Mouth Tasting Like Plastic? Here's Why

why does my mouth taste like plastic

A plastic taste in the mouth is unusual and could be a sign of an underlying dental or medical problem. The most common cause of a bad taste in the mouth is poor dental hygiene, but this usually presents as a metallic taste. Other causes of a metallic taste in the mouth include food allergies, vitamin supplements, medication, and serious illnesses such as kidney or liver problems, undiagnosed diabetes, or certain cancers. If you are experiencing an unusual taste in your mouth that is not metallic, it is important to consult a medical professional for advice and treatment.

Poor dental hygiene

While a plastic taste in the mouth is not specifically addressed in the sources, a bad taste in the mouth and bad breath (halitosis) are commonly associated with poor oral hygiene.

To improve oral hygiene, it is recommended to brush twice a day with fluoride toothpaste and floss at least once a day to remove food debris and plaque. Tongue cleaning is also important, as bacteria and food debris can accumulate on the tongue, contributing to bad breath. Dentists also recommend regular dental cleanings and the use of bacteria-killing mouthwashes to address bad breath caused by poor oral hygiene.

In addition to poor oral hygiene, other factors that can contribute to bad breath include dry mouth, acid reflux, smoking, and certain health conditions. Dehydration, for example, can lead to a decrease in saliva production, which helps rinse out the mouth and reduce bacterial growth. Therefore, staying hydrated and avoiding substances that can dry out the mouth, such as alcohol, caffeine, and tobacco products, can also help improve oral hygiene and reduce bad breath.

Medication side effects

While a plastic taste in the mouth is not a common side effect of medication, a metallic taste in the mouth is. This taste is often caused by medication for gastrointestinal issues, such as acid reflux, or gastroesophageal reflux disease (GERD). Antibiotics, antihistamines, antidepressants, and angiotensin-converting enzyme (ACE) inhibitors are also known to cause a metallic taste in the mouth.

Supplements, especially in high doses, can also leave a metallic taste in your mouth, especially if they contain chromium, copper, or zinc. Prenatal vitamins, iron, and calcium supplements are also common culprits. This taste should go away soon after you take the pills.

If you are experiencing a metallic taste in the mouth due to medication side effects, there are some steps you can take to alleviate the issue. Firstly, drinking plenty of fluids and staying well-hydrated can help. Additionally, chewing sugar-free gum, preparing foods with spices to add flavor, and brushing or scraping your tongue and teeth regularly are recommended.

It is important to note that medication side effects very rarely cause permanent taste changes. If you experience any concerning side effects, it is always best to consult your healthcare provider.

Food allergies

A metallic taste in the mouth is a common phenomenon that can occur due to various reasons, including food allergies. While it is typically not a cause for concern, it may sometimes indicate an underlying health issue.

Allergies to specific foods, such as shellfish or tree nuts, are known to cause this metallic taste. If you experience this taste after consuming certain foods, it is important to identify and avoid those triggers. Keeping a food diary and noting any reactions can help pinpoint specific allergens.

Additionally, some people may experience a temporary condition called "pine nut syndrome" or "pine mouth," which is characterised by a metallic taste that occurs after consuming pine nuts. This sensation usually resolves on its own within a few days to a week.

Other Causes

Apart from food allergies, several other factors can contribute to a metallic taste in the mouth:

  • Medications: Many medications, including allergy medications, antibiotics, antidepressants, and chemotherapy drugs, can interfere with taste receptors, leading to a metallic taste.
  • Hormonal Changes: Hormonal fluctuations during pregnancy can cause disturbances in taste and smell, resulting in a metallic taste. This is more common during the first trimester.
  • Oral Health: Poor oral hygiene, gum disease, mouth injuries, oral surgery, and dental prostheses can all impact your sense of taste and contribute to a metallic taste.
  • Smoking: Tobacco use can alter your sense of taste and contribute to dysgeusia. Quitting smoking may help alleviate this issue.
  • Nutrient Deficiencies: Deficiencies in certain nutrients, such as zinc and vitamin D, may be linked to changes in taste, including a metallic taste in the mouth.
  • Sinus Issues: Sinus problems, including infections and blockages, can impair your sense of taste and contribute to a metallic taste.
  • Gastrointestinal Issues: Conditions like acid reflux or gastroesophageal reflux disease (GERD) can cause stomach acid to enter the mouth, affecting taste receptors and leading to a metallic taste.
  • Ageing: As we age, our taste buds naturally diminish, and certain health conditions, such as dementia, can expedite these changes, making food taste different.

Sinus issues

A plastic taste in the mouth can be caused by sinus issues. Sinus infections, or sinusitis, can cause post-nasal drip, which can lead to a bad taste in the mouth.

The sense of taste is closely linked to the sense of smell. When your sinuses are blocked or infected, your sense of smell is affected, which in turn impacts your sense of taste. Sinus issues can also cause a metallic taste in the mouth. This should go away once the sinus issue is resolved.

If you are experiencing a bad taste in your mouth, it could be due to poor dental hygiene, oral thrush, or gum disease. It could also be caused by something you have eaten, or other health conditions, including vitamin deficiencies, neurological issues, or gastrointestinal problems.

If you are concerned about a persistent bad taste in your mouth, you should consult a healthcare professional or dentist to determine the underlying cause.

Oral thrush

While a plastic taste in the mouth is not a medically recognised symptom, there are several causes of a bad taste in the mouth, including oral thrush.

Common signs of oral thrush include a white coating in your mouth and throat, a fuzzy or cottony feeling in your mouth, and a change in your sense of taste. It can also cause pain or a burning or tingling sensation in your mouth, making it difficult to eat and drink. Severe oral thrush can affect your ability to swallow or speak.

If you suspect you have oral thrush, it is important to see your doctor or dentist. They may take a sample of the coating in your mouth using a sterilised cotton swab and test it in a laboratory. Oral thrush can be treated with antifungal drugs called antimycotics, which can be applied directly to the affected areas in the mouth or swallowed. These medications are typically used for about one to two weeks.

To prevent oral thrush, it is important to maintain good oral hygiene by regularly brushing, flossing, and rinsing your mouth. It is also recommended to limit your intake of sugar, as yeast feeds on it.
