The Basics of Teeth in the Mouth

The human mouth is home to up to 32 permanent teeth, with another 8-20 primary baby teeth eventually falling out to make room for the full set of adult teeth. Each type of tooth plays an important role in allowing us to eat, speak properly, and maintain oral health.

What Are the 4 Types of Teeth?

There are four main types of teeth in the human mouth: incisors, canines, premolars, and molars. Let's take a closer look at what makes each type unique:

  • Incisors - The front four teeth on the top and bottom that help bite off and chew pieces of food.
  • Canines - The pointed teeth on each side of the incisors that help tear food.
  • Premolars - Behind the canines, these teeth help hold and crush food.
  • Molars - Big, flat teeth in the back that grind food into smaller pieces, aiding digestion.

How Many of Each Tooth Do Adults Have?

The typical number of permanent teeth found in adult mouths are:

  • 8 incisors (4 on top, 4 on bottom)
  • 4 canines (2 on top, 2 on bottom)
  • 8 premolars (4 on top, 4 on bottom)
  • 12 molars (6 on top, 6 on bottom)

This equals 32 total teeth that work together to serve critical oral health functions.

Functions of Different Types of Teeth

Each variety of tooth plays special roles that allow us to eat a wide array of whole foods that require biting, chewing, tearing, and grinding down before swallowing. They also enable proper speech and support overall health.

Incisors

These front teeth perform a few key jobs:

  • Biting off pieces of food
  • Cutting food into smaller bits
  • Supporting proper pronunciation of words and syllables

With their chisel-shaped tops, incisors are perfectly designed for these cutting and biting functions. As they work in conjunction with the lips and tongue, incisors support clear speech. Any damage to these teeth can result in issues speaking correctly.

Canines

The canine teeth have the longest roots of all tooth types. They serve to:

  • Rip and tear food
  • Grip pieces of food
  • Support facial structure

These sharp, pointed teeth complement the incisors in grabbing and tearing off bites of food with their unique shape. With roots that extend below the gums, canines also provide support for the structure of the face.

Premolars

Set behind the canines, premolars handle more chewing forces than incisors and canines. Their duties are to:

  • Hold and crush food
  • Assist molars with grinding

Premolars start breaking down pieces of food further to ease the burden on the molars as food makes its way towards the back of the mouth to be fully ground down.

Molars

The molars contain broad surfaces specifically made for grinding and pulverizing food into tiny particles. With great force, they:

  • Grind solid food into mush
  • Aid in digestion as first stage of breaking down food
  • Enable food particles to be easily swallowed

Positioned furthers back in the mouth, molars grind down food into digestible mush. They play a major part digestion by starting the breakdown of solid food pieces.

Impact of Losing Teeth on Oral Health

Ideally, natural permanent teeth should last for life with proper oral care and minimal decay or damage. But genetics, poor hygiene, gum disease, injury, and cavities can lead to lost teeth over time. Missing teeth negatively impact:

  • Speech
  • Chewing capability
  • Facial muscle support
  • Shape of face
  • Nutrition

Effects of Missing Teeth

Losing teeth creates significant gaps that allow remaining teeth to shift and drift. This leads to:

  • Crooked teeth
  • Change in bite alignment
  • Less balanced facial structure
  • Jaw pain issues
  • Greater impact on other teeth
  • Tooth decay
  • Eating challenges

Just a single missing tooth makes chewing on the side with the gap much more difficult. Nutrient-rich foods like fruits, vegetables, nuts, and meats may have to be avoided since chewing and biting capacity is diminished.

Replacing Lost Teeth

For those missing multiple permanent teeth or struggling with the side effects of tooth loss, modern dentistry offers excellent tooth replacement options:

  • Dental implants - Artificial teeth fused to metal posts surgically embedded in the jawbone for a close to natural replacement look and feel.
  • Dental bridges - False teeth cemented to crowns placed on surrounding natural teeth to bridge the gap left by lost teeth.
  • Partial and full dentures - Removable customized appliances that use metal clasps with fake teeth to improve chewing ability, speech, and appearance.

With advances in cosmetic and restorative dental treatments, lost natural teeth can be replaced with great natural aesthetics and restored oral functioning.

The Impact of Teeth on Overall Health

Teeth might seem like relatively simple physical structures, but they play interconnected roles that powerfully influence total body health. From mental health to heart health and beyond, teeth enable critical bodily functions.

Chewing and Nutrient Absorption

The teeth act as the first step in the intricate digestive process. Chewing breaks down food to unlock nutritive value. When teeth don't properly grind down vitamins, minerals, and other nutrients, the GI system can struggle with absorption to nourish the body optimally. Poor chewing can also limit the diversity of vegetables, fruits, fiber, lean protein, and other essential foods you're able to eat.

Speech and Communication

Teeth play a part in verbal communication and speech clarity. When front incisors are lost or crooked, the lips, tongue, cheeks, and jaw don't align correctly for proper enunciation of words. Missing teeth lead to muffled and imprecise speech.

Facial Structure and Muscles

Teeth and jaws provide significant structural integrity for facial muscles, structure, and aesthetics. When teeth are missing, facial sagging and collapse can occur over time. Jaw alignment is also compromised, leading to pain disorders like TMJ or TMD.

Heart Disease and Diabetes

Inflammation fueled by oral bacteria from dental diseases may potentially contribute to plaque buildup in arteries that leads to some cardiovascular diseases. Poor blood sugar control in diabetics is also linked to severe gum disease.

As you can see, teeth and oral health intersect with whole body wellness in diverse ways. Protecting teeth from decay preserves both health and quality of life.
