Frequently asked questions

When to start and how long is treatment?

In general, active treatment time with orthodontic appliances (braces) ranges from one to three years. Interceptive, or early treatment procedures, may take only a few months. The actual time depends on the growth of the patient’s mouth and face, the cooperation of the patient and the severity of the problem. Mild problems usually require less time, and some individuals respond faster to treatment than others. Use of rubber bands and/or headgear, if prescribed by the orthodontist, contributes to completing treatment as scheduled.

While orthodontic treatment requires a time commitment, patients are rewarded with healthy teeth, proper jaw alignment and a beautiful smile that lasts a lifetime. Teeth and jaws in proper alignment look better, work better, contribute to general physical health and can improve self-confidence.

At what age can people have orthodontic treatment?

Children and adults can both benefit from orthodontics, because healthy teeth can be moved at almost any age. Because monitoring growth and development is crucial to managing some orthodontic problems well, we recommend that all children have an orthodontic screening no later than age 9. Some orthodontic problems may be easier to correct if treated early. Waiting until all the permanent teeth have come in, or until facial growth is nearly complete, may make correction of some problems more difficult.

An orthodontic evaluation at any age is advisable if a parent, family dentist or the patient’s physician has noted a problem.

Orthodontic appliances

Silver Braces Silver braces are the most common type of braces. They are very small these days.

Clear Braces If appearance is important, clear braces are available. Clear braces are often limited to the upper front teeth.

Gold Braces Gold braces are less common.

 

Functional appliances

A “functional appliance” is the name given to an orthodontic appliance that utilizes the muscle action of the patient to move teeth and modify growth. When fitted the functional appliance changes the position of the lower jaw, either holding it open; or open and forward.

Functional appliances are not new. They have been around since the 1920’s although the designs and names have changed. Some functional appliances are removable plates; others are fixed to the teeth. Those used today include the removable Clark Twin Block and Harvold and the fixed Herbst and Mara appliances.

Functional appliances are usually used to treat patients with prominent teeth. In a cooperative, growing patient they reduce the prominence of the teeth by tipping the upper teeth back and the lower teeth forward.

Some practitioners make controversial claims that functional appliances will improve the facial profile by “growing the lower jaw”. There is no scientific evidence to support this claim. However, there is evidence that functional appliances are effective in moving teeth and utilizing the normal growth of the jaws.

Very few patients with prominent front teeth have a good interlocking bite or straight teeth following treatment with just a functional appliance. As a result functional appliances are usually used in conjunction with fixed braces.

While improving the position of prominent teeth, functional appliances will not always eliminate the need for the extraction of permanent teeth in crowded cases, or the need for surgery in cases with a significant difference in the size of the upper and lower jaws.

Advantages of a functional appliance include the immediate improvement in the facial profile when the appliance is fitted. When well worn, the reduction in the prominence of the front teeth occurs early in treatment, providing a psychological boost to the patient. These appliances can also be adapted to fit around baby teeth so treatment can start before all the permanent teeth are through. Removable functional appliances can be taken out making it easier for patients to keep their teeth clean.

There are, however, significant disadvantages associated with the use of functional appliances. The bulky design of some functional appliances can interfere with speech and eating. If the appliance is removable then there are significant demands on the patient to wear the appliance. The temptation to remove it can be great, and if removed there is a lack of progress and it is likely the plate will be lost or broken, adding to the cost of treatment.

There are many ways to move teeth and correct a bad bite. Despite claims to the contrary, functional appliances are not in anyway superior to, more efficient than or cheaper than conventional fixed braces. Orthodontists have training in the use of both fixed braces and functional appliances and will choose the most appropriate appliances for each individual orthodontic problem.

Caring for teeth and gums

How do I keep my teeth and gums healthy?
The key to healthy teeth and gums is proper plaque removal every day. Plaque is the sticky colourless film of bacteria that is constantly forming on your teeth. If it is left to build up, it is one of the main causes of tooth decay and gum disease.

Follow these simple instructions and you'll be off to a great start:

• Brush your teeth, gums and braces at least three times a day (and especially after eating)
• Clean between the teeth at least once daily - and definitely before you go to bed
• Use a fluoride toothpaste - fluoride is proven to help prevent cavities
• Use a fluoride mouth rinse at least once daily to help reduce the risk of cavities

Try to carry your toothbrush and floss with you at all times do that you can clean your teeth even when you are not at home

How do I clean all areas of my mouth while wearing braces?

