Plaque is the soft mat of germs that grow on your teeth, while calculus (tartar) is the hard growth of bacteria on our teeth. Most, if not all of us, get varying amounts of plaque and calculus on our teeth, regardless how well we brush and floss.
That is why we need to have our teeth professionally cleaned and polished. This helps keep gums and teeth healthy and helps improve bad breath (halitosis).
Professional cleaning helps reduce gingivitis (inflamed gums), bleeding gums and periodontitis (destructive gum disease).There is evidence that unhealthy gums are linked to medical conditions such as heart disease, so the need to have clean teeth is more important than ever.
And remember, a dentist professionally cleaning your teeth makes them look and feel great.
