Lack of which may cause tooth cavity and tooth decay, and who doesn’t know the pain of an aching tooth? Perhaps we all have to experience tooth pain at least once in our life-span.

So, oral care is just as important as doing a regular physical check-up. It’s not about bright white teeth. It’s all about overall oral care that covers tooth decay formation of the tooth cavity, germ care of the individuals.

But as all the problems have a solution, many unique home remedies can prevent severe tooth decay and cavity formation.

Tooth decay is the destruction of the tooth, and it starts with the softening of tooth enamel. Tooth enamel is a hard protective guard like a layer of the teeth, and it is the hardest mineral found in our body.

However, acids from particular food and drinks, significantly those high in sugar in carbohydrates, can damage this layer. Tooth decay is a slow process that quite silently, and we ignore it until we feel any pain.

Here are a Few Facts

  • Severe Tooth decay occurred when the leftover food particles started to get deposited in between teeth.
  • Lack of proper brushing and flossing helps the food particles to trap between teeth for long days.
  • The bacterium that lives inside the mouth digests food like bread, candy, milk, cakes, and fruits, etc., and turns them into acid.
  • The bacteria, acid, food particles, and saliva combine to form plaque, a bacterium filled with a sticky film. It aids in tooth decay and gum diseases.
  • The damage of tooth structure happened when the plaque bacteria break down the sugar inside the mouth.
  • If this damaged enamel remains untreated, a cavity inside the tooth developed, and slowly it takes an oversized shape and destroys the whole tooth.
  • Usually, the plaque bacteria attack the inner layer of the tooth, which is known as dentin, and creates cavities in the tooth’s root. This is a root cavity that can make you feel pain when you eat or drink something. 

Causes of Tooth Decay

Some common causes of tooth decay and cavities are

1. Food Habit

Our food habit is the root of many health problems, and tooth decay is not an exception. Some food is used to cling to the teeth and form a layer. Such food includes bread, all types of sugar candy, honey, cereals, milk, etc.

These starchy and sweet food particles remain inside the teeth even after brushing and aids in plaque formation.

2. Lack of Proper Oral Hygiene

Brushing teeth twice a day is the best way to maintain oral neatness. Lack of adequate brushing allows plaque to build up and destroy the tooth coating.

It is always better to brush after eating any sweet food or drink.

3. Plaque Build-up

The residue of food particles, the acid in the mouth, bacteria, and saliva combine to build up a sticky layer that gets harder with time. It contains bacteria that cause severe tooth decay.

When we eat anything, the bacteria inside the plaque use the food’s sugar to produce acid that destroys the tooth enamel and creates a hole after several attacks.

4. Chronic Health Problem

Any chronic health problem may contribute to tooth decay and cavities.

For example, an individual with a chronic liver disorder or indigestion problem has a chance to develop tooth cavities. In those cases, the acid could not flow back to the stomach, slowly affecting the protective shield or tooth enamel.

As a result, tooth erosion begins. Besides, this specific eating disorder or Bulimia Nervosa can cause tooth erosion and decay.

5. Dry Mouth or Xerostomia

When the salivary gland makes insufficient saliva, a plaque build-up more quickly as saliva helps wash the plaque naturally.

So, dry mouth is another Reason for plaque formation and severe tooth decay.

6. Due To Receding Gums

When the gums that hold the tooth recede, gaps form in between the gum and tooth line, which allows the diseases causing bacteria to develop.

If this condition continues, the bacteria damage the surrounding tissue and bone structure of the tooth, resulting in tooth decay and tooth loss.
