DENTAL caries (better known as tooth decay) is a major public health problem globally and is the most widespread non-communicable disease. Dental caries is the breakdown of teeth due to bacteria (“Caries” in Latin for “rottenness”). A staggering 60 to 90 percent of children and nearly 100 percent of adults worldwide have or have had cavities, according to the World Health Organization. Teeth are constantly covered in a sticky film of bacteria called plaque. When a person consumes foods or drinks containing sugar, the bacteria in plaque creates acid that then attacks the hard outer layer of the tooth, destroying it over time.
Sweden has experienced dramatic declines in dental caries over the years. In 1968, roughly 20 percent of all 50-year-old Swedish women were toothless. In 1995, Swedish researchers recommended a new method of brushing teeth. By 2004, it decreased to only 0.3 percent, due to fluoride use and progressive dental health programmes. The scientific evaluation of the so called “high-fluoride toothpaste” showed it was 40 percent more effective in combating tooth decay compared with regular brushing. In 2004, a new brand of toothpaste was launched in Sweden with more fluoride than standard tooth paste. It leaves more fluoride in the mouth after brushing. Fluoride strengthens the enamel of the tooth by helping to rebuild enamel that has been attacked by acid, reversing signs of early tooth decay.
Brushing technique in Sweden, applicable for 12 years and above, is: 1. Use sufficient amount of fluoride toothpaste (about 2cm). 2. Brushing for two minutes making sure to cover all areas. 3. After spitting out the suds of toothpaste, do not rinse; if you do, use just a small amount of water. 4. No eating and drinking for 2 hours or at least 30 minutes after brushing. In Sweden, people visit dental clinics regularly for prevention of tooth decay.
