Sugar is well known to cause cavities, but diet pop is also harmful to teeth. While sugar-free drinks do not contribute to tooth decay in the same way as sugar, they often contain phosphoric, citric, and tartaric acids that damage teeth. These acids weaken tooth enamel, lowering the threshold for bacteria to start a cavity. This means it is easier for the bacteria to cause cavities, and they can do it faster in an acidic environment. As such, diet pop can cause tooth decay and gum disease, just like regular pop.

What You'll Learn
Sugar-free drinks can still cause cavities
Sugar-free drinks are often thought to be a healthier alternative to their sugary counterparts, but they can still cause cavities. While it is true that sugar can lead to tooth decay, it is not the only cause of cavities. The misconception that sugar is the only cause of cavities is deeply ingrained in our brains, as parents and caregivers have warned against the dangers of too much candy. However, the cavity-causing process is multifaceted.
Sugar-free drinks, such as diet sodas, are highly acidic and can cause dental erosion. They contain ingredients such as phosphoric acid, citric acid, and tartaric acid, which damage teeth. As you sip these drinks, ongoing acid attacks weaken tooth enamel, causing decay over time. This is known as dental erosion, which strips away the tooth enamel, exposing the soft and sensitive insides of the tooth. The lower the pH of a food or drink, the higher the risk for tooth erosion.
Additionally, while sugar-free drinks do not contain sugar, they often contain artificial sweeteners, which can break down into acids in the mouth. These acids bore holes into your teeth, weakening them over time. This process is similar to how acids act on wood. The more you drink these sugar-free drinks, the weaker your teeth become.
Furthermore, sugar-free drinks can also contain caffeine, which can be detrimental to oral health. Caffeinated beverages dehydrate the mouth and reduce saliva production. Saliva plays an important role in protecting your teeth and gums, so a decrease in saliva makes your teeth more susceptible to damage.
To summarize, while sugar-free drinks may seem like a healthier option, they can still cause cavities and tooth decay. The high acidity of these drinks can lead to dental erosion, and the artificial sweeteners can break down into acids that weaken teeth. Caffeine in these drinks can also reduce saliva production, further compromising oral health. Therefore, it is important to be mindful of the potential risks associated with sugar-free drinks and to practice good oral hygiene to maintain healthy teeth and gums.

Acidic drinks erode tooth enamel
Sugar-free drinks like diet sodas are often believed to be better for oral health than their sugary counterparts. However, this is a misconception. While sugar is indeed bad for your teeth, acidic drinks like diet sodas can also damage your teeth by eroding the tooth enamel.
Phosphoric acid, citric acid, and tartaric acid are some of the ingredients in diet sodas and fruit juices that can weaken and erode tooth enamel. The more weakened the enamel, the easier it is for bacteria to cause cavities. This is why it is important to limit your intake of acidic drinks.
The Wisconsin Dental Association states that "as you sip, ongoing acid attacks weaken tooth enamel, causing decay over time". This is especially true if you sip on acidic drinks throughout the day, as your teeth are kept in an acidic environment for hours at a time.
To protect your teeth, you can try to reduce the number of acidic drinks you consume and opt for other choices like water, unsweetened tea, milk, plain sparkling water, and diluted juice, all of which have little to no sugar or acid. You can also practice good oral hygiene by brushing your teeth regularly and removing dental plaque to lower your cavity risk.

Bacteria in the mouth cause cavities
Sugar is known to cause cavities, but it is not the only thing to blame. Cavities are an infectious disease caused by bacteria in the mouth. These bacteria are very tiny—only 1/500th of a human hair in width—but they can cause significant damage to teeth.
The bacteria in the mouth convert sugars and starches into acids through a process called fermentation. These acids dissolve the hard tissues of the teeth (enamel, dentin, and cementum), causing cavities. The most common bacteria associated with cavities are mutans streptococci, including Streptococcus mutans and Streptococcus sobrinus, and lactobacilli. These bacteria are present in dental plaque, which adheres to the teeth and gums. Poor oral hygiene allows plaque to remain on the teeth, giving bacteria a chance to cause damage.
Consuming sugary drinks, such as soda, can increase the risk of cavities by attracting bacteria that decay tooth enamel. However, diet sodas are also harmful to oral health. They contain acids such as phosphoric acid, citric acid, and tartaric acid, which can weaken tooth enamel and lead to erosion. This softening of the enamel lowers the threshold for bacteria to start a cavity, making it easier for them to cause cavities.
To reduce the risk of cavities, it is important to practice good oral hygiene, including brushing twice a day with a soft-bristled toothbrush, using antimicrobial toothpaste containing fluoride, and flossing once a day. Additionally, it is recommended to limit the consumption of sugary and acidic drinks, as they contribute to the formation of cavities.
In summary, while diet pop itself may not directly cause cavities, it contributes to an acidic environment in the mouth that makes it easier for bacteria to cause cavities. Therefore, maintaining good oral hygiene and reducing the consumption of acidic and sugary beverages are crucial in preventing cavities.

Sugar feeds cavity-causing bacteria
While it is true that sugar-free drinks decrease your risk for tooth decay, they do not remove the risk entirely. Sugar-free drinks such as diet sodas contain phosphoric, citric, and tartaric acids that can damage teeth. In fact, diet sodas cause about the same amount of dental erosion as regular sodas.
Cavities are an infectious disease caused by bacteria. The bacteria live in dental plaque, which adheres to the teeth and gums. When plaque is not cleaned from the teeth, the bacteria remain in contact with the tooth, increasing the chance of causing damage. Sugar feeds the bacteria, which then produce acid as a by-product. This acid weakens tooth enamel, causing decay over time.
The two destructive bacteria found in the mouth are Streptococcus mutans and Streptococcus sorbrinus. They feed on the sugar you eat and form dental plaque, a sticky, colourless film that forms on the surface of the teeth. If the plaque is not washed away by saliva or brushing, the environment in the mouth becomes more acidic and cavities may form.
The more frequently you consume sugar, the higher your risk of developing cavities. Sticky foods such as hard candies, breath mints, and lollipops are linked to tooth decay because they provide a long-lasting source of sugar. This gives the bacteria in your mouth more time to digest the sugar and produce acid.

Saliva counteracts the acid in diet soda
Sugar-free drinks like diet soda can be surprisingly bad for your teeth. While it is true that sugar can lead to tooth decay, it is not the only thing that can cause cavities. The cavity-causing process is multifaceted.
Diet sodas contain phosphoric, citric, and tartaric acids, which can damage teeth. As you sip, ongoing acid attacks weaken tooth enamel, causing decay over time. This softening of the enamel lowers the threshold for bacteria to start a cavity, making it easier and faster for them to cause cavities in an acidic environment.
Saliva is a mild base and can counteract the acid in your diet soda. Saliva is slightly alkaline, or just above neutral on the pH scale, and it breaks down acids. When you eat food, your body increases saliva production. So, drinking soda with a meal lowers its impact on your teeth. Chewing sugar-free gum stimulates the production of more saliva, so if you drink a soda between meals, you can quickly counteract it by chewing gum. However, it must be sugar-free, as the bacteria that cause cavities feed on sugar.
To reduce the risk of cavities, it is best to avoid sodas altogether. However, if you do choose to consume soda, it is better to drink it during mealtimes. After drinking a soda, you can also quickly rinse your mouth with plain tap water to neutralize the pH and flush away any lingering soda between the teeth.
