Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
Yes, many studies have proven that teeth whitening is safe and does not cause damage to the enamel. The whitening systems are specifically designed to maintain teeth and gum health, while protecting your enamel & effectively whitening your smile.
Teeth whitening procedures only whitens natural teeth. It will not whiten caps, crowns, veneers, fillings or dentures. Do not use with dental braces. If you are in need of dental work, have dental work or have staining from medication, ask your dentist to determine if whitening is appropriate.
No, I’m afraid no teeth whitening is permanent. The length of time your teeth will stay whiter is influenced by several factors, including how often you drink coffee, tea, dark colas, red wine or smoke. The average length of time whitening lasts is between 6 months and 2 years.
We would advise that our range of natural teeth whitening products would be best for you as because they don’t contain peroxide. This therefore means that they cause no sensitivity at all. You can try the Crest Whitestrips if you like but just start off first using them every few days and build them up. If you do experience sensitivity from the Crest Whitestrips please be aware this discomfort is only temporary and does not require medical attention.
Crest Teeth Whitening
It is best if you do not brush your teeth immediately before applying strips. Open the pouch and remove the strip. Peel the strips from the backing liner and align with gum line. Press gently for good contact. Fold the rest of strip behind teeth to keep in place. Wear strips for required amount of time, then remove and discard.
Noticeable results vary by person, but most people start seeing results after a few days, with full results upon completion of the full pack.
While there is no evidence that teeth whitening while breastfeeding or being pregnant is harmful, we recommend you check with your doctor before using Crest 3D White Whitestrips.
We recommend following usage instructions for each product. Longer wear time can result in tooth sensitivity and/or gum discomfort.
No, Using a strip over again will not provide any tooth whitening benefits. Even though there may be gel remaining on the strip when you take it off, most of the hydrogen peroxide has been depleted.
You can skip or miss a couple of applications without affecting your whitening benefit.
Yes. With Crest 3D White Whitestrips, you can use one strip right after the other (back-to-back). Wear strips for the time instructed, then remove; rinse or wipe if needed, then apply a second strip.
Look into a mirror to properly apply the strips, making sure the strip is in good contact with the teeth. If the strips begin to slip, close your mouth and create suction to tighten the strips up again. Don’t touch the strips excessively with your tongue. You can try gently tucking the strip in the spaces between your teeth with your fingernail, then folding it behind your teeth. Crest Professional Effects have Advanced Seal technology—specially designed to strongly adhere to your teeth.
No, do not wear Whitestrips overnight or while sleeping. These treatments are designed to be worn for the recommended usage time only and can become a choking hazard if worn during sleep.
Yes, the white spots are temporary. These spots are not harmful and will go away in a few hours.
Since the left over gel is not harmful, you can do any of the following:
- Rinse your mouth with water
- Wipe the gel off your teeth
- Brush it off
- Leave it, as it will dissolve eventually.
Eating after whitestrips will not affect results. There are no eating or drinking restrictions after using Crest 3D White Whitestrips.
You can brush your teeth gently after using Crest Whitestrips but DO NOT BRUSH IMMEDIATELY BEFORE TREATMENT. This is to prevent any gum irritation from occurring. We recommend using Crest 3D White Brilliance Whitening toothpaste in conjunction with your strips for optimum results.
Although Crest 3D White Whitestrips that have passed expiration date are still safe, we don’t recommend using them past their expiration date, as the whitening ingredient’s efficacy will be weakened.
