Professional teeth cleaning (also known as (mineralized plaque) that may develop even with careful brushing and flossing, especially in areas that are difficult to reach in routine toothbrushing. It is often done by a . Professional cleaning includes and and if too much has accumulated. This involves the use of various instruments or devices to loosen and remove deposits from the teeth., literally a preventative treatment of a disease) is a procedure for the removal of
As to the frequency of cleaning, research on this matter is inconclusive. That is, it has , author of , has even questioned “Is Tooth Cleaning a Scam?” been shown that more frequent cleaning leads to better outcomes that it does not. A review of the research literature on the question concluded “[t]he research evidence is not of sufficient quality to reach any conclusions regarding the beneficial and adverse effects of routine scaling and polishing for periodontal health and regarding the effects of providing this intervention at different time intervals” This conclusion was reaffirmed when the 2005 review was updated in 2007. Thus, any general recommendation for a frequency of routine cleaning (e.g. every six months, every year) has no empirical basis. Moreover, as economists have pointed out, dentists (or other dental professionals) have an incentive to recommend frequent cleaning because it increases their revenues. Law professor
Most dental hygienists recommend having the teeth professionally cleaned every six months. More frequent cleaning and examination may be necessary during treatment of dental and other oral disorders. Routine examination of the teeth is recommended at least every year. This may include yearly, select . See also identification procedure and removal.
Good oral hygiene helps to prevent cavities, tartar build-up, and gum disease.
Fillings using high-quality dental porcelain help restore tooth function and protect your tooth from further damage by bacteria.
A used to restore the function, integrity and of missing tooth structure. The structural loss typically results from or external trauma. It is also lost intentionally during tooth preparation to improve the or the physical integrity of the intended restorative material. Dental restoration also refers to the replacement of missing tooth structure that is supported by dental implants. or is a
Dental restorations can be divided into two broad types: is a restorative technique used to fill the space where the normally resides. and . All dental restorations can be further classified by their location and size. A
Crowns are often used to improve the strength or appearance of teeth.
The most common method of crowning a tooth involves using a of a prepared tooth by a to fabricate the crown outside of the mouth. The crown can then be inserted at a subsequent dental appointment. Using this of tooth restoration allows use of strong requiring time consuming fabrication methods requiring intense heat, such as metal or firing which would not be possible to complete inside the mouth. Because of the expansion properties, the relatively similar material costs, and the aesthetic benefits, many choose to have their crown fabricated with .
The main disadvantages of restoration with a crown are extensive irreversible tooth preparation (grinding away) and higher costs than for direct restorations such as amalgam or . The benefits, as described above, include long-term durability and evidence-based success as compared to other restorations or no treatment.
The crowning of two fairly large molars to sling a bridge between them for a missing tooth is a costly and sometimes oversold procedure. The increased food and bacteria trapping of the underside of the bridge often offsets the benefits of the bridge element in maintaining the positions of the opposing teeth and the loss of the ease of use and mouth feel of two big natural teeth.
It is usually the damage to a tooth that dictates the need for a crown, and alternative treatments are usually less effective. Risks and benefits can be weighed based on the priorities of the patient.
Bridges help restore gaps left from a missing tooth.
Types of bridges may vary, depending upon how they are fabricated and the way they anchor to the adjacent teeth. Conventionally, bridges are made using the . However, bridges can be fabricated directly in the mouth using such materials as .
A bridge is fabricated by reducing the teeth on either side of the missing tooth or teeth by a preparation pattern determined by the location of the teeth and by the material from which the bridge is fabricated. In other words, the abutment teeth are reduced in size to accommodate the material to be used to restore the size and shape of the original teeth in a correct alignment and contact with the opposing teeth. The dimensions of the bridge are defined by Ante’s Law: “The root of the teeth has to equal or surpass that of the teeth being replaced with pontics”.
The materials used for the bridges include , fused to metal, or in the correct situation porcelain alone. The amount and type of reduction done to the abutment teeth varies slightly with the different materials used. The recipient of such a bridge must be careful to clean well under this prosthesis.
When restoring an space with a fixed partial denture that will crown the teeth adjacent to the space and the gap with a , or “dummy tooth”, the restoration is referred to as a . Besides all of the preceding information that concerns single-unit crowns, bridges possess a few additional considerations when it comes to case selection and treatment planning, tooth preparation and restoration fabrication.
Dentures can help with mastication as chewing ability is improved by replacing edentulous areas with denture teeth.
, also known as devices constructed to replace missing teeth, and which are supported by surrounding soft and hard tissues of the . Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or . There are two main categories of dentures, depending on whether they are used to replace missing teeth on the or the ., are
Porcelain Veneers can be used to correct a wide variety of cosmetic concerns. Veneers can correct spaces or gaps between teeth, lengthen chipped or worn teeth, and straighten crooked or overlapped teeth making them appear vital and alive.
In , a is a thin layer of material placed over a tooth, either to improve the of a tooth or to protect a damage to a tooth’s surface. There are two main types of material used to fabricate a veneer: and . A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a in a dental laboratory, and later bonded to the tooth, typically using a resin cement such as Panavia. In contrast, a porcelain veneer may only be indirectly fabricated.
Dental implants are replacement tooth roots. Implants provide a strong foundation for fixed (permanent) or removable replacement teeth that are made to match your natural teeth.
Virtually all dental implants placed today are with the titanium post. refers to the fusion of the implant surface with the surrounding bone. Dental implants will fuse with bone; however, they lack the , so they will feel slightly different from natural teeth during chewing., i.e., they appear similar to an actual tooth root (and thus possess a “root-form”) and are placed the bone ( being the Greek prefix for “in” and referring to “bone”). The bone of the jaw accepts and
Prior to the advent of root-form endosseous implants, most implants were either , in that the shape of the metal piece placed within the bone resembled a flat blade, or , in which a framework was constructed to lie upon and was attached with screws to the exposed bone of the jaws.
Dental implants can be used to support a number of dental prostheses, including , or . They can also be used as anchorage for orthodontic tooth movement. The use of dental implants permits undirectional tooth movement without reciprocal action.
Teeth whitening is ideal for people who have healthy, unrestored teeth (no fillings) and gums. Individuals with yellow tones to their teeth respond best. But this cosmetic procedure is not recommended for everyone.
, also known as but most especially in the field of . According to the , restores natural tooth color and whitens beyond the natural color. There are many methods available, such as , bleaching strips, bleaching pen, bleaching gel, laser bleaching, natural bleaching, and swabbing. and , is a common procedure in
Bleaching methods use which reacts with to form . Carbamide peroxide has about a third of the strength of hydrogen peroxide. This means that a 15% solution of carbamide peroxide is the rough equivalent of a 5% solution of hydrogen peroxide. The peroxide penetrates the porosities in the rod-like crystal structure of and bleaches stain deposits in the . Power bleaching uses light energy to accelerate the process of bleaching in a dental office.
