well different tweens and teens get all their adult teeth at different ages. most should have all their adult teeth by age 14 at the latest.
Not nearly as well. The active ingredient is hydrogen peroxide. It degrades to water and oxygen over time. After expiration, there is still active ingredient, but, depending on long they've been expired, the effect is diminished.
I am currently doing an assignment on this topic and I will soon be able to tell you how fast cola drinks rot teeth, and which brand:
It's unlikely that fillings would ever crush, but theoretically an extremely badly made filling could crush from the pressure of a deep descent. A more common dental issue associated with diving is empty pockets of air in a filling expanding as you ascend and causing pain.
It's worth mentioning that you're a scuba diver to your dentist, and check out DAN(.org?) (Divers Alert Network) for dental health related issues.Answer
No, fillings do not crush, and no, they do not trap air. This is an urban myth. There has never been even one authenticated case of either ever recorded. If you think its your teeth, its most likely your ears, believe it or not, its really hard to tell the difference.
Far more frequent than problems with dental work are sinus problems. One old, hoary way of testing if your toothache is really a sinus problem is to hop on the heel of one foot on the side that hurts. If it throbs every hop, it's sinus and not dentistry.
I realize this sounds like voodoo. The science of it is that a swollen sinus cavity will press down on the same nerve plexus that hurts when an upper tooth gets problematic. However, that bouncing motion will really throb with a swollen sinus but won't do a thing to a tooth ache.
Doubt me? Try it :}
I don't think a filling can be crushed, but if it is fitted badly and there is a pocket of air underneath the filling there is a possibility that as you ascend the air will expand causing the filling to pop out, however I think this rarely happens. Someone mentioned telling your dentist that you are a diver, but unless they are a diver themselves they will have no idea why you are telling them that so you will probably jut get an answer along the lines of'oh really? ? That'snice'
Yes, it will work. If it'll be the best for you or not is another question.

I have been reading on the internet and basically the answer i came across for myself is yes. But not everyday maybe 2 or 3 times a week or everyother day. I first herd of this in my bio class and i guess all i can do is wait and see if it works.
In humans at least, maxillary sinusitis is not related to numbness of the upper teeth. In fact, it can actually be associated with a referred toothache due to irritation of the superior alveolar nerve. If you experience a numb tooth along with maxillary sinusitis, there is a good chance your sinusitis is secondary to the spread of infection from a necrosed tooth. (Dead tooth pulp is numb.)

Image result for What is the purpose of teeth whitening?
The process of tooth whitening lightens the colour of a tooth. Tooth whitening can be achieved by either changing the intrinsic colour or by removing and controlling the formation of extrinsic stains. The chemical degradation of the chromogens within or on the tooth is termed as bleaching.

