Your mouth is a complicated ecosystem of components that work together to allow you to speak, chew, swallow and a host of other important functions. And as with many other intricate organisms, complications can arise. Mouth sores are some of them. These ulcers are one of the most commonplace lesions in the mouth. 

At the office of Bridgeport, we are enthusiastic about treating your oral health. It’s as important to our dentists as it is to you. In addition to the high-quality, comprehensive dental care we provide, we also have a welcoming, patient-focused environment in which each client will feel at ease.

Yes, mouth sores can be painful, annoying and unattractive, but they’re frequently innocuous and will clear up on their own in a six to seven days. But if they don’t resolve themselves after a few weeks, return often or if different symptoms start to show up, see your dentist for a thorough assessment of the situation. 

Up to one out of five people have recurring mouth sores. Some of the reasons behind them include biting the inner cheek, irritation from an orthodontic appliance, certain medications, sensitivity to chemicals, a disease or a side effect to chemotherapy. A canker sore, which is also called an aphthous ulcer, is a painful ulcer crater in the lining of the mouth. One might crop up when you are feeling emotional stress, experiencing hormonal changes or suffering from insomnia. 

Also, a few underlying conditions can cause ulcers. Among them are Crohn’s disease, celiac disease, nutritional deficiencies (B12, folic acid or iron), a compromised immune system disease such as HIV, lupus or reactive arthritis) and particular viruses (chickenpox, herpes simplex virus-1). It’s rare but possible that a persistent mouth sore could signal oral cancer, in which case a biopsy would be taken. 


At the office of Bridgeport, our elite team of dental professionals has the ability, focus and flexibility to demonstrate unparalleled professional knowledge. Our high-tech, cutting-edge diagnostic equipment will give us an overall view of the health of every aspect your mouth and teeth. Please don’t hesitate to contact us for an appointment.
