Dental Insurance Doesn't Like to Cover Deep Cleanings
But don't let that dissuade you, if you need this service.
It is needed for treatment of certain types of gum disease.
In gum disease, you get deposits of tartar or calculus on the root of the tooth. This calculus is made up of bacteria that are embedded in mineral deposits. It is highly irritating to your gums, and is associated with the deepening of pockets in your gum and the destruction of the bony support of your teeth.
Deep cleaning involves going into these pockets with instruments and cleaning out the calculus. When you have gum disease, it's important that these pockets be cleaned out thoroughly.
For financial reasons, dental insurance doesn't like to pay for this higher level service. They also often deny claims when these cleanings are done more often than every six months. But with gum disease, it is strongly recommended that this be done every three or four months, or sometimes even every two months.
