Teeth whitening: methods and safety
Clinic whitening versus home remedies, and when whitening is not a good idea.
How whitening works
Medical whitening agents penetrate enamel and break down internal stains. Results are faster and safer under supervision, after a professional cleaning first.
Beware home remedies
Lemon, charcoal and random amounts of baking soda can dissolve enamel and cause lasting sensitivity. The cheap option here can become the most expensive to fix.
When we advise against it
Untreated decay, active gum inflammation, or severe sensitivity. An examination first determines what suits your case.
