We recommend NOT to eat or drink anything except pure water for at least one hour and preferably two hours after the treatment. Also avoid coffee, tea, colas, red wine, grape juice or other dark liquids or sauces for at least 24 hours and preferably 48 hours.

In theory results can last up to 2 years, but in practice they last less. Depending on a person’s consumption of coffee, tea, red wine, colas and other darkening agents such as tobacco, most people could probably use another whitening session 6 months later. It also depends on the quality of enamel. If someone has non-porous enamel, results will last longer. Those who have porous enamel will be more vulnerable to staining beverages and food. These 2 factors will determine how long results will last. Generally one can say between 6 months (if the customer has porous enamel, drinks staining beverages and/or smokes) and 2 years (if the customer has non-porous enamel and habits that do not include staining beverages and/or smoking).

Tooth sensitivity is extremely rare after a single or double treatment using our gels. Mild tissue (gum) irritation (that tingling or stinging sensation that we mention in the Guide) may occur during the whitening process, but usually only occurs during the procedure and subsides completely shortly after finishing the treatment. Blanching (whitening of the gums) occurs occasionally, but the gums return to their normal color usually within 15 minutes.

After a teeth whitening treatment, it is normal for tooth color to regress somewhat over time. Sometimes, a noticeable amount of color can return over the days following the treatment. The best way to avoid this or limit it is by applying a liquid or gel containing hydrogen peroxide to your teeth over the next 5 days or so. The best product options for this are a touch-up pen or whitening foam with at least 3% hydrogen peroxide, such as Daily White. Certain foods and beverages such as coffee, tea, spaghetti sauce, and red wine speed up color regression. Be aware that lipstick and tobacco also stain teeth. We recommend that you follow The White Diet for at least 24 hours after a whitening treatment. You should also not eat or drink anything other than water over next 60 minutes following the end of your whitening application.

The main side-effect of teeth whitening is winding up with a fabulous, beautiful, white smile. Now, in all seriousness, the following are the typical side effects of an at-home or professional teeth whitening treatment. Please be aware of these before attempting any teeth whitening treatment.

Blanching is when the gums turn white and possibly even sting a little after a teeth whitening treatment, particularly with a professional teeth whitening treatment. Blanching is normal and usually goes away in 5-20 minutes. Rinse your mouth well.

If you experience severe irritation or blistering, stop the treatment immediately. Rinse your mouth with warm salt water and consult your doctor if desired. You may have an allergic reaction or gum disease.

Some people have concentrated amounts of calcium in their enamel, and this usually shows up as white spots or streaks on the teeth. These are most noticeable in children’s teeth, but as people get older and teeth get stained over time, the calcium deposits become not very noticeable. If you have calcium deposits, teeth whitening whitens them more than the rest of the teeth, and they can become quite noticeable. The deposits were always there, so the whitening gel did not create them. That said, over the next couple of weeks, the bright calcium deposits will tone down and will become much less noticeable, so most people don’t think it’s a big deal.

A very small percentage of people experience an allergic reaction that manifests itself as burning and blistering of the gums or lips after using teeth whitening gel. If this occurs, discontinue use immediately, rinse the irritated area well with water, and consult your doctor or dentist if desired. Many people find that an antihistamine helps alleviate the situation.

Peroxide-based teeth whitening gels penetrate tooth enamel to lift stains within dentin layer of the teeth. During a teeth whitening treatment, the enamel loses certain minerals and the enamel can be weakened ever so slightly. We highly recommend that you use a remineralizing gel immediately following a tooth whitening treatment. It is also important to follow instructions for how often it is safe to whiten your teeth, which depends on the type of whitening gel and the strength. Your dentist is best suited to advise you.

Item descriptionWe recommend that you offer your customers a double or triple treatment the first time they get their teeth whitened. After that, we recommend that they get a touch-up treatment every 4-6 moths.

There is a 3 to 1 relationship between carbamide and hydrogen. This means that 16% hydrogen peroxide is equivalent (in theory) to around 44% carbamide peroxide. Some people prefer carbamide because it is softer on the gums. However, in practice we have found that hydrogen peroxide works much faster than carbamide.

Any of the following:

- Pregnant or lactating women
- People with poor enamel or decalcification caused by excessive use of fluorides.
- People with periodontal disease including gingivitis or gums in poor condition
- People who wear braces or who had their braces removed less than 6 months ago
- People who recently had oral surgery
- People with decaying teeth or exposed roots
- People with open cavities
- People with a history of allergic reactions to peroxide products
- People with silver fillings in, near or behind the front teeth
- People under the age of 14

People with such conditions are rare so it can be assumed that over 90% of people can undergo and benefit from teeth whitening.
