Scaling removes plaque and tartar and polishing removes stains and remaining plaque while smoothening and shining teeth so that dental plaque cannot attach easily to tooth surfaces.

​

Polishing may then be followed by a fluoride gel or foam treatment to reduce post-scaling sensitivity and reduce the risk of tooth decay.

​

Dental scaling and polishing is recommended to prevent tooth decay and gum disease, and may be necessary every six months depending on the oral condition of a patient.
