Results and guarantee
How long will the whitening result last?
Keep your results going with a 10-minute top-up every 2 weeks. How long your shade lasts depends on your diet and daily oral care.
What types of stains do your products remove?
Our whitening kit and products work on stains for adults aged 18 and over.
There are three causes of tooth discolouration our products can help with. The first, and the easiest to remove, are surface stains. These are typically caused by tobacco, or by regularly drinking coffee, tea, wine or other coloured drinks such as cola.
Stains can also work through the exterior of the tooth and build up inside the enamel. Excessive fluoride use has been associated with this type of staining, particularly in children. It is trickier to remove, but it can be done with our Advanced Teeth Whitening Kit.
The third type is age related, and is usually a combination of surface stains and staining inside the enamel. This can be removed too, although how much depends on the thickness of your enamel. As we age, the core tissue of the tooth, the dentine, naturally yellows, and the enamel covering it thins through abrasion, letting more of the dentine show through. The thinner the enamel, the more stained the teeth appear.
For the best result we recommend using our Advanced Teeth Whitening Kit together with our Whitening Toothpaste.

This doesn’t affect your rights if a product is faulty. For full details, see our terms and conditions.
Do your teeth whitening products work on crooked teeth?
Yes, our products work on crooked teeth. The mouth tray is a universal, non-moulding tray designed to fit our whitening LED light, and it cannot be modified. Its job is to stop your lips and saliva from wiping the gel off your teeth.
Once the tray is in, press it gently against the front of your teeth and then let go. The gel stays on the tooth surface even where the tray is not in direct contact. You can also use our Whitening Pen to apply the gel directly to your teeth first, then insert the tray and light as normal.
Using the products
How long do I have to use the teeth whitening kit to achieve the best results?
Most customers see a noticeable difference in the colour of their teeth after the first 10-minute application. For the full result (up to 8 shades whiter), whiten for 10 minutes a day for 7 days in a row. For best results, you can run up to three 10-minute cycles in one session.
Do your teeth whitening products work on veneers/caps/crowns?
Our products are safe to use on veneers, caps and crowns, and can remove surface stains that have built up on them over time. Keep in mind that they cannot make dental work whiter than its original colour.
Who is teeth whitening suitable for?
Teeth whitening is suitable for adults with healthy teeth and gums and no active dental issues such as cavities, gum disease, cracked teeth, or exposed roots. A healthy mouth helps reduce the risk of sensitivity or irritation and ensures whitening treatments are safe, comfortable, and effective.
Why is teeth whitening recommended only for people over 18?
We don’t recommend whitening for anyone under 18, as teeth are still developing.
Can I brush and floss my teeth as normal when using your teeth whitening products?
Yes, you can brush and floss as normal while using our products.
We only recommend using a toothpaste without fluoride just before a treatment, because fluoride can leave a thin layer on the teeth that reduces the whitening result.
Our natural Whitening Toothpaste is fluoride-free, and is a good way to keep your smile bright between treatments.
You can also simply brush with water to clear any food from the surface of your teeth before each treatment.
Do not brush straight after a whitening treatment, as this can cause temporary sensitivity to hot and cold foods.
How does your mouth tray work?
Our mouth tray is a universal, non-moulding tray designed to fit our whitening LED light. It stops your lips and saliva from wiping the gel off your teeth, and it covers the top and bottom teeth together so the whole smile is treated at once.
How does the teeth whitening process work?
The active ingredient in our whitening formula penetrates the enamel to reach and break down the discoloured molecules on your teeth.
Our blue LED accelerator light activates the formula and speeds up the process, helping it lift stains.
Can I use your teeth whitening products while I'm pregnant or breastfeeding?
Unfortunately, we do not recommend using our products while pregnant or breastfeeding.
Can I use your teeth whitening products if I have a fixed retainer on the back side of my teeth?
Yes. A bonded retainer will not cause a problem, because whitening is done on the front of the tooth and does not affect the retainer or the glue holding it.
Can I use your teeth whitening products if I have braces?
We recommend waiting until your braces have been removed before starting your teeth whitening treatments for best whitening result.
Can your teeth whitening products be used on amalgam fillings?
We do not recommend using our products if you have amalgam fillings, as excess gel can reach them. If you have any questions or concerns about your dental work, please speak to a dental practitioner about the options available to you.

Is teeth whitening with SmilePro safe?
Yes. Our products are safe when used as directed. The gel is enamel-safe and formulated to prevent sensitivity in healthy teeth and gums.
Do your teeth whitening products cause sensitivity?
Our products are formulated to prevent sensitivity in healthy teeth and gums. If you already have sensitive teeth, check with a dental professional before you start, as there may be an underlying cause.
In healthy teeth, enamel protects the softer layer of dentine underneath, and the gums protect the roots. If the enamel wears down or the gum line recedes, the dentine is exposed, which is what triggers pain in sensitive teeth.
