Our mouth is an incredible ecosystem that hosts a vast number of microorganisms – some beneficial, others potentially harmful. When everything functions properly, our body is able to keep these “guests” in balance, preventing the spread of the more dangerous ones. Sometimes, however, things don’t go as they should: following other illnesses, nutritional deficiencies, the use of certain medications, or when our immune system is weakened, this balance can break down. In such cases, the mouth becomes the stage for infections and disease.
Mouth Ulcers and Oral Thrush: Causes and Symptoms
Mouth ulcers and oral thrush are among the most common conditions affecting the oral cavity. Ulcers are familiar to many: small, round or oval whitish sores surrounded by a red, inflamed ring that can cause significant pain. They typically appear on the inside of the lips or on the tongue, but may also develop on the inner cheeks or gums.
Identifying the exact cause of an ulcer is not always easy. Stress is a well‑known trigger, and women tend to be affected more often than men. Other factors include certain foods (too hot, spicy, crunchy, or allergenic), smoking, alcohol consumption, or the use of overly aggressive mouthwashes, all of which can irritate the oral mucosa. Systemic diseases, as well as medications such as antibiotics or corticosteroids that weaken the immune system, can also make the mouth more susceptible to ulcers and infections.
Oral thrush, on the other hand, is an infection caused by the excessive growth of a fungus naturally present in the body: Candida albicans. This condition is characterized by white patches on the tongue, cheeks, and palate. It is especially common in infants and young children – known as “thrush” – but can also affect adults.
These conditions may require medical attention, with a doctor prescribing specific treatments (antibacterial, antifungal, or anti‑inflammatory medications) to relieve discomfort and resolve the problem.
While professional consultation is essential for effective therapy, nature and good daily habits can also provide valuable support in managing stomatitis and promoting healing.
Healthy Habits
Maintaining oral health requires consistent attention in everyday life.
First and foremost, it’s important to stay away from the usual “bad habits” that can damage the oral mucosa. Smoking is one of the main causes of chronic inflammation in the mouth, which, over time, can lead to more serious diseases.
Alcoholic beverages, in addition to dehydrating the oral mucosa and making it more prone to ulcers and sores, are also rich in sugars – the favorite “food” of Candida.
The key to overcoming Candida is maintaining the correct pH balance in the oral cavity.
Harmful microorganisms, such as Candida albicans, thrive in an acidic environment, while a neutral pH creates conditions that are unfavorable for their growth.
Here saliva plays a crucial role: it acts as a powerful buffer, capable of restoring the mouth’s pH to neutrality within just a few minutes after consuming foods and drinks that tend to acidify it.
This is why daily oral hygiene must never be neglected. Brushing teeth after every meal helps restore neutral pH and removes food residues that microorganisms could feed on.
Don’t forget to schedule regular dental check‑ups: professional cleaning is the foundation of a healthy mouth, and routine visits help monitor oral health and detect potential issues before they become serious.
Healthy Eating
Nutrition plays a key role in oral health. Candida, for example, thrives on foods rich in sugar and carbohydrates. Limiting their intake can help restore the natural balance in which this microorganism lives, making recovery easier and faster.
But that’s not all! A balanced diet rich in vitamins and fiber benefits the entire body. Careful, though – not to overdo fruit and fruit juices: they contain fructose, a type of sugar.
A stronger immune system is our first line of defense against inflammation. Mouth ulcers can even be an early sign of vitamin deficiencies. If you suspect this, consult your doctor or a nutritionist.
Consuming probiotic‑rich products, such as yogurt or fermented drinks, can also support intestinal flora. When “good bacteria” are healthy, they help maintain balance and fight the spread of harmful microorganisms, such as Candida or the bacteria responsible for ulcers.
Support from Nature
When diet alone is not enough to meet the body’s needs, supplements can help. Zinc‑based supplements, in particular, may reduce the incidence of oral ulcers and speed up healing.
Inflamed mucosa needs soothing. Traditional natural remedies can provide relief from the burning caused by oral thrush and ulcers: a simple solution of water and salt, or water and baking soda, can ease pain and accelerate healing. These solutions also make the mouth’s ecosystem less welcoming to infection‑causing microorganisms.
Cariex®, with its formula based on baking soda, xylitol, and hyaluronic acid (naturally present in mucosa), enhances saliva’s effectiveness in maintaining a healthy mouth. Thanks to its rapid action, Cariex® immediately restores oral pH, reducing acidity and creating an environment unsuitable for harmful microorganisms. Its effect lasts about forty minutes, giving the mouth time to regulate pH naturally and covering the window needed for natural buffering mechanisms to take place. The spray formulation of Cariex®, easy to use even for younger patients, also creates a protective film inside the oral cavity. Its natural ingredients act directly on inflammation, soothing it and providing immediate relief.
