Simple white teeth whitening
Simple teeth whitening usually means removing surface stain and, when suitable, using a peroxide gel to lighten natural tooth colour.
The short answer
Brushing removes plaque but cannot bleach enamel. Professional whitening uses hydrogen peroxide or carbamide peroxide, which penetrates tooth structure and changes stain molecules.

What does a dentist check before choosing whitening?
A dentist checks for decay, gum recession, cracks, sensitivity, and restorations before selecting trays or an in-office method. Restorations keep their original shade.
How can you follow a simple whitening routine safely?
Use fluoride toothpaste, clean between teeth, and follow whitening instructions exactly. Avoid abrasive powders and do not leave peroxide on longer than directed.
When should a darker or painful tooth be assessed?
Seek care before whitening if a tooth hurts spontaneously, the gums are sore, or one tooth has become darker. Whitening is not a substitute for treating disease.
What should you ask about stains and colour matching?
Ask whether your discoloration is surface stain or internal, and whether fillings, crowns, or veneers will need colour matching.
Frequently asked questions
Can brushing alone make teeth white?
It can remove plaque and some surface stain, but it does not produce the same chemical lightening as peroxide whitening.
What should I do while arranging an examination?
Use fluoride toothpaste, clean between teeth, and follow whitening instructions exactly. Avoid abrasive powders and do not leave peroxide on longer than directed.
