Dry mouth is a condition where the mouth does not produce enough saliva. Many report experiencing it during or after a COVID-19 infection. This lingering effect can cause discomfort, impacting daily activities like speaking and eating. This article guides understanding and managing post-COVID dry mouth.
Understanding Post-COVID Dry Mouth
Dry mouth after a COVID-19 infection can arise from several factors. The SARS-CoV-2 virus directly affects salivary glands, which contain ACE2 receptors that the virus uses to enter cells. When the virus binds to these receptors, it can decrease saliva production, contributing to dryness. Additionally, general illness with fever can lead to dehydration, further reducing salivary flow.
Medications used during recovery from illness may also have dry mouth as a side effect. Changes in the body’s immune response following infection could also play a role in altering salivary gland function. Individuals experiencing post-COVID dry mouth often report a sticky feeling in their mouth, difficulty speaking or swallowing, and sometimes an altered sense of taste.
Immediate Relief Strategies
Addressing post-COVID dry mouth often begins with simple home strategies. Staying well-hydrated is key; sip water frequently throughout the day to lubricate the mouth. Avoid beverages that can contribute to dehydration, such as those containing caffeine and alcohol.
Stimulating natural saliva flow can provide relief; chew sugar-free gum or suck on sugar-free candies. Avoid irritating foods like those that are spicy, salty, or acidic to prevent discomfort to dry oral tissues. Using a humidifier, especially in the bedroom at night, can add moisture to the air and help keep the mouth from drying out during sleep. Maintaining good oral hygiene, including regular brushing and flossing, is important to prevent complications from reduced saliva.
Targeted Over-the-Counter Solutions
When lifestyle adjustments are not sufficient, various over-the-counter products can provide more direct relief. Artificial saliva products, such as oral moisturizers, sprays, and gels, can temporarily supplement natural saliva. Brands like Biotene, Mouth Kote, Oasis, and XyliMelts offer these solutions.
Specialized toothpastes and mouthwashes also help. Choose alcohol-free mouthwashes, as alcohol can further dry out the mouth. Many products contain ingredients like xylitol or glycerin, which moisturize and stimulate saliva production. Lozenges can also provide comfort and stimulate salivary glands when dissolved in the mouth.
When to Consult a Healthcare Professional
While many cases of post-COVID dry mouth improve with home care and over-the-counter remedies, you should consult a healthcare professional in some instances. Seek medical advice if symptoms persist or worsen despite self-care measures. Severe discomfort, significant difficulty eating or speaking, or signs of oral infections also warrant a visit.
Dry mouth can increase the risk of oral thrush, a fungal infection appearing as creamy white lesions. If you observe such lesions, soreness, or a cottony feeling, consult a doctor. A healthcare professional can rule out other underlying conditions or discuss prescription treatment options.
