Why do your teeth become cavity-prone?

Dental decay, caries, and cavities all mean the same thing. It is a result of the bacterial attack on your teeth, which compromises their structure, eventually resulting in loss if left untreated. Unlike most other body parts, the teeth, much like the nervous system, lack the ability to auto-repair and need external intervention. Yes! The tooth cannot heal itself. Nor do only medications help treat dental diseases. dental diseases need treatments and maintenance.

The most common reason for cavities is the lack of a good oral hygiene regimen however, several other factors such as diet, genetics, physiology of the saliva, and pre-existing conditions also play a vital role in causing cavities.

What does being cavity-prone mean?

What does the term “cavity prone” mean? This means you are one of those who have decay in their teeth more than others. Usually, when you visit a dentist you always, unfortunately, find out that they have a cavity—sometimes even multiple cavities.

When 3 more than 3 teeth in your mouth are affected by cavities your mouth becomes cavity prone. Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny openings or holes. At times cavities may be visible and at times or they may be hidden between two teeth. Cavities, also called tooth decay or caries, are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks, and not cleaning your teeth well.

Types of cavities

The tooth is a unique structure where every surface is prone to decay to a varying degree. Depending on the surface under bacterial attack, the consequences also vary. The easiest way to understand this is by understanding the layers of teeth.

Infection involving the upper enamel

Enamel is the outermost layer of the tooth and the most resilient one as well. Intercepting decay at this level is the most ideal situation. Your dentist will simply drill out the decayed portion and replace it with a similar colored resin-based material.

Infection involving upper enamel and inner dentin

The second layer of the tooth i.e. The dentin is not strong as the enamel and decay spread through it rather rapidly in comparison. If intercepted in time, it can be preserved well by drilling out the decayed portions and replacing them with the resin-based material. However, if overlooked, it’s only a matter of time before the decay reaches the core of the tooth, which is known as the pulp.

Infection involving Pulp

Pulp is a network of blood vessels and nerve plexus that provide the tooth it’s vitality. Once infected, the only solution is to remove all of it and disinfect it from within. The process is known as root canal treatment.

Infection affecting surrounding structures:

Decay can not only affect the teeth but its surrounding structures. The bone and gums suffer in the process of neglection. The extent of infection in the bone determines whether the teeth are salvageable or not.

Infection causing life-threatening conditions: 

Although rare, long-standing infections of the teeth spread to different parts of the head and neck known as “spaces”. Multiple factors such as compromised immune system, pre-existing conditions, etc. Contribute to the likelihood of space infections.

What causes you to be cavity-prone?

Hidden cavities between your teeth

Habits –

Excess consumption of sugary and sticky foods

A diet rich in carbohydrates makes you prone to tooth cavities. This is because the bad bacteria feed on the sugars and release acids that dissolve your enamel and cause cavities.

Failing to brush twice

Improper plaque removal from your mouth can cause teeth cavities as most of the bad bacteria reside in the plaque colonies.

Brushing anyhow and haphazard

Not brushing the right way can leave some plaque remnants behind and can onset the process of cavities.

Ignoring flossing your teeth

Flossing helps remove the bacteria and food between your teeth. Failing to floss can give rise to hidden cavities between two teeth.

Improper tongue cleaning

Most of the bad bacteria remain on your tongue. Failing to scrape your tongue can leave the bacteria in the mouth and can give rise to cavities.

Plaque and calculus buildup on teeth and gums

This is the main reason why you develop cavities in your teeth as most of the bacteria reside in the plaque colonies and calculus layer.

Food locked between your teeth

Failing to get your teeth cleaned every 6 months can cause the food to remain locked between your teeth giving rise to hidden cavities.

Food remains in the mouth for a long time

Food that remains in contact with your teeth for a long time gives enough time for the bacteria to release acids and dissolve the enamel to cause cavities.

Frequent snacking and a diet rich in carbohydrates

Not only the time but also the frequency of carbohydrate intake matters where cavities are concerned.

Excess consumption of acidic and sugary drinks

Acidic contents in the acidic juices and beverages make your teeth more prone to tooth erosion causing thinning of enamel and more susceptible to cavities.

Mouth breathing

breathing through your mouth can cause dry mouth and insufficient flow of saliva can make your teeth more prone to cavities.


smoking calls in for dry mouth, which again makes you more prone to cavities.


Some people are more prone to cavities due to genetics and poor enamel quality. Weak enamel makes your teeth more prone to cavities.
