Smile time teeth whitening
Smile Time whitening refers to professional tooth bleaching that lightens natural enamel after an examination of your teeth and gums.
The short answer
Smile Time whitening is professional bleaching of natural tooth enamel, planned after checking your teeth, gums, fillings, and existing restorations.
How does peroxide gel break down tooth discolouration?
The whitening gel contains a peroxide compound that breaks down colored molecules within enamel and dentine. It changes the shade of natural teeth, but it does not bleach crowns, veneers, fillings, or bonding.
What needs checking before you start whitening?
A dentist examines for decay, cracked enamel, gum inflammation, and exposed root surfaces before selecting an in-clinic or supervised home method. Follow the prescribed contact time, keep gel off the gums, and reduce strongly colored foods and drinks while whitening.
When should you arrange an examination before whitening?
Arrange an examination before whitening if you have tooth pain, untreated cavities, bleeding gums, enamel defects, or marked sensitivity. Stop the product and contact the dental team if burning gum pain, persistent sensitivity, or swelling develops.
Which whitening strength and schedule may suit you?
Ask which stains are likely to respond, whether any fillings or crowns will need color matching, and which peroxide strength and wear schedule fit your teeth. Ask how sensitivity will be managed and when replacement restorations should be considered.
Frequently asked questions
Will whitening remove every stain?
It can respond to many surface and internal stains, but some medication-related, developmental, or restoration-related color needs another approach.
Can whitening cause sensitivity?
Temporary sensitivity can occur, especially when enamel is thin or dentine is exposed; the dentist can adjust the product or schedule.
