Frequently Asked Questions

No. Teeth Whitening is considered a cosmetic treatment and not a dental procedure. With our professional client self-administered teeth whitening system you are not entering your clients’ mouth. The prefilled silicone whitening tray is applied by the client, and you simply set the light. You have zero direct contact with your clients mouth.

The teeth whitening process begins with using a patented mouth tray and an LED Whitening Accelerator light. The Whitening Accelerator light produces an intense cold-blue light, illuminates the teeth, and boosts the release of hydroxyl radicals at a wavelength of 400 to 500 nanometers which is proven to be the optimal range for teeth whitening. Harmful ultra-violet (UV) and infrared light is completely removed by the filtering system, leaving only a focused beam of cold blue-light in the blue-cyan spectrum, penetrating deep into the tooth, and activating the whitening formula to its optimal potency. The teeth whitening kit is designed to work specifically with the accelerator light. The pre-filled tray is designed to press the carbamide peroxide gel onto the tooth surface for optimal whitening. The accelerator light produces an intense cold light which activates the gel and rapidly accelerates the whitening process. In just 30 minutes, tooth discoloration from years of staining foods and drinks, coffee and tobacco products are eliminated, leaving beautiful, bright smile.

Eighteen (18) years of age is the minimum age. However, a 16 – or 17 -year-olds can whiten their teeth with the consent of their parent or guardian. Anyone under the age of 16 must have approval from their

The teeth whitening treatment delivers phenomenal results for natural teeth that have been stained by smoking or by substances like coffee, tea, or red wine. It is likely that it may help dental restorations, such as bonds, veneers, fillings, or crowns by getting closer to the original color their dentist first gave them and help even out their smile. However, we do not guarantee this. There has also been success with clients that have discoloration caused by steroids and chemotherapy. It is suggested that they are given a two-session package. Pregnant women, children under the age of 16, and patients with periodontal disease are discouraged from undergoing this procedure. Also, anyone with sores or cuts in their mouths, dental work that needs to be done (fillings, root canals, etc.) or have gum disease are advised to have this corrected by their dentist prior to getting this procedure.

Individual results vary depending on your genetics, what type of stain you have (yellow=easiest to remove, brown=somewhat more difficult to remove, gray=difficult may require a series of treatments), and how thick your enamel is. We typically see 2 – 5 shades improvement in the first session. 

Our pre-filled silicone trays contain 36% or 44% carbamide peroxide that is perfectly balanced and does not damage the tooth enamel. Take Home Whitening Pen 12% hydrogen peroxide.

Individual results vary, depending on your tendency to absorb stains, your diet (coffee, tea, red wine, sodas, etc. and lifestyle (tobacco products).
Results can last up to 2 years, with proper maintenance: using the Whitening Pen, avoiding staining products, avoiding enamel-stripping substances (drugstore white strips, sugar, sodas), avoiding drugstore whitening toothpastes that contain silica or other abrasive ingredients which scratch enamel.

Getting 2-4 sessions per year greatly helps prevent relapse. We recommend clients use the whitening pen for maintenance, to remove daily stains but not for tougher, deeper stains from years of accumulation.

SiS Smiles specially formulated gel products are manufactured in a lab in the USA. FDA and ADA approved.

Yes. This is an FDA-approved product. Our product does not cause sensitivity; we do not use citric acid, silica, or any other damaging agent to the enamel in our product. When teeth are normal and healthy there are no adverse side effects on the tooth’s enamel.

If your client does not show any adverse reactions and they wish to have an additional 30-minute treatment place additional gel using the syringe to refill they tray. Do not over fill outside the indicated fill line in the tray.  You can then start the light again for 30-minutes. This can be done on clients who may have darker stains.


We recommend 2-4 treatments per year to prevent relapse and increase your overall shade. Relapse is when your tooth color reverts to its original color. Not everyone will relapse, and it is hard to know who will relapse and who will not. It depends on genetics, but we find that relapse is rare after 3 sessions and use of the take home whitening pen nightly to maintain a bright smile. The average client will return once every 6-12 months for a follow-up, but results can last up to 2 years.

Teeth Whitening is not effective on individuals with stained teeth because of certain medications, decalcification, or those who were born with grayish or brown teeth. It is not recommended for pregnant or nursing women, or children under 18 unless written permission from an adult.


No. However, it can brighten up old dental work that have accumulated stains over the years. We cannot whiten any dental work beyond the original color that the dentist put in, but we may be able to  restore it to its original color. The process does not adversely affect these structures or fillings.

You may experience some tingling however, most of our customers experience no pain or sensitivity after the treatment.

SiS Smiles gel  was engineered to be an effective, affordable and a pain free treatment.
