Crest 3D Whitestrips are an easy and convenient way to whiten your teeth at home without the need for whitening trays.
Follow these simple steps to get the most from your whitening treatment.
1. Prepare Your Teeth
Make sure your teeth are clean and free from food debris before applying your whitening strips.
Avoid brushing your teeth immediately before applying the strips, as this may increase gum irritation.
2. Open the Whitening Strips
Carefully open one sachet of Crest 3D Whitestrips.
Inside, you will find two whitening strips:
- Longer strip: For your upper teeth.
- Shorter strip: For your lower teeth.
Carefully peel each strip away from its plastic backing.
3. Apply the Whitening Strips
Position the gel-coated side of the strip against the front surface of your teeth.
Align the straight edge of the strip close to your gumline, avoiding direct contact with your gums.
Gently press the strip against your teeth to ensure good contact.
Fold any remaining strip behind your teeth to help hold it securely in place.
Repeat the process for your lower teeth.
4. How Long Should I Leave Crest Whitestrips On?
The recommended treatment time depends on which Crest 3D Whitestrips product you are using.
Most varieties are designed to be worn for approximately 30–60 minutes per treatment, although some products have different instructions.
Always follow the treatment time printed on your specific Crest Whitestrips packaging.
Do not leave the strips on for longer than recommended.
5. Remove the Whitening Strips
Once your treatment time is complete:
- Gently peel the whitening strips away from your teeth.
- Dispose of the used strips in the bin.
- Rinse your mouth with water to remove any remaining whitening gel.
- Alternatively, gently brush away any remaining gel.
Do not reuse whitening strips.
6. Repeat Your Treatment
For best results, use your Crest 3D Whitestrips according to the recommended treatment schedule on your packaging.
Different Crest Whitestrips products have different treatment courses, typically lasting between 10 and 20 days.
Do not apply extra strips or increase your treatment time to speed up whitening.
Helpful Tips
Avoid brushing immediately before whitening. This can help minimise gum irritation.
Apply strips to dry teeth. Gently drying your teeth before application may help the strips adhere more securely.
Avoid eating or smoking while whitening. Do not eat or smoke while wearing your whitening strips.
Avoid staining foods and drinks. Limiting coffee, tea, red wine and other strongly coloured foods and drinks during your whitening course may help maintain your results.
Use only as directed. Applying more strips than recommended will not necessarily improve your results and may increase sensitivity.
Tooth Sensitivity
Some people may experience temporary tooth sensitivity or mild gum irritation when using Crest 3D Whitestrips.
If sensitivity occurs, take a break from whitening and follow the sensitivity advice provided with your product.
If sensitivity or irritation becomes significant or persistent, stop using the product and speak to your dentist.
Important Information
- Crest 3D Whitestrips are intended for natural teeth.
- Whitening strips will not change the colour of crowns, veneers, fillings or other dental restorations.
- Do not use on damaged teeth or irritated gums without consulting your dentist.
- Do not swallow the whitening gel or strips.
- Keep out of reach of children.
- Follow the manufacturer’s instructions for the specific product you are using.
Remember: Always check the recommended application time and treatment duration on your Crest Whitestrips packaging before starting.
Additional instructions for Crest LED whitening kits
If your Crest Whitestrips kit includes an LED whitening light, apply and wear the strips for the full recommended treatment time first. Then use the LED light according to the instructions supplied with your particular kit. Some Crest kits specify approximately five minutes of LED use.
For your website, I recommend keeping this as one universal guide rather than giving every Crest product the same treatment duration. Crest’s official instructions confirm that application times vary by product, including 30-minute and 60-minute treatments.
