TOOTHACHE

   Tooth decay is caused by bacteria that eats the sugar in your mouth. Everyone has *bacteria in their mouths. If these get a supply of sugar from sweet foods, they multiply and a substance called plaque is formed. The bacteria produces acids, which eat into the tooth, forming holes. These holes are called cavities. If the cavity is not filled by the dentist, it reaches the *pulp cavity and causes toothache. An infection may develop or the tooth may become loose if the gum is damaged.

   That is why you should brush your teeth after every meal, if possible. This helps to get rid of sugar and other food that is stuck in your teeth.

   It is also important to visit a dentist regularly. You can prevent cavities and gum disease by eating less sugar. Use a fluoride toothpaste when you brush your teeth as it will strengthen your teeth.

*bacteria - tiny organisms which cause disease.

*pulp cavity - the inner part of the tooth, which contains blood vessels and nerves.

SORE EYES (OR CONJUNCTIVITIIS)

   Sore eyes is an *inflammation of the conjunctiva, caused by bacteria or virus. The conjunctiva is the thin transparent membrane that covers the front of the eye to protect it.

   You can get sore eyes through contact. For example, if you were sharing towels with an infected person, you will probably get sore eyes. The virus will attack the conjunctiva, making it itchy and swollen. Then you will tear to wash the irritant away. But in the case of sore eyes, your tears cannot get rid of the virus.

   It is best to consult a doctor, who will prescribe eye drops. If you have a sore eye, don't rub it as it is likely to spread to the other eye. Don't forget to stay away from people as sore eyes is *infectious.

*inflammation - the reaction of a tissue when infected, resulting in swelling pain, redness and heat.

*infectious - easy to spread.
