Decay in enamel

Enamel decay is mineral loss from the tooth’s hard outer surface; early lesions may be arrested, while deeper cavities usually need restoration.

Enamel is the mineralised outer layer over dentine, and acids made by plaque bacteria dissolve its minerals.

Brush with fluoride toothpaste, clean between teeth, and have a dentist assess whether fluoride or a filling is needed.

Seek care for sensitivity, a rough or dark spot, pain, swelling, or fever.

Ask whether the lesion is early mineral loss or a cavity and whether an X-ray is needed.
