A Look at Canker Sores and Other Common Oral Infections

Anyone can attest to the uncomfortable nature of canker sores and cold sores. Some have experienced the harsher oral infections of a tooth abscess, for which only a dentist can treat. Either way, there are common infections of the mouth, as well as relatively simple ways to treat them. Here’s a look at some of them.


Thrush, also known as candidiasis, is a fungal infection. White spots can form in the mouth or throat from an overgrowth of yeast. When the immune system has been weakened, possibly due to cancer treatments or diabetes, thrush has a higher risk of developing. Also, some steroids and antibiotics can contribute to the development of thrush. If you have a sore throat with cracks on the corners of your mouth, in addition to the white spots, consult your dentist or doctor. Typically, thrush will be treated with an antifungal medication.


Canker sores and cold sores are sometimes thought of as the same thing, though they are very different. Canker sores are non-contagious lesions that can develop anywhere on the soft tissue of the mouth. Cold sores are highly contagious red blisters that typically form around the lips, outside of the mouth. Both cold sores and cankers sores will heal by themselves in about a week or two. If the pain or irritation is very uncomfortable, there are over-the-counter topical anesthetics or mouth rinses that can help.

Bacterial Infections

Sialadenitis and tooth abscesses are caused by different bacterial infections. Sialadenitis occurs when the salivary gland has been interrupted, and the gland is painful and firm, possibly leaking pus. A tooth abscess comes from a bacterial infection in the tooth nerve. Both of these might require emergency dentists, antibiotics, or a root canal.
