Helping Your Child’s Oral Thrush At Home

Is Oral Thrush Caused by Antibiotics?

You can help your child’s oral thrush to heal by:

  • offering regular milk feeds – you may need to offer more if they are not taking as much as usual
  • feeding them bland foods – spicy or acidic foods could sting their mouth
  • keeping their hands clean so that the infection does not spread
  • sterilising any soothers or dummies regularly, as well as any toys they put in their mouth, such as teething rings
  • washing your hands after changing nappies and before any feeds

How Is Oral Thrush Diagnosed

Your doctor will usually diagnose oral thrush by your typical symptoms and the typical appearance in your mouth. No investigations are usually needed to diagnose oral thrush.

However, your doctor may sometimes suggest a blood test to look for certain conditions that may make you more likely to develop oral thrush. For example, a blood test to see if you are lacking iron, vitamin B12 or folate.

If oral thrush does not respond to treatment , your doctor may suggest that they take a sample from inside your mouth. The swab is then sent to the laboratory to be examined under a microscope. They can also try to grow the Candida in the laboratory.

Occasionally, a biopsy is needed to confirm a diagnosis of oral thrush. A small sample is taken from the white patches inside your mouth and this can be examined under a microscope.

Oral thrush in babies presents as a white coating on the tongue that resembles cottage cheese. A caregiver will not be able to rub the coating off easily. However, they will be able to scrape the coating off, leaving a red area.

Oral thrush in adults generally appears as thick, white, or cream-colored deposits on the mucous membrane of the mouth. The inside of the mouth may appear swollen and slightly red and may feature raised spots.

The white spots may join together to form larger ones, also known as plaques. These plaques may then take on a grayish or yellowish color.

Occasionally, the affected area simply becomes red and sore, with no detectable white spots.

If a person scrapes the cream or white-colored deposits, bleeding may occur.

Other symptoms include:

  • cracks at the corners of the mouth
  • an unpleasant taste
  • pain, such as a sore tongue or gum
  • difficulty eating or drinking

Individuals who wear dentures may have areas that are constantly red and swollen under their dentures. Poor oral hygiene or not taking the dentures out before going to sleep may increase the risk of oral thrush.

How Do You Treat Thrush After Taking Antibiotics

Vaginal thrush is an infection caused by an overgrowth of the yeast called Candida albicans. The yeasts are naturally occurring in the body but only in small amounts. Thrush can be really itchy, often causing irritation and vaginal discharge.

How can women get vaginal thrush from antibiotics?

Normally, there is a balanced mix of bacteria and yeast in the vagina. The former should dominate the latter in number.

Unfortunately, yeast infection on the mouth and vagina is common for women who recently took broad-spectrum antibiotics. This happens because the drugs kill both bad and healthy bacteria.

As a result, the number of healthy bacteria in the vagina decreases. Then, yeasts like Candida albicans grow uncontrollably and causes infection.

What are other causes of a vaginal yeast infection?

  • High alcohol intake

Symptoms of vaginal thrush include the following:

  • Redness and swelling

  • Creamy white lesions in the vagina

  • White discharge that is thick and cottage-cheese like in appearance

  • Burning sensation while urinating

It is easy to mistake the symptoms of vaginal thrush as that of bacterial vaginosis. Others may think of it as signs of STI. However, these are completely different medical conditions.

Thrush can affect women’s health if not treated properly. This is why it is important to get a diagnosis by a doctor.

What Is Oral Thrush

Thrush is an infection caused by a yeast germ called Candida. The mouth is a common site where Candida causes infection. Candidal infection in the mouth is called oral thrush.

See separate leaflets called Vaginal Thrush , Candidal Skin Infection and Nappy Rash for more details about these other types of thrush.

What Are The Symptoms Of Thrush

Thrush usually develops suddenly. A common sign is the presence of those creamy white, slightly raised lesions in your mouth usually on your tongue or inner cheeks. They can also be seen on the roof of your mouth, gums, tonsils or back of your throat. Other symptoms may be:

  • Redness and soreness inside and at the corners of your mouth.
  • Loss of ability to taste.
  • Cottony feeling in your mouth.

The lesions can hurt and may bleed a little when you scrape them or brush your teeth. In severe cases, the lesions can spread into your esophagus and cause:

  • Pain or difficulty swallowing.
  • A feeling that food gets stuck in the throat or mid-chest area.
  • Fever, if the infection spreads beyond the esophagus.

Thrush can spread to other parts of the body, including the lungs, liver and skin. This happens more often in people with cancer, HIV or other conditions that weaken the immune system.

Other Tips For Prevention

Cause of Oral Thrush

Follow these tips to reduce your risk of developing a yeast infection, regardless of whether youre taking antibiotics:

  • Change out of wet bathing suits and underwear as soon as possible. Yeast thrives in moist environments.
  • Avoid hot tubs and very hot baths. The only thing yeast loves more than a moist environment is a warm one.
  • Wear loose-fitting clothing. While theres no clear link between tight clothing and yeast infections, tight pants can increase heat and moisture around your vulva.
  • Wear breathable, cotton underwear. Cotton underwear can help keep things cool and dry down there.
  • Never douche.Douching removes healthy bacteria.
  • Avoid vaginal deodorant products. This includes sprays, powders, and scented pads and tampons.
  • If you have diabetes, keep your blood sugar under control.High blood sugar levels encourage yeast growth.

Adverse Effects Found But Potentially Under

Oral Thrush Causes: Antibiotics

A total of 45 trials were included in the review. Of these, 27 involved amoxicillin, 17 involved amoxicillin-clavulanic acid and one involved both drugs. These trials featured a total of 10,519 participants. Of these, 4,280 people received amoxicillin, 1,005 received amoxicillin-clavulanic acid and 5,234 received a placebo.

Antibiotics were prescribed for a range of situations within the trials:

  • Primary care 33%
  • Dental care 20%
  • Treatment 56%
  • Prevention 20% .

In their systematic review, the researchers found that almost twice as many people receiving amoxicillin had diarrhea compared with participants receiving placebo. Diarrhea was more than three times as likely among participants receiving amoxicillin-clavulanate. An association was also observed between candidiasis and amoxicillin-clavulanic acid use.

However, the number of reported harms were fewer than the authors expected, following clinical anecdotal experience and observationally derived data. These sources had previously reported rashes and gastrointestinal disturbances as common harms.

Harms were deemed to be poorly reported, leading the authors to conclude that their true incidence could be higher. Only 25 of the studies assessed included information on harms, which led us to suspect that their authors simply did not collect such information or, if they did, failed to publish it, write the authors.
