Acidic drinks and foods lower the pH level of the mouth so consuming those causes the teeth to demineralise. Drinks low in pH levels that cause dental erosion include fruit juices, sports drinks, wine, beer and carbonated drinks. Orange and apple juices are common culprits among fruit juices. Carbonated drinks such as colas are also very acidic.
While exposure to acidic foods, such as lemons, oranges and grapefruits don’t directly cause cavities, it weakens the enamel on your teeth, which can weaken teeth and make them more prone to decay.
One can minimize acid exposure by drinking juice in one sitting (not sipping for hours) and then avoiding other acidic foods and drinks for several hours.
Keep teeth strong by limiting extremely acidic foods.
