Why does tooth decay start when pH of mouth is lower than 5.5.?

Question

Answer

Because our teeth are made up of calcium and it is corroded because of acidic nature

Answer

Because it become strong acid and acids are corrosive in nature

Answer

Tooth decay  start when pH is lower than 5.5 this is because when pH is lower than 7 it indicates the acid and the pH of lower than 5.5 it indicates the acid is strong and  enough to attack the enamel of our teeth and corrode it.

Answer

When the ph in the mouth fells below 5.5, tooth decay start. Bacteria present in our mouth break down the sugar to  produce acid. this is because the acid is strong Enough to attack the enamel of our teeth and corrode it. this start the tooth decay.

Answer

The tooth decay start when the pH of mouth below 5.5 because the enamel which is the hardest substance in the start to decay.

Answer

Our teeth is made up of calcium phosphate,hardest substance in our bodybut due to excessive take of sweets and chocolates it starts corroses and tooth decay starts when the pH of teeth is less than 5.5

Answer

Why Tooth Decay Starts at pH Lower than 5.5
Tooth decay, also known as dental caries, is a common dental problem that occurs when acids produced by bacteria in the mouth erode the enamel of the teeth. This process can be accelerated when the pH of the mouth drops below 5.5, creating an acidic environment that is conducive to the growth of harmful bacteria.

Acid Attack on Enamel
- When the pH of the mouth drops below 5.5, it indicates an acidic environment.
- Acids produced by bacteria in the mouth can attack the enamel of the teeth, which is the hard outer layer that protects the inner layers of the tooth.

Demineralization of Enamel
- The acids produced by bacteria can lead to demineralization of the enamel.
- Demineralization occurs when minerals such as calcium and phosphate are leached from the enamel, weakening its structure.

Bacterial Growth
- Acids in the mouth can promote the growth of harmful bacteria that feed on sugars and produce more acids.
- These bacteria form a sticky film called plaque, which can further contribute to the erosion of the enamel.

Cavity Formation
- As the enamel is weakened and demineralized, it becomes more susceptible to cavities.
- If left untreated, cavities can progress to affect the deeper layers of the tooth, leading to pain and potential tooth loss.

Prevention
- Maintaining a neutral pH in the mouth (around 7) through proper oral hygiene practices can help prevent tooth decay.
- This includes brushing and flossing regularly, limiting sugary and acidic foods, and visiting the dentist for regular check-ups and cleanings.
In conclusion, tooth decay starts when the pH of the mouth drops below 5.5, creating an acidic environment that promotes the erosion of enamel by harmful bacteria. By understanding the role of pH in dental health and taking preventive measures, individuals can protect their teeth from decay and maintain good oral hygiene.

Why does tooth decay start when the pH of mouth is lower than 5.5?

Tooth decay occurs when pH of mouth is below

Assertion : If the pH inside the mouth decreases below5.5, the decay of tooth enamel begins.Reason : The bacteria present in the mouth degrades the sugar and left over food particles and produce acids that remain in the mouth after eating.
