Pure, white teeth are very rare. These days, models and actor-actresses, even common people regularly opt for teeth whitening methods. The natural color of our teeth is slightly yellowish and not pure white. The yellowness varies from person to person. Yellow teeth causes can be extrinsic (caused by external factors) or intrinsic (caused by internal factors). With proper care and hygiene, you can maintain the original color of your teeth.Causes

Exercise 4. Read and translate the text.
Prosthetics is the branch of dentistry concerned with the replacement of missing teeth by dentures, in order to restore normal appearance and function.
When there are no teeth left in a jaw, it is said to be edentulous and the artificial replacement is called a full denture; if some teeth are still present the replacement is called a partial denture.
If a tooth is extracted, and not replaced artificially, the opposing tooth has nothing to bile on and is therefore functionless. Having no opposition, it overerupts and loses masticatory quality. It consequently becomes a food trap which produces localized gingivitis and caries. Furthermore the two teeth on either side of the missing one tilt towards each other and form additional food traps. Thus the loss of a single tooth can give rise to caries and periodontal disease in at least three other teeth.
If several teeth are missing, mastication cannot be performed efficiently and this may lead to digestive disorders and even malnutrition. In addition the whole force of mastication is borne by the few remaining teeth; and if periodontal disease is already present it will certainly be aggravated by this excessive stress.
Therefore it is essential to replace missing teeth as soon as possible, with a denture or bridge, in order to prevent these arising dental and digestive disorders.
Dentures are made in the dental laboratory on models of the jaws produced by pouring Plaster of Paris into an impression of the patient’s jaw. The impression is filled with impression material and held in the mouth till set. The models are then returned to the laboratory where they are mounted on an articulator and the stage of correction and alteration take place. Then the teeth are embedded in wax. After that the finished denture is made and finally it is fitted in the surgery.

This article was frightening as well as uplifting to me. What was
frightening to me is the fact that in the US these disturbing rituals take
place. As I already stated as an outsider it is very difficult trying to make
sense of these customs in terms of my society.I was being quite ethnocentric. It
took me a while to get my stomach back and realize that these people are born
into this lifestyle. These rituals are apart of the religion they hold dear to
there heart. So yes, to the common white Irish Catholic this may be peculiar,

but after some time it occurred to me, the beauty in such strong religious
devotion. The Nacirema go to great lengths to, in there minds cleanse the unholy
body. Although it may turn your stomach as well as mine, I believe we should be
cultural relativist, step back and respect such deep faith and belief. I also
believe there is a lesson to be learned here. For if our society as a whole
upheld and blindly excepted the teachings of our respected religions, we would
liv e in a safer and better educated society than we do today.

Are your pearly whites decidedly grey? There's a bewildering choice of ways to brighten your smile without resorting to expensive dental surgery treatments. They certainly won't offer bleach-bright Hollywood results but do the trick if years of coffee and vin rouge have done their worst. Here's our choice of the simplest and most effective at-home tricks and treatments for a glowing grin.
1. Pearl Drops Pure White Whitening Treatment: £25, Amazon
This one is simple-to-use. Brush with your normal toothpaste then paint the brightening serum over teeth and leave for half a minute. Next, paint on the activator to work for a further 30 seconds and finish off by brushing with the included toothbrush and polish. Our tester was delighted with results even after five days; half the recommended treatment time.
2. Philips Sonicare DiamondClean Pink: £130, Amazon
With its special whitening function of 31,000 brush strokes per minute, this sonic wonder gave remarkable results with ordinary fluoride toothpaste. Our tester reported a rather pleasing 'just paid a fortune at the hygenist' feeling to boot. Not cheap, but look out for discounts at major retailers such as Amazon and Argos - often 50% or more. Also available in white or black.
3. Rapid White Dissolving Tooth Whitening Strips: £20, Amazon
Dab on the accelerator lotion then peel off jelly-like strips from the film and apply to the teeth. They'll dissolve in 5-7 minutes and in that time you'll feel like you're grinning through a coating of lemon and mint chewing gum. Rinse and go - these are simple and effective if you want a minimum of fuss (though the strip sachets can be fiddly to open).
4. Diamond Whites Home Whitening Kit: £40, Amazon
Put the plastic mouth trays in boiling water for half a minute then remove and bite down to customise your mould. After a brush with the activator spray, fill the moulds with gel and leave for 30-45 minutes. Can be a drool-fest but used with the follow up whitening pen included in your kit, results are good.
5. iWhite Instant: £23, Amazon
These pre-filled gumshield-style trays contain a gentle, peroxide-free whitening gel to be used over the course of five days. A 20-minute treatment time followed by a swoosh around with water means it's all pretty simple, but expect effective stain removal rather than megawatt brightening. Slightly shallow trays mean this treatment is best for those without a tombstone grin.
6. Luster Premium White Pro Light: £43, Amazon
Uses light to boost the effectiveness of the treatment. Pre-treat the teeth with the whitening solution, add activator then hold the lamp over the exposed teeth for two minutes. Can take up to 20 daily treatments for maximum results, but persevere for a winning smile.
Thinking long-term, the Philips Sonicare DiamondClean is a real investment. Never has a toothbrush been so effective. Buy brush heads for all the family (from around £25 for four from Amazon ) and you'll be fighting over it. The Pearl Drops kit tastes more pleasant than others we tried, is straightforward and, most importantly, works. Our Americano-loving tester's teeth showed a noticeable improvement in less than a week. Our budget winner.
