White spots on teeth
Chalky patches with several different causes — and several different fixes.
Overview
White spots on enamel have a few common causes, and telling them apart matters because the treatments differ. Patches that appeared after braces usually mark early decalcification around where the brackets sat. Spots present since childhood on several teeth are often mild fluorosis or a developmental patch (hypomineralisation). A new chalky spot near the gumline can be the first stage of decay.
The good news: most white spots can be improved. Options range from remineralising treatment and microabrasion (polishing away the outermost layer), to resin infiltration that blends the patch into the surrounding enamel, to a small bonded filling or veneer for larger patches. Whitening the surrounding tooth sometimes makes spots less obvious too — though it can make them look brighter at first.
The right choice depends on how deep the patch goes, which is something we can assess in the chair.
What to know
- Different causes need different treatments — diagnosis first
- Post-braces spots are early decay scars and can progress without care
- Developmental spots and mild fluorosis are stable and cosmetic
- Resin infiltration can blend many spots invisibly without drilling
- Whitening can help camouflage spots — but may highlight them briefly first
