What will happen if saliva is not secreted?

Saliva plays a crucial role in maintaining oral health and facilitating the initial stages of digestion. Its absence or reduced secretion can lead to various negative consequences. Here is a detailed explanation of what happens if saliva is not secreted:

1. Impaired digestion: Saliva contains enzymes, such as amylase, which initiate the breakdown of carbohydrates in the mouth. Without saliva, the process of digestion becomes less efficient, leading to difficulty in swallowing and a reduced ability to break down food.

2. Dry mouth (xerostomia): The lack of saliva secretion results in a dry mouth, causing discomfort and difficulty in speaking, chewing, and swallowing. This condition can also lead to a constant parched feeling, cracked lips, and a decreased sense of taste.

3. Tooth decay and cavities: Saliva acts as a protective barrier for teeth by neutralizing acids produced by bacteria and washing away food particles. Without saliva, the oral cavity becomes more acidic, promoting the growth of harmful bacteria and increasing the risk of tooth decay and cavities.

4. Gum disease: Saliva contains antimicrobial properties that help prevent the overgrowth of bacteria in the oral cavity. Without saliva, the risk of gum disease, such as gingivitis and periodontitis, increases significantly.

5. Halitosis (bad breath): Saliva helps cleanse the mouth by removing food debris and bacteria. Without sufficient saliva, these particles remain in the mouth, leading to the development of bad breath.

6. Difficulty in wearing dentures: Saliva acts as a lubricant, allowing dentures to fit comfortably and reducing friction between the denture and oral tissues. Without saliva, wearing dentures can become extremely uncomfortable and even painful.

7. Speech difficulties: Saliva aids in the formation of sounds during speech. In the absence of saliva, speaking clearly becomes challenging, resulting in slurred or unclear speech.

8. Increased risk of oral infections: Saliva contains antibodies and proteins that help fight against infections. A decrease in saliva production weakens the body's natural defense mechanisms, making the oral cavity more susceptible to infections.

9. Reduced overall oral health: Without saliva, the oral environment becomes imbalanced, leading to a cascade of oral health problems, including tooth sensitivity, dry and cracked lips, and an increased risk of oral ulcers.

In summary, the absence or reduced secretion of saliva can have significant negative impacts on oral health, digestion, and overall well-being. It is important to address any issues related to saliva production and seek appropriate medical or dental advice to mitigate these effects.

If saliva is not secreted then digestion of food doesnt take in a proper way especially carbohydrates......saliva secret an enzyme called salivary amylase or ptyalin which helps in the digestion of carbohydrates
if u have cold and cough ...u feel tired and u avoid to eat
