Tiny bumps on the palate (roof) of the mouth can be caused by several issues, are usually harmless and typically go away on their own without treatment, according to MD-Health. White bumps on the palate can be caused by smoking; mandibular torus or exostosis is marked by bumps on the palate or jaw and can be caused by food injuries, such as sharp foods becoming lodged in the mouth. Mucoceles can be marked by bumps on the palate when a salivary gland is blocked or cut.
Certain precautions can be taken to prevent irritations of the mouth palate, according to MD-Health. Although these irritations are harmless and often heal quickly on their own, they can be painful, meaning prevention methods may help avoid frequent occurrences.
Bumps caused by sharp, hard or hot foods can be avoided by consuming foods at the appropriate temperature. Avoiding troublesome foods, such as chips or other sharp foods, can prevent cuts and irritation of the palate that often result in bumps.
Canker sores can arise on the mouth palate and also tend to heal without treatment after a few weeks, but they can be treated with over-the-counter canker sore medication or with a salt water or mouthwash gargle.
