Brushing your teeth after eating - is harmful

Experts recommend brushing your teeth twice a day, but many people for reasons of hygiene brush their teeth after every meal, snacks and sugary drinks.

However, research has shown that brushing your teeth immediately after meals or beverages, especially acidic, can do more harm than benefit.

After the consumption of carbonated beverages and acid, the acid acts on the tooth enamel and to the layer beneath the enamel, called dentine. Friction toothbrush pushes the acid deeper into the enamel and dentin.

Dr. Howard Gamble, president of the Academy of General Dentistry in the United States conducted a study in which researchers followed the participants for three weeks, examining the impact of cleaning teeth after they drank a Diet Coke.

Scientists have found that brushing your teeth 20 minutes after a meal increased the level of damage to the dentin. The damage was much lower, if the person brushing his teeth in half an hour or an hour after meals.

To protect the surface of the dentin should wait at least half an hour before brushing your teeth.

Fruits, especially orange and lemon juice, vinegar, sweet carbonated drinks contain high levels of acid softened enamel. If you will wait at least 30 minutes to allocate enough saliva to neutralize the acidity.
