World War II paved the way for medical science to radically expand but certain developments like modern dental equipment and techniques for dentistry only provided gains to related fields leaving the rest empty handed. Regular visits to the dentist can now be achieved without any form of distress. Earlier periods can provide the necessary evidence that can explain why people had a fear of dentists. The same situation applied to other medical practitioners considering that this was a period where anesthetics and modern tools did not exist yet.

People have been scared of dental treatment for so long that psychiatrists wanted to know what causes them to fear the dentist and they concluded that the fear is caused by a person expecting to feel an amount of pain while being worked on and not necessarily because of the actual discomfort. People may be less afraid of the dentist if there were advancements in the dental industry that would be able to make their visit more enjoyable.

The practice of dentistry has been exposed to numerous changes including the development of high speed cutting equipment that is complemented by new dental techniques. There is one dentistry school that acquired one of these machines and they are introducing the technology to their students. No significant change happened when it came to the speed that dental instruments ran on and this was considering a timeline starting when electric motors were utilized in dentistry and extending to as far as the days following the Second World War. Determining the kind of dental equipment relied on the category it belonged to namely high or ultra high speed. When there is an ultra high speed dental instrument it will probably run in excess of two hundred thousand revolutions per minute.

Students of dentistry need to learn about these kinds of equipment because they will be practitioners in the future and this knowledge will allow them to provide better dental care. Having high speed dental instruments allow for maximum performance during procedures without as much pain. Preparing cavities is made simple as dentists now have a lightweight instrument that is easy to guide. Compared to earlier practices this new tool will now lessen the time it would take for a dentist to prepare a cavity. Dental appointments may actually be an event looked forward to and this is important for patients. With discomfort eliminated, the public will not hesitate to have their teeth checked regularly, thereby preventing an unattractive appearance and untimely loss of the use of the teeth. To be able to maximize the lifespan of teeth a person needs to regularly maintain them.

When people started practicing dentistry preparing cavities involved dentists making use of highly unsophisticated pieces of equipment and undeveloped techniques. Gouges and chisels were the main instruments of the dentist. Early tools also included the finger drill and this was actually the first dental drill making use of a ring so that the dentist could wear it on his finger. About two and a half centuries ago the civilized world made use of such instrument known as the jeweler's bow drill and this was a rather popular tool for dentists at the time. The design of this dental instrument required moving a bow back and forth to turn the handle carrying the drill. The string of the bow was looped around the drill to furnish the power.

There, are many situations in the practice of dentistry where ultra speeds are not desirable. Teeth are cleansed better, fillings are easier polished, and decay removal is a breeze when dentists make use of high speeds.
