### Aspartame and Dental Health Aspartame is a low-calorie sweetener used in many diet foods and drinks. It is 200 times sweeter than sugar, so only a small amount is needed to achieve the desired sweetness. Aspartame is made from two amino acids: aspartic acid and phenylalanine. These amino acids are naturally found in many foods and in the human body. #### Safety of Aspartame Aspartame has been extensively studied since its development in 1965. Most health authorities, including the FDA and the World Health Organization, consider it safe to consume in moderate amounts. For example, a person weighing 150 pounds can safely consume up to nine cans of diet soda containing aspartame per day. #### Aspartame and Dental Health One of the benefits of aspartame is that it does not contribute to tooth decay. Unlike sugar, aspartame does not provide food for the bacteria in your mouth that cause cavities. Therefore, consuming foods and drinks with aspartame instead of sugar can be better for your dental health. #### Potential Risks While aspartame is generally considered safe, some people may experience side effects if they consume it in large amounts. These can include mood swings, skin problems, and even potential kidney and liver damage over long-term, high-level consumption. People with phenylketonuria (PKU), a rare genetic disorder, should avoid aspartame because their bodies cannot process phenylalanine properly. #### Alternatives to Aspartame If you are concerned about aspartame, there are other low-calorie sweeteners available, such as stevia, sucralose, and monk fruit extract. These alternatives are also considered safe and do not contribute to tooth decay. In summary, aspartame is a widely used low-calorie sweetener that is generally safe for most people and does not harm dental health. However, it is always a good idea to consume it in moderation and consider other sweetener options if you have specific health concerns.
