Frequently Asked Questions

 

GENERAL QUESTIONS

Q. How does the Spa Dent teeth whitening system work?

Our revolutionary gel formulation is placed in our dual arch mouth trays with the precise dosage of whitening material. Our unique blue and red LED teeth whitening light, provides powerful whitening with cellular stimulation. Hydroxyl radicals penetrate the tooth enamel to break down stains into progressively smaller particles. This process will penetrate but not harm or damage the tooth enamel, including caps, crowns and veneers. This whitens the whole "smile" area of a patient’s teeth.

Q. Do I need to have my teeth cleaned prior to whitening?

We recommend that you have your teeth cleaned prior to whitening if you have not had them cleaned in the previous 3 months. For maximum results whiten at your cleaning session. Some Dental Professionals also offer a quick clean service. If you have not had your teeth cleaned in the previous 3 months you will need at least a polish prior to whitening.

Q. Why do you have two different whitening kits?

Two different sessions were developed in order to provide patients with flexibility in time for your whitening needs. Our in office 20 minute procedure takes about 30-40min in total including preparation time. Our new take home kit provides you with a tray, an intraoral light and whitening gel to administer the product yourself if you feel comfortable to do so in the comfort of your own home.

Q. How many sessions do I need?

For initial whitening one 20 minute extra strength session is recommended. Your dental professional will determine your exact whitening requirements. A small percentage of patients with severe staining may require an additional session.These can usually be done back to back the same day in less than one hour.

Q. Is whitening safe for tooth enamel?

A review of available studies indicates no evidence of harm to enamel based on our whitening protocol and gel formulation. Problems with enamel are typically associated with highly acidic products notably sodas and a variety of fruits. Our gel is virtually PH neutral as it is balanced to a 6.5PH level and has Xylitol which increases saliva production helping to mineralize teeth.

Q. Will my teeth be sensitive?

Over 98% of people have no tooth sensitivity. Should you experience pain during your session and need to stop the treatment, there is no charge for the product.

Q. What if I have Caps, Crowns, or Veneers?

All of these stain over time through normal eating and drinking. Our process will not harm any of these and will remove the stains that have accumulated over time returning them to their original colour.

Q. How long will it last?

Typical results vary based on a number of factors including genetics and lifestyle. While no two people are the same most people will want a single touch up session every 3 to 9 months. Depending on how often you whiten most people will only need one session to return to their whitest shade.

Q. What results can I expect?

A number of factors determine results including genetics and your starting shade. Almost all individuals depending on starting shade will see 2 to 8 shades after 2 extra strength sessions.

Q. How often can I use your product?

The majority of people will need 2 initial extra strength sessions after which only a single touch up session is required. We suggest that your dental professional provide a complimentary shade guide reading as part of your Dental appointment. Touch up sessions are normally booked after the time of your next cleaning.

Q. How long before I can eat or drink after my treatment?

For the first 24 hours we recommend avoiding coffee, tea, cola, red wine, berries, or any foods that have the propensity to stain. Avoid consuming food and drink other than water for at least 1 hour after your session.

Q. What causes stains?

Some teeth are naturally pigmented or stained as they develop. Typically, stains come from exposure to tea, coffee, smoking, juices, colas, red wine etc.

Q. What if my teeth are heavily stained?

Most people will achieve their whitest possible shade after 2 extra strength sessions. In some cases for extremely stained teeth it can take an additional session. Your dental professional will guide you for what will work given your particular circumstances.

Q. What if my teeth are stained from medications such as tetracycline?

A number of medications can stain teeth. In many cases these are stains that can at least be partially removed. Depending on the stain your teeth may not whiten. Your dental professional will review your specific case.

Q. Can I use your products if I have cavities, I am on medication, or have gum disease?

Research has shown that if teeth and gums are normal and healthy there are no adverse effects from teeth whitening. It is important that if you have any oral problems you consult your dental professional. People with tooth decay and with any type of gum disease should avoid teeth whitening products. People that are photosensitive or taking photosensitive medication should consult their dental professional. People with sensitive teeth or with skin sensitivity should space the treatments at least 4 hours between sessions.

