Everyone knows that sugar is a challenge for your teeth and your entire intestinal tract, but acidic foods can cause just as many problems. This is because the acid in food and drinks, such as orange juice, temporarily softens the enamel. After you eat, it can take half an hour for the acids in your mouth to neutralize and the enamel to go back to normal. So if you are constantly eating throughout the day, your mouth never has a chance to recover and you will be more susceptible to acid wear and tooth decay. Some foods and drinks are worse for your teeth than others as they have a low pH, meaning that they are very acidic.

What Causes Cavities To Form?

While knowledge of oral hygiene and proper preventive measures has greatly improved since the 1950s, the prominence and availability of candy, pop, and junk food has skyrocketed since then. More than ever, it’s important to learn about the foods and drinks that can harm our teeth and bodies, and learn to promote better eating and oral hygiene habits.

Four ingredients are needed for tooth decay to begin:

  • Destructive Oral bacteria
  • Sugar
  • Acid
  • Time

All four of these ingredients need to be present for tooth decay to begin.

What happens when all these ingredients combine? These type of oral bacteria consume sugar and expel lactic acid into the oral cavity. This lactic acid leaches calcium phosphate crystals from the teeth, causing soft spots (white spot lesions) in the protective enamel coating of the teeth.


This dark drink is a staple in many people’s daily diets, but can be a culprit when it comes to yellowing teeth. To decrease these effects, try drinking less or drinking with a straw to avoid direct contact or follow each cup with continuous water consumption. If you feel that your teeth need a whitening boost, consult your dentist to determine if professional services or over the counter products are the right fit for you.


Similar to coffee, this beverage group also has potential staining power, especially black and other dark tea blends. Again, drinking through a straw and being mindful of the level of consumption will help keep teeth shiny and white.

Energy and Sports Drinks 

This category is probably the worst in terms of sugar levels and acidity, all nightmare ingredients for your teeth. These soda-alternatives can be the most damaging because they attack tooth enamel, which cannot be fixed or replaced. When tooth enamel is worn down, the risk of decay becomes much more serious.


Carbonated soft drinks also possess higher levels of sugar and acidity, which hurt tooth enamel and can lead to decay and cavities. Though sugar free options are better, the acidity is still a major player in dental issues.  Natural drinks are the best for our oral and general health as water and juices.  Juices you should drink maximum only all four hours or less.

Soft Drinks

Going to get a Coke was seen as a special event, and if you’ve ever seen how small those glass bottles were, you’ll know what I’m getting at here. At the beginning of its mainstream popularity, we’d drink a 6.5 ounce soft drink and be thrilled to death with the experience. Now the standard or “average” size soft drink is 24 ounces-over 3 times larger-and we drink them much more often. Yet this is not the upper limit in size.

Soft Drinks contain a lot of sugar or artificial sugar, both is harming our teeth and our body.  Because of a high concentration of sugar, our own mouth flora and the flora (bacteria) in our intestine get strongly damaged.  Our entire immune system gets weaker. Decay appears as a result of the decreased function of the immune system and  the damaged mouth flora.

In case of artificial sugar, you increase the risk for diabetes, because your pancreas produces insulin because of getting the information for “sweet” but no sugar is coming, only artificial sugar.  The pancreas is lowering the amount of producing insulin, because of adapting to this “fake”.  This is one of the reasons to get diabetes.

In general it means that soft drinks can make your life harder.
