Pro whitening system
A professional whitening system uses a peroxide gel, controlled application, and dental assessment to lighten natural tooth enamel.
The short answer
A professional tooth-whitening system uses a peroxide-based gel under controlled dental supervision to lighten stains on natural teeth.
How do peroxide ingredients break down tooth stains?
The active material is usually hydrogen peroxide or carbamide peroxide, which breaks down stain molecules within enamel and dentin. The dentist first checks for decay, cracked teeth, gum inflammation, exposed roots, and restorations that may affect the result.
What should you do before using a whitening system?
Have the teeth examined and professionally cleaned before whitening, then follow the supplied gel amount and wear time if trays are prescribed. Reduce strongly colored foods and drinks during the treatment period, and report marked sensitivity or gum irritation instead of applying extra gel.
When should a discoloured tooth be assessed first?
Seek an assessment before whitening if a tooth hurts, has a visible cavity, or has a gray single-tooth discoloration. Contact the dental team if gel burns the gum, sensitivity persists, or existing restorations no longer match the natural teeth.
Which whitening method and peroxide suit your teeth?
Ask which peroxide formulation and delivery method fit your enamel and restorations. Ask whether a cleaning, filling, root-canal treatment, or replacement of visible restorations should come before whitening.
Frequently asked questions
Does professional whitening remove every type of stain?
It can lighten many surface and internal stains, but some medication-related, developmental, or restoration-related discolorations need another approach.
Can I whiten a crown with a professional system?
No. Whitening changes natural tooth structure, so a crown may need replacement or color planning if it no longer matches.
