Best professional teeth whitening uk
The best professional whitening method depends on your stains, enamel, fillings, and the examination and products used.
The short answer
Professional teeth whitening is chosen after checking the cause of discolouration, tooth health, existing restorations, and the whitening system used. A dental professional may use peroxide gel in the clinic, supervised home trays, or a combination.
What can cause natural teeth to become darker?
Tooth colour can darken from coffee, tea, tobacco, ageing, trauma, or changes inside enamel and dentine. Whitening changes natural tooth colour through peroxide oxidation, but fillings, crowns, veneers, and implants do not whiten.
What should you do before choosing whitening?
Have an examination before choosing a product or clinic. The dentist checks cavities, cracked teeth, gum inflammation, exposed root surfaces, and restorations, then selects gel strength, tray fit, treatment time, and follow-up according to those findings.
When should gum or tooth problems be treated first?
Seek dental care before whitening if you have toothache, bleeding or swollen gums, untreated decay, or marked sensitivity. Stop and contact the provider if treatment causes persistent pain, gum whitening or burning, or sensitivity that does not settle.
What should you ask about whitening and sensitivity?
Ask what caused the colour change, whether any restorations will need replacement for shade matching, which peroxide product and concentration will be used, and how sensitivity will be managed. Ask how the result will be maintained without overusing whitening gel.
Frequently asked questions
Is clinic whitening better than home trays?
Clinic treatment is faster to deliver, while custom trays allow controlled use at home; suitability depends on your teeth and treatment goals.
Will whitening remove a crown stain?
No. Whitening affects natural tooth structure, so a visible crown may need shade planning or replacement after natural teeth are treated.
