What is Saliva?
It is a Solution: a homogeneous mixture of substances that combine to form a single phase, it is in the liquid phase.
The solution consists of
The 2% Solute consists of electrolytes, enzymes, and antibacterial compounds
What Causes Dental Cavities?
Specific bacteria such as Streptococcus mutans cause cavities.
These bacteria are aerobic meaning they require oxygen to survive; having a dry mouth increases the chance for cavities.
Cavity causing bacteria are different than the bacteria that causes gum disease, which live in an anaerobic environment. Both of these bacteria can be passed from person to person.
Plaque, is also known as Biofilm.
A microbial biofilm is a layer of prokaryotic organisms which adhere to a surface and are coated with a polysaccharide layer.
The biofilm increases the prokaryotic cells survival through increased defense, availability of nutrients, cellular communication, and the ability to transfer genetic material to each other.
A polysaccharide is composed of more than one sugar molecule. Carbohydrates, Starch, Cellulose, and Glycogen are polysaccharides.
How the cavity is formed
Underneath the plaque, the bacteria produce acids as a by-product of their metabolism.
The acids produced by the bacteria break down tooth structures, this is also known as demineralization.
Once the demineralized tooth structure grows into an advanced bacterial colony, it is than defined as a cavity.

Tackling Tooth Decay
Wisdom Teeth : Austin Family Dental
Wisdom teeth, also called your third molars can help you with chewing if your jaw is big enough to handle the extra four teeth.
Variations in DNA which are known as mutations when humans reproduced around 2.4 million years ago caused their jaws to become smaller and brains become bigger. This mutated genetic information was passed onto offspring because it was a favorable trait.
As the brain grew larger and the jaw became smaller, there eventually was no room for wisdom teeth in the new smaller jaw as the favorable trait of a larger brain was passed on. Currently, we have Oral Surgeons to remove wisdom teeth that are impacted or infected.
If you are born without your wisdom teeth, you are at an evolutionary advantage. As of now, we use oral surgeons to remove wisdom teeth, but the genetic mutation of no wisdom teeth is a beneficial trait.

Gum Disease and Gingivitis : Austin Family Dental
What is Gum Disease?
Periodontal disease is also known as Gum Disease and is defined as:
What Causes Gum Disease and Gingivitis?
The tissues and supporting bone around a tooth may be attacked by specific bacteria, this may cause the teeth to become loose and cause tooth loss,. This bacteria can cause a gum infection. which is different than the bacteria that cause a cavity.
The specific bacteria that cause Gum Disease, Gingivitis, and Periodontal Disease are Anaerobic bacteria. This means that they can only survive in an environment without oxygen.
This is why flossing and brushing your teeth daily is important. You remove the debris, disrupt the biofilm forming, and allow oxygen to reach the pockets between your gums and teeth. 3.

Acid Erosion on Teeth : Austin Family Dental
There are three main acid erosion patterns that have been associated with different likely causes (A, B, and C).
A = Diet
B = GERD - Gastroesophageal reflux disease also known as hot burps
C = Bulimia or Alcoholism
Here is link to a visual of what the patterns look like
Why do the patterns form this way?
A = These acids come from an outside source such as food or something your drink. When you eat acidic foods like soda and sour candy, the chewing surface, tongue, and cheek surfaces on the back molars begins to get chalky or demineralize.
B = These acids are internal. Stomach acid travels up your throat and into your mouth, usually when you are sleeping. This causes significant tooth loss since you are swallowing less when you are sleeping and your mouth is producing less saliva which protects your teeth from acidic attack.
C = When the acids start attacking the front teeth on the tongue side, it may be an indication of recurrent vomiting or alcoholism. These acids come from within you and are intrinsic acid.
Where does the Acid Come From, Internal or External Sources?
A = Extrinsic, an outside source of acid such as dietary acids.
B & C = Intrinsic, an internal source of acid such as gastric acids.

What are Dental Crowns : Austin Family Dental
Dental Crowns are artificial replacement teeth. They are used to replace a missing tooth, cover and support a tooth, or reshape a tooth.
The material being used depends on what is trying to be done with the dental crown, what look the patient is going for and if the individual has a metal allergy. The dental crown can be made of ceramic, gold, porcelain fused to metal, and base metal alloys.
Dental Crowns are used for
My education consists of a Bachelor of Liberal Arts Degree in Business Administration & Art. Since then I have taken classes in chemistry, organic chemistry, biology, physics, and microbiology to pursue a career as a dentist; I studied to apply for dental school to become a dentist but was unable to pursue it.
