2. Canker sores, also known as aphthous
ulcers are small, round sores that occur in
the mouth that are generally very painful.

3. Symptoms include fever, swollen lymph
nodes, physical sluggishness, general sores in
your mouth, tingling and general discomfort.
Pain usually goes away in 7-10 days. Can take
1-3 weeks for a canker sore to completely heal.

4. Canker sores can
be caused by
emotional
stress, lack of
certain vitamins
and minerals in
the diet, menstrual
periods, hormonal
changes, food
allergies, acidic
foods, braces or
dentures, and
impaired immune
systems.

5. Anyone can get canker sores, though it is
more common in women than men. They
may run in families. They can occur at any
time there is no specific time of year when
they occur more often.

6. Canker sores are not cold sores. Cold sores are an
extension of the herpes virus, while canker sores are
a common form of a mouth ulcer, and may come
with a viral infection. Cold sores are also usually
found on the outside of the mouth, while canker
sores occur on the inside.

7. Treatment is not typically necessary in most
cases, they typically go away by themselves. But if
you do have one, you should not eat spicy
foods, and mild mouthwash or salt water might
help. Over the counter medicines might also help to
soothe the painful area. If its severe enough, you
can get a prescription.

8. To prevent a
bacterial
infection and
reduce your
chances of
getting a
canker
sore, brush and
floss your teeth
regularly, and
get routine
dental
checkups.

9. Canker sores are not contagious. But
health care professionals advise
against kissing and sharing drinks with
people that have canker sores just in
case.
