The dangers of dry mouth from allergy meds
Written in association with:If you often use allergy medications like antihistamines or decongestants, you might know about dry mouth as a possible side effect. Dr Sulaman Anwar, certified specialist periodontist, explains how antihistamine/decongestant side effects like dry mouth could lead to dental problems.
Side effects of antihistamines and decongestants on oral health
Dr Anwar emphasises that saliva is crucial for a healthy mouth. It helps wash away food bits, neutralises acids made by bacteria, and even aids in teeth repair. However, allergy medications like antihistamines or decongestants can reduce saliva production, making your mouth more vulnerable to harmful bacteria and tooth decay. This can increase the risk of both cavities and gum issues.
Thankfully, there are ways to relieve dry mouth from allergy medications. Dr Anwar recommends staying hydrated by drinking water, chewing gum that's sugar-free, and refraining from alcohol and caffeine. He also recommends using a saliva substitute or a humidifier at home to add moisture.
Dry mouth can be a sign of other health concerns
Furthermore, dry mouth can be a sign of other health problems, especially as you age, according to Dr Safa Al-Naher, the founder of Serene by Dr Safa. While ageing itself doesn't directly cause dry mouth, almost 46% of people over 65 take medications that reduce saliva, leading to dry mouth.
Dry mouth is often a result of medications like those for heart issues, blood pressure, and depression. Your doctor, pharmacist, or dental team can tell you if your meds might cause this. Dry mouth can also come from medical treatments like radiotherapy or head/neck surgeries.
In some cases, medical conditions like diabetes, lupus, sjogren's syndrome, or blocked salivary glands can directly cause dry mouth. Dr Al-Naher adds that dry mouth can even hint at more serious conditions like Parkinson's disease, autoimmune disorders, cancer, or stroke.
Because of these potential concerns, if you have dry mouth, it's wise to consult your dentist or doctor. People with allergies might not realise the impact of antihistamines' and decongestants' side effects on their oral health.
