Mouth aches may be unexpected from juice fasting, but if you have certain conditions, mouth aches may be a common symptom. Burning mouth syndrome, which can occur when you consume too many acidic drinks, according to American Family Physician, could be a cause of the aching. Another possible cause of the mouth aching is oral allergy syndrome, a condition that’s related to hay fever that is triggered by consuming certain fruits, vegetables or nuts. Your doctor will determine the cause of you mouth aches and recommend treatment options.
Burning Mouth Syndrome
The cause of burning mouth syndrome is not fully understood, but the overconsumption of acidic beverages may trigger symptoms. The conditions may cause an aching and burning sensation in your cheeks, roof of your mouth, gums, lips and tongue after drinking fruit juices, according to the National Institute of Dental and Craniofacial Research. The condition is also referred to as glossodynia, burning lip syndrome and scalded mouth syndrome. Other symptoms may include loss of taste, soreness, dry mouth, increased thirst, changes in taste, numbness of any area of your mouth and pain.
Oral Allergy Syndrome
Oral allergy syndrome can cause mouth aches when you ingest certain fruit juices. If you have been diagnosed with hay fever, you are more likely to develop this condition. Hay fever is an allergic condition that mainly affects your sinuses, eyes and throat from a hypersensitivity to certain pollens. This condition can cause an aching or itching sensation in your mouth, lips, throat or roof of your mouth. Oprah.com states that this condition rarely leads to further complications, such as a severe allergic reaction or throat swelling.
Types of Juice
Oral allergy syndrome occurs because your immune system mistakes the proteins in certain juices as pollen, triggering a minor localized allergic reaction. For example, if you’re allergic to birch pollen, drinking apple, pear, cherry, plum prune, carrot, pepper, celery or peach juice can trigger mouth itching, aching and burning, according to the Children’s Hospital of Philadelphia. If you’re allergic to ragweed pollen, drinking honeydew, cucumber, watermelon or banana juice can trigger symptoms. Pineapple and papaya juice contain proteolytic enzymes which can cause mouth ulcers, according to Paylesschemists.com.
Discuss your symptoms with your doctor because you may need to discontinue the juice fast. In some cases, cooking the juice may prevent symptoms from developing because the protein structures of the fruits and vegetables are modified when cooked. You may also find that pasteurized juices do not trigger you symptoms.
