Why is The Roof of My Mouth Yellow?

The simplest explanation for this discoloration is the food you’ve eaten. Certain foods and drinks, like coffee, tea, or curry can stain the roof of your mouth.

Sometimes, the yellowish appearance is caused by yellow bumps called Fordyce granules. These bumps can appear on the roof of your mouth, but they’re not dangerous.

Other Possible Reasons For A Yellow Palate

If the yellowish appearance isn’t caused by the reasons we mentioned above, it might be caused by certain conditions:

  • Poor oral hygiene — Plaque buildup can turn yellow if not brushed and flossed away thoroughly. 
  • Oral thrush — This yeast infection causes white, red, or yellowish patches. It's more common in those with weakened immune systems or after antibiotics.
  • Canker sores Small, painful ulcers that appear inside the mouth, including the palate. Canker sores may appear white, red, or yellow.
  • Infections — Gum infections or respiratory infections can sometimes cause yellowish patches or swelling.
  • Systemic issues — Very rarely, liver problems (jaundice) can cause yellowing throughout the body, including the mouth.

What Should You Do If Your Palate is Yellow?

First, don’t panic. Take note of your symptoms, including color changes, bumps, sores, and bad taste. This can help your dentist understand your condition.

Next, you should be extra thorough when brushing and flossing. The yellowing might be caused by poor oral hygiene, and brushing properly might solve it.

But getting a professional consultation is the only way to find out if it’s serious. Schedule an appointment with your dentist as soon as possible to see if you need treatment. 

How is A Yellow Palate Treated?

The treatment for a yellow palate depends on the cause. In some cases, like canker sores or poor oral hygiene, it can resolve on its own.

However, if the discoloration is caused by infections and other systemic conditions, it might require treatment. For example:

  • Oral issues — Infections like oral thrush might require antifungal medication. On the other hand, deep cleanings are typically needed to treat gum disease.
  • Quitting tobacco If the discoloration is related to tobacco, the only way to fix it is to quit. 
  • Jaundice Lifestyle changes, medication, or surgery might be necessary to treat jaundice. It may also resolve on its own as the liver heals.
  • Hypercarotenemia — Reduce the intake of carotene-rich foods like carrots, sweet potatoes, and pumpkins. This can also be resolved by treating underlying conditions like diabetes.
  • Amyloidosis — Treated with chemotherapy, targeted therapies, supportive care, and possibly stem cell transplant
  • Pyostomatitis Vegetans — Systemic/topical treatments and nutritional supplements can help manage this condition.

It’s important to understand that a specialist might be needed to treat you in some cases. For example, if the source of the discoloration is related to the skin, a dermatologist may be called in to help. 

Are There Natural Remedies For A Yellow Palate?

Unfortunately, no. There are no natural remedies to help with roof discoloration. 

Some claim that oil pulling draws out toxins related to discoloration, but no scientific evidence supports this. Meanwhile, salt water rinses may alleviate soreness, but they won’t cure infections or remove deep plaque.

Overall, the best way to get rid of a yellow palate is to prevent it with good oral hygiene and regular visits to your dentist. They can catch problems early on and treat them or refer you to someone who can.

How To Prevent The Roof of Your Mouth From Turning Yellow?

It’s important to understand that you can’t prevent everything that can cause the roof of your mouth to turn yellow. However, there are some basic habits that can help.

Here are some of our tips:

  • Brush your teeth at least twice daily for two minutes and floss to prevent plaque buildup.
  • Use a tongue scraper to remove bacteria from your tongue. 
  • Drinking plenty of water can promote saliva production, which helps wash away bacteria.
  • Crunchy fruits and vegetables can help keep your teeth clean and support a healthy oral cavity.
  • Avoid smoking. Tobacco use can stain your teeth and palate while increasing your risk of dry mouth. Smoking also puts you at risk of serious, long-term conditions.

The Importance of Proper Oral Hygiene and Care

Plaque is a film that builds up on your teeth, creating a yellowish appearance. If left untreated, plaque can harden into tartar, increasing the risk of tooth decay, gum disease, etc.

Fortunately, you can remove plaque at home by brushing your teeth properly. You should also floss and use mouthwash to reach areas of your mouth that your toothbrush can’t reach. 

However, even with good oral hygiene, you can’t clean some spots properly. Visiting your dentist regularly can help whiten your teeth and prevent plaque buildup.
