Are human teeth poisonous?

In daily life, biting yourself with your teeth is a common phenomenon. In mild cases, it is just bruising or redness, swelling and pain caused by the teeth biting the oral wall when eating food; in severe cases, the trauma caused by the teeth may cause other infectious viruses or bring other diseases. Then some people ask whether our teeth are poisonous? In fact, teeth themselves are not toxic. The culprit that causes other diseases is oral bacteria. Let’s take a look with the editor below.

Are human teeth really poisonous?

In fact, human teeth themselves do not contain any toxins. Those who say that they are infected or "poisoned" after being bitten are because of the bacteria in the mouth. There are countless bacteria in the human mouth, both harmful and beneficial. These pathogenic bacteria will not cause disease to you under normal circumstances, but they are pathogenic bacteria to others. When bitten, the bacteria on the teeth enter the blood through the bite wound, thereby increasing the chance of transmission or infection. Therefore, the teeth themselves are not poisonous, but the bacteria attached to the teeth cause wound infection.

Besides, if human teeth were poisonous, wouldn't there be many people dying from tooth poisoning every day?

How poisonous are human teeth ?

However, the damage caused by teeth cannot be ignored. According to relevant data, the bite force of crocodiles' teeth is 2,000 kg, that of domestic cats is 200 kg, that of mantis shrimps is 150 kg, that of large dogs is 120 kg, and that of male humans is 45 kg.

The top area of ​​human canines is less than 1mm⊃2;. According to P=f/s, the pressure generated when a person bites is greater than 45Mpa, which is equivalent to 450 atmospheres, and it is easy to bite through the skin of the same kind.

Moreover, the appropriate temperature and humidity in the mouth, as well as food residues that have not been cleaned in time between teeth, have become a breeding ground for bacterial growth. The number of bacteria is greater than that of dogs, including many anaerobic harmful bacteria. When people bite others, bacteria enter the wound through the gaps between the teeth. Viruses contained in saliva may be transmitted through bites that cause bleeding, such as influenza, hepatitis, HIV, Ebola virus, etc.

What to do after being bitten ?

Step 1: Disinfection (clean the wound with 3% hydrogen peroxide, because the catalase in human blood decomposes the active oxygen produced by hydrogen peroxide and kills anaerobic harmful bacteria)

Step 2: Follow the doctor's advice and take oral or injected antibiotics for treatment

Step 3: Leave the wound open and do not rush to suture it. If there is suppuration, use Vaseline gauze to drain it.

Step 4: Get tetanus vaccine in time
