1. The short answer
Sometimes after whitening, you might notice temporary white spots on your teeth — but don’t panic.
They’re not damage or permanent marks.
✅ In most cases, white spots are harmless, short-lived, and part of the normal whitening process.
They usually fade within 24–48 hours as your enamel naturally rehydrates.
2. Why whitening can create temporary white spots
Whitening works by using hydrogen peroxide to dissolve deep stains inside enamel pores.
As those pores open and release pigments, the enamel temporarily loses a bit of moisture, creating a chalky white appearance in certain areas.
Think of it like your skin after swimming — pale and dry until it rehydrates.
Once your enamel re-absorbs minerals and moisture from saliva, the shade evens out beautifully.
💡 These spots are temporary — a sign the whitening is working at different depths across the enamel.
3. When white spots are not from whitening
True white spots (called hypocalcification) are caused by fluorosis, enamel defects, or mineral imbalance, not whitening.
Whitening may make these natural spots more visible temporarily because the surrounding enamel lightens — but peroxide doesn’t cause them.
So if you had faint patches before whitening, they might look slightly brighter afterward — but that’s just contrast, not new damage.
