4 Signs of Toothpaste Allergy

18 July 2016 by Lillian Dixon

Toothpaste contains a lot more than fluoride. While it is not widely known, some ingredients may trigger an allergic reaction. It is often flavourings which are added to toothpaste such as mint, menthol or cinnamon which trigger allergic reactions rather than compounds which clean the teeth. Below is a brief guide to the signs of symptoms of toothpaste allergy which will help you to identify if you are suffering from the problem.

Itchy skin surrounding your mouth 

This is a symptom which is often ignored because it doesn't create cosmetic problems or cause pain. However, if after brushing you notice itchiness of the skin which surrounds your mouth, it is highly likely that you are having an allergic reaction to the toothpaste. The itchiness can also affect your lips, tongue and the roof of your mouth. Although it might start as a slight annoyance, over time the condition can worsen and cause inflammation. 

Cracking or dryness around your mouth

If you notice any cracking or dryness around your mouth, this could be a sign of a toothpaste allergy. This symptom is called cheilitis. If left untreated, this condition can lead to the formation of pus within the cracks around your mouth. Although this condition can be extremely unpleasant, it will generally clear up once you cease exposure to the allergen responsible. 

Upset stomach

Most people know that it is not a good idea to swallow toothpaste, but it is inevitable that a small amount will be swallowed and enter your stomach during brushing. If you are allergic to toothpaste, it is possible that this will cause you to experience an upset stomach, leading to vomiting, diarrhoea and nausea. This problem will quickly pass once you stop using the toothpaste which is causing the problem.

Sensitivity and swelling of your mouth

While there are a number of dental conditions which can cause sensitivity and swelling of the mouth, if you have a toothpaste allergy, you may notice that your gums become more sensitive and oral tissues such as your tongue and cheek lining may begin to swell. If these conditions suddenly begin when you try a new toothpaste, you should switch back to your old brand.

If you have any concerns about your dental health or possible allergies, you should book an appointment with a dentist who will be able to assess your oral health and refer you for any necessary treatment.
