However, most retainers simply do what their name implies: they retain the teeth in their present positions. Even if the teeth are not perfect and orthodontic treatment is not desired, retainers can be used to stop the shifting in its tracks.
Retainers are very important to hold the teeth after braces and it is best if they are made a life-long priority. As your orthodontist in Melbourne, we usually recommend retainers to be worn close to full-time for a period of six months after braces are removed so the teeth can stabilize in their new positions. After this period we recommend retainer wear every night. Teeth will change throughout life unless something is done to hold them in position. Some people are very lucky and changes are only minimal over a long period of time and some people’s teeth can shift quickly. It is impossible to predict how fast they will move. They can move even if wisdom teeth are missing or extracted.
There are three types of retainers most commonly used: hard plastic and wire (Hawley) retainers, clear soft plastic retainers, and fixed (permanent) retainers. We believe strongly in the Hawley retainers primarily because of the drawbacks of the other types.
The clear plastic retainers fit around all surfaces of the teeth like a bleaching tray. They do not allow upper and lower teeth to contact each other and the molar areas can be worn through pretty quickly due to grinding, so they usually need to be replaced periodically. They are much cheaper to produce than Hawley retainers, although most orthodontists charge similar fees for them.
The most commonly used fixed retainers are wires glued to the insides of each of the lower six front teeth. If one of the glued areas comes loose, it may not be noticed until that tooth has moved. The bite will usually not allow one of these types of retainers to be placed in the upper arch. The tongue side of the lower front teeth has the highest accumulation of plaque and tartar in the mouth, and it is where your hygienist will usually spend the most time cleaning. Having something glued here makes this area even more difficult to keep clean and floss and therefore it can increase risk for periodontal disease and cavities.
Hawley retainers are removable to allow for good hygiene and they can last a lifetime if properly cared for. Everyone that works in our office has this type of retainer.
We are now welcoming patients and parents into our waiting rooms. There is no need to call us when you arrive. We are, however, asking that everyone wear face coverings upon entering, regardless of vaccination status. We continue to take precautions for prevention of spreading COVID-19. We remain vigilant with our sterilization and disinfection protocols and we will continue taking additional precautionary measures as well. We still ask that you reschedule your appointments if the patient has been symptomatic in the last ten days or has been recently exposed to someone known to be infected with COVID-19.
We will continue utilizing only half of our operatories to maintain significant distance between patients. We ask that all of our patients thoroughly brush their teeth prior to their appointments to limit the use of our toothbrushing area. As always, we will continue to be committed to giving each of our patients the best possible experience!
Thank you for your understanding!
