What is meant by dental carries? How are they caused?

Question

Answer

Tooth decay, also known as dental caries or cavities, is a breakdown of teeth due to acids made by bacteria. Symptoms may include pain and difficulty with eating. Dental caries is caused by the action of acids on the enamel surface. The acid is produced when sugars (mainly sucrose) in foods or drinks react with bacteria present in the dental biofilm (plaque) on the tooth surface.

Answer

Tooth decaying also called as dental carries , mean breakdown of teeth .
It is caused by the bacteria present in mouth which break down the sugar to form acids .
Tooth decay starts when the pH of acid formed in the mouth falls down .

Dental Caries: Causes and Prevention

Dental caries, commonly known as tooth decay or cavities, is a prevalent oral health issue that affects people of all ages. It occurs when the hard tissues of the teeth, including the enamel, dentin, and cementum, are progressively destroyed by acid produced by oral bacteria. Dental caries can lead to pain, infection, and even tooth loss if left untreated.

Causes of Dental Caries:

1. Bacterial Plaque: Dental caries is primarily caused by the presence of bacterial plaque, a sticky film that forms on the teeth. Plaque consists of bacteria, food particles, and saliva. The bacteria in the plaque metabolize sugars and produce acids that attack the tooth enamel, leading to demineralization and the formation of cavities.

2. Sugar and Diet: The consumption of sugary foods and beverages, such as candies, sodas, and sweets, contributes significantly to the development of dental caries. The bacteria in plaque use sugar as a fuel source to produce acid, which erodes the tooth enamel. Frequent snacking or sipping sugary drinks throughout the day increases the risk of tooth decay.

3. Poor Oral Hygiene: Inadequate oral hygiene practices, such as infrequent brushing and flossing, can result in the accumulation of plaque on the teeth. When plaque is not removed regularly, it hardens into tartar, which provides a more favorable environment for bacteria to thrive and cause dental caries.

4. Weak Enamel: Some individuals naturally have weaker tooth enamel, which makes them more susceptible to dental caries. Enamel acts as a protective layer for the teeth, and its strength can be affected by genetics, nutritional deficiencies, and certain medical conditions.

5. Dry Mouth: Saliva plays a crucial role in maintaining oral health by neutralizing acids and washing away food particles and bacteria. A decrease in saliva production, also known as dry mouth or xerostomia, can increase the risk of dental caries as there is less protection against acid attacks.

Prevention of Dental Caries:

1. Brushing and Flossing: Regular brushing with fluoride toothpaste and flossing help remove plaque and food particles, minimizing the risk of dental caries. It is recommended to brush at least twice a day and floss daily.

2. Fluoride: Fluoride helps strengthen the tooth enamel and makes it more resistant to acid attacks. Using fluoride toothpaste, drinking fluoridated water, and receiving professional fluoride treatments can help prevent dental caries.

3. Healthy Diet: Limiting the consumption of sugary and acidic foods and beverages can reduce the risk of dental caries. Opting for tooth-friendly snacks like fruits and vegetables and drinking water instead of sugary drinks is beneficial.

4. Dental Check-ups: Regular dental check-ups allow for early detection and treatment of dental caries. Dentists can perform professional cleanings, apply dental sealants, and provide preventive treatments like fluoride varnishes.

5. Saliva Stimulation: If experiencing dry mouth, stimulating saliva flow through sugar-free gum or lozenges, staying hydrated,
