You need to pamper your teeth a lot because they are very prone to cavities and decay when left uncared for long. But how long does it take for a cavity to form?

Common Causes Of cavities In Children:

Absence Of Brushing

Some mothers think that brushing is only meant for adults and their kids don’t need it unless and until they attain their permanent teeth. Following this myth is the prime cause of cavities in children which later progresses excessively. Kids as small as 2 years are recommended to start brushing within parental supervision. A pea-sized toothpaste can be applied on their toothbrush before brushing and they are good to go!

Leaving A Feeding Bottle For Overnight

A couple of children are habitual of keeping a feeding bottle in their mouth for the whole night. Milk consists of added sugar that can make teeth very attractive for bacteria to feed on their surface. Hence the chances of the cavitation are raised to a higher extent.

Unnecessary Junk Munching

Let’s not just blame kids for that, even adults cannot stop munching. The extra added sugars in confectionaries facilitate bacteria to resistant to the tooth surfaces. As a result, leading to tooth decay and cavities.

Common Causes Of A Cavity In Adults

Negligence Towards Oral Hygiene

Dental studies and researches have inferred that around 80% of tooth decay in adults is in response to maintaining proper oral hygiene. It is surprising to say that some adults are not even familiar with the use of mouthwashes and brushing techniques. Bacteria tend to be most active during the night and not brushing teeth before bed is a stroke of wonderful luck to them.

Systemic Diseases

There are certain diseases that make a patient vulnerable to cavities. This is because some systemic conditions can lower the pH of the oral environment which is one of the most favorable conditions in which a cavity-forming bacteria can survive. The diseases which can assist in cavities are Diabetes, Mellitus, Acidity, GERD (gastroesophageal reflux disease), and calcium deficiency.

How Much Time Does It Take For A Cavity To Form?

A cavity does not just forms in a day or two. It is not possible for you to wake up in the morning and just notice a big hole! The time required for a cavity to form depends on a number of factors.

1.  pH: The lower the pH the acidic the environment of the oral cavity will be. In this case, it will probably take less than a month for the cavity to start forming up.

2.   Age: the porosity of the tooth depends on the age of the patient. Small children have more pores in their teeth which makes them brittle. This, in turn, speeds up the rate of reaction. Hence requires less time. When a person reaches adulthood, he/she becomes more concerned about their looks and by this time they have sound knowledge regarding how to take care of their oral hygiene.

Therefore during this period, a delay in cavity occurs. In contrast, older age patients require less time to develop cavities because of systemic conditions. This answers the question of most patients who ask how long it would take for a cavity to form.

Dietary Habits

Patients who consume high sugar diet tend to get their cavitation process speeded up. A normal black spot takes about a whole year to progress into cavitation. However, sugary diet aids cavitation and the 1 year time duration reduces to 6 months.

What Is The Fate Of A Cavity?

You all must be wondering about what happens after a cavity is formed? Well, a cavity can cause big havoc in your mouth and will probably be unnoticed. It transforms into your root canals and then down into the nerves. This can trigger pain, swelling and at times fever.

Furthermore, for those questioning about how long does it takes for a cavity to reach the nerves, it is clear that as soon as the cavity proceeds into root canal it takes no time to reach the nerves.
