ORTHODONTIC TREATMENT
This refers to the movement of teeth when they are crowded or in the wrong positions. The problem could be skeletal ie the jaw bones are not big enough to accommodate the teeth and therefore a plate has to be worn in order to expand the jaw bones. If the treatement for expanding the jaw bones is not started early enough and the growth of the child's skeletal bones has been finalised then surgery may be necessary in order to change the structure of the face. This has to be assessed by an orthodontist.
BRACES
This is small brakets glued to each tooth with a wire inserted into these brackets in order to move teeth around the dental arch. There has to be enough space for all the teeth to fit into the dental arch. If there is not enough space then an orthodontic appliance is used to expand the jaws, surgery is also used to expand the jaws or teeth are removed to fit in the dental arch. This has to be assessed by a dentist or orthodontist. Should your child wear braces? This is the preference of the parent, also a financial concern. An assessment is necessary so that any functional problems with the malposition of the teeth can be rectified before any permanent damage is done to either the jaw bones or the teeth.
TEMPRO MANDIBULAR JOINT DISORDERS (TMJ syndromes)
The position of the lower jaw in relation to the skull ie upper jaw, is important and is dependent on the position of the teeth in the jaw bones. If there is malposition of the teeth then the resulting bite could displace the way the lower jaw aligns with the upper jaw and cause problems to the jaw joint. This has to be assessed by a dentist/orthodontist as it could cause headaches/neck ache and other symptoms.
AMALGAM FILLINGS
There is much controversy about the metal/mercury fillings. The scientific community has assessed that the mercury in the fillings is no more dangerous than if you are to eat fish on a regular basis. Removing large amalgam restorations could result in damage to the nerve in a tooth and a need for extensive dental reconstruction. Have your fillings assessed by a dentist. Most modern surgeries today do not use amalgam restorations and use the new modern composite resin fillings.
TYPES OF FILLINGS/RESTORATIONS
Amalgams - rarely used today
Composite resins - recommended for smaller restorations and in the anterior teeth. They can be used in the back teeth to fill in until a crown can be constructed if the destruction of the tooth is too large for a composite filling to repair.
Porcelain inlays/onlays - These are usually for large restorations where the destruction of the tooth is extensive. There is a process called Cerec which is a machine in the dental surgery. A Cerec computer can measure the tooth and the diameter of the preparation and the machine will then construct an inlay/only porcelain restoration while the patient is in the chair. It is about the same cost as if the dentist does the preparation, takes the impression and sends the mould to the technician to prepare in the dental laboratory. It is a merely a measure of convenience.
Gold restorations - are still used today where the bite warrants the use of a strong metal restoration. The preparation is completed and a mould taken and sent to the dental technician.
Glass ionomer restorations - contain fluoride and used mainly for children's primary teeth. Similar to the composite resin restorations but not as strong.
COST OF RESTORATIONS
Varies with dentists but if the restoration is porcelain or gold then laboratory expences escalate the cost up to ten fold.
