Mouth wounds are faster in healing than the rest of the body, which is why!

It's saliva! It contains a molecule that can help grow new cells and repair damaged ones quickly. Scientists have found that saliva contains a peptide molecule called histatin-1 that fights bacteria and helps heal wounds faster than usual.

The study, published in FASEB, showed that Chilean scientists found a small molecule that helped heal wounds very quickly in a series of experiments. They added the histatin-1 molecule to fetal chicken cells and several types of human blood cells and blood vessels, and the result was amazing!

In order to heal the wound, new skin cells must form and then move from the edges of the wound gradually to cover the entire wound. Active fibroblasts help produce collagen, elastin and other proteins needed by the skin for restoration. The body also begins to reactivate the blood vessels, which strengthens blood flow to the wound and accelerates healing.

All the previous steps, Histatin-1 was found to be doing its job, helping to grow new blood vessels in the wound area. This compound, which is present only in human saliva, is the reason behind the healing of mouth wounds very quickly compared to the same wounds that are exposed to other parts of the human body!
