Dry mouth, also known as xerostomia, is a common condition that affects millions of people. Dry mouth results when the salivary glands produce insufficient saliva. It can make speaking, chewing, and even swallowing complicated. In some cases, bad breath and difficulty sleeping can also result from it. Thus, it is important to get it checked and treated as soon as possible. If you have a persistent dry mouth in the morning or throughout the day, read on to know what dry mouth treatment options you have.
Common Causes of Dry Mouth
Here are the common causes of dry mouth you have to know:
- Medicines: Several medications, such as antihistamines and antidepressants, slow down saliva secretion, which results in dry mouth syndrome.
- Ageing: As you grow older, the functioning of the saliva gland declines. This can result in chronic dryness of the mouth.
- Cancer Treatment: Chemotherapy and radiation may harm salivary glands, which causes extreme dry mouth.
- Snoring and Mouth Breathing: Mouth breathing, especially at night, creates a dry mouth during sleep and causes irritation of the throat.
- Tobacco and Alcohol Consumption: Smoking and alcohol lower saliva production and can worsen dry mouth sensation.
Effective Remedies for Dry Mouth Relief
Here are some effective remedies for getting relief from dry mouth:
Stay Hydrated
Daily consumption of plenty of water is one of the easiest and most effective mouth dryness remedies. Water maintains saliva production and avoids dehydration, which is the primary cause of constant dry mouth.
Chewing Sugar-Free Gum
Chewing sugar-free gum improves saliva secretion, which calms the dry mouth sensation. However, you must have to choose sugar-free options, as sugar can contribute to tooth decay. This is an easy and efficient means of dealing with severe dry mouth during the day.
Try Using Humidifiers
A humidifier adds moisture to the air, which relieves the irritation caused by a dry mouth at night during sleep. Dry air indoors has the potential to worsen the symptoms, and thus, having a humidifier in your bedroom could be particularly useful if you keep waking up feeling as though your mouth is so dry that it feels like sandpaper.
Use Saliva Substitutes
Saliva substitutes like mouth sprays or gels can be used to keep the mouth moist. Some OTC dry mouth meds containing xylitol can relieve the condition by acting like natural saliva. Such mouth dryness medication is especially useful for individuals who suffer from chronic dry mouth as a result of drugs or medical conditions. However, try to get a dentist’s approval before taking any drug for dry mouth.
Lifestyle Changes for Managing Dry Mouth
Apart from tablets for dry mouth and home remedies, you can also try some simple lifestyle changes that might just work as a miracle cure for dry mouth if practised with consistency :
Oral Hygiene
You need regular oral hygiene in order to avoid dry mouth syndrome complications. Some general dentistry tips include brushing and flossing your teeth every day to prevent tooth decay and gum disease. You should also use a fluoride toothpaste for brushing and an alcohol-free mouthwash to wash out your mouth.
Breathing Through the Nose
As mentioned earlier, breathing in through the mouth can worsen dry mouth. Hence, train yourself to breathe through your nose, especially at night, to improve dry mouth treatment. If nasal congestion forces you to breathe through your mouth, consider using saline sprays or seeking medical advice.
Herbal Remedies
Certain herbal teas, such as ginger and chamomile, hydrate naturally occurring mouth dryness. In fact, not only do they hydrate, but these teas also contain soothing properties that promote overall oral health.
When to Seek Help for Dry Mouth?
Although some home remedies and lifestyle changes can provide relief, severe dry mouth can be a sign of an underlying condition that requires professional dental care. If your dry mouth feeling gets worse or affects your daily activities such as eating, speaking, or sleeping, it’s time to consult a dentist.
If left untreated, chronic dry mouth can put a person at higher risk of developing cavities, gum disease, and other dental problems. So, schedule an appointment at Complete Smiles to get treated for dry mouth syndrome. They provide comprehensive dental care with advanced treatments and are available all seven days a week.
