The enamel is the thin outer coating of the tooth. The tough shell is the toughest tissue in the human body. Enamel covers the crown of the tooth, which is visible outside of the gums. Enamel protects your teeth from the regular wear and tear of eating, biting, crunching, and grinding. Enamel, despite its toughness as a barrier between teeth and the outside world, can chip and crack. Enamel also serves as a barrier between the teeth and potentially harmful chemicals and temperatures. Because hot or cold meals, drinks, and sweets can reach the nerves inside your mouth through holes in your enamel, you may notice that you react more to them as your enamel erodes. To avoid teeth problems, schedule a dental checkup with Dr. Sanket, a dentist in Ghatkopar.
