Does hismile damage your enamel
A whitening kit’s effect on enamel depends on its ingredients, concentration, contact time, application, and the condition of the teeth.
Can a whitening kit change or damage tooth enamel?
A whitening kit’s effect on enamel depends on its ingredients, concentration, contact time, application, and the condition of the teeth.
How do whitening ingredients affect stains and enamel?
Whitening products use peroxide or other ingredients to alter stain molecules, while enamel itself is not a living tissue that regrows. Irritation and sensitivity can result when product contacts gums, dentine, cracks, or exposed roots.
How can you use whitening gel more safely?
Read the ingredient and use instructions, keep gel off the gums, and do not extend contact time or combine whitening products. A dentist can check decay, erosion, restorations, cracks, and the source of discolouration first.
When should whitening be stopped and checked by a dentist?
Stop and seek dental advice for persistent pain, marked sensitivity, gum burns, uneven colour, or a tooth that changes colour alone. Do not whiten over untreated decay, leaking fillings, or unexplained tooth pain.
What should you ask about enamel before whitening?
Ask which ingredient and concentration the product contains, whether your enamel and gums are suitable, and whether fillings or crowns will change colour. Ask how to manage sensitivity and whether another option fits your staining.
Frequently asked questions
Can whitening cause enamel loss?
The relevant risks depend on the product and use; excessive or inappropriate application can cause irritation and sensitivity, so follow the instructions and seek an assessment.
What if my teeth hurt after whitening?
Pause whitening and contact a dentist if sensitivity persists, is severe, or affects one tooth.