Main article: Tooth enamel
Enamel is the hardest and most highly mineralized substance of the body and is one of the four major tissues which make up the tooth, along with dentin, cementum, and dental pulp. It is normally visible and must be supported by underlying dentin. Ninety-six percent of enamel consists of mineral, with water and organic material composing the rest. The normal color of enamel varies from light yellow to grayish white. At the edges of teeth where there is no dentin underlying the enamel, the color sometimes has a slightly blue tone. Since enamel is semitranslucent, the color of dentin and any restorative dental material underneath the enamel strongly affects the appearance of a tooth. Enamel varies in thickness over the surface of the tooth and is often thickest at the cusp, up to 2.5 mm, and thinnest at its border, which is seen clinically as the cementoenamel junction (CEJ). Enamel's primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. The large amount of minerals in enamel accounts not only for its strength but also for its brittleness. Dentin, which is less mineralized and less brittle, compensates for enamel and is necessary as a support. Unlike dentin and bone, enamel does not contain collagen. Instead, it has two unique classes of proteins called amelogenins and enamelins. While the role of these proteins is not fully understood, it is believed that they aid in the development of enamel by serving as framework support among other functions. Main article: Dentin
Dentin is the substance between enamel or cementum and the pulp chamber. It is secreted by the odontoblasts of the dental pulp. The formation of dentin is known as dentinogenesis. The porous, yellow-hued material is made up of 70% inorganic materials, 20% organic materials, and 10% water by weight. Because it is softer than enamel, it decays more rapidly and is subject to severe cavities if not properly treated, but dentin still acts as a protective layer and supports the crown of the tooth. Dentin is a mineralized connective tissue with an organic matrix of collagenous proteins. Dentin has microscopic channels, called dentinal tubules, which radiate outward through the dentin from the pulp cavity to the exterior cementum or enamel border. The diameter of these tubules range from 2.5 μm near the pulp, to 1.2 μm in the midportion, and 900 nm near the dentino-enamel junction. Although they may have tiny side-branches, the tubules do not intersect with each other. Their length is dictated by the radius of the tooth. The three dimensional configuration of the dentinal tubules is genetically determined. Main article: Cementum
Cementum is a specialized bony substance covering the root of a tooth. It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Cementum is excreted by cementoblasts within the root of the tooth and is thickest at the root apex. Its coloration is yellowish and it is softer than either dentin or enamel. The principal role of cementum is to serve as a medium by which the periodontal ligaments can attach to the tooth for stability. At the cementoenamel junction, the cementum is acellular due to its lack of cellular components, and this acellular type covers at least ⅔ of the root. The more permeable form of cementum, cellular cementum, covers about ⅓ of the root apex. Main article: Pulp (tooth)
The dental pulp is the central part of the tooth filled with soft connective tissue. This tissue contains blood vessels and nerves that enter the tooth from a hole at the apex of the root. Along the border between the dentin and the pulp are odontoblasts, which initiate the formation of dentin. Other cells in the pulp include fibroblasts, preodontoblasts, macrophages and T lymphocytes. The pulp is commonly called "the nerve" of the tooth.
The following is by and according to the U.S. Department of Labor and particular to the education and training required for a dental assistant. Many assistants learn their skills on the job, although an increasing number are trained in dental-assisting programs offered by community and junior colleges, trade schools, technical institutes, or the Armed Forces. Education and training. High school students interested in a career as a dental assistant should take courses in biology, chemistry, health, and office practices. For those wishing to pursue further education, the Commission on Dental Accreditation within the American Dental Association (ADA) approved 269 dental-assisting training programs in 2006. Programs include classroom, laboratory, and preclinical instruction in dental-assisting skills and related theory. In addition, students gain practical experience in dental schools, clinics, or dental offices. Most programs take 1 year or less to complete and lead to a certificate or diploma. Two-year programs offered in community and junior colleges lead to an associate degree. All programs require a high school diploma or its equivalent, and some require science or computer-related courses for admission. A number of private vocational schools offer 4- to 6-month courses in dental assisting, but the Commission on Dental Accreditation does not accredit these programs. A large number of dental assistants learn through on-the-job training. In these situations, the employing dentist or other dental assistants in the dental office teach the new assistant dental terminology, the names of the instruments, how to perform daily duties, how to interact with patients, and other things necessary to help keep the dental office running smoothly. While some things can be picked up easily, it may be a few months before new dental assistants are completely knowledgeable about their duties and comfortable doing all of their tasks without assistance. A period of on-the-job training is often required even for those that have completed a dental-assisting program or have some previous experience. Different dentists may have their own styles of doing things that need to be learned before an assistant can be comfortable working with them. Office-specific information, such as where files are kept, will need to be learned at each new job. Also, as dental technology changes, dental assistants need to stay familiar with the tools and procedures that they will be using or helping dentists to use. On-the-job training is often sufficient to keep assistants up-to-date on these matters. Licensure. Most States regulate the duties that dental assistants are allowed to perform. Some States require licensure or registration, which may include passing a written or practical examination. There are a variety of schools offering courses-approximately 10 to 12 months in length-that meet their State's requirements. Other States require dental assistants to complete State-approved education courses of 4 to 12 hours in length. Some States offer registration of other dental assisting credentials with little or no education required. Some States require continuing education to maintain licensure or registration. A few States allow dental assistants to perform any function delegated to them by the dentist. Individual States have adopted different standards for dental assistants who perform certain advanced duties. In some States, for example, dental assistants who perform radiological procedures must complete additional training. Completion of the Radiation Health and Safety examination offered by Dental Assisting National Board (DANB) meets the standards in more than 30 States. Some States require completion of a State-approved course in radiology as well. Certification and other qualifications. Certification is available through the Dental Assisting National Board (DANB) and is recognized or required in more than 30 States. Certification is an acknowledgment of an assistant's qualifications and professional competence and may be an asset when one is seeking employment. Candidates may qualify to take the DANB certification examination by graduating from an ADA-accredited dental assisting education program or by having 2 years of full-time, or 4 years of part-time, experience as a dental assistant. In addition, applicants must have current certification in cardiopulmonary resuscitation. For annual recertification, individuals must earn continuing education credits. Other organizations offer registration, most often at the State level. Dental assistants must be a second pair of hands for a dentist; therefore, dentists look for people who are reliable, work well with others, and have good manual dexterity. Advancement. Without further education, advancement opportunities are limited. Some dental assistants become office managers, dental-assisting instructors, dental product sales representatives, or insurance claims processors for dental insurance companies. Others go back to school to become dental hygienists. For many, this entry-level occupation provides basic training and experience and serves as a steppingstone to more highly skilled and higher paying jobs.

An orthodontic finishing positioner for maloccluded teeth to which are
secured coupling members having portions protruding from the sides of the
teeth includes a body constructed of an elastomer base material adapted to
be operatively positioned about the teeth and coupling member of at least
one dental arch of a patient. The positioner body is arcuate in shape and
defines a recess for receiving teeth of at least one dental arch wherein
the recess includes walls defining teeth-engaging surfaces shaped
generally complementary to the surfaces of the teeth of the one dental
arch when the teeth therein are positioned in a predetermined or ideal
orientation. The recess walls further defines a series of indentations
disposed across the teeth-engaging surfaces wherein each indentation being
shaped to nestingly accept a corresponding coupling member so that when
the positioner body is operatively positioned within the patient's mouth
and stretched about the teeth of the one dental arch so that the teeth
thereof are operatively received by the recess of the arcuate-shaped
portion and each coupling member is accepted by a corresponding
indentation, the stretched body effectively grasps the teeth and acts
against the teeth and the coupling member to bias the teeth of the one
arch toward the predetermined orientation. The method of the invention
includes the steps involved in constructing the positioner of the
invention. Such construction steps include the constructing of an
impression-formed model of the teeth and coupling members of the one
dental arch, repositioning the teeth-simulating portions of the model to a
predetermined orientation and utilizing the model, with its repositioned
teeth-simulating portions, as a standard for the formation of the desired
