"CH-E-E-S-E," the photographer orders, to get a big, shining smile. If your teeth are clean and white, the smile is artless and perfect.
We have been preparing to show our healthy teeth since we were kids, when mum urged us to use the colourful toothbrush with cartoon figures every morning and night.
Brushing teeth has become part of our life, but there are some parts of the teeth that are unreachable by the brush, particularly between teeth.

The small amounts of food left in these hard-to-reach locations day after day interact with bacteria in the mouth and become mineralized to form tartar.
Tartar forms on the surface of teeth, and can cause diseases like gingivitis and periodontal disease.
Tartar forms on the surface of teeth, and can cause diseases like gingivitis and periodontal disease.
Gingivitis starts in a small area and, if not checked, spreads to cover the whole periodontal area. It may damage the alveolar bone and cause atrophy of the gums.
To prevent such diseases, tartar should be removed regularly and professionally. The toothbrush is no longer useful because the tartar is closely attached to the teeth.

"We recommend most customers to have their teeth cleaned, " said an assistant in a local beauty saloon.
The service is specially welcomed by men who have ugly stains due to heavy smoking, she added.
However, dentists warn that unsanitary teeth cleaning methods in clinics without licenses or in beauty saloons may be dangerous, and can become a source for the transmission of viruses.
Even a minor abrasion in the mouth will allow infections to enter the body. Diseases such as hepatitis B and AIDS are only two of them.
Patients with infectious diseases who come to a hospital to have their teeth cleaned must get special treatment. Any patient with acute oral inflammation must wait until it heals before having their teeth cleaned, to avoid transmitting infection.
However, these steps are mostly omitted in beauty saloons, because their staff have no formal medical training and do not realize the importance of these precautions.
Another danger in beauty saloons comes from the doubtful sterilizing process for teeth-cleaning equipment.

One virus carrier with oral inflammation can cause infection in all of the customers following him or her if the instruments are not strictly sterilized
The improper use of ultrasonic during tooth washing may even damage the smooth surface of tooth, and tartar is easily formed on the rough teeth surface.
Dentists suggest that teeth should be cleaned every three to six months to keep them tidy and healthy. They also recommend that the procedure be done by a dentist for safe and professional service.
