Frequently asked questions


To understand how teeth whitening works, first you need to understand how your teeth became stained. Tooth enamel contains millions of microscopic pores and through natural expansion and contraction the pores becomes embedded with unprocessed compounds from food, drink and tobacco causing tooth discolouration and staining. No amount of brushing your teeth will remove these stains as they are embedded within the enamel layer. Think of your enamel layer as a glass window that is encased around the white bone of your tooth called ‘Dentin’. When the enamel layer or glass is stained it veils the natural white colour of your Dentin and your teeth appear yellow or darker than they naturally are. Enamel is the window through which we see the underlying layer white Dentin. Dentin is the actual ‘tooth-bone’ that gives your teeth their natural white colour. Teeth Whitening happens when a special oxygen-action whitening gel is applied to the front of the teeth; combined with the aid of the Advanced Teeth Whitening Accelerator Light the gel migrates throughout the minuscule pores of the enamel, oxidising stains and leaving behind only the natural colour of the white Dentin.


The Beamingwhite whitening system is the most developed, safest and gentle system available on the market today. Prior to your treatment a full examination and consultation will be carried out to check it is safe to perform the procedure. If you do suffer from tooth and gum sensitivity or you are allergic to peroxide (the whitening ingredient), then sensitivity is more likely to occur. For these people we recommend you stay away from extremely hot and cold drinks or desserts for 24 hours ‘pre and post’ treatment and use of Sensodyne toothpaste for 1 week before and after your teeth whitening treatment. As for the damage to tooth enamel it’s considered as the hardest part of the human body and research has shown that bleaching your teeth with low concentrations of peroxide, from a reputable source by a trained Teeth Whitening Practitioner is safe and will not harm the enamel of the teeth. In a recent study it was found that drinking a glass of orange juice is more detrimental to tooth enamel than a teeth whitening treatment.


Teeth Whitening happens when a special whitening gel is applied to the face of the teeth combined with the aid of a Teeth Whitening Accelerator Light the gel migrates throughout the millions of tiny minuscule pores of the enamel oxidising the stains. It is important to understand the gel is most effective in the first 15 to 20 minutes (see diagram) the more cycles you have the deeper the gel migrates into the enamel layer giving whiter results. For example a two cycle treatment is considered a light whitening or refresh option best for those who’s teeth are prone to re-staining requiring regular treatments every 3-6 months. Our most popular treatment is the RADIANTwhite a three cycle teeth whitening treatment best suited for average staining, or for those who’s teeth are look a little yellower than they would like. For people with dark stains especially in between teeth on the bottom row they would require the ULTIMATEwhite four cycle treatment. BEWARE of companies offering a Single 30-minute Cycle. It may save THEM time and expense on whitening gels, however, because the gel is most effective in the first 15 to 20 minutes the remainder of treatment time is ineffective and your teeth WILL NOT be as white as they could have been. Another one to look out for are companies offering deals with for Two 20-minute Cycles who give no indication as to what level of discolouration this treatment is best suited. This is great treatment if you’re only wanting a ‘refresh or light whitening option’ but again you won’t get results if you’re a first timer to teeth whitening with average staining. Here at The Smile Spa we are transparent with our pricing and describe in full the treatment options including the ‘number of cycle’s and ‘amount of time’ you will spend under the light accelerator in the ACTIVE WHITENING PROCESS. Our system is scientifically proven to whiten better than EVERY other whitening system available on the market today including LASER and LED.


Up to one year is possible but depends greatly on your lifestyle, diet and habits. However, for most in-clinic teeth whitening treatments last between 6 – 9 months. If you drink a lot of coffee, tea, dark soda, red wine or smoke cigarettes, the results will obviously not last as long and you may have to repeat the process more often. We recommend the use of a Smile Spa teeth whitening pen and/or whitening foam to prolong the results of your treatment and to maintain your white smile.


Almost anyone can benefit from having their teeth whitened at The Smile Spa. The people who get the best results include: Tea and coffee drinkers, tobacco users, and those with stains acquired by dietary habits. These stains appear more yellow sometimes yellow/brown and occur on the outermost surface of the tooth, they are easiest to lighten and remove. Those with intrinsic stains (stains that appear greyish, grey-brown or grey-blue) and require more applications. because that the gel must pass through the pores of the enamel and into the dentin.


Everyone’s teeth are different; we all have different body chemistry, dental health, lifestyles, and genetics. After undergoing whitening with iSmile™ most clients teeth can be whitened between 3 – 9 shades lighter. Most extrinsic stains (staining on the exterior of the tooth) caused by food, drink, cigarettes can be removed by the Beyond Polus system bringing your teeth back to their natural white state. Those with intrinsic stains (staining on the interior of the tooth) that rest below the surface of the enamel caused by medications or tooth decay may appear greyish, grey-brown or grey-blue may require two separate sessions (2 days apart) and maintenance treatments every 3-6 months to get the best results.


  • People under the age of 16 years.
  • Women who are pregnant or breastfeeding (no research has been conducted on the use of teeth whitening while pregnant or nursing and is therefore not advised).
  • Anyone allergic to peroxide (the whitening agent).
  • People with gum disease, periodontal disease, oral cancer, worn enamel, cavities, and exposed tooth roots.
  • Individuals with chronic tooth and gum sensitivity, receding gums and/or defective restorations.
If still unsure we recommend you consult with your dentist prior to using any tooth whitening system.

Teeth whitening works on your natural teeth and it won’t damage or affect your crowns, bridges, veneers or any other dental work. If anything we have found with our whitening treatment that surface stains on some artificial teeth may be improved or at least taken back to their original colour when first fitted. You will still need to consider there might be a difference between their colour and improved colour of your natural now whiter teeth. If you have had a lot of work on your mouth but you still wish to brighten your smile, then you probably need to seek advice from a dentist. They can update the crowns, bridges and veneers to match the whiter colour of your natural teeth if you so desire.

It is therefore recommended that only white food and drink are consumed over this period to avoid re-staining as per the food and drink suggestions below: Do not eat or drink dark, staining substances such as: coffee, tea, red wine, soy sauce, and cola. Do not eat staining foods such as: beetroot, carrots, blueberries and the like; try to stick to a “white” diet such as Fish, Chicken, Potatoes and Cauliflower

Although uncommon, some people can experience some tooth sensitivity called “zingers” during the first 24 – 48 hours after the whitening treatment. People with existing sensitivity, recently cracked teeth, micro-cracks, open cavities, leaking fillings, or other dental conditions that cause sensitivity may find that these conditions increase or prolong tooth sensitivity after the treatment. If you experience tooth sensitivity after the treatment, you can use Sensodyne™ toothpaste to ease the discomfort. Brush your teeth with this toothpaste until tooth sensitivity goes away. If you have tooth sensitivity do not begin with your touch-up pen treatment at home. Wait until the sensitivity goes away and then begin with the home treatment.