Q. Who may benefit from teeth whitening?

Almost everyone can enjoy the benefit of the whitening process if their teeth and gums are healthy. Teeth cannot be whitened beyond your specific genetic traits. Most people state they feel better and believe they look healthier after teeth whitening.

Q. Are there any side effects?

Some people may feel a slight tingling sensation, white gum line, or slight tooth sensitivity. These side effects are normally transient. Typically, they will last less than 10 minutes.

Q. Do you recommend I wear the protective eyewear?

Patients must wear protective eye-wear for precautionary purposes as the teeth whitening light is very bright and could cause temporary blurring of vision if looked at directly for several minutes.

 

QUESTIONS ABOUT THE INGREDIENTS

Q. What is the strength of the active ingredient?

Carbamide Peroxide (35%) and the gel is buffered to a near PH neutral level of 6.5. Our extra strength gel adds a Hydrogen Peroxide booster.

Q. Why do you use Carbamide Peroxide?

It is used to whiten teeth, relieve minor inflammation of gums, oral mucosal surfaces and lips including canker sores and dental irritation. The active ingredient is hydrogen peroxide, which acts to oxidise interprismatic extrinsic staining within tooth enamel. Carbamide Peroxide provides a stable slower release than Hydrogen Peroxide ensuring maximum whitening power for the entire time of the session.

Q. Why do you use Carbamide Peroxide and Hydrogen Peroxide in you extra strength gel?

By combining the fast acting Hydrogen Perxoide with a stronger version of our regular gel we are able to dramatically increase results over a 20 minute time frame.

Q. Why does your extra strength kit include a gum barrier?

In order to protect the gums from blanching during the whitening process a quick light cure liquid rubber dam is

applied to the upper and lower gums at the front of the mouth. This ensures an added level of safety when using the extra strength gel.

Q. What are the benefits of Potassium Nitrate?

Potassium Nitrate is used in toothpastes for treating sensitive teeth and it’s use has increased dramatically and is approved as a monographed drug by the FDA. As a significant benefit it also helps whitening as it is also an oxidising agent.

Q. What is Xylitol?

It is a "tooth friendly" sugar. Early studies from Finland in the 1970s found that a group chewing sucrose gum had 2.92 decayed, missing, or filled teeth compared to 1.04 in the group chewing xylitol gums. Xylitol is not only safe for pregnant and nursing women, but studies show that regular use significantly reduces the probability of transmitting the Streptococcus mutans bacteria, which is responsible for tooth decay, from mother to child during the first two years of life by as much as 80%.

Recent research confirms a plaque-reducing effect and suggests that the compound, having some chemical properties similar to sucrose, attracts and then "starves" harmful micro-organisms, allowing the mouth to mineralize damaged teeth with less interruption. Xylitol based products are allowed by the U.S. Food and Drug Administration to make the medical claim that they do not promote dental cavities.

Finally a significant benefit of Xylitol is that it increases salivary flow which helps to mineralize teeth during the whitening process which serves to reduce sensitivity by increasing the ability to deliver potassium nitrate to the affected areas of the tooth.

 

QUESTIONS ABOUT THE LIGHT TECHNOLOGY

Q. Will the temperature of the light harm my teeth?

The spa-dent blue and red LED light is designed with a maximum of 3 Degrees over body temperature and operates at a specific wavelength optimized for teeth whitening and assisting in gum repair.

Q. Can you describe the light technology?

The SD-800 teeth whitening light operates within two narrow band nanometer ranges one in the blue light spectrum and the other in the red light spectrum. Blue light is well documented for activating teeth whitening gel and red light has been shown by NASA to be effective for wound healing.

Q Why do you use blue and red light?

Blue light is used to activate the gel quickly without any heat or ultraviolet light. Red light is used to stimulate cellular regeneration which helps to heal minor mouth irritations.

Q. How does the light work with the gel?

Light and water break down Peroxide resulting in free radicals (Oxygen atoms) which penetrate the enamel. Chromogenic molecules that cause the staining and discolouring of the teeth are dissolved.

Q. Are there any environmental benefits to LED lights?

Our LED teeth whitening lights use up to 80% less energy than other whitening systems and the light can last for up to 50,000 hours of use.
