Canker sores and cold sores are two common types of mouth sores. Canker sores appear as small ulcers inside the mouth, on areas like the tongue or inner cheeks, while cold sores appear as blisters outside the mouth, usually on or around the lips. Both can cause pain when eating or talking. Canker sores are not infectious, but cold sores, which are caused by the herpes simplex virus, can be spread from person to person. While there is no cure, home remedies can help speed healing for both types of sores.

1. Mouth Sores : Canker and Cold Sores, Symptoms,
Causes and Treatment
Mouth sores can be described as little cuts or ulcers in the mouth. They can originate in and around
the mouth. However, they have a tendency to heal on their own within a week or two. The sores
may have a colour of dark red or may have small white particles in the middle side. Sores can
become infected and cause bleeding. There are different types of causes responsible for mouth
sores. They can happen by infections of bacteria, radiation treatments to the neck and head area,
dehydration, oxygen therapy, poor mouth care, irritation of a loose orthodontic wire: a denture that
has a sharp edge from a broken tooth or filling or the one that doesn’t fit.

2. Those who pursue items related to tobacco or alcohol, who have a lack of
proteins and vitamin are also prone towards mouth sores. As we said that the
healing process might not take a long time, but they can prove to be very painful
and lead towards dehydration, weight loss or poor eating. Mouth sores are
basically divided into two parts, i.e., canker sores and cold sores. Both of them
have been mentioned below.

3. Canker Sores And Cold Sores
When the weather comes into its colder state, a person is more likely to get canker or cold sores.
However, they are different from each other but contain almost similar trigger like facial trauma,
stress, hormonal changes and can be painful. Their treatments are also the same, but it is necessary
to distinguish between both of them to ensure that a person gets the best treatment available.
If we break them down, we will see that both of them are different conditions with similar causes.
Our mouth is an outstanding measure of the health of our body’s immune system. We will tell you
about both the sores in a detailed manner so that you will get to know about their causes and
treatments.

4. About Cold Sores
Cold sores are captured at the outside part of the mouth. It is sometimes known as a
fever blister. It mainly develops as one or different red, blistered areas on the lips.
Despite their name, they are not caused by common cold. They typically result from
a viral infection named herpes simplex virus (HSV). They will appear clearly in the
initial time then become cloudy.

5. Cold sores contain mainly three types of development in which the first one will be
itching, tingling, and burning. Often, people may realize this type of sore coming on
one or two days before it actually takes place. The second development will be
blisters. A breakout appears and small clusters of blisters will take place on different
areas of the face. In the end, there comes crusting, scabbing and oozing. These types
of sores may merge and burst, that leaves shallow open sores which crust over.
There are some other symptoms like headache, muscle aches, sore throat, and
lymph nodes.

6. Causes
One of the major causes of cold sores is the herpes simplex virus (HSV). Unfortunately, the sores
are infectious when they are open. It means that the virus can spread when sharing drinks, utensils,
towels or by kissing. This type of virus stays in our body and is often triggered by things like
extreme pressure, weakened the immune system, stress or exhaustion. It can cause cold sore
outbreaks at any time.

7. Treatments
However, there is no cure for cold sores, but you can try out some home remedies to
speed up the healing time. Don’t try to touch the affected part as it can dry it out and
there become the chances of a bacterial infection. You can go for aloe vera as it
soothes the inflammation while also moisturizing the cold sore. Take things which are
rich in vitamins. You also need to take small bites at the time of eating to keep away
from any aggressive movements that can become responsible to open the cold sore.

8. About Canker Sores
Another variety of mouth sores that makes their way inside the mouth are canker sores. They are
twice as common in women and usually appear firstly at the age of ten to twenty. However, they
may appear as early as age two. Their targeted points are lips, cheeks, and tongue. They are a
type of small ulcers and have been classified into three different categories. The most common of
them are minor canker sores, the rest two that proves to be rare are major canker sores and
herpetiform canker sores.

9. Symptoms
These types of sores have a shape or oval or circle and have a yellow or white colour
that is surrounded by a red border. It can cause pain at the time of talking, drinking
or eating. The pain of these types of sores is rarely intolerable but is often
extremely annoying. They can make their shelter inside the tongue, at the base of
the gum line, anywhere in the soft tissue palate or inside the cheek or lip.
Causes
Canker sores can be caused by stress, some medicines, irritation caused by
orthodontic braces, mouth injury like biting the tongue or cheek, bacteria, viruses, a
weakened immune system, food allergies, etc.

10. Treatment
Unless the sores become too large, there is no need to visit the doctor. You can try
an oral pain reliever as ointments are difficult to place inside the mouth. Try to keep
the mouth clean by brushing, but don’t irritate the sore. Avoid spicy or salty food
when the sores are healing. There are some gels available in the market that can be
used to numb the sore and ease the pain.
Conclusion

the differences of both these sores in quick succession. Canker sores appear in the
soft tissues inside the mouth, while cold sores usually happen outside the mouth.
Canker sores are ulcers while cold sores are blisters. Canker sores aren’t infectious.
On the other hand, cold sores are very infectious. Both of them are two different
conditions which indicate that your immune system is low.
