Most people are aware that sugary foods and beverages can promote tooth decay. It is also true that acidic beverages like soda and sports drinks can damage tooth enamel. It should also be remembered that any acidic beverage, including wine, can cause erosive damage to your teeth. The exposure to acid causes the PH on the tooth surface to drop. Before eating or drinking, the PH in the mouth is about 6.2 to 7.0, slightly more acidic than water. At a PH of 5.2 to 5.5 of below, the acid begins to dissolve the hard enamel that forms the outer coating of our teeth. The PH of wine is between 3.0- 3.8, and white wine is more acidic than red. A few minutes of sipping wine can cause damage to the enamel of your teeth.

Damage from acidic erosion of the teeth makes the teeth appear smooth and almost glazed. Continued erosion will expose the underlying dentin which has a yellowish appearance. At this point, the teeth can become very sensitive and often require fillings, crowns, or veneers to repair the damage. Teeth with severe erosion may require root canal.

The easiest way to prevent cavities is by brushing your teeth at least three times a day, especially after eating and before bed, and flossing once a day. You should brush with a soft bristled toothbrush, and angle the bristles about 45 degrees toward the gum-line. Brush for about the length of one song on the radio (3 minutes) using a fluoride containing toothpaste. It's also a good idea to ask your dentist or hygienist to help you with proper brushing methods.

Reducing the amount and frequency of eating sugary foods and drinks can reduce the risk of forming cavities. If you are going to drink wine or a can of sweetened soda, it is better to drink it in one sitting, than sip it throughout the day. If you can't avoid soda or acidic sports drinks, consider drinking it through a straw in one sitting, to bypass the teeth altogether. Getting to the dentist at least twice a year is also critical for examinations and professional cleanings.
