'French kiss warning' issued ahead of Chinese Valentine's

TAIPEI, Taiwan -- A French kiss may involve a swap of millions of bacteria that could harm one's oral hygiene, a dentist warned yesterday ahead of the upcoming Chinese Valentine's Day.
Huang Yao-hui, vice chairman of Taiwan's Association of Family Dentistry, said a previous study has shown that a typical French kiss will result in a swap of 250 kinds of bacteria between the kissers.
Huang said 1cc of saliva contains more than 100 million bacteria, including those that cause dental problems.
The dentist suggested lovers maintain good oral hygiene before spending Seventh Eve — the Chinese Valentine's Day on the seventh day of the seventh month on the lunar calendar. It falls on Tuesday this year.
Huang said people should brush their teeth twice a day with fluoride toothpaste, and have their teeth examined by dentists every six months.
