The roofs of the mouth can appear yellowish and this color change can have several possible causes. Common causes include poor oral hygiene, dry mouth, oral thrush, canker sores, and sometimes jaundice.
Oral hygiene is the most common reason for a yellow roof of the mouth. If left unhygienic, bacteria can thrive and turn the roof of the mouth and the tongue yellow due to the build-up of plaque and food particles.
Dry mouth, or xerostomia, is another cause for a yellow roof of the mouth. This occurs when the salivary glands do not produce enough saliva, resulting in a dryness in the mouth that allows bacteria to grow and disfigure the roof of the mouth.
Oral thrush is a yeast infection that can cause yellow patches on the roof of the mouth. This condition is more common in people with weakened immune systems.
Canker sores are small, painful ulcers that appear inside the mouth and can appear red or yellow on the roof of the mouth. While most canker sores disappear on their own within a few weeks, some may require medical attention.
Jaundice is a condition caused by the buildup of a yellow pigment called bilirubin, which is usually due to liver or gallbladder problems. This condition can also affect the roof of the mouth, making it appear yellow.
Treatment for a yellow roof of the mouth depends on the underlying cause. Poor oral hygiene, dry mouth, and oral thrush can usually be addressed with improved home oral care and regular dental check-ups. If the cause is an infection such as oral thrush or canker sores, medication may be necessary. Severe causes such as jaundice require medical attention and treatment.
If you notice any changes in the color of your roof of the mouth, it is important to consult with a dentist or oral surgeon for a thorough examination and treatment. By maintaining good oral hygiene and visiting the dentist regularly, the likelihood of your roof of the mouth appearing yellow can be minimized.
