Drinking large quantities (2 liters per day) of soda can be as damaging to your teeth as methamphetamine and crack cocaine use, according to a new study in the journal General Dentistry.
The study compared tooth damage from methamphetamine, cocaine, and diet soda. The participants in the study all admitted to having poor oral hygiene and not visiting a dentist on a regular basis. The researchers found the same type and severity of damage from tooth erosion in each participant's mouth.
"Each person experienced severe tooth erosion caused by the high acid levels present in their 'drug' of choice - meth, crack, or soda," said Mohamed A. Bassiouny, lead author of the study. "The citric acid present in both regular and diet soda is known to have a high potential for causing tooth erosion."
Similar to citric acid, the ingredients used in preparing methamphetamine include corrosive materials, such as battery acid, lantern fuel, and drain cleaner. Crack cocaine is also highly acidic in nature.
"The striking similarities found in this study should be a wake-up call to consumers who think that soda - even diet soda - is not harmful to their oral health," concluded Bassiouny.
