.
It&#;s normal to have some discomfort, swelling, and bleeding after getting a tooth pulled. If you don&#;t have any complications, your socket will likely heal within 10 days after the procedure.
If you think you may have an infection or dry socket, you should call your dentist right away. The dentist can diagnose and treat the issue.
Other signs that you should see your dentist include:
After you get a tooth pulled, a blood clot forms over the wound. Shortly after, your body starts to produce a delicate tissue called granulation tissue to fill the hole. This tissue often appears white.
If you aren&#;t experiencing pain, the white material you&#;re seeing in your socket is likely part of your body&#;s natural healing process. If the white tissue is accompanied with severe pain, you may have developed dry socket. If you think you may have dry socket, you should call your dentist right away.
