White Tooth Dental Takeaways:
Gingivitis is a very common disease but fortunately, it is reversible and “curable” - with proper care at home and by seeing your dentist as often as recommended! It is important for us to do our best to control gingivitis because we want to so what we can to prevent the progression to the more severe, irreversible, “incurable” form of gum disease called periodontitis (the loss of tooth-supporting bone).
It is important to note that gingivitis (and periodontitis) are multi factorial diseases and though thorough oral hygiene using correct technique is a very important part of helping to control them, some people are predisposed to inflammation and we may need to consider other tools to help.
