Oral issues


Hello, doctor.
I would like to ask why I have been experiencing an unusual taste in my mouth for the past week (sometimes it feels sour, but it doesn't seem to be).
My tongue occasionally feels prickly.
How can I improve this condition?

Amy, 20~29 year old female. Ask Date: 2017/08/09

Dr. Chen Taicheng reply Family Medicine


● If you have recently taken medication, such as antibiotics, it may sometimes cause changes in taste, which will gradually improve after discontinuation.
● Oral malodor should also consider the possibility of sinusitis, gastroesophageal reflux, excessive salivation, or oral hygiene issues; for tongue discomfort, observe for any ulcers or other lesions, and try to maintain a balanced diet and supplement with vitamins, which should lead to gradual improvement.
If discomfort persists, please consult an otolaryngologist.
Wishing you good health, Dr.

More Info


Bad breath, also known as halitosis, and tongue pain can be symptoms of various underlying oral health issues. Understanding the causes and potential solutions is essential for effective management.


Causes of Bad Breath
1. Poor Oral Hygiene: The most common cause of bad breath is inadequate oral hygiene. When food particles remain in the mouth, they can decay and produce foul odors. Bacteria that thrive in the mouth can also contribute to bad breath by breaking down food particles and releasing sulfur compounds.

2. Dental Issues: Conditions such as gum disease (gingivitis or periodontitis), tooth decay, or abscesses can lead to persistent bad breath. These conditions create an environment where bacteria can flourish, leading to unpleasant odors.

3. Dry Mouth: Saliva plays a crucial role in washing away food particles and bacteria. A condition known as xerostomia, or dry mouth, can result from various factors, including medications, dehydration, or certain medical conditions. When the mouth is dry, bacteria can thrive, leading to bad breath.

4. Diet: Certain foods, such as garlic, onions, and spicy foods, can contribute to bad breath. Additionally, diets low in carbohydrates can lead to ketosis, which can also produce a distinctive odor.

5. Medical Conditions: Some systemic conditions, such as diabetes, liver disease, or respiratory infections, can manifest as bad breath. If the odor persists despite good oral hygiene, it may be worth consulting a healthcare professional.


Causes of Tongue Pain
1. Irritation or Injury: Biting the tongue or irritation from sharp teeth can cause localized pain. If you have misaligned teeth or dental work that is rough, it may lead to tongue discomfort.

2. Oral Thrush: A fungal infection in the mouth can cause white patches on the tongue and lead to pain or discomfort. This condition is more common in individuals with weakened immune systems or those taking certain medications.

3. Nutritional Deficiencies: Deficiencies in vitamins, particularly B vitamins, iron, or folic acid, can lead to a sore or painful tongue.

4. Allergic Reactions: Allergies to certain foods or dental products can cause inflammation and pain in the tongue.

5. Burning Mouth Syndrome: This condition is characterized by a burning sensation in the mouth, including the tongue, without an obvious cause. It may be associated with hormonal changes, anxiety, or certain medications.


Solutions and Recommendations
1. Improve Oral Hygiene: Brush your teeth at least twice a day and floss daily. Consider using an antibacterial mouthwash to help reduce bacteria in the mouth. Don’t forget to brush your tongue gently to remove bacteria and food particles.

2. Stay Hydrated: Drink plenty of water throughout the day to help keep your mouth moist and wash away food particles. If you suffer from dry mouth, consider using saliva substitutes or chewing sugar-free gum to stimulate saliva production.

3. Regular Dental Check-ups: Schedule regular visits to your dentist for cleanings and check-ups. This will help identify and treat any dental issues that may be contributing to bad breath or tongue pain.

4. Dietary Adjustments: Pay attention to your diet. Reducing the intake of odor-causing foods and ensuring a balanced diet rich in vitamins and minerals can help improve oral health.

5. Consult a Healthcare Professional: If bad breath or tongue pain persists despite good oral hygiene, it’s essential to consult a dentist or a healthcare provider. They can help identify any underlying conditions that may need treatment.

In summary, bad breath and tongue pain can stem from various causes, including poor oral hygiene, dental issues, dry mouth, dietary factors, and systemic health conditions. By improving oral hygiene, staying hydrated, and seeking professional advice when necessary, you can effectively manage these symptoms and improve your overall oral health.
