Although the carbonated soda drink has been believed to be harmful to the teeth, but new research shows that more damaging to teeth biting an apple instead of drinking soda.Why is that?New research suggests that biting an apple four times more damaging to teeth compared with drinking carbonated beverages like soda. This is because the high acidity level and how to eat it.
"This is not just about what we eat, but how we eat it," explains Professor David Bartlett, Chief of prosthodontic at King's College London Dental Institute, penelitia leaders, as reported by Dailymail, Monday (10/10/2011).
Prof Bartlett said the apples are good for health but if you eat it slowly, then a high level of acidity in apples can merusakn teeth.
"The results emphasize that dietary advice should be targeted on the strength of the acid than some regular carbonated soft drinks," explains Prof. Bartlett.
In this new study, researchers looked for a relationship between tooth wear in some parts of the mouth and eating at more than 1,000 male and female participants ages 18 hingg 30 years.
Researchers look for damage to the 2 mm surface of the tooth enamel and dentin, the main supporting structure of the tooth under the enamel and compared with a strict diet.
Results showed that people who eat apples 3.17 times more likely to experience damage to the dentine, while those who drank carbonated beverages had no additional risk.
In addition to acid strength, the researchers said some of the apple contains 4 teaspoons of sugar that contributes to the growing levels of acid in the mouth.
"The fruit may contain acid and sugar levels clearly have, but people should not be desperate to eat fruit or fruit juice," explained Dr Glenys Jones, a nutritionist from the Medical Research Council's Human Nutrition Research.
Researchers gave some safe way to eat an apple, that is eating an apple with milk or a piece of cheese that contain calcium so as to neutralize the acid.
Drinking water immediately after eating apples may also help to wash away the danger of acid on teeth.
"Drinking fruit juices and smoothies through a straw is another way to protect your teeth. Brushing your teeth before eating acidic foods can also help because it provides a barrier between food and teeth," concludes Dr. Jones.
