How Sugar Causes Tooth Cavities and Ruins Your Teeth

As a kid, you may be familiar with the saying, "too much candy will rot your teeth"., Most of us are now aware that sugar has an impact on dental health. The culprit is not sugar on its own. Instead, the chain of events that takes place afterwards is to blame. The chain effect caused by consuming sugary or acidic food and beverages eventually leads to dental caries.

This short article shows how sugar affects your teeth and how you can protect your teeth against dental cavity.


Your Mouth Is a Battleground

We call it a battleground because many different sorts of microorganisms stay in your mouth. Some are beneficial to your oral wellness, while others are damaging.

Studies have revealed that some harmful bacteria generate acid in your mouth whenever they encounter and digest sugar. These acids get rid of minerals from the tooth enamel, which is your tooth's glossy, protective outer layer. This process is called demineralization.

The good news is that your saliva assists in regularly reversing these damages in a natural process called remineralization.

The minerals in your saliva, such as calcium and phosphate, along with fluoride from toothpaste along with water, aid the enamel in repairing itself by replacing minerals lost throughout an "acid attack." This helps enhance your teeth.

Nonetheless, the repetitive cycle of acid strikes triggers mineral loss in the enamel. Over time, this deteriorates and damages the enamel, forming dental caries.

A cavity is a hole in the tooth caused by dental caries. It's the outcome of hazardous microorganisms digesting the sugar in foods and creating acids. If left unattended, dental caries can spread out right into the much deeper layers of the tooth, causing discomfort and possible tooth loss.

The symptoms of dental caries include tooth pain, pain when chewing, and a level of sensitivity to pleasant, warm or cool foods and drinks.

In Short:

Your mouth is a consistent battleground of demineralization as well as remineralization. However, cavities occur when germs in your mouth absorb sugar and create acid, compromising tooth enamel.

Sugar Attracts Bad Bacteria and also Reduces Your Mouth's PH.


Sugar is like a magnet for harmful microorganisms

The two damaging microorganisms located in the mouth are Streptococcus mutants and Streptococcus sobrinus. Both of them absorb the sugar you consume and form dental plaque, a sticky, colorless element that forms on the surface area of the teeth.

If the plaque is not gotten rid of by saliva or brushing, the atmosphere in the mouth becomes a lot more acidic, and tooth cavities may start to develop. The pH scale gauges just how acidic or fundamental a remedy is, with seven being neutral. When plaque pH drops below regular or less than 5.5, the level of acidity starts to dissolve minerals and destroy the tooth's enamel.

While doing so, small holes or erosions will undoubtedly be created. In time, they will certainly become more extensive till one large opening or cavity shows up.

In Short:

Sugar draws in damaging microorganisms that ruin the tooth's enamel, creating dental caries in the influenced tooth.


Nutritional Behaviors That Cause Tooth Decay

In recent years, researchers have found that certain food behaviors matter when it comes to forming cavities.

Consuming High-Sugar Snacks

Think about your oral health from now before you grab that sweet snack. Many research studies have discovered that the frequent intake of sugary foods and sweet drinks leads to dental caries. Constant snacking on foods high in sugar increases the quantity of time your teeth are revealed to the dissolving impacts of different acids, triggering tooth decay.

For example, one current study amongst school children discovered that those who snacked on cookies and potato chips were four times more likely to develop dental caries than children who did not.


Drinking Sweet and Acidic Beverages

One of the most usual resources of fluid sugar is sweet soft drinks, sports and energy drinks and sweet juices.

In addition to sugar, these beverages have high levels of acids that can create tooth decay.

In extensive research in Finland, researchers concluded that people consuming sugar-sweetened drinks daily were prone to a 31% higher threat of cavities.

Likewise, an Australian study suggested that kids aged five years to sixteen years consumed a variety of sugar-sweetened beverages and sugar-sweetened food, which directly correlated to the array of cavities found in their oral system.

What's even more, one research study involving more than 20,000 adults showed that just one occasional sugary beverage led to a 44% rise in the risk of shedding 1-5 teeth, compared to those who did not consume alcohol or consumed any sugary drinks.

This implies that consuming alcohol, a sugary beverage greater than two times a day, almost triples the danger of losing more significant than six teeth.

Fortunately, one research discovered that minimizing your sugar intake to less than 10% of daily calories lowers your danger of dental cavities.


Eating Sticky Foods

"Sticky foods" are those that provide durable sources of sugar, such as hard candies, breathe mints and lollipops. These are additionally linked to the dental cavity.

Because you keep these foods in your mouth for longer, their sugars are slowly launched. This offers the hazardous bacteria in your mouth plenty of time to absorb the sugar and create even more acid.

The end outcome is extended durations of demineralization and the shortened duration of remineralization. Also, refined, starchy foods such as potato chips, tortilla chips, and flavored biscuits may linger in your mouth and trigger dental caries.

In Short:

Certain practices are directly related to tooth decay, such as snacking high-sugar foods, consuming sugary alcohol or other acidic beverages, drinking carbonated drinks, and consuming sticky foods.


Tips to combat Dental Caries

Research study has discovered that variables can quicken or slow down the growth of cavities, as well. These consist of saliva, eating behaviors, direct exposure to fluoride, dental health and total diet.

Below are some methods you can fight tooth decay:

Consume Smart

See to it to consume a balanced diet plan abundant in entire grains, fresh fruits, vegetables, and milk items. If you consume sugary foods and sweetened or acidic beverages, have them with your meals, as opposed to between them.

Likewise, think about using a straw when consuming sweet and also acidic beverages. These subtle consumption techniques will offer your teeth much less direct exposure to the sugar and acid in the drinks.

In addition, add raw fruit or vegetables to your meals to raise saliva flow in your mouth. Ultimately, do not enable infants to copulate containers including sweetened fluids, fruit juices or formula milk.


Lower Sugar

Sugary and sticky foods must just be avoided or at least has to be under a limit. If you enjoy sweet treats, ensure you consume some water after consuming any sugary or sticky food- Ideally, faucet water that contains fluoride aids to rinse out your mouth and then down the sugar that sticks on the tooth surface.


Practice Excellent Dental Hygiene

Good dental health involves more than just brushing. It takes a lifetime of careful planning to achieve healthy teeth. It's crucial to take proper steps every day to care for your oral health and prevent problems. This is irrespective of the fact that you've been told that you have nice teeth. All of this involves getting the right oral care products and being mindful of your daily habits.

  1. Brush twice a day

  2. Consider using a fluoride toothpaste

  3. Treat flossing as important as brushing

  4. Say no to tobacco consumption

  5. Ensure to visit your dentist at least twice a year

In Short:

Besides seeing your sugar intake, attempt to consume a healthy, balanced diet plan, take good treatment of your teeth as well as visit your dental professional consistently to stop tooth decay.



Whenever you eat or drink anything sugary and acidic, you help the germs inside your mouth by simplifying their job. The acid generated destroys the tooth enamel, which causes the dental cavity over time.

To eliminate this, keep your consumption of high-sugar foods and beverages to a minimum- especially in between meals and right before going to bed. Taking excellent treatment of your teeth and exercising a healthy lifestyle are the best ways to win the fight against tooth decay.
