Why does a dentist have to use the drill to treat cavities?

Teeth are the hardest substance in the human body. When a tooth gets a cavity it means that part of the tooth is soft where it was once hard. This soft part of the tooth needs to

be removed otherwise, with time, it can get bigger and spread to the rest of the tooth and need a more invasive procedure. Usually a drill is used to remove this soft part of the tooth until only hard tooth structure is left. The dentist will prepare the tooth according to the type of filling that will be used to fill the space of where the cavity use to be.

A tooth "cavity" is termed when you have decay on your tooth. The dentist has to "drill" it to remove the decay area. After that, tooth can be directly filled with amalgam "silver" material or resin "white" composite. In cases where the cavity occupies majority of the tooth, repair can be made indirectly with a porcelain inlay, onlay, or crown.

Because a cavity is a hole in your tooth, and there's nasty stuff (decay) in that hole that needs to be removed. However, the "cavity hole" is really not one that dentist can work with - it's often too small for dentist to get in there and do what they have to do. So dentist need to further drill the hole to make the workspace big enough to clean out the decay. Then use a filling on the (larger) hole they made before.

All of these reasons explain why dentists need drills to treat cavities. If you need treatment for cavities, you also need to pay attention to whether the dental hospital where you are being treated has good dental equipment . For example, you need a good dental X-ray machine to see a specific situation inside a tooth
