#11 Teeth: The Only Body Part That Cannot Heal On Its Own
Our teeth are covered by enamel – a tough protective layer of the hardest and most mineralised element in the human body. When corroded, the enamel gets repaired via minerals present in the saliva in addition to fluoride toothpaste.
However, in case of tooth decay, the enamel gets damaged beyond recovery and has to be fixed by a dentist by applying cavity fillings. Hence, it is imperative to take care of the teeth. Brushing twice a day and flossing are great ways to keep the teeth healthy.
