You can expect your dental cleaning to last between 30 minutes and an hour. Typically, a trained hygienist will do the cleaning, and a dentist may come in for an exam at the end. Most people find that dental cleanings are painless, and do not cause any discomfort.
There are two important steps to a dental cleaning. The first step is scaling the teeth, whereby the hygienist will remove the plaque and tartar from the tooth surfaces. This can be performed by hand or with electric scalers depending on the hygienist's preference. Typically, the hygienist will also dig into the pockets of the gums to remove any plaque buildup there.
The second step is polishing to remove any final plaque and buff the teeth. Polishers generally have several different sized heads to clean hard to reach places.
