A sore in the roof of your mouth can be quite painful, to say the least. The roof of your mouth is made up of two parts—a hard, bony palate near the “front” of your mouth, and the fleshier, softer part of the mouth which is at the “back” of your mouth and closer to the throat. As such, a sore in either area can not only be painful, but potentially obstruct parts of your mouth if big enough or be indicative of a larger problem.
There are a variety of potential causes for sores in the roof of your mouth, depending on the nature of the sores. For example, canker sores are particularly painful, and can show up anywhere in your mouth, including the roof—however, the precise cause of canker sores is unknown, as everything from T-cell issues to poor nutrition and other factors have been suggested. As such, a simple change to your diet—and perhaps some patience as you bear the pain—is all that you’ll need.
Cancerous sores can crop up in the roof of your mouth. These can be indicative of oral or throat cancer and, as such, are a cause of those cancers. If you find yourself dealing with such sores, you’ll want to contact a doctor immediately. While pain medications and other treatments can be given to lessen the pain if there is any, the real priority should be in treating these sores and the source of your cancer immediately. This will almost certainly involve finding a proper ophthalmologist and putting together a plan to beat your cancer which may or may not include chemotherapy or other treatments.
Particles resembling sores can appear near your adenoids if they’re inflamed, infected, or need to be removed. In the latter case, obviously removal is one form of treatment for your tonsillitis or adenoid issues—as well as plenty of ice cream afterwards.
There can be a wide variety of bumps and abrasions at the roof of your mouth which are simply the product of having accidentally had something strike the roof of your mouth or it becoming inflamed by other means. In such instances, no major medical treatment is generally necessary—warm water or and soup or cold water and ice cream (depending on the nature of the sore and your pain) should be enough to help you deal with the pain until it goes away on its own; if it persists, it may be one of the above conditions or another condition altogether, and you’ll want to schedule an appointment with your dentist as soon as possible.
