Cause Of Cavities

In this section, we are going to dive into the topic “Cause of cavities”. Following are the most common things which can cause a cavity in your mouth. Some of these causes are even a part of our daily life. So, try to avoid them as much as you can.


Poor oral hygiene can increase the amount of plaque in your mouth. Plaque is a sticky substance that attaches to our teeth and causes the development of cavities. Plaque generally consists of bacteria, food particles, and acid etcetera. We cannot stop the production of bacteria in our mouth neither we can completely get rid of food particles and acid. That is why cavities are a very common health problem. To decline the number of bacteria and food particles, following are regular oral hygiene is very important.


As we discussed earlier that cavities are not only the result of sugary food but there are tons of other causes of the development of cavities. Genetics is one of them. It would be a surprise for you that around 60% of the cavities are the result of genetic factors. If your body contains a gene G20A, you are five times more likely to get cavities from others.


Age is another common factor that plays role in the development of cavities. Old people are more likely to develop cavities than young people. A research proved that the risk of cavities increases after the age of 65. But you should not worry about it as age is just a number and you cannot stop aging. So, a better solution will be to visit your dentist now and then and also take care of your oral hygiene.

Brushing too much:

You may familiar with a quote that too much of a good thing is a bad thing. Although, brushing is very beneficial for the health of your teeth but crossing the limits will give you nothing but loss. Brushing your teeth once a day is normal and brushing twice a day is also acceptable but if you brush more than that, then your tendency of developing cavities will increase.


No doubt that most of the cavities are the result of your dietary habits. Eating or drinking things that contain sugar in large amounts can increase the production of acid in your mouth. The bacteria present in your mouth converts the sugars into acid and because of this acid, plaque starts to develop on your teeth. We already know that how dangerous plaque is for our teeth. This plaque causes the formation of cavities.

Prevention From Cavities

You may be familiar with the proverb that prevention is better than cure. In this section, we are going to discuss some tips which you could try to prevent cavities.

Brush your teeth:

Brushing your teeth on daily basis can hugely decline the chances of development of cavities. This is the first and most important thing you should consider doing even before visiting the dentist. Develop a habit of brushing your teeth twice a day and especially, do brush before going to bed.

Visit your dentist after every 6 months:

Sometimes you could not see the cavity in your mouth but it is possible that the cavity is in a position where you cannot look. If you visit your dentist, he/she can observe the minor signs of the cavity and it will be treated immediately. In this way, your tooth will also not be damaged. So, if you want to prevent cavities, visit your dentist after every six months.

Avoid sugary snacks:

As we have already discussed that when we eat sugary snacks, we direct the bacteria in our mouth to convert sugars into acid. This acid is very dangerous for the health of your teeth and demolishes the teeth enamel. Consider it as when you eat or drink something other than water, you are making your teeth vulnerable to cavities. So, it would be very helpful for our teeth if we stop eating sugary snacks from time to time.

Use mouth wash:

We know that hygiene is most important when it comes to health. Keeping a good routine and hygiene can even save you from tons of diseases. The same case is with your teeth. So, you should use mouth wash at least once or twice a day to clean your mouth and get rid of harmful bacteria. Using mouth wash will not only decrease the chances of cavities but will also give fresh breath and will cure your gums. Adding mouth wash in your daily life is very beneficial in preventing cavities.

Use dental sealants:

Dental sealant is a thin coating that covers your back teeth or molars. This coating protects the molars from food particles, germs, and harmful bacteria. In this way, the chances of cavity development decline because there will be no contact between acid and your molars. Using dental sealants can be a good decision as they are cheaper as compared to fillings and easily maintainable. Typically, dental sealants last for at least 5-10 years. Dental sealants can help you prevent cavities and you should consider them if you are concerned with the health of your teeth.

Cavities in kids

Even though the tendency to develop cavities increases with age and old people are more likely to get cavities but kids are also vulnerable to cavities. We already mentioned that even babies can sometimes have cavities. Cavities are more common in kids and toddlers as compared to older people and there are numerous reasons behind it. So, cavities in kids are not something to worry about and it is not a rare situation. Research in the United showed that around 60% of American kids under the age of 5 have had cavities. One of the most common reason behind this large figure is that kids below the age of 6 are not able to do brush accurately. Another factor that causes cavities in kids is that do not do floss after taking a meal and even if they do, they do it wrong. Flossing in the wrong can even lead to gum damage. So, parents should supervise and teach their kids about brushing and flossing.

How to cure the cavity?

We have discussed the preventions and the causes of the cavities but if you already have developed cavities, then there is no choice other than medical treatment. It is widely believed that cavities will go away on their own but in reality, this is just a myth and without any proper treatment, the situation will become worse and worse. Some common methods to treat cavities are mentioned below.


The filling is a process in which the dentist will remove the infected part of your tooth and after that, the empty space will be filled. This filling can be of gold, silver, or plastic depending on the preference of the patient. The filling is also used to treat broken tooth or any damaged area of your tooth. Typically, fillings last around 10 years but it totally depends on the type of filling. The most durable type of filling is cast gold filling which can even last for 15 years.

Root canal:

Generally, a root canal is not required and this method to treat cavities is only used when the cavity grows larger and touches the inner soft part of your tooth. This process includes the removal of the damaged soft part of the tooth and later, this space is filled with a filling. If your tooth is damaged severely by a cavity but you do not want to remove your tooth, then a root canal is the best option for you. A root canal is only used in severe cavity cases.


A crown is very much similar to dental sealants. Consider it as a protective layer around your tooth. When a tooth is damaged by a cavity, a crown is used to cover it. This process is very long as compared to others because this will require a customized crown suitable for the size of your tooth. Crowns also have different types depending upon the material used in their manufacturing. Gold, porcelain, and resin crowns are most commonly used.

Fluoride treatment:

Fluoride is the most basic treatment of cavities and is often used at the initial stages. Fluoride treatment is also effective in completely reversing the cavity but if the cavity is just started. Fluoride is a mineral that is very beneficial for our teeth. Fluoride treatment is a very simple treatment of the cavities and it can also be done at home. The process consists of gargling fluoride water and brushing your teeth with fluoride water. The water used during this treatment contains fluoride in large amounts.

Difference between cavity and tooth decay

The two terms; cavity and tooth decay, are commonly considered as the same condition but in actual fact, cavity and tooth decay are completely different things and there is nothing common between them. As we already explained, a cavity is a damaged part of the tooth in a way that there is a small or large hole in the tooth. In the case of cavities, the damaged part of the tooth cannot recover on its own and there are no means to treat a large cavity naturally but a cavity in its initial stages can be treated by some natural methods like fluoride treatment and oil pulling etcetera.

On the other hand, tooth decay is a condition in which the enamel which is the natural coating over our teeth and protects our teeth from any kind of damage erodes. Enamel also protects our teeth from chipping and any kind of tooth breakage. Because of the erosion of enamel, our teeth become unguarded, and bacteria attack them which results in cavities. Tooth decay as compared to cavities is a more severe condition because it can lead to some other complications. In a nutshell, we can say that tooth decay can be a cause of the cavity but it is entirely wrong to say that tooth decay is the cavity.

Final Verdict

We have discussed cavities in detail in this article. It is obvious that avoiding cavities is impossible and you should not even worry about them. Not worrying does not mean to leave them or believe in myths as they will recover on their own. Leaving these conditions untreated will give nothing but more pain and tooth damage. Also, if you will not get some medical treatment, the situation of your tooth will become severe and it will cost you more. If you have discovered any cavity in your tooth or you are in doubt that you have cavity, then you should visit your dentist as soon as possible.
