Apples Can Cause Four Times More Damage to Teeth than Sodas
Apples can cause up to 4 times more damage to teeth than sodas is one of the conclusions reached by a recent study looking at the effects of acidic foods and beverages on tooth decay.
Tooth Erosion and Decay
In a study on tooth erosion and decay published in the latest issue of the Journal of Dentistry, researchers studied the link between diet and tooth decay using over 1000 participants between the ages of 18 and 30. The participants were given a questionnaire about their past and present daily dietary habits and their teeth were examined for damage at the enamel and underlying dentine layer.
Comparing data from both diet and the level of tooth decay they observed, the researchers found that participants who reported eating apples were 3.7 times more likely to have damage to the dentine layer of tooth below the enamel while participants who consume carbonated drinks such as colas had no additional risk of tooth decay.
According to a statement made by one of the paper’s authors, Professor David Bartlett, Head of Prosthodontics at the Dental Institute, “'Doctors quite rightly say that eating apples is good, but if you eat them slowly the high acidity levels can damage your teeth. The drinks most often associated with dietary erosion, particularly cola, showed no increased risk in this study.”
The researchers also found that the likelihood of tooth erosion to the enamel near the top of the teeth near the gums increased by four times from drinking fruit juice and that lager raises the risk of dentine erosion up to three times. According to the researchers, apples, fruit juice and lagers owe their tooth-eroding properties to their acidity levels.
