How to whiten teeth with enamel loss
Teeth with enamel loss should be examined before whitening because exposed dentine can increase sensitivity and whitening cannot rebuild missing enamel.
The short answer
Whitening may be possible after the cause of enamel loss is assessed, but it will not restore missing enamel and can make exposed dentine feel more sensitive.
What is the direct answer?
What does this question mean?
Enamel is the hard outer layer of a tooth; beneath it lies dentine, which contains microscopic tubules linked to the pulp. Erosion, abrasion, attrition, or acid damage can thin enamel and expose dentine, changing colour and sensitivity.
What can you do next?
A dentist may first treat the cause, smooth sharp edges, recommend fluoride or desensitising care, and restore deeper defects with bonding or another material. Whitening decisions should follow that assessment, with attention to natural teeth and restorations separately.
When should you seek dental care?
Seek care for sensitivity, translucent or chipped edges, grooves, pain, or rapid changes in tooth shape. A dark single tooth, spontaneous pain, or swelling needs examination rather than cosmetic whitening.
What should you ask the dentist?
Ask how much enamel remains, whether dentine is exposed, and which habit or acid source caused the loss. Ask whether bonding, a protective restoration, or supervised whitening is appropriate.
