Smile bright whitening
Smile whitening usually means bleaching natural teeth with a peroxide gel after checking for decay, gum disease, sensitivity, and mismatched restorations.
The short answer
External stains can collect on enamel from foods, drinks, tobacco, or plaque, while internal colour comes from dentin, trauma, ageing, medicines, or enamel changes. Cleaning removes deposits, but bleaching changes the colour of natural tooth structure.
What is the direct answer?
What does this question mean?
Have the dentist record your starting shade and examine the teeth before choosing in-office or take-home trays. Follow the prescribed wear time and stop if the gums or teeth become painful.
What can you do next?
Seek care before whitening if you have cavities, leaking fillings, gum bleeding, exposed roots, or unexplained colour change. Report lasting sensitivity, gum burns, or an uneven result after treatment.
When should you seek dental care?
Ask whether cleaning alone will address the stain, which teeth can whiten, and how restorations will look afterward. Ask about gel strength, tray fit, sensitivity control, and maintenance.
Frequently asked questions
Can home care replace a dental examination?
Home care may reduce irritation, but it cannot diagnose or repair an underlying tooth, gum, or mucosal problem.
What determines treatment?
Treatment depends on the affected anatomy, symptoms, examination findings, medical history, and any visible infection or tissue damage.
