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.
What happens when decay begins in the tooth enamel?
Enamel decay is mineral loss from the tooth’s hard outer surface; early lesions may be arrested, while deeper cavities usually need restoration.
Why do plaque acids damage the enamel surface?
Enamel is the mineralised outer layer over dentine, and acids made by plaque bacteria dissolve its minerals.
What can you do now to manage early enamel decay?
Brush with fluoride toothpaste, clean between teeth, and have a dentist assess whether fluoride or a filling is needed.
When should sensitivity or a dark spot be checked?
Seek care for sensitivity, a rough or dark spot, pain, swelling, or fever.
What should you ask about treating an enamel lesion?
Ask whether the lesion is early mineral loss or a cavity and whether an X-ray is needed.
Frequently asked questions
What should I watch for?
