Are cavities definitely caused by eating sugar?
Many people have had this experience in childhood: whenever it's time to eat candy, adults would always say, 'Eat less candy, or you'll get cavities.' If someone has cavities, it's always attributed to eating candy. However, adults don't have the same fondness for candy as children do, yet they can still develop cavities. Therefore, cavities are not necessarily caused by eating candy; there are multiple factors that contribute to their formation. Now let's take a look at what causes cavities. 1: Poor oral hygiene It's important to brush your teeth for at least three minutes each time, ensuring that every surface of each tooth is cleaned. It's recommended to brush three times a day (after meals). If oral hygiene is not maintained, food residues can remain, leading to bacterial growth. Once bacteria proliferate, they can gradually erode the teeth, resulting in cavities. 2: Cavity-causing foods Sugar (especially sucrose and refined carbohydrates) These food residues cling tightly to the tooth surfaces, forming a film from salivary proteins. This film can adhere firmly to the tooth surface due to the anatomical structure and biochemical, biophysical characteristics of the tooth surface, and under suitable temperatures, it can produce acid in the deeper layers of the bacterial plaque over time, attacking the teeth, leading to demineralization, and ultimately destroying organic matter, creating cavities. To cause cavities, four conditions must be present: bacteria, oral environment, host, and time. The more of these conditions that exist and the longer they persist, the higher the likelihood of decay.
Many people have had this experience in childhood: whenever it's time to eat candy, adults always say, 'Eat less candy, or you'll get cavities.' If you have cavities, it must be because of eating candy. However, adults don't like candy as much as children do, yet they can still have cavities.
Therefore, cavities are not necessarily caused by eating candy; there are multiple factors that contribute to the formation of cavities. Now let's take a look at what causes cavities.
1: Poor oral hygiene
Each time you brush your teeth, you should brush for at least three minutes, ensuring that every surface of each tooth is covered. It is recommended to brush three times a day (after meals). If oral hygiene is not maintained, food residues can remain, leading to bacterial growth. Once bacteria proliferate, they can gradually erode the teeth, resulting in cavities.
2: Cavity-causing foods, especially sugars (particularly sucrose and refined carbohydrates)
These food residues cling tightly to the tooth surface, forming a film from salivary proteins. This film can firmly adhere to the tooth surface due to the anatomical structure and biochemical, biophysical characteristics of the tooth surface. Under suitable temperatures and with enough time, acids can be produced in the deeper layers of the bacterial plaque, attacking the teeth, leading to demineralization, and subsequently destroying organic matter, creating cavities.
To cause cavities, four conditions must be present: bacteria, oral environment, host, and time. The more of these conditions that exist and the longer they persist, the higher the likelihood of decay.
