What are aphthous ulcers and canker sores?
They are the same thing! In some countries these mouth ulcers are called canker sores in the mouth. Generally, the correct medical term is "aphthous ulcer", and "canker sores in the mouth" is what patients call them.
They are not contagious, so you don't have to worry about spreading them to other people in any way. However, they can be very painful, and can interfere with eating and speaking, depending on where they are situated.
Canker sores in the mouth are:
Aphthous ulcers or "canker sores" in the mouth are very common indeed. About 20% of the general population get them at one time or another. Canker sores can also be known as aphthous stomatitis. This is just a medical term that means an inflamed mouth due to ulcers!
The tendency to get mouth ulcers appears to have a genetic origin - that means that getting mouth ulcers seems to run in families. If mom or dad tend to suffer from mouth ulcers, the chances are that their kids will, too. Some people are just more prone to getting these ulcers than others.
The size of the mouth ulcer depends on the type of ulcer.
What are the symptoms of aphthous ulcers?
Aphthous ulcers in the mouth usually crop up inside the cheeks or inside the lips. However, they can also appear almost anywhere inside the mouth and throat.
The ulcers begin as tiny red swellings (like tiny blisters) that usually burst within a day or two. The resulting sores are covered by a thin layer of white or yellow tissue, and usually have a red halo around them.
On average, the ulcers heal within two weeks without treatment, and without scarring. It's unusual to get a high temperature, and mouth ulcers do not generally have anything to do with any other medical condition.
Most people experience their first canker sores in the mouth between the ages of 10 and 20. But it is possible to get them at any age. How often you get canker sores varies considerably. Some lucky people only get them once or twice in a year. Other less fortunate folk can get an almost non-stop run of canker sores. As soon as one area heals up, another area breaks out.

What are the causes of mouth ulcers?
We don't know for sure. It seems to be a combination of things. This "triggering combination" is different for different people.
Recent research has shown a link between aphthous ulcers and a particular ingredient in just about EVERY toothpaste on the market.
It's called Sodium Lauryl Sulfate, and it's added to toothpastes to make them foam up a bit. But in some people it can trigger ulcers or canker sores.
The BEST toothpaste that does NOT contain Sodium Lauryl Sulfate is from TheraBreath. I recommend the standard TheraBreath toothpaste. This should help to PREVENT the ulcers from developing in the first place, if you are one of those people who are sensitive to Sodium Lauryl Sulfate.
Canker sores do not appear to be caused by a virus or bacteria. However, it is possible that some folk have a type of allergic reaction to a particular bacteria in their mouth.
What treatments are there for mouth ulcers?
There are NO specific treatments that I know of to make ulcers heal up more quickly. They will heal up in their own time. BUT there are a couple things that you can do to minimize the discomfort. Take a look at mouth ulcer treatment, which tells you about some things you can do at home.
Although aphthous ulcers can be very painful, they heal up on their own and normally don't cause any problems. However, as always, if you have canker sores in the mouth that don't heal within 10 - 14 days, get your dentist to check it out!
