The outside white part of teeth is called the "enamel". The enamel is made of calcium phosphate and is very hard. Under the enamel is the dentine. The dentine is softer than the hard enamel. So it is hurt more by tooth decay (cavities). Under the dentine is the "pulp" which has the nerves and blood vessels that go to the tooth. This is the part that causes the pain of a toothache. "Cementum" is outside the dentine where there is no enamel. Cementum holds the tooth to the bone of the jaw.
If they are protected and kept clean, teeth should stay for a person's whole life. Many people lose their teeth early because they do not do the right things to keep teeth healthy.
Some things people can do to keep teeth healthy:
Plaque is the soft white substance that forms on teeth when they are not cleaned. It has bacteria in it that hurt enamel. If plaque is not cleaned off, after 2 days it can become tartar. Tartar is a hard substance that forms on teeth (mostly near the gums). Tartar makes gums unhealthy and makes more bacteria grow on the teeth.
Plaque is cleaned off with a toothbrush. If tartar forms on teeth, a dentist must clean it off.
The bacteria that are on teeth eat into the enamel. Cleaning and flossing teeth, eating good foods, and having a dentist take off plaque make less bacteria on teeth. If there is too much bacteria, they eat enamel faster than teeth make enamel. This makes holes in enamel called cavities. When a person gets cavities, he has the disease dental caries. Making cavities in enamel happens slowly. But once cavities go through enamel, the soft dentine is hurt much faster. Cavities may be fixed by dentists.

Deep Purple
Deep Purple are a rock band started in Hertford, England, in 1968. Their best known song is ""Smoke on the Water"" from the album "Machine Head". Some of their other albums like ""Deep Purple in Rock"" where a great hit and was rated #1 in Germany. Deep Purple are one of the pioneering bands and founders of the hard rock and heavy metal genre.
In 1967, a drummer called Chris Curtis was putting a new band together, where members would only be part of it when it suited them (or would "get on and off"). Because of this format, the band was called Roundabout. The first musicians to be hired were guitar player Ritchie Blackmore and keyboard player Jon Lord. Curtis behaved in a disorderly way, and so was fired from his own project. Blackmore and Lord wanted to continue, and so finished putting the band together themselves, with singer Rod Evans, bass player Nick Simper, and drummer Ian Paice. They renamed the band "Deep Purple" after a song Blackmore's mother liked, disliking the name "Roundabout".
This band lineup, known as "Mark I", released three albums, called "Shades of Deep Purple" (1968), "The Book of Taliesyn" (1968) and a self-titled (1969). They released a fairly popular single called "Hush", thought to be radio friendly in America, but, apart from that, did not have any success. Eventually, Blackmore and Lord decided to change the style of music the band would play from soft progressive rock to hard rock. While Ian Paice agreed to the change, they decided Evans and Simper would not fit this new style, and were let go from the band.
The band found a new singer called Ian Gillan and a new bass player called Roger Glover, forming Mark II. Jon Lord used to play in orchestras, and at this time, wanted to go back to them and base the Deep Purple sound around that. Whilst the band did perform as an orchestra (with new singer Ian Gillan writing lyrics) gaining the band some publicity, Gillan and Blackmore were not happy about the band being associated with orchestras, and were firm about Deep Purple being a hard rock band, though Jon Lord would write another orchestral piece for the band.
The band eventually got back to their plans of playing hard rock, and released "Deep Purple in Rock" in 1970, which became a big success. The famous album cover shows the band members' faces engraved into Mount Rushmore. The album itself had popular songs such as "Speed King" "Child in Time" and "Bloodsucker" (which was later re-recorded by the band in 1998). Critics and fans were pleased with new singer Ian Gillan's high pitched singing and screaming, and the album has since been considered a classic of the time, along with Black Sabbath's "Paranoid" and Led Zeppelin's "Led Zeppelin II".
The band followed "In Rock" up with "Fireball" in 1971, which did show hints of creative progressive rock but was still as heavy as the last album. Just weeks later, the band started working on the next album, which would become "Machine Head". An incident at a Frank Zappa & the Mothers of Invention concert would inspire the band to write their most popular song, "Smoke on the Water" which ended up on the album. "Machine Head", released in 1972, was another success and featured several other popular songs like "Highway Star" and "Space Truckin'".
Mark II's last album was "Who Do We Think We Are" in 1973, and it featured another hit song for the band, "Woman from Tokyo". Ian Gillan left the band that year as he did not like the band's touring and recording schedule, because at the time he wanted a break. He was also arguing with Ritchie Blackmore. Roger Glover left shortly after, also because of arguing with Blackmore.
David Coverdale and Glenn Hughes were hired to replace Ian Gillan and Roger Glover. Glenn Hughes also had singing talent so it was decided he would act as lead singer on some of the band's songs too. In fact, since Hughes was hired first, the band considered performing as a 4-piece from then on, with Hughes singing full-time as well as playing bass.
Mark III's first album, "Burn", released in 1974, was successful and seemed to point a positive picture for the band's future without Gillan or Glover. The singing harmonies from Coverdale and Hughes had something of a blues and funk style to them. These styles were explored more on the band's next album, "Stormbringer", released later the same year. Ritchie Blackmore left after he became more unhappy with this style of music, feeling it was just "shoeshine music".
