Is getting your teeth professionally whitened bad
Professional whitening is a controlled peroxide treatment, but it can irritate teeth or gums and should wait until some problems are treated.
Can professional teeth whitening harm your teeth or gums?
Professional whitening is a controlled peroxide treatment, but it can irritate teeth or gums and should wait until some problems are treated.
How does peroxide whitening affect tooth colour?
Peroxide breaks down coloured molecules in enamel and dentine; examination distinguishes stain from decay, cracks, or restorations.
Sensitivity and gum irritation depend on gel exposure, exposed dentine, enamel defects, and gum health.
What should you do before and during professional whitening?
Have decay and gum inflammation assessed, follow the prescribed protocol, and stop for burning or severe pain.
Which whitening symptoms need prompt dental assessment?
Seek care for persistent sensitivity, gum burns, severe pain, or a dark painful tooth.
What should you ask about colour changes and sensitivity?
Ask what causes the colour, whether restorations will change, and how sensitivity is managed.
