A professional dental cleaning removes all the plaque and tartar you are not able to remove at home. Even dentists and hygienists get regular cleanings!
Will it hurt?
Teeth cleanings should not hurt. You might experience discomfort, but it all depends on how many years it has been since your last cleaning and what other conditions are present in your mouth such as gingival inflammation, periodontal disease, infected teeth, etc, all of which can lead to discomfort. You may experience some sensitivity afterwards, but it should go away in a few days.
How often should I get a cleaning?
A professional dental cleaning is recommended at least two times a year, depending on the health of your teeth. Your hygienist and doctor will make a personalized recommendation for you and your oral health!
