Your Preventative Anti-Aging Guide   By Carol Kim  In Your 30s:
Prevent yellow teeth.  Defense strategy Step 1: Rinse your mouth
with water immediately after eating and drinking to reduce
staining. Dark beverages such as coffee, red wine, and cola are
the most common offenders.  Step 2: Brush twice a day and floss
daily. This keeps teeth white by preventing cavities and plaque
buildup. The ideal time to floss is before bed. “You’re getting
all the debris out from the day and going to sleep with clean
gums and teeth,” says New York dentist Nancy Rosen, DMD (doctor
of dental medicine).  Step 3: If you notice surface stains,
gently brush with baking soda and water to remove discoloration.
