Paint-on tooth whiteners -
Colgate Simply White Night ® and Crest Night Effects ®
What are paint-on whiteners?
Colgate Simply White Night ® and Crest Night Effects ® are examples of paint-on teeth whitening products. Paint-on teeth whiteners are a relatively new type of whitening system. Colgate introduced their Simply White ® product in 2002. Crest's Night Effects ® and Colgate's Simply White Night ® were brought to the over-the-counter marketplace in 2003.
While the teeth whitening chemistry involved with paint-on teeth whiteners is similar to that of other types of whitening systems, the paint-on delivery technique utilized by these products offers advantages that other whitening systems cannot. This same delivery system, however, also creates some disadvantages for this teeth whitening technique.
The pages of our review describe paint-on whitening products. Both in terms of the science involved and how these products are used.

What is "paint-on" teeth whitening?
For the most part, paint-on teeth whitening / tooth-paint technique is just another whitening method based on the science of peroxide tooth bleaching (the chemical process on which essentially all tooth-whitening products are founded).
What makes paint-on systems different is simply the method by which they (the bleaching agent) are delivered to the surface of the teeth being treated.
It's the delivery system (or really the lack of one) that makes teeth whitening paints unique.
For any type of whitening process to be successful, the bleaching agent must maintain contact with the surface of the teeth being treated. With some whitening methods, this contact is facilitated by the use of bleaching trays or plastic strips.
In the case of paint-on whiteners, no delivery apparatus involved. Instead, the whitener is applied directly onto the surface of the teeth (by way of a brush or applicator). Once applied, the whitener solidifies, thereby creating an adherent treatment film.
What type of peroxide do paint-on teeth whitening products contain?
Colgate's Simply White ® was the first teeth whitening paint brought to the over-the-counter marketplace. And as any dentist might guess, its formulation contains carbamide peroxide (at a concentration of 18%, which is equivalent to 6.3% hydrogen peroxide) as its bleaching agent.
The reason that it might be expected that Colgate would choose this type of peroxide for its Simply White ® product is that carbamide peroxide is the most common peroxide utilized with the dentist dispensed tray-based teeth whitening systems (the whitening technique that ultimately lead to the explosion of over-the-counter teeth whitening products found for sale today).
No doubt Colgate was influenced by the abundance of dental research available from studies and clinical trials detailing the effectiveness and safety of the use of carbamide peroxide as a teeth whitener when they were developing Simply White ®.
Other manufacturers have chosen other forms of peroxides for their products. Colgate Simply White Night ® contains hydrogen peroxide (6.7%). Crest Night Effects ® utilizes sodium percarbonate peroxide (at a concentration of 19%, which is equivalent to 5.3% hydrogen peroxide).
How are paint-on teeth whiteners used? How long are they left on teeth?
Colgate Simply White ®
The directions for Colgate Simply White ® state that the product should be painted onto the front surface of the teeth being treated and then left in place for thirty minutes. Their recommendation is that Simply White ® should be applied twice a day.
Colgate Simply White Night ® and Crest Night Effects ®
In comparison, Colgate Simply White Night ® and Crest Night Effects ® are products that are intended to be applied before a person retires to bed. The bleaching treatment occurs overnight as the user sleeps.
Tips and pointers.
At the end of a bleaching treatment, it's good practice to use a toothbrush to remove any remaining whitener.
Paint-on teeth whiteners will tend to wear away or wash off of the tooth surfaces on which they have been applied. With most paint-on products, it seems that there is better adherence of the whitening film to the surface of the teeth if they have been dried off first (either 30 seconds of air drying or else wiping the teeth with a washcloth).
Before you decide to begin teeth whitening treatments...
The availability of paint-on teeth whiteners, as well as other forms of over-the-counter whitening products, can remove a valuable resource from the teeth whitening process. The resource we're referring to is your dentist. No individual could possibly know more about the topic of teeth whitening and how it specifically relates to you and your situation than your dentist.
Besides just providing your dental treatment, your dentist should also be considered to be your dental advisor. It is their obligation to share their knowledge and experience with you and advise you about the use of dental products, teeth whitening and otherwise, both those items obtained from over-the-counter sources and those products dispensed from their office.
Each and every teeth whitening processes should begin with an examination by your dentist. There are a number of issues that need to be addressed and documented. Some of the more important of these are an evaluation exploring why the tooth discoloration you have noticed exists. Is it normal or is it possibly the result of dental pathology? And an evaluation determining if the whitening goals you hope to achieve are realistic.
Peroxide-based teeth whitening products, such as paint-on teeth whiteners, will not typically produce a whitening effect for existing dental work (an exception to this rule can be teeth with dental veneers). Because of this it is important to have your dentist evaluate and identify where in your mouth dental restorations exist and also determine if it is anticipated that they will need to be replaced after the whitening process has been completed. There can be a considerable amount of treatment time and expense associated with replacing dental work.
Our pages that discuss tray-based teeth whitening products (Topics Index) address many of the concerns we have mentioned here. We strongly encourage you to read these pages so you understand the importance of having at least some degree of dentist involvement during your use of an over-the-counter whitening product.
