Sores on Roof of Mouth

Bumps on roof of your mouth are just a burn, especially after a hot meal. This phenomenon is called the “pizza palate” as it is said to be caused by fresh slices of pizza leading to irritation in your mouth. However, pizza isn’t the only food which burns your mouth; any hot food may also have this effect. Hot drinks, such as tea, can cause similar burns.

A burned palate heals by itself within a period of about seven days. To ease your discomfort in meantime, stick to taking soft foods or just cool drinks.

If the pain is very much severe, then your dentist might recommend using a product that can ease the sensation in sores and thus promote quicker healing. If the area is still sore after several days, see your dentist again.

  1. Canker Sores

Canker sores can develop on inside of your cheeks, but they can also be felt on roof of mouth also. Canker sores are round masses whose origins depend on case.

Generally, people can develop about three canker sores per instance, but some people might develop upwards of more sores at one given time.

These sores hurt for a little over seven days, then disappear completely after a period of about ten days. While you wait for healing of your mouth, you can also benefit from eating bland foods so as to avoid irritation of the sores.

Your dentist can also prescribe a pain-relieving gel for your application to your sores during recovery process. If your sores haven’t healed after these ten days, ensure that they are checked out by your dentist.

These sores usually present as painful, fluid-filled blisters; which later rupture and crust over as just less-painful lesions.

Cold sores can also become crustier within a period of about four days of appearing, and heal completely after about 10 days. While healing, avoid touching them. If the sores don’t disappear by themselves, as you know, your dentist may be of help.

  1. Oral Cancer

Although some of sores which form on roof of mouth are harmless, not all of them should be left alone. Sores on roof of mouth might sometimes be a symptom of oral cancer.

And if you have a sore on roof of your mouth which hasn’t healed after a period of about ten days, you are required to see your dentist immediately for proper evaluation.

Oral cancer is treatable when it’s detected early, so it’s crucial to bring suspicious sores to your dentist’s attention.

If your dentist suspects a sore to be cancerous, he will send you to an oral surgeon for an evaluation and perform a biopsy of tissue. If cancer is detected, treatment starts quickly. This treatment involves surgically getting rid of the cancerous sore, and chemotherapy so as to be sure it doesn’t affect several other cells.

If you develop a sore in roof of mouth tissue, there’s no need to assume the cause is out of your control. These sores can have several drivers that ranges from harmless to the invasive.

Most of them disappear on their own, but a sore on roof of your mouth which doesn’t heal within a period of two weeks is the perfect reason to see your dentist for an evaluation.
