Protect your teeth from tooth decay and cavities. Learn what the causes are for both as well as tooth decay and cavities prevention today.

Cavity and tooth decay is one of the world's prevailing oral health problems. According to the WHO, it affects more than 3.5 billion people around the world. If we focus on the U.S., nearly 92% of Americans have had several cavities throughout their lifetime.



Despite these alarming figures, dentists can help in preventing cavities and tooth decay. Cavities prevention and tooth decay prevention is the only way to keep a healthy mouth. Today we will look at certain aspects of cavity and tooth decay and how you can prevent them.

What Is a Cavity?

A cavity is a small hole (sometimes several) that occurs on the tooth's outer part. Initially, you may not feel the hole, but it will slowly grow more extensive as the enamel (outer part of the tooth) begins to wear away. A cavity that is left unchecked will gradually become a severe health problem.

There are also different kinds of cavities, something many people are unaware of when talking about cavities. Let's take a look at the three cavity types.
  • Root cavity
  • Pit and fissure cavity
  • Smooth-surface cavity
Root cavities form on the roots of the tooth. Pit and fissure cavities appear on the grooves of the biting surfaces of molars. Smooth-surface cavities occur on the smooth surfaces of teeth.

What Causes a Cavity?

Teeth are continually creating plaque, and it begins to form between 4 to 12 hours after brushing, which is why it's crucial to brush your teeth at least twice a day. Plaque is not a problem, as everyone has it. It's the bacteria found on the plaque that will cause problems.



Since your teeth cannot repair the outer layer (enamel), our teeth's enamel will begin to weaken as time passes. The teeth will then be more likely to be affected by bacteria found in our mouths. The bacteria on the plaque of the teeth can form acid, which will lead to a cavity or hole.

Cavity Symptoms

The symptoms of having a cavity can vary, as it depends on the type, location, and severity. As mentioned before, you may not know you have a cavity until it's more advanced; another reason why the best cavities prevention is regular dental visits. If the cavity does reach an advanced state, these are the most common symptoms.


  • Tooth sensitivity
  • Brown or black stains on a tooth
  • Toothache
  • Pain when you bite down
  • Visible holes in your teeth
  • Moderate to intense pain when eating or drinking something sweet, hot, or cold



If you notice any of these symptoms, promptly contact a dentist's office because ignoring a cavity will lead to far worse problems that can start many health problems. If you don't have any of these symptoms, it doesn't mean you're in the clear. As tooth decay is another common dental problem, and tooth decay can eventually turn into a cavity.

What Is Tooth Decay?

Tooth decay is a continuous tooth disease caused when the enamel is compromised, and the tooth is exposed to harmful oral bacteria.

That is why tooth decay is different from a cavity, as the cavity is the hole that forms because of tooth decay.


The acid created by the bacteria found on the plaque begins to remove minerals in your tooth's hard, outer enamel. Once the enamel is gone, the bacteria and acid can enter your teeth' next layer, the dentin. The dentin is softer than enamel and less resistant to acid. 



The dentin has tiny tubes that directly interact with the tooth's nerve; if the acid enters those tubes, it causes sensitivity. Advanced tooth decay requires immediate dental intervention to avoid further damage.

What Increases Tooth Decay?

Sugar and starch are what causes the bacteria to start forming acid. If you add poor dental hygiene into this mix, it enhances the effects. 

But other factors influence tooth decay as well.

  • Some foods and drinks

Any food that clings onto your teeth, as bacteria feed off anything that sticks onto your teeth.

  • Lack of fluoride

Fluoride is a mineral that rebuilds tooth enamel and reverses tooth decay. 

  • Dry mouth

Saliva helps wash away food and plaque. And some substances found in saliva can counter the acid from the bacteria.

  • Heartburn

Heartburn can create stomach acid to flow into your mouth. Stomach acid will cause your enamel to wear away.

  • Constant snacking and drinking


As already mentioned, bacteria feed off of food and drinks. If you are continuously eating or drinking, it provides constant fuel.


Tooth decay prevention is possible, and tooth decay treatment is also very effective. Let's consider some of the ways you can prevent this oral health problem

Tooth Decay Prevention

The best tooth decay prevention is regular dental cleanings, as dental staff will have the proper tools to keep your teeth clean and healthy. On top of that, they will be able to catch any developing tooth decay or cavity. But what can you do while you arrange your next dentist appointment?

  • Brush your teeth regularly 

You have heard it already, brush your teeth after eating and at least two times a day. And if possible, use fluoride-rich toothpaste.

  • Use mouthwash


An excellent way of removing food and drink particles is regularly rinsing with a fluoride mouthwash.


What happens if you do have tooth decay or a cavity? Let's take a look at the different treatments. 

Tooth Decay and Cavity Treatments

There are several options for treating these two problems, and your dentist will recommend the best one for your teeth. Here are the possible cavities and tooth decay treatments:

  • Fluoride treatments

If you need help in getting more fluoride, your dentist may recommend a fluoride treatment.

If a cavity has formed, then the best way to fix it is by filling it with composite material.

  • Crowns

If the tooth decay is severe, it may be best to cap the whole tooth with a crown. This avoids further damage to the tooth.

  • Root Canal

If the tooth decay has reached the tooth's roots, it will need to be removed and replaced with a dental bridge or implant.

Tooth Decay and Cavities Prevention Is Vital to Being Healthy

Don't risk unnecessary damage to your teeth or health by putting off tooth decay and cavities prevention. You only need good dental hygiene and regular dental checkups. By doing this, you will have a beautiful and healthy smile.
