Teeth Whitening

What is teeth whitening?
Teeth whitening is a cosmetic procedure designed to lighten tooth color and remove surface stains using peroxide agents (hydrogen or carbamide) that penetrate the enamel. It’s among the most requested dental treatments, with results ranging from subtle lightening to up to 10 shades whiter. This is not a permanent procedure and requires regular touch-ups for lasting effects.

How does whitening work?
Whitening agents pass through enamel micro-pores, breaking down pigment molecules via free radicals. This chemical process transforms stubborn stains into lighter compounds and may also whiten underlying dentin. Success depends on agent concentration, exposure time, light/heat use, and product pH.

Types of whitening available

• In-clinic professional whitening: hydrogen peroxide 15–43%, immediate results in one session (60–90 min), gum protection, price €300–500
• Dentist-supervised home whitening: custom trays with carbamide peroxide 10–22%, daily application for 2–4 weeks; price €150–400
• Over-the-counter products: strips, gels, toothpaste, lower concentration, gradual results; price €20–100

Is teeth whitening safe?
Always get a professional assessment first. Supervised procedures minimize risks and maximize results; several agents are FDA-approved. Not advised for pregnant/nursing women, under 13s, active decay or gum disease. Existing dental work (crowns, veneers) will not whiten.

Side effects and management

• Temporary tooth sensitivity (most common, resolves in 24–48 hours with desensitizing paste)
• Mild gum irritation if gel contacts soft tissues (short-term)
• Uneven results if you have dental restorations or intrinsic stains

Ideal candidates
Healthy teeth with no active cavities, extrinsic stains from food/drink/tobacco, and commitment to post-treatment care. Tetracycline/fluorosis stains, root canal teeth, or severe sensitivity require special assessment.

Results duration and maintenance
Results last 6 months to 2 years, depending on habits (smoking, coffee, oral hygiene). Maintain by avoiding staining foods/drinks for 48 hours, using a straw for dark beverages, and scheduling regular touch-ups.

How to choose your method
Consider budget, available time, sensitivity, stain type, and lifestyle. For events: in-clinic is fastest; for limited budgets: home kits or strips. Sensitive teeth: gradual treatments. Severe stains: consult about veneers.

Pre-treatment steps
Schedule professional evaluation, get a dental cleaning, discuss realistic expectations, follow correct protocols, and keep up with regular checkups.
