answer:Gum tissue is very delicate. If you take the end of your fingernail and press firmly for about 10 seconds, you’ll feel pain. Think back to the last time you had an infection or inflammation; the pain was probably so bad that it distracted you from focusing on anything else. Given all that, the process of teething – items slowly twisting, shifting, and emerging – must be miserable. Ouch. By the way, teeth don’t actually cut through flesh. The body releases special chemicals that cause some gum cells to die and the tissue to separate, allowing teeth to erupt. Still, though, the baby’s gums are very swollen and sensitive, and teething’s a traumatic ordeal.
