why is the roof of my mouth itch

It is understandably frustrating and uncomfortable when suddenly itching flares up on mouth roofs. Several possible reasons could be the cause of this discomfort. Wondering, “Why is the roof of my mouth itchy?” 

You are in the right place if you do. 

Please stick around and learn all the possible causes of an itchy mouth roof and how to treat it.

Why is the Roof of My Mouth Itchy?

An itchy mouth palate could be the result of many factors. 

Let us analyze the possible causes one by one. 

  1. Allergies

The primary symptom of catching an oral allergy is an unstoppable tingling sensation and itchiness in the mouth roof, accompanied by a few other symptoms depending on the type of allergy. 

These allergies range from a superficial level to a deadly level. Hence it would be best if you did not let your guard down.

Look for every way to reverse the condition. If the state seems significant, please head to the doctor immediately. 

What’s So Severe? 

We’ll see that as we dive in further. 

Let us discuss the types of allergies that may cause your itchy mouth roof. 

  1. Seasonal Allergies 

It is as exactly what the name suggests. Some people develop allergies in certain seasons due to changes in the atmosphere. 

Most patients are found allergic in the spring and fall. It is because the pollen, mold, dust, and other allergens in the air could enter your body and mess with your immune system, which can cause itching and tingling mouth roofs as a form of reaction. 

How Do You Know If you Have a Seasonal Allergy? 

Look for symptoms such as nasal congestion, itchiness in the nose and the throat, frequent sneezing, and watery eyes. 

Are these symptoms visible only around a certain period of the year? 

If yes, it is most likely that you have developed a seasonal allergy. 

How Do you Treat a Seasonal Allergy? 

Consult a doctor. If the allergy is mild, simple allergy medications will suffice. If it is more serious, the doctor will recommend the needed actions. 

Minimize your outdoor activities around the specific season you tend to develop allergies. 

Keep any doorways and shuttles close in your home. Wear a mask when going out. These steps can help you cut off contact with the allergens in the air. But it is not the solution. 

  1. Food Allergy 

Another type of allergy that might result in itching of the roof of your mouth is a food allergy. 

Certain people are allergic to certain foods/ certain ingredients, which can lead to an allergy. 

Common foods that trigger allergic reactions in people include nuts (of any type), meat, egg, seafood, tomato, eggplant, some fruits, etc. 

Observe if you develop itchiness after meal times or after you have eaten something. If you do, you must be allergic to that particular food or an ingredient in that specific food. 

Identify what triggers the allergy and keep those elements out of your zone if you cannot do that, head to a doctor and take an allergy test. 

The doctor will prescribe you an epi-pen to help you control the reactions. 

The only solution to food allergy is to never go near the food you are allergic to. You got to cut those off from your life. 

  1. Oral Allergy Syndrome (OAS)/ Pollen Fruit Syndrome (PFS) 

Oral allergy syndrome (aka pollen fruit syndrome) arises if you are allergic to certain fruits or pollen in the environment. 

The symptoms include;

  • Itchiness in the mouth roof.
  • A burning and tingling sensation.
  • Frequent feeling of pinpricks. 

Please consult a doctor to get it cured. You can treat the symptoms with over-the-counter medications for allergy relief if the symptoms are mild. 

Do not hesitate to reach a doctor if the symptoms are severe. 

  • Cold 

Another culprit responsible for your itchiness in the mouth roof could be cold. 

If you are experiencing symptoms of cold accompanied by itching mouth roof, cold is the cause.

What symptoms do a cold show?

You may have sneezing, coughing, sore throat, body ache, and mild fever. The top of the mouth will itch now and then as a result. 

Cold can last up to 2 weeks. However, with proper care, it will go away early. 

Drink plenty of water and stay hydrated. Give enough rest to your body. Take lozenges to soothe your mouth, roof, and throat. 

With cold, itchy mouth roof will diminish too. 

  • Infection 

Certain infections in the mouth can also result in an itchy mouth roof. 

Let us see what type of infections give rise to what kinds of symptoms. 

  1. Fungal Infection 

It is caused by an infection called yeast. 

It’s prevalent in people who wear external dental supports and those with vitamin deficiencies. (Commonly)

If you have a fungal (yeast) infection, you will experience itchiness in your lips, cheeks, tongue, mouth’s roof, and throat. You can also observe a white fluid-like residue in the tissues. 

Find ways and improve your hygiene orally. If you are a person that wears external prosthetics, please remove them nightly. Seek anti-fungal medications with the help of a professional. 

  1. Oral Thrush 

It is another infection that affects your oral well-being. It can happen in both babies and adults. 

Oral thrush will result in an itchy mouth roof. If this is the case, you will find yellowish-white bumps inside your mouth. 

You can treat this condition by improving oral hygiene and seeking anti-fungal medications. 

  • Hay Fever 

The name might fool you, but this is not a fever.

Hay fever is an allergy that includes mouth roof itching, ear ache/ itching, and other common symptoms of seasonal allergies. 

Using antihistamines or decongestants will help you minimize the reactions. Identify the responsible allergen and stay away from them. 

  • Anxiety 

Surprisingly, anxiety can give rise to an itchy mouth top too. 

The itchiness will accompany dizzy feelings, unusual sweat, heart racing, etc. 

Work on overcoming anxiety on your own or with the help of a professional. 


The roof of your mouth may itch due to different reasons. Identifying the cause and treating it is crucial for your overall health.
