Human mouths contain an impressive collection of teeth that each serve a distinct function in terms of chewing food and breaking it down for digestion. Teeth are essential components of overall oral health.


They help break down food by crushing or cutting their teeth before swallowing. The majority of people have 32 teeth. However, some have more, while some are smaller. This is because the enamel (the protective layer on the outside of the teeth) is the strongest component in your body.


Teeth are available in many kinds of shapes and sizes. They vary from person to person. Certain people's teeth are naturally bigger, shorter, or smaller than the rest. Certain tooth edges may not be completely straight, and they may also have tiny lines, giving them an impression of a groove.


Teeth are impressive structures designed to aid the digestion of food. Understanding the various shapes and types of teeth provides insight into their functions while emphasizing the necessity of maintaining good oral hygiene practices .

What Are the Four Types of Teeth?


There are different kinds of teeth, and each has a specific purpose. There are four kinds of permanent teeth found in humans:


  • Incisors
  • Canines
  • Premolars
  • Molars

Incisors

Your incisors are the front teeth in your mouth. A majority of individuals have four incisors in the upper jaw and four in the lower. This includes the front two teeth as well as the teeth to the opposite side.

Each incisor has one sharp edge, which can help cut through food when you chew.


Canines

Canine teeth are named due to their resemblance to the dog's fangs. They're sharper than other kinds of teeth. The majority of people have four canines, one in each quadrant (upper right, left and upper left, lower right, and lower left).

Canine teeth are designed for tearing and grasping foods.


Premolars

Premolars are also known as bicuspids. They are located behind the canines.

Humans have 8 Premolar teeth, 4 in the upper jaw and 4 in the lower jaw. They perform crushing and grinding of the food.


Molars

The molars teeth are the strongest teeth of your mouth. The majority of chewing, approximately 90%, is done there. The majority of adults have 12 molars, with three on each side of the upper and lower jaw.

Molar teeth include wisdom teeth (third molars) are the last teeth to emerge in your mouth.

Since molars are your primary eating teeth, they're excellent for crushing and grinding your food items.

What Are the Shapes and Functions of Teeth?


Teeth are available in a variety of shapes and perform different functions according to their size and shape. The different tooth shapes help in grinding, tearing, and chewing the foods to ensure effective digestion.


How Can A Dentist Change the Size or Shape of Teeth?


If you're thinking of trying to change your smile, the dentist will be able to offer suggestions in accordance with your requirements. There are many possibilities for dentists to employ to change the shape of teeth are:


  • Reshaping the tooth (changing the size from small to large and large to small:
  • Bonding of teeth (applying tooth color resin to fill empty spaces and reshaping the teeth)
  • Dental crowns (lengthen short teeth to change the overall appearance)
  • Orthodontics (aligning the teeth position)
  • Dental veneers (cosmetic procedures which act as a fine shell that's bonded to the tooth's surface)

How To Get Rid Of Bad Breath?

Effective bad breath remedies include:

Gentle and regular scraping of the tongue

Regular oral care practices such as daily brushing and flossing

Professional deep cleanings and plaque removal

The ongoing use of oral probiotics.

How Probiotics Work To Control Bad Breath

One, the probiotics compete with the existing bad bacteria and reduce their presence by “crowding them out”

Two, the probiotics produce BLIS or “bacteriocin-like-inhibitory-substances” which is a technical way of stating that one probiotic strain (bacteria) can produce a substance that inhibits or kills off other bacteria. Three, by working to control gingivitis, gum disease and tooth decay these probiotics reduce the very sources of bacteria-generated odors in the mouth.

How Do Oral Probiotics Work to Fight Tooth Decay?

  • First, oral probiotics can break into and colonize your mouth's biofilm, replacing the "bad" bacteria with good.
  • Second, the beneficial oral probiotics compete against the bad bacteria. In effect they crowd out the "bad" bacteria by establishing themselves in the limited space of the biofilm.
  • Third, now, with a lower volume of S. Mutans, and other acid-forming bacteria, the teeth and gums are not under the constant, disintegrating attack of acids.
  • Fourth, at the same time, the oral probiotics are producing alkaline byproducts. This action not only reduces the acids but inhibits the growth of "bad" bacteria as they thrive in acidic environments.
  • Fifth, as a part of the biofilm, the oral probiotics are able to make their way into those difficult to reach deep areas of the teeth and gums. Once there they can continuously work, 24/7, to create a balanced environment that inhibits tooth decay and gum disease while promoting the healing process.

How do Oral Probiotics Help Against Gum Disease?

  • First, our oral probiotics are chosen for their ability to penetrate into and to colonize within the biofilm (plaque) and to survive in the oral environment
  • Second, these oral probiotics have the ability to successfully compete against the harmful bacteria. There are limited resources in the biofilm and with more beneficial bacteria present then fewer harmful bacteria can exist
  • Third, it is not the presence of plaque that is so much the problem, it is the acids and toxins produced by certain bacteria that lead to gum disease and tooth decay. Fewer harmful bacteria in the plaque=lowered toxins and acids
  • Fourth, our oral probiotics improve your mouth's pH balance. This has the effect of reducing acid levels and establishes a pH level that inhibits the growth of harmful bacteria
  • Fifth, unlike brushing or flossing our oral probiotics work their way into those difficult to reach "hideout" zones and so they will work “around the clock” and not just when you brush or floss

Studies have shown a clear reduction in plaque levels and gingivitis symptoms when oral probiotics were administered to patients with moderate to severe gingivitis.
