The infomercial for 30 Second Smile claims you only need to brush your teeth for just 30 seconds. Is this possible or is just a wild claim with no basis? In this article we look at the evidence.
On the infomercials you might have seen for 30 second smile it is claimed that you can clean your teeth in only 30 seconds. But how can that be? Especially when it is recommended by dentists that you brush your teeth for at least 2 minutes to get your teeth properly clean.
In studies into poor dental health, the biggest factor causing it, after diet, is human error when brushing teeth. There are two causes of this; bad technique and not enough time spent in cleaning the teeth (less than the recommended two minutes).
The manufacturer believes it addresses these with its electric toothbrush. A number of design features have been incorporated into the 30 second smile to support the infomercial's claim and address the issues of poor technique and not enough time.
The features and innovations that make the cleaning possible in 30 seconds and to get a better clean than conventional cleaning methods are: The toothbrush has dual heads. This means that you are able to clean both the top and bottom teeth at the same time.
Each dual head has three micro-heads that enable the front top, and back of the teeth to also be cleaned at the same time. It is recommended by the company that you first clean the teeth on one side of your mouth for 15 seconds, then swap over and clean your teeth on the other side of your mouth for a further 15 seconds, this gives a total of 30 seconds brushing time. Because the dual heads are made up of 3 micro-heads you are effectively cleaning a total 6 surfaces of your teeth at the same time, so by doing the mathematics means the 30 seconds of brushing is the equivalent of 3 minutes brushing with a conventional toothbrush.
The design of the toothbrush also contributes to getting a better clean. The micro-heads are angled at 45 degrees to each other. This is based on the method developed by Dr Bass method for teeth cleaning that is taught in Dentistry schools today. The 45 degree angle design results in cleaning of teeth and gums at the same time and results in healthier gums and healthier cleaner teeth.
The 30 second smile is a battery operated electric tooth brush. The heads move back and forth when switched on. The idea is for the operator (the person brushing their teeth) to gently hold the tooth brush and guide the tooth brush around their mouth. Too much pressure can damage the tooth brush and also may result in something less than an optimum clean.
In summary the 30 second smile addresses the issues of poor technique with the 45 degree angling of the micro-heads by almost making it impossible to brush your teeth any other way than the recommended Bass method. The dual head design along with the micro heads significantly reduces the time needed to actually brush teeth down to only 30 seconds with this being the equivalent of 3 minutes of conventional brushing.
