1. Read the following passage carefully and answer the questions that follow:

"Neemil Herbal" is natural, safe and delicious.

Made from Nature's finest ingredients, it comes with the goodness and fine taste of neem, clove, mint and many more herbs. It is the first and only toothpaste in India which does not contain fluoride and is completely safe if swallowed. It is ideal for children as they often forget to spit out the toothpaste while brushing their teeth swallowing toothpaste with fluoride may result in fluoride poisoning.

Dental fluorosis is caused when a child receives too much fluoride during tooth development. Fluoride poisoning causes white spots to appear on teeth and when it turns severe, teeth get badly stained or deformed. The critical period of exposure is between the ages of one and four. Fluorosis makes the surface of teeth rough and pitted. This makes cleaning difficult. Unclean teeth are more prone to decay. A decayed set of teeth affects self-esteem and leads to expensive dental work.

Studies show that fluorosis affects three out of every ten children who uses fluoride toothpaste. Research has shown that 70% of all fluorosis is caused when fluoride toothpaste is accidentally swallowed.
