There are four different types of teeth. molarpre molar Incisors and canines
Incisor- teeth in the very front, sharpest teeth, built to cut food and shaped to shovel the food toward the back of the mouth..
Canine- corners of the mouth, meant for grasping and tearing food, they have very long roots.
Premolar- flat chewing surface because they're meant for crushing food. Molar- last teeth towards the back of your mouth, much bigger than the Premolars and have bigger, flatter chewing surfaces because their job is to chew and grind the food into smaller pieces.
What are your teeth made of? Crown Enamel Dentin Pulp Root Gums Neck
Enamel- White outer surface of tooth, Calcified surface that is stronger than bone.
Dentin-Surface directly beneath enamel that is less calcified, similar to bone, becomes visible with excessive wear to the teeth. (Shock Absorber)
Pulp- Inner most part of the tooth, houses the nerve and blood supply to the tooth. Damage could cause the tooth to die. Crown Root
Plaque- A sticky film that forms on your teeth from the bacteria, food, and saliva in your mouth.
In the BEFORE picture, you can see the buildup of plaque on these teeth with the aid of a disclosing agent. The AFTER picture shows the removed plaque.
How are cavities formed? Bacteria causes a build up of plaque. Plaque acid attacks the tooth The tooth eventually rots away Plaque can be removed by brushing and flossing
Tooth Decay Tooth Decay -Cavities
Gingivitis- Caused by the accumulation of plaque on the tooth and under the gum tissue. gingivitis healthy
Gingivitis- Causes the gums to become red, inflamed, and to bleed and hurt when brushing.
Tartar- Plaque that is not removed will sit on the teeth and below the gums, will harden or mineralize, thus forming tartar.
Tartar is also an irritant to the gum tissue that can cause gingivitis Tartar can only be removed by your dental hygienist.
