What is oral thrush? Thrush is a fairly common infection of the mouth due to a yeast infection. Typically the infection lasts for about two weeks and appears as a white velvety patch, or sometimes red, raw skin.
What causes oral thrush and yeast infections? Thrush is due to an imbalance in the natural oral flora in the mouth.
Certain people are more likely to develop thrush than others. Common risk groups include:
- Denture wearers
- Immunocompromised (diabetes, HIV/AIDS)
- Poor oral hygiene
- Xerostomia (dry mouth)
- Use of steroid, antibiotic or asthma medication
People with suppressed immune systems are more likely to develop infections like oral thrush. Diabetics may have a difficult time managing the infection due to elevated blood sugar levels. Because yeast feeds off of sugar, imbalances in diabetics may make the infection worsen. Typically most of the above listed factors are the primary causes for oral thrush. (1)
Signs And Symptoms
Oral thrush symptoms may appear as:
- White velvety patches in the mouth
- Red, raw tissues
- Sores in the corners of the mouth where upper and lower lips meet
- Sores on the central, back portion of the tongue
Most yeast infections are not painful, but they may be uncomfortable in some people depending on the severity.
Dangers And Health Risks (If Any)
It is very rare for oral thrush infections to cause severe adverse reactions although it is worth mentioning that severe infections that are uncontrolled may possibly place other parts of the body at risk due to spread of infection through the touch or cardiovascular system. Examples of increased secondary infection sites are the eyes, esophagus, heart and brain.
How To Prevent Oral Thrush
Practicing good oral hygiene and maintaining a healthy lifestyle are the best ways to prevent oral thrush or yeast infections. Some simple ways to prevent oral thrush include:
- Practice good oral hygiene every day – brush, rinse, and floss
- Use pure botanical ingredients to kill the bad bacteria that lead to oral health problems
- Limit the use of antibiotic or steroid medication
- Give up smoking
- Replace your toothbrush frequently or after illnesses
- Remove dentures and clean them thoroughly each day
- Manage blood sugar levels
Oral thrush treatment can be through conventional or home remedies. Natural, over-the-counter treatments to get rid of oral thrush are typically successful but professional intervention may be needed if the infection is too severe.
Your dentist will most likely recommend that you use preventive home remedies to help clear up your fungal thrush infection. For severe cases of oral thrush, your dentist or doctor may recommend:
- Prescription antifungal medication
- Topical medication in the form of a mouth rinse
Home remedies for oral thrush include:
- The use of essential oils (2)
- Decreased sugar intake (yeast thrives on sugar)
- Increased intake of yogurt or acidophilus
- Giving up smoking
Oral Thrush In Babies
It is very common for young infants or babies to develop yeast infections or thrush in the mouth. This may be due to breastfeeding by a mother who is taking antibiotics, poor hygiene of bottle nipples or pacifiers, or in some cases from unknown reasons.
Always keep your child’s mouth clean, as well as any nipples or pacifiers that they use. Infants can have their mouth cleaned with warm water on a soft washcloth, gently wiping the tongue, roof of mouth, gums and inside of the cheeks. Mothers who breastfeed will want to use good hygiene habits to prevent spread of infection to their child, and treat any yeast infections in themselves appropriately.
Treatment And Remedies
Infants that develop oral thrush should have all of their pacifiers or bottle nipples sterilized or thrown away. Using a soft washcloth to wipe the child’s mouth and remove some of the bacteria by improving hygiene can help the infection go away.
In severe cases, prescription medication such as pilocarpine or cevimeline may be used to manage xerostomia and get rid of dry mouth.
