We are often asked if white wine is less likely to stain the teeth than red wine. The latest studies indicate that white wine may be just slightly less likely to cause staining than red wines. Researchers at New York University College of Dentistry have found that the acidity of wines, in general, are the principal factors leading to increased levels of tooth staining, compared to plain water. The acids in both red and white wines, as well as other beverages, such as sodas which also may contain citric or phosphoric acids, lead to creating pitting and rough spots in the enamel surfaces. These micro-imperfections allow the stain molecules from foods and beverages to penetrate deeper into the tooth enamel. However, red wine contains chromogen, which is a strongly pigmented molecule, so it tends to leave a deeper discoloration. The conclusion of the researchers was that it is not necessary to totally eliminate red wines from our diet in order to keep our teeth white, but it is advisable to cut back. It is important to note that many of the flavored waters and most of the sports and energy drinks on the market contain significant levels of acids. Although we consider natural orange and grapefruit juices and other citrus fruit juices as healthy, they all contribute to the acidic erosion of tooth enamels and root surfaces.

At your next dental hygiene visit, ask whether your teeth show any signs of acidic erosion of your enamel, and seek early intervention before the problem becomes widespread. Often, a change in dietary habits along with efforts to re-mineralize the affected areas can arrest the progress of this problem.
