Is crest whitening emulsions safe
A whitening emulsion’s risks depend on its peroxide ingredient, concentration, contact time, tray fit, and the condition of your teeth and gums.
The short answer
Whitening emulsions are gels or liquid-gel products intended to contact enamel and release a bleaching ingredient, commonly a peroxide compound.
What is the direct answer?
What does this question mean?
Peroxide can diffuse through enamel and dentine to break down coloured molecules, while contact with gingiva can cause irritation and teeth may become temporarily sensitive.
What can you do next?
Read the ingredient label, follow the supplied contact time, keep the emulsion off the gums, and seek dental advice before use if you have decay, cracks, recession, ulcers, or restorations.
When should you seek dental care?
Stop use and arrange care for persistent sensitivity, painful gum burns, swelling, ulcers, or a change in the surface of a tooth.
What should you ask the dentist?
What peroxide ingredient and concentration are present, and do I have dental conditions that change the risk?
Frequently asked questions
What is the most likely cause?
The cause depends on the location, duration, examination findings, and any dental treatment already done.
Can I manage this at home?
Gentle cleaning and avoiding irritation may help temporarily, but persistent or worsening symptoms need clinical assessment.
