Adhesive dentistry is a branch of dentistry which mainly deals with adhesion or bonding of the adhesive material or cements to the natural substance of teeth, enamel and dentin.
Dental bonding is a dental procedure in which a dentist applies a tooth-colored resin material (a durable plastic material) and cures it with visible, blue light. This ultimately "bonds" the material to the tooth and improves the overall appearance of teeth.
A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth. While inarguably beneficial to dental health, the procedure and materials can be relatively expensive.
A bridge, also known as a fixed partial denture, is a dental restoration used to replace a missing tooth by joining permanently to adjacent teeth or dental implants.
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 indirect method of restoration. However, bridges can be fabricated directly in the mouth using such materials as composite resin.
A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons, including tooth decay that has destroyed enough tooth structure to render the tooth non-restorable. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
Root Canal Treatment
Your dentist will give you an injection of local anaesthetic. This completely blocks pain from the area and you will stay awake during the procedure. You may not need to have an anaesthetic if your tooth is dead. Your dentist will discuss this with you.
Your dentist will separate the affected tooth from the rest of your mouth using a thin sheet of rubber called a dam. This will keep your tooth dry and protect your airways. It also allows your root canal system to be cleaned and stops it becoming contaminated again, which can cause infection later.
Your dentist will make a hole in the top of your tooth, and remove the dead or diseased pulp through this hole. He or she will then clean the empty pulp cavity and may put in some medication to help get rid of bacteria.
This may be all your dentist does at your first visit - if so, he or she will put a temporary filling on your tooth to keep it sealed until you go back for further treatment. However, your dentist may decide to fill the cavity immediately if the root canal infection hasn't caused you any serious problems.
If you had a temporary filling, when you go back to your dentist he or she will remove this and then fill the root canal with a suitable material. This is likely to be a putty-like substance called gutta percha. A permanent filling or crown is then placed over the top of your tooth to protect your filled root canal and your tooth. Your dentist may recommend a crown made from gold or porcelain. If your dentist thinks it's necessary, he or she may also place a metal or plastic rod inside the canal to help support the crown.
Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth, and which are supported by surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, depending on whether they are used to replace missing teeth on the mandibular arch or the maxillary arch.
A dental implant is a "root" device, usually made of titanium, used in dentistry to support restorations that resemble a tooth or group of teeth to replace missing teeth.
Virtually all dental implants placed today are root-form endosseous implants, i.e., they appear similar to an actual tooth root (and thus possess a "root-form") and are placed within the bone (endo- being the Greek prefix for "in" and osseous referring to "bone"). The bone of the jaw accepts and osseointegrates with the titanium post. Osseointegration refers to the fusion of the implant surface with the surrounding bone. Dental implants will fuse with bone, however they lack the periodontal ligament, so they will feel slightly different than natural teeth during chewing.
Prior to the advent of root-form endosseous implants, most implants were either blade endosseous implants, in that the shape of the metal piece placed within the bone resembled a flat blade, or subperiosteal implants, 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 crowns, implant-supported bridges or dentures. They can also be used as anchorage for orthodontic tooth movement. The use of dental implants permits undirectional tooth movement without reciprocal action.
