Quick Answer
A dental cleaning is a professional cleaning by a dentist or dental hygienist that removes bacteria, plaque and tartar a toothbrush can't reach. It helps prevent cavities and gum disease. Most dentists recommend a cleaning every six months. Most cleanings take 30 to 60 minutes and shouldn't hurt.
What the research says
Regular scale and polish mainly reduces tartar: a Cochrane review of 2 UK trials with 1,711 adults found routine 6- or 12-monthly scale and polish made little or no difference to gum inflammation or quality of life over 2 to 3 years, but modestly reduced tartar buildup (Lamont T et al., Cochrane Database of Systematic Reviews, 2018) [2]
Check-ups can be timed to your risk: in a Cochrane review of 2 trials with 1,736 people, those whose check-up intervals were based on their risk had the same cavities, gum bleeding and quality of life over 4 years as those seen every 6 months (Fee PA et al., Cochrane Database of Systematic Reviews, 2020) [3]
