Acidic foods can be quite harmful to your teeth because they erode your tooth enamel.  The enamel n your teeth is a strong, protective coating that helps to prevent decay.  Once the enamel is softened and eroded, you can't get it back and your teeth become more vulnerable to decay.

The saliva in your mouth is meant to neutralize acid.  However, continually consuming sugary foods such as soda, cookies and fruit juices causes excessive amounts of acid to form in your mouth and increase the possibility of tooth enamel erosion.  Dentists recommend that your reduce the amount of soft drinks, sports drinks and fruit juices you drink to minimize tooth enamel erosion.  If you cannot brush your teeth after eating a sugary snack, rinse with water for 30 seconds to remove some of the sugar left behind.  The best way to remove sugary debris is to brush your teeth with an ADA approved fluoride toothpaste after snacking.  You should brush your teeth at least twice a day for two minutes.  Also, daily flossing is imperative to remove the particles that get stuck in between your teeth and may cause enamel erosion.

Remember to schedule routine visits to your dentist's office for checkups and professional cleanings.  A professional cleaning can help to remove stubborn plaque and tartar that compromises the enamel on your teeth.  Additionally, your dentist will be able to detect early signs of decay to keep them at bay.

The best way to keep your teeth healthy is to avoid acidic foods, eat healthy snacks, brush and floss regularly and visit your dentist for routine checkups.
