Drinking fizzy drinks (Soft drinks) increases the risk of tooth decay as it damages the tooth enamel due to the high content of acid, sugar and starch which increases risk of tooth decay which cannot be repaired if affected. The Mayo clinic has reported ways by which tooth decay due to fizzy drinks can be reduced.
Using a straw can reduce the risk of enamel damage, make sure the straw is positioned to the inside of the mouth which reduces the contact between soda and enamel which, reduces the risk of enamel damage.
• Don't brush your teeth immediately after a drink as the acid in the drink damages the tooth but you can rinse your mouth.
• Avoid holding the drink for a long time in the mouth swallow the drink as soon as you take it.
• Use a fluoride containing toothpaste.
• Brush your teeth twice a day to reduce plaque and tooth decay.
