So, there could be a few things going on, which is why it’s a great idea to visit us to get a better idea. Here are some issues that could be the culprit behind that awkward lump or bump in your mouth:

dental pain

Canker Sores

If you notice a few blisters in your mouth that are also sore or painful, then you could be dealing with canker sores. They can develop anywhere in the soft tissues of your mouth, from your gums and cheeks to your tongue. Most of them will go away on their own in a couple of weeks; however, if you have serious discomfort or if you develop canker sores often then it’s time to talk to our Kensington and Gaithersburg general dentists.

Mucous Cyst

This cyst, which is the result of blocked salivary glands, can develop anywhere in the mouth but is most commonly found on the lips. These cysts aren’t painful and, like canker sores, they will go away on their own. Why do these cysts forms? They are most often caused by repeatedly biting the lips or cheek.

An Abscess

If there is an injury or open wound in the gums or soft tissue of your mouth this easily allows bacteria to enter, which can lead to an infection. As a result, a pus-filled pocket forms on the gums. An abscess on the gums could also mean that you have an infection between your teeth and gums, which is more common in those with serious gum disease.

Oral Cancer

In rare instances, that abnormal new growth could be a sign of oral cancer. If the growth doesn’t go away in a couple weeks, if the growth gets worse, if the sore begins to bleed, if you notice a persistent sore throat or you also have trouble swallowing or chewing then it’s time to get yourself to the dentist right away for an evaluation.
