Dental bleaching procedure
Dental bleaching lightens natural tooth colour by placing a peroxide gel on the tooth surface under controlled conditions.
How does a dental bleaching procedure lighten teeth?
Dental bleaching lightens natural tooth colour by placing a peroxide gel on the tooth surface under controlled conditions.
Which active ingredients are used during bleaching?
The active materials are usually hydrogen peroxide or carbamide peroxide, which break down stain molecules within enamel and dentin. Restorations do not bleach, so their colour is assessed first.
What happens during a dental bleaching appointment?
The dentist examines teeth and gums, treats active disease, records shade, protects soft tissues, and applies timed gel cycles. Custom trays deliver measured gel at home as instructed.
When should dental problems be checked before bleaching?
Ask for an examination before bleaching if you have cavities, inflammation, leaking restorations, recession, or strong sensitivity. Stop for severe pain or chemical irritation.
Which bleaching option may suit your teeth and stains?
Ask which stains can respond, whether restorations will match afterward, and whether in-office treatment, custom trays, or another option fits.
Frequently asked questions
Can home care replace an examination?
Home care may reduce irritation or discomfort, but it cannot diagnose or repair a dental cause.
What should make this urgent?
Rapid swelling, fever, uncontrolled bleeding, or difficulty breathing or swallowing needs prompt care.
