Demineralization is the process where minerals, primarily calcium and phosphate, are removed from the tooth enamel. The demineralization process occurs when acids dissolve essential minerals from teeth.

Healthy oral hygiene practices can prevent demineralization. Regular brushing, flossing, and the use of fluoride toothpaste, help to remove food particles and plaque, reducing the amount of acid-producing bacteria in the mouth. Also, a balanced diet that limits sugary and acidic foods can help maintain a neutral pH level in the mouth, further preventing the onset of demineralization.
