How do peroxide-coated strips work on the front teeth?
Whitening strips are flexible materials coated with a peroxide gel that contacts the front surfaces of teeth. The amount and frequency depend on the product formulation, fit, contact time, and whether your teeth and gums are healthy.
How can you use whitening strips according to their label?
Read the complete label and use the stated schedule rather than adding strips during the day. Keep gel off the gums, do not sleep in strips unless the product specifically directs it, and pause if sensitivity or gum irritation develops.
When should dental problems be assessed before whitening?
Arrange dental assessment before whitening if you have cavities, cracked teeth, untreated gum disease, exposed roots, or severe sensitivity. Seek advice for persistent pain, chemical irritation, or uneven colour.
What should you ask about whitening schedules and restorations?
Ask which product and schedule suit your teeth, whether existing fillings or crowns will change colour, and how to manage sensitivity without overusing the strips.
Frequently asked questions
Can I use two strips at once?
Do not exceed the product directions. More gel or longer contact can irritate soft tissues and increase sensitivity without giving a predictable result.
Why are my teeth still uneven?
Whitening affects natural tooth structure and may reveal differences caused by restorations, enamel wear, or deeper discolouration.
