Wounds can occur inside the mouth for many reasons, including accidents and surgical procedures. No matter the cause of the wound, the body will begin to heal it. Granulation tissue, which forms on the wound, plays an important role in the healing process.
The Wound Healing Process
Wounds inside the mouth heal in essentially the same way as wounds in any other part of the body, explains an article published in Frontiers in Physiology. First, a blood clot forms in the wound, which serves to seal the wound. Nearby blood vessels constrict to stop the bleeding. The immune system then works to remove debris, damaged tissues and microorganisms from the wound.
After those initial steps, granulation tissue starts to form in the wound. This very fragile tissue consists of small blood vessels, white blood cells and other connective tissue cells containing collagen, a protein that provides a foundation for new tissue growth.
Cells from the edges of the wound move across the wound surface in a process known as epithelialization. These cells work to eventually close the wound. As the healing process concludes, a scar may be left in the area.
Role in Oral Health
Granulation tissue plays a key role in the healing process and helps protect the wound from further damage. It is especially important in the case of larger wounds, like those left by tooth extractions. When a tooth is extracted, granulation tissue forms after about one week, according to the Frontiers in Physiology article. It protects the extraction site until the new bone can form, which takes about eight weeks.
During gum flap surgery, a specialist called a periodontist separates the gum tissue from the teeth and often removes granulation tissue in the process. This is intended to facilitate healing and reduce chances of infection. However, a study published by the Swiss Dental Journal found that granulation tissue may contain stem cells that could aid in repairing the gums. Removed or not, this tissue is a powerful product of your body that supports your health and ability to recover from injury.
Signs an Oral Wound Isn't Healing Properly
Wounds inside the mouth tend to heal more quickly than wounds elsewhere on the body, reports an article in Science Translational Medicine. Despite this, oral wounds can sometimes heal improperly. While granulation tissue promotes healing, if too much of this tissue forms in a wound, it actually slows the healing process. The healing process can also be halted if a wound bleeds excessively and the tissue isn't able to form properly.
The development of pus and a bad smell from the wound are also signs that your wound is healing abnormally. If you're concerned about an oral wound, talk to your dentist.
Oral Hygiene With a Mouth Injury
It can be hard to stick to your regular oral hygiene routine when you have a wound inside your mouth. However, brushing and flossing are still important during this time. Your dentist can provide advice on how to clean your teeth without disturbing the wound. For example, if you've had a tooth extracted, you should avoid cleaning the affected area until healing has begun, but you can brush and floss all the other teeth.
Wounds inside the mouth can be uncomfortable, but they generally heal quickly. If you have a wound inside your mouth, follow your dentist's care instructions.
