According to Dr. Ryne Johnson, prosthodontist at Newton Wellesley Dental Partners, “Excessive amounts of fizzy drinks can damage teeth as badly as methamphetamine (meth) or crack cocaine, as cited in a paper published in General Dentistry”.

In the study Dr Mohamed Bassiouny, professor of restorative dentistry at the Temple University School of Dentistry in Philadelphia, says that meth, crack cocaine and fizzy drinks, whether sweetened or not, are all highly acidic and can cause similar dental problems. Cola and other carbonated drinks cause harmful bacteria to grow in the mouth. Although good bacteria are needed to break down the proteins in the foods we eat, too many bacteria can cause problems. Dissolved carbon dioxide is what gives soda beverages that popular fizz. When the gas is dissolved in water, it forms carbonic acid. Since bacteria are anaerobic, they thrive in environments with little or no oxygen. Bacteria use sugar for energy, after which the sugar becomes plaque, enabling bacteria to stick to tooth enamel, causing cavities over time.

The study highlights that the teeth of individuals addicted to meth or crack cocaine can be misdiagnosed as dental caries rather than generalized dental erosion, a condition that is also associated with chronic excessive consumption of fizzy drinks.

So, limit your intake of sugary drinks and remember to brush and floss regularly to avoid costly dental procedures. For additional information, visit
