Make teeth white at home
At-home whitening can lift surface stains, but a dental check helps match the method to your enamel, fillings, and gum health.
Can you safely make your teeth whiter at home?
At-home whitening can lift surface stains, but a dental check helps match the method to your enamel, fillings, and gum health.
What affects how teeth respond to home whitening?
Begin with brushing using fluoride toothpaste and cleaning between teeth. Avoid abrasive powders and acidic home mixtures, and use only a labelled whitening product as directed.
What should you do before whitening your teeth at home?
A dentist can examine enamel, exposed dentin, decay, cracks, and existing restorations before choosing a tray or another method. Stop if the gums burn, the teeth develop marked sensitivity, or gel contacts the soft tissues.
When should tooth discolouration be checked by a dentist?
Arrange an examination for persistent darkening, a single grey tooth, pain, holes, or bleeding gums. A single discoloured tooth can need testing for pulp injury rather than cosmetic whitening.
What should you ask about whitening your teeth safely?
Ask whether the colour is a surface stain or an internal change, whether decay or gum recession must be treated first, and how existing fillings or crowns will look after whitening.
Frequently asked questions
Can brushing alone whiten teeth?
Brushing removes plaque and some surface stain, but it does not bleach the underlying tooth colour.
Why do my teeth hurt after whitening?
Peroxide can temporarily irritate the tooth nerve or exposed dentin; persistent or severe pain needs an examination.
