  Tooth extractions: Why are extractions needed? Why might a tooth extraction not be a good idea?
In general, as periodontal disease worsens, a tooth is supported by less and less surrounding bone, often to the point where the tooth becomes loose.
Wisdom teeth are typically in a region of the mouth that is hard to clean, thus placing them and their neighboring tooth at greater risk for decay and periodontal disease.
While extracting a tooth might be less expensive than the other treatment options your dentist proposes, it may not be the least expensive treatment in the long-run.

 Colyer Institute- Captivity Disorders in Elephants Impacted Molars and Broken Tusks
Normal abrasive wear and tear erode away the molar(s) "in-use", while the eruptive forces produced by the growth of its succedaneus tooth continues to push the "in-use" molar forward until it is exfoliated or finally comes into contact with the cortical plate of bone shaping the anterior wall of the mandible.
An impacted molar is usually inclined medially because of the strong influence of the animal's lip and cheek musculature, and often is accompanied by supra-eruption of the tooth.
The first clinical sign of a functionally significant molar malocclusion, aside from the visually obvious mal-positioning of the teeth, which may or may not be apparent through causal observation, is a change in the texture and coarseness of the animal's fecal mass usually associated with weight loss.

  Molar (tooth) - Wikipedia, the free encyclopedia
Molars are the rearmost and most complicated kind of tooth in most mammals.
The types of molars in the human mouth are the maxillary first molars, maxillary second molars, maxillary third molars, mandibular first molars, mandibular second molars, and the mandibular third molars.
This kind of molar is found in mammals that wear their teeth a lot, such as the horse.

Surrounded by the dentine is the pulp cavity, which is filled by the tooth pulp, a highly vascular and nervous mass of branched connective tissue cells, which, in a young tooth, has a layer of epithelial cells, the odontoblasts,lying close against the wall of the cavity and forming new dentine.
The cutting or grinding part of the tooth is first formed, and the crown gradually closes round the dental papilla, so that at last, when the root is fornied, the central part of the papilla remains as the pulp cavity surrounded by dentine except at the apex of the root.

 Guideline 43 Section 3: Indications for removal
Third molar removal should be considered in cases of external resorption of the third molar or of the second molar where this would appear to be caused by the third molar.
Pain associated with the lower third molar tooth is commonly exacerbated by the upper third molar biting on the gum flap, causing pain and discomfort.
If the third molar tooth is close to the surface or has broken through the surface in relation to an upper or lower denture then it is appropriate to remove that tooth before or as soon as symptoms arise, as they are likely to persist and become more severe if the tooth is not removed.

 Guidlines for Tooth Preparation
Tooth preparation is the single most important aspect of restorative dentistry because it establishes the foundation for whatever restoration is being placed.
The recommended amount of tooth reduction for metal ceramic restorations is 1.2-1.5 mm of labial reduction, 0.5-1.0 mm of lingual reduction; depending upon whether it will be metal or veneered with porcelain; and 2.0 mm of incisal or occlusal reduction.
The cross section of the tooth shown in (Fig.1) is an unerupted mandibular premolar that was removed for orthodontic purposes.

 Equine Dentistry
If a horse has lost a tooth, or a tooth has been extracted for some reason, the opposite tooth that was in occlusion, has nothing to wear against.
The tooth and its surroundings can be sensitive, and having lips pulled into a sharp wolf tooth is not a pleasant experience for the horse either.
If the rows of molars (or incisors for that matter) are not aligned properly (for example in a horse with an overjet or underjet) a part of the tooth will not be in occlusion and will not wear down.

Tooth transition period starts approximately at the age of 6, and ends at around the age of 12 or 13.
At this time, parents must remember to remind their children to clean the ‘six-year molar' by brushing the very back tooth with a toothbrush and fluoride toothpaste and thoroughly brush all the tooth.
Generally speaking, we cannot assure whether the tooth alignment is irregular or not until all the permanent teeth have replaced the deciduous teeth and the development of jawbones have stabilized.

 The elephant molar teeth
The molar teeth are cheekteeth with ridges, which are developed for grinding food, hence the name molar, which means "millstone".
The molars of different species differ considerably, and is one of the most important key´s for paleontologists to determine the species of a fossil, since teeth are one of the most common findings in excavation sites.
The molar teeths were also an inspiration for the evolutionists to name different species, Mastodon means "breast-toothed" and Stegodon means "roof-toothed", and Loxodonta means "sloping teeth".

 Set of artificial molar teeth - Patent 4208794
What is considered to be novel with the artificial molar teeth of this development is that they are designed to carry out a successive contact which is comparable to the cutting action of a scissor.
Considered from the constructional standpoint the successive contact is predicated upon a reduction of the tooth angle or angle of inclination 10 of inclined contact surface 12 and/or a likewise stepped reduction of the size of the friction path or length 14 of surface 12 proceeding from the first premolar to the second molar.
At the molar region the fiction path is selectively disposed likewise at the buccal protuberances of the upper or at the lingual protuberances of the lower molars.

 MMP-2 in rat first molar tooth germ
Tooth germ development is associated with morphological and biochemical changes of the dental papilla and enamel organ.
Mechanical separation of the tooth germ from 10-day-old rats showed that the gelatinolytic activity was localized mainly in the dental papilla and not the dental organ.
Extracts of molar tooth germ of 0 to 15-day-old rats demonstrated three gelatinolytic enzymes by enzymography assay that were characterized as MMP-2, because they were inhibited by 1,10-phenanthroline and EDTA, exhibited activities at a neutral pH and were extracted from the extracellular matrix containing a fraction of tooth germ (Triton X-100 insoluble).

Key ingredients in preventing tooth decay and maintaining a healthy mouth are twice-daily brushing with an ADA-accepted fluoride toothpaste; cleaning between the teeth daily with floss or interdental cleaners; eating a balanced diet and limiting snacks; and visiting your dentist regularly.

 Dental Sealants | Tooth Sealants
The first dental sealant to be placed is usually on the fissure of the first permanent molar tooth, once the chewing surface of the tooth has erupted completely beyond the gum.
Except for the wisdom teeth, which come through much later, the molars and premolars continue to erupt until eleven-thirteen years of age and the chewing surfaces of these teeth can be sealed after they have erupted beyond the gum.
Firstly the tooth surface is thoroughly cleaned with a paste and rotating brush by your dentist or hygienist.

Once the tooth is moved into the arch in its final position, the gum around it will be evaluated to make sure it is sufficiently strong and healthy to last for a lifetime of chewing and tooth brushing.
In some circumstances, especially those where the tooth had to be moved a long distance, there may be some minor “gum surgery” required to add bulk to the gum tissue over the relocated tooth so it remains healthy during normal function.
The orthodontic maneuvers needed to manipulate an impacted molar tooth can be more complicated because of their location in the back of the dental arch.

The first molar typically surfaces, or erupts, when an individual is about the six years of age; the second molar appears behind the first molar at the age of twelve.
The third molar, commonly called the wisdom tooth, is the last molar to develop and usually erupts posterior to the second molar during the late teens and early twenties.
Unfortunately for the majority of today's young adults, their jaws are not large enough to allow the eruption of the third molar tooth in a normal, healthy and functional position.