At first, doing a good job removing plaque from your teeth and along the gum line may seem difficult with braces. But keep at it - with a bit of practice it will get easier! Following these tips will also help:

• First, take off any removable parts like elastic bands and headgear
• Place your gum at an angle of about 45 degrees to the gum and apply gentle pressure as you brush with a gentle back and forward, up and down, or round and round motion. Clean each tooth individually for about 10 seconds
• Use the same brushing motion on the inner and outer surface of all teeth
• Don't forget to brush the chewing surfaces of your teeth - and make sure you reach the back teeth too
• Finish by cleaning around your braces, brushing first from the top and then from the bottom. Brush gently and take care not to bend or break any of the brackets or wires

How often should I clean my braces?

It is vital that you clean your braces every time you brush your teeth. Braces can act as a "plaque trap", increasing the amount of plaque on your teeth, which in turn can lead to an increased risk of caries and gum disease.

How do I floss with fixed braces?

Flossing removes the plaque between your teeth and under your gum line - areas beyond the reach of your toothbrush. In fact, if you don't floss, you're leaving up to 40% of your tooth surfaces untouched and uncleaned.

Choose a floss (such as “Super floss”) with a stiffened end that threads it through the gap between each tooth - above the wire for your upper teeth and below the wire for your lower teeth.

Curve the floss around each tooth in a "C" shape and gently move it up and down the side of each tooth, including under the gum line. Unroll a new section of floss as you move from tooth to tooth.

Common problems

Orthodontic emergencies do occur occasionally and, although they may be a little upsetting for the patient and parents, they are actually fairly simple to treat.

For some emergencies, you may need to contact your orthodontist.

To help you accurately describe an emergency situation to your orthodontist, use the diagram below, which illustrates and names each part of a typical set of braces.

A. Ligature
The archwire is held to each bracket with a ligature, which can be either a tiny elastic or a twisted wire.

B. Archwire
The archwire is tied to all of the brackets and creates force to move teeth into proper alignment.

C. Brackets
Brackets are connected to the bands, or directly bonded on the teeth, and hold the archwire in place.

D. Metal Band
The band is the cemented ring of metal which wraps around the tooth.

E. Elastic Hooks & Rubber Bands
Elastic hooks are used for the attachment of rubber bands, which help move teeth toward their final position.

Tools & Supplies
With these tools and supplies on hand (most of which you will already have), you will be prepared to handle the most common orthodontic emergencies.

• Non-medicated orthodontic relief wax
• Dental floss
• Sterile tweezers
• Small, sharp clipper
• Salt
• Interproximal brush
• Toothpicks
• Non-prescription pain reliever
• Topical Anaesthetic (such as Orabase or Ora-Gel)

Emergency Treatments
The following orthodontic emergencies and their treatments are listed in the order of the least severe to the most severe. Only the most severe emergencies will require immediate attention by an orthodontist or medical doctor. The majority of these are easily treated with a follow-up by the patient’s orthodontist.

Food Caught Between Teeth
This is not an emergency, but can be a little uncomfortable or embarrassing for the patient. It is easily fixed with a piece of dental floss or use an interproximal brush or toothpick to dislodge food caught between teeth and braces.

Lost Wire or Ligature
Tiny rubber bands or small, fine wires, known as ligatures, hold the wire to the bracket. If a rubber or wire ligature is lost, notify the orthodontist who will advise whether the patient should be seen.

Ligatures Come Off
If a rubber ligature should come off, you may be able to put it back in place using sterile tweezers. If a wire ligature comes loose, simply remove it with sterile tweezers. If the wire ligature is sticking out into the lip but is not loose, it may be bent back down to eliminate the irritation.

Of course, when one ligature pops off or breaks, others may follow. Missing or broken ligatures should be brought to the attention of the orthodontist.

Discomfort
It’s normal for a patient to have discomfort for a day or two after braces or retainers are adjusted. But it can make eating uncomfortable. Reassure the patient that the discomfort is both normal and temporary. Encourage soft foods. Have the patient rinse the mouth with warm salt water. If the patient is allowed to have over-the-counter pain relievers, these may be effective.

