The fastest healing part of the body is the tongue. This is due to the rich supply of blood the tongue receives, making it able to heal twice as fast as any other part of the body. This includes taste buds, which is why someone can burn taste buds eating hot food and later be able to taste perfectly fine because the taste buds have quickly healed.
Another reason for the quick recovery of taste buds is that the mouth is constantly replenishing taste buds. Over a period of ten days, the tongue’s basal cells mature and regenerate, moving toward the top of the individual taste bud. Once it reaches the top, however, it only lasts a few hours before being washed away by saliva inside the mouth.
Actually, all areas inside the mouth heal faster than any other part of the body. The tongue is one of the most vascular organs in the human body. Because of this, the cells that participate in the healing process get to the injury quickly and in huge numbers. This creates a rapid regrowth of the tissue. Infection within the mouth is extremely rare because the enzymes in saliva kill most infectious materials. Most injuries inside the mouth require little or no treatment from a doctor, although that is not to say you should not seek medical attention in severe cases.
Most damage to the tongue caused by eating hot foods will be healed in two days or less, after which the individual sense of taste is also restored. Hot foods will rarely cause more than first-degree burns to the tongue, and only in the event of absolutely scalding liquid or food, such as hot oil or steam.
There have been cases of children biting their tongue almost in half and the wound began healing even before the doctor looked at it and was completely healed within a few days. People who have tongue piercings report that if they leave the piercing device out for more than a couple of days, even a few hours in some cases, the hole closes.
The tongue’s recovery time may be slowed down if the individual consumes citrus fruits and juices because they may exacerbate the existing damage to the tongue.
The human body is an amazing piece of machinery; no one can dispute that.
