Thanks for asking the query,
If you donot brush your teeth it causes plague and calculus deposition, inflammation of the gingiva
, bleeding gums
which causes growth of various bacterias which are released in the blood stream.
Few bacteria causes chronic infections and increases risk of heart attack
If you donot brush your teeth properly risk factor to heart diseases increases.
So i would advise you to maintain a good oral hygiene
Brush your teeth twice daily.
Use interdental cleaners, dental floss, antiseptic mouthwash rinses.
Hope you find this as helpful,