Mouth Sores
Some patients are susceptible to episodes of mouth sores. While braces do not cause them, they may be precipitated or exacerbated by an irritation from braces. One or several areas of ulceration of the cheeks, lips or tongue may appear. This is not an emergency, but may be very uncomfortable for the patient. Prompt relief may be achieved by applying a small amount of topical anaesthetic (such as Orabase or Ora-Gel) directly to the ulcerated surface using a cotton swab. Instruct the patient to reapply as needed.

Irritation of Lips or Cheeks
Sometimes new braces can be irritating to the mouth, especially when the patient is eating. A small amount of non-medicinal relief wax makes an excellent buffer between metal and mouth. Simply pinch off a small piece and roll it into a ball the size of a small pea. Flatten the ball and place it completely over the area of the braces causing irritation. The patient may then eat lunch more comfortably. Let the patient know that if the wax is accidentally ingested it’s not a problem. The wax is harmless.

Protruding Wire
Occasionally the end of a wire will work itself out of place and irritate the patient’s mouth. Use a suitable implement to push the wire so that it is flat against the tooth. If the wire cannot be moved into a comfortable position, cover it with relief wax. (See Irritation of Cheeks or Lips above for instructions on applying relief wax.) The orthodontist should be notified of the problem.

In a situation where the wire is extremely bothersome and the patient will not be able to see the orthodontist anytime soon, as a last resort, you may clip the wire.

Reduce the possibility of the patient swallowing the snipped piece of wire by using folded tissue or gauze around the area. Use a pair of sharp clippers and snip off the protruding wire. Relief wax may still be necessary to provide comfort to the irritated area.

Loose Brackets, Wires or Bands
If the braces have come loose in any way, the orthodontist should be notified.

A Bracket is Knocked Off
Brackets are the parts of braces attached to teeth with a special adhesive. They are generally positioned in the centre of each tooth. The bracket can be knocked off if the patient has eaten one of those hard or crunchy foods orthodontic patients are instructed to avoid, or if the mouth is struck while at play. (Encourage the patient, especially if he or she is wearing braces, to wear a protective mouth guard while playing sports.)

If the bracket is off centre, the adhesive may have failed. Notify the orthodontist, who will determine the course of action.

If the loose bracket has rotated on the wire and is sticking out, and the patient cannot immediately be taken to the orthodontist, you can do a temporary fix to alleviate discomfort and prevent further damage. But take care to prevent swallowing or other injury.

To put the bracket back in place, use sterile tweezers to slide the bracket along the wire until it is between two teeth. Rotate the bracket back to the proper position, then slide it back to the centre of the tooth.

Piece of the Appliance is Swallowed or Aspirated
This is rare, but when it does happen, it can be fairly alarming to the patient. Encourage the patient to remain calm. If the patient is coughing excessively or having difficulty breathing, the piece could have been aspirated. If you are able to see the piece, you may carefully attempt to remove it. But do not make the attempt if you would cause harm.

If there is no coughing or difficulty in breathing, call the appropriate emergency number for your area for advice or instructions and notify the orthodontist.

If appropriate under the circumstances, examine the patient’s braces for problems that may result from the missing piece, such as looseness or irritation, and treat as specified above.

If you are unable to see the piece and believe it may be have been aspirated, call the appropriate emergency number for your area, then notify the parents and the orthodontist immediately. The patient should be taken to an urgent care facility for an x-ray to determine the location of the piece. A physician will have to determine the best way to remove it.

Surgical procedures

Some types of malocclusions are not able to be corrected solely with braces and require a combined approach of surgery and orthodontics. This is often the case with adults as adult facial bones are no longer growing.

Risks

As with any medical treatment there are some risks and limitations to orthodontics. It is important to consider these when making the decision to undergo treatment.

Fortunately with orthodontic treatment complications are infrequent and if they do occur are usually minor.

What will it cost?

Orthodontic fees vary widely, depending on the severity of the problem, complexity of treatment and length of treatment time.

Orthodontists routinely discuss fee arrangements after individual examinations. Generally, fees may be paid over extended periods during the course of treatment.
