Remineralización

Remineralización is a natural process where minerals are redeposited into tooth enamel and dentin. This process is crucial for maintaining healthy teeth and can help reverse early stages of tooth decay. Enamel, the outermost layer of the tooth, is primarily composed of hydroxyapatite, a mineral structure. When teeth are exposed to acids, often from the bacteria in our mouths metabolizing sugars, these minerals can dissolve, a process called demineralization.

Remineralization occurs when minerals, particularly calcium and phosphate ions, are available in the oral environment and can be incorporated back into the weakened enamel structure. Saliva plays a vital role in remineralization by providing these essential minerals and buffering the acids produced by bacteria. Fluoride significantly enhances the remineralization process. It incorporates into the tooth structure, forming fluorapatite, which is more resistant to acid attacks than hydroxyapatite. Fluoride also helps to attract calcium and phosphate ions to the tooth surface, further promoting remineralization.

Factors that support remineralization include good oral hygiene practices, such as regular brushing and flossing, which remove plaque and food debris. A balanced diet, low in sugar and acidic foods and drinks, also contributes to a less acidic oral environment, favoring remineralization. Dental products like fluoride toothpaste and mouthwash are designed to deliver fluoride to aid in this restorative process. Remineralization is key to preventing cavities and maintaining the integrity of tooth structure throughout a person's life.
