Question

When enamel is remineralized with fluoride

a. It is a different color
b. The fluoride contains a poison that kills all bacteria associated with dental caries
c. All of the calcium is replaced
d. The resultant remineralized crystal is more resistant to acids

Answer 1

The required "option is d)".

Step-by-step explanation:

• Remineralization of enamel is a natural process and is of the same color.
• The saliva contains calcium, phosphate, and fluoride which helps in the neutralisation of acids present in food.
• Remineralization helps in improving the strength and functioning of the tooth by replacing calcium ions and flouride ions which were removed by demineralization.
• It helps in prevention of cavity formation in teeth and strengthens the teeth by replacing loss of calcium ions, phosphate ions, and fluoride by fluorapatite crystals that are more resistant to acids.
• Hence, the remineralized crystal is more resistant to acids.
