Hismile professional
Professional whitening products use a peroxide or related active gel, and their effects depend on diagnosis, fit, instructions, and tooth condition.
The short answer
A professional HiSmile whitening treatment is a gel-and-tray system whose risks and results depend on its formulation, contact with gums, tooth condition, and clinical supervision.
What is the direct answer?
What does this question mean?
Whitening gel oxidises coloured molecules within natural enamel and dentine. It does not lighten fillings, crowns, veneers, or bonding, and sensitivity or gum irritation can occur when gel concentration, exposure, or tray fit is unsuitable.
What can you do next?
Check the product directions, keep gel on the tooth surfaces rather than the gums, and stop if pain or burning develops. A clinician should examine decay, cracks, gum disease, and existing restorations before treatment.
When should you seek dental care?
Seek care for persistent sensitivity, white or sore gum patches, swelling, uneven colour, or pain in one tooth. An examination is especially important when darkening may reflect decay, trauma, or a dead pulp.
What should you ask the dentist?
Ask which active ingredient and concentration are in the gel, how the tray is fitted, and whether your restorations will match afterward. Ask how to pause treatment and manage sensitivity if it occurs.
Frequently asked questions
Can professional whitening fix a grey tooth?
A grey tooth may have internal discoloration or pulp damage and needs diagnosis before cosmetic whitening.
What if gel touches my gums?
Remove excess gel and stop if burning or soreness develops, then seek advice if symptoms persist.
