Dry mouth, also known as xerostomia, is more common than most people realise. It might be not only a slight pain in its essence but also indicate a health complication, say dentists. It occurs as a result of the inability of the salivary glands in your mouth to produce just enough saliva to keep your mouth moist. Salivation is important in the preservation of oral health, and the absence of salivation may cause a number of dental and health issues.

What Is Dry Mouth?

Dry mouth refers to a condition that experiences an abnormally dry mouth because of lack of sufficient saliva. Saliva assists in cleaning the food particles as well as neutralising acids and bacteria. The mouth is susceptible to infections, cavities, and even bad breath when the level of saliva reduces.

This condition is either a temporary one, as may happen upon intake of some drugs, or it may be chronic, as may be associated with health complications or interventions.

Dry Mouth: Symptoms to Watch Out For

Dry mouth is hard to miss, in the event that you are aware of it. The common symptoms include:

  1. Slick or dry mouth and throat.
  2. Frequent thirst
  3. Cracked lips or mouth sores
  4. Problem with swallowing, difficulty speaking, difficulty chewing.
  5. Bad breath
  6. Dry or burning tongue

In case of these symptoms taking more than a few days, then it is worthy of visiting a dentist in order to have an evaluation.

How Dry Mouth Affects Oral Health?

There is always a shortage of saliva, which can cause severe problems with the mouth. Saliva plays key roles in the cleaning of food in the mouth and breaking down the acids that are produced by the bacteria. Lack of sufficient amounts of it leads to a higher rate of accumulated plaque that puts individuals at risk of tooth decay, gum disease and mouth infections. In extreme cases, it may also contribute to taste as well as render the use of dentures painful.

Home Remedies to Treat Dry Mouth

  1. Hydration is must. Consume plenty of water throughout the day.
  2. Chewing sugar-free gum can stimulates the flow of saliva.
  3. Say NO to alcohol and tobacco as they can cause dryness.
  4. To avoid dryness, you can use saliva substitutes like mouth sprays or gels.
  5. Brush, floss, and use fluoride toothpaste twice a day for good oral health.

When to See a Dentist?

See your dentist in case you always feel dry or you eat and speak with difficulty. Chronic dry mouth can be an indication of some underlying condition that requires medical intervention. One can avoid cavities by taking care of their mouth at an early age.

TRENDING NOW

Dry mouth might appear to be a minor takeaway, yet dentists say that this symptom should not be overlooked at all. The mouth requires a healthy flow of saliva; hence, one should listen to what the body is telling you.
