08 September · 5 minutes

Just as many people ask ‚Äúwhat is plaque on teeth?‚ÄĚ as ‚Äúwhat is tartar on teeth?‚ÄĚ So we‚Äôre going to take a look at both. While you‚Äôve probably heard that each of these is bad, you might not have learned exactly what they are. In this article, we‚Äôll answer all your questions, from ‚Äúwhat does plaque vs tartar on teeth look like?‚ÄĚ to ‚Äúwhat causes plaque and tartar and how do they build up?‚ÄĚ Most importantly, we‚Äôll address how to prevent plaque and tartar buildup on teeth and how to remove them once and for all. Let‚Äôs take a look at all you need to know about dental plaque and tartar.

What is plaque? And what is tartar?

Let’s begin with the basics. What is plaque? And what is tartar? Well, they’re actually two different things, let's start by taking a look at plaque: what is it and what is it made of? The dental plaque that you can find on teeth is a sticky and colorless layer that builds up on the tooth surface due to the accumulation of bacteria and food debris. Among other oral diseases, the accumulation of bacterial plaque is the main cause of cavities and gingivitis, hence its need for removal.

Next, what is tartar and what does it look like on teeth? The tartar on teeth is simply the calcification of dental plaque, which is why it's also referred to as dental calculus. While bacterial plaque is colorless, tartar is usually yellowish or brown. When we don't brush our teeth properly, the accumulation of plaque can solidify, giving rise to tartar. Tartar or dental calculus can build up on or between the teeth and in the gums, where it is more difficult to remove.

What is the difference between plaque and tartar on teeth?

Essentially, tartar is the next level of plaque. Unlike plaque, which is sticky, tartar is hard.

Their consistencies go hand in hand with another main difference between plaque and tartar: plaque removal from teeth is simple vs tartar removal, which is a bit more complicated. If you have tartar buildup on or between your teeth, you’ll need to go to the dentist immediately in order to remove it and prevent possible dental diseases.

So overall, when discussing plaque vs tartar on teeth, tartar is the progressed and more dangerous plaque.

How does plaque or tartar buildup form and what is it made of?

Bacterial plaque is formed by the accumulation of food debris on the tooth surface, which is colonized by various bacteria found in the oral cavity that feed on these debris. So, what exactly is the plaque on teeth made of? Just that; the combination of food remains, along with bacteria and other elements. They build up on the teeth and create the sticky substance known as dental plaque.

Your next question might be, so how does tartar form and build up? Tartar or dental calculus buildup forms when dental plaque is not cleaned. When the bacterial plaque comes into contact with saliva, there is a reaction that calcifies the plaque, turning it into tartar. Tartar buildup on or between the teeth should be avoided at all costs, as we mentioned earlier, because it’s more difficult to remove and more dangerous to your oral health.

What causes dental plaque and tartar buildup on teeth?

Now that we understand what they are, we need to look at what causes dental plaque and tartar buildup on teeth. The main cause of dental plaque is usually not maintaining good oral hygiene. If plaque is not properly removed by brushing and using floss, it will accumulate and calcify, forming tartar or calculus teeth. Since both are interrelated, it could be said that poor oral hygiene is also the main cause of tartar on teeth.

That being said, when talking about what causes plaque and tartar on teeth, we should also consider that sometimes oral hygiene can be difficult to maintain, like with braces. Plaque caused by braces is relatively frequent, since these devices make it difficult to thoroughly brush the teeth and gums, and may facilitate the buildup of plaque and tartar on the teeth around the device.

Although poor oral hygiene is the main cause of both, it is also true that plaque and tartar on the teeth don’t come from bad brushing exclusively. There are other factors that can influence their development, for example, if we eat a lot of sugar, the pH of our saliva will be altered and we're more likely to create and accumulate dental plaque and tartar buildup. On the other hand, there are people who naturally have a more acidic pH, which creates the ideal climate for plaque and other oral diseases such as cavities.

Types of bacterial plaque and dental calculus on teeth

Depending on where the problem is located on the teeth, there are different types of dental plaque and calculus. Let’s take a look at the types below.

Types of plaque on teeth

Dental plaque can be located in various places in the mouth, and depending on where it accumulates, determines the type. Let’s take a look at the types of bacterial plaque on teeth:

  • Marginal plaque is on top of the tooth's surface
  • Coronal plaque is located plaque on the border of the teeth and gums
  • Subgingival plaque accumulates in the pits of the gingival sulcus and within the periodontal pockets, causing tartar pockets in the gums.

Types of tartar or dental calculus

Like plaque, tartar or dental calculus can also appear in various places around the mouth, but unlike plaque, there are only two types of dental calculus:

  • Supragingival tartar is found on the border of the gums and teeth
  • Subgingival tartar accumulates under the gums, and can form in the periodontal pockets.
