Aphthous ulcers: Aphthous stomatitis involving the common canker sore can occur in up to 15% of americans, and may involve some bacteria like staph epidermidis. However, similar-appearing aphthous ulcers can be seen with herpes, crohn's disease, and other systemic disorders, if you have multiple aphthous ulcers or frequently recurring ones please have the lesions checked out.

Prevention: The reaction of people to acidic foods is very variable. Some people are just more susceptible to reactions to acidic foods and drinks, like orange juice, pineapple juice, fruits, tomatoes, and others. Stress and anxiety also create problems sometimes. As far as i know, prevention is difficult except for keeping track of what you eat/drink and when you get the sores.

Quit entirely.: There are so many changes going on within the cells that are exposed to smoking that it is often hard to predict what is causing what, or if there is only a temporal relationship, and not a causative association. Quit smoking entirely. And use whatever help or means you can to accomplish it. The most important step, and the one that will probably making quitting successful is the decision to quit.

Prevent trigger: See prior answers relating to these for much more discussion. Each person usually finds that certain things trigger them, e.g. Citrus fruits, lack of sleep, weight loss, iron, vitamin B12 or Folic Acid deficiency, trauma, braces. There are some systemic diseases associated with these: crohn's, behcets, celiac disease. Also think of hot drinks. Oragel topically or antiviral rx early on may help.

Could be both.: Herpes simplex of the mouth is a common cause of painful, recurrent ulcerations, caused by the virus, that stays indolent in the mouths/lips, and then when triggered by a 'cold' or sun or certain foods, etc, becomes an active lesion. Aphthous ulcer is a more general term, which is associated with many different causes, but not one cause.

Canker sore.: An aphthous ulcer is also known as a canker sore, often a painful circular lesion inside the mouth. It does not have one specific cause, but it can be brought on by many triggers such as stress, infection, vitamin deficiencies, or immune system abnormalities. Other than being painful, they are harmless and can be treated with topical oral agents.
