Hi. Teeth cleaning is advised once every 6 months. All the plaque and deposits that get accumulated will be removed during a cleaning session. Along with that, you might need additional gum treatment according to your case, which will be decided by your dentist
Next Steps
please visit a dentist for a cleaning, since it has been 6 months since your last cleaning. If your dentist feels the need for any further treatment, he will advise you gum treatment which is carried out by a gum specialist
Health Tips
Start doing brushing twice a day, warm saline gargles twice a day and regular cleaning every 6 months. Hope this helps :)
