At home teeth whitening vs dentist

Professional whitening is planned and monitored in a dental clinic, while home whitening uses a product or custom tray outside the clinic.

Both approaches use a peroxide compound to alter stain molecules. Clinic treatment adds examination, gum protection, concentration and exposure control, while a dentist-made home tray delivers gel against selected tooth surfaces over a prescribed schedule.

First have teeth and gums checked, then compare the gel, tray fit, supervision, and aftercare rather than only the headline result. Do not whiten over untreated decay, leaking restorations, or inflamed gums without addressing them.

Seek dental advice for sharp sensitivity, gum burns, uneven colour, or whitening that does not change a dark tooth. A single dark tooth may need assessment for trauma or loss of pulp vitality.

Ask whether the colour is caused by surface stain, internal discolouration, medication, or restoration material, and which option gives the best control for your enamel and gum condition.
