A cleaning is a simple treatment that preserves your oral health and prevents potential damage from bacteria. The American Dental Association recommends coming in for a dental cleaning every 6 months. However, patients who are more prone to gingivitis are recommended to come in more often, every three to four months, to prevent infections. This is also recommended for patients with dental implants. A cleaning is not just for the purpose of removing build up and plaque. During your appointment your dentist will also do a full oral examination to check for signs of cavities and more serious dental issues, even oral cancers.
