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

Tooth decay starts when the pH of the mouth is lower than 5.5. Tooth enamel, made of calcium phosphate is the hardest substance in the body. It does not dissolve in water, but is corroded when the pH in the mouth is below 5.5. Bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth. Preventions : 1. Clean the mouth after eating food. 2. Using tooth pastes, which are generally basic neutralize the excess acid and prevent tooth decay.

The correct answer is 5.5. • Tooth decay starts when the pH of the mouth is less than 5.5. Additional Information • the pH scale is used to specify how acidic or basic the solution is. If the pH value of the solution is less than 7, it is acidic. If the pH value is more than 7, it is basic. • In the given case, if the pH of the mouth gets less than 5.5, it means that our mouth is very acidic. • The acid in our mouth has started to attack the enamel of our teeth and has started to corrode it. The sugar and food particles that get stuck in teeth are degraded by Bacteria and acid is produced as a result. • Please note that the enamel of teeth is made up of calcium phosphate which is the hardest substance in the body. • Saliva has a pH normal range of 6.2-7.6. • The normal resting pH of the mouth does not fall below 6.3.

The correct answer is 5.5. Key Points • Tooth decay starts when the pH of the mouth is lower than 5.5. • Tooth enamel, made up of calcium phosphateis the hardest substance in the body. • It does not dissolve in water but is corroded when the pH in the mouth is below 5.5. • Bacteria present in the mouth produce acids by the degradation of sugar and food particles remaining in the mouth after eating. • The best way to prevent this is to clean the mouth after eating food. • At the pHof 5.5, the teeth risk of cavities and tooth decay begins in the mouth. Additional Information • The role of toothpaste to prevent tooth decay is as follows- • A healthy mouth is in a neutral pH range. Teeth can actually become stronger and re-mineralize when the pH of the mouth is 7.5 or above. • Bacteria present in the mouth produce acids by the degradation of sugar and food particles remaining in the mouth after eating. • Using toothpaste, which is generally basic, for cleaning the teeth can neutralize the excess acid and prevent tooth decay. • Fluoride is a mineral that can prevent tooth decay from progressing. It can even reverse or stop, early tooth decay. Hence most of the toothpastes have fluoride ions. • Also, tooth-pastes have salts in them which decreases the acidity of mouth.

It’s common knowledge that sugar is bad for your teeth, but it wasn’t always so. In fact, when the ancient Greek philosopher Aristotle first observed that sweet foods like soft figs caused tooth decay, nobody believed him. But as science has progressed, one thing is certain — sugar causes tooth decay. That said, This article takes a detailed look at how sugar affects your teeth and how you can prevent tooth decay. Many different types of bacteria live in your mouth. Some are beneficial to your dental health, but others are harmful. For example, studies have shown that a select group of harmful bacteria produce acid in your mouth whenever they encounter and digest sugar ( These acids remove minerals from the tooth enamel, which is the shiny, protective, outer layer of your tooth. This process is called demineralization. The good news is that your saliva helps to constantly reverse this damage in a natural process called remineralization. The minerals in your saliva, such as However, the repeated cycle of acid attacks causes mineral loss in the enamel. Over time, this weakens and destroys the enamel, forming a cavity. Simply put, a cavity is a hole in the tooth caused by tooth decay. It’s the result of harmful bacteria digesting the sugar in foods and producing acids. If left untreated, the cavity can spread into the deeper layers of the tooth, causing pain and possible tooth loss. The signs of tooth decay include a toothache, pain when chewing and sensitivity to sweet, hot ...
