Orthodontic treatment promotes a healthy smile, healthier teeth and gums and a better bite for normal chewing.
Orthodontic treatment depends for much of its success on the understanding and co-operation of the patient. This form covers the usual material risks associated with orthodontic treatment. Other factors may also be described by your orthodontist. You may ask your orthodontist to explain anything you do not understand. While recognising the benefits of healthy teeth and a pleasing smile, you should also be aware that orthodontic treatment has limitations and potential risks and there maybe alternative treatment options. You should clarify what is expected of you as a patient, or as the parent of a young patient, to achieve excellent results. Keep in mind that with orthodontic treatment, like other healing arts, the results cannot be guaranteed. The unknown factor in any orthodontic corrections is the response of the patient to the orthodontic treatment.
Should you have any questions, please ask.
Orthodontics plays an important role in improving overall oral health and achieving balance and harmony between the face and teeth for a healthy smile, which may enhance one’s self esteem. The correct bite of the teeth with healthy muscles and jaw joints will provide optimal chewing function. Properly aligned teeth are easier to brush and so the tendency to decay may be decreased, as may the likelihood of developing disease of the gums and supporting bone. Correctly aligned teeth are less likely to experience abnormal wear.
Because of the individual conditions present and the limitations of treatment imposed by nature, each specific benefit may not be attainable for every patient.
All forms of medical and dental treatment, including orthodontics, have some risks and limitations. Fortunately, in orthodontics complications are infrequent and when they do occur, they are usually of only minor consequence. Nevertheless, they should be considered when making the decision to undergo orthodontic treatment. The principal risks in orthodontic treatment pertain to:
- Oral Hygiene
Orthodontic appliances do not cause tooth decay. Gum disease, tooth decay and permanent markings (decalcification) on the teeth can occur if orthodontic patients eat food containing excessive sugar or do not brush their teeth frequently or properly. These same problems can occur without orthodontic treatment, but the risk is greater to an individual wearing braces.
It is imperative during orthodontic treatment that extra care be taken with oral hygiene and tooth brushing in particular.
Teeth may have a tendency to change their positions after treatment. The long-term, faithful wearing of retainers should reduce this tendency. Teeth can, however, move any time, whether or not they have had orthodontic treatment. This is especially true during the late teen period when active growth of the facial bones is coming to an end. The most vulnerable teeth are those at the front. Throughout life the bite can change adversely from various causes such as eruption of wisdom teeth, growth or maturational changes, mouth breathing, playing of musical instruments and other oral habits. Very occasionally, tooth movements will be severe enough to merit a further course of treatment to ensure a satisfactory result.
- Periodontal Health
The health of the bone and gums which support the teeth may be affected by orthodontic tooth movement if a condition already exists, and in some rare cases where a condition does not appear to exist. In general, orthodontic treatment lessens the possibility of tooth loss or gum infection due to misalignment of the teeth or jaws. Inflammation of the gums and loss of supporting bone can occur if bacterial plaque is not removed daily with good oral hygiene.
- Root Shortening
In some patients, the length of the roots of the teeth may be shortened during orthodontic treatment. Some patients are prone to this happening, some are not. It is nearly impossible to predict susceptibility. Usually this shortening does not have significant consequences, but on very rare occasions it may become a threat to the longevity of the teeth involved.
- Jaw Joints
Occasionally, patients may suffer pain or dysfunction in the jaw joints (TMJ). This may present as joint pain, headaches or ear problems. These problems may occur with or without orthodontic treatment. Any of the above noted symptoms should be reported to the orthodontist. Some patients are susceptible to TMJ problems and some are not. Numerous studies have shown that the movement of the teeth during orthodontic treatment is unrelated to the onset of TMJ problems. Just as for painful conditions in other joints, discomfort in TMJ can last from a few days to several weeks or longer.
- Tooth Vitality
Sometimes a tooth may have been traumatised by a previous accident or a tooth may be decayed or have fillings which can cause damage to the nerve of the tooth. Orthodontic tooth movement in some cases aggravates this condition and in rare instances, may lead to loss of tooth vitality and discolouration of the tooth requiring root canal treatment and other dental treatment to restore the colour of the tooth.
- Loose Appliances and Discomfort
The gums, cheeks or lips may be scratched or irritated by newly placed appliances or by loose or broken appliance or by blows to the mouth. You will be given instructions on minimising these affects. Very rarely loose orthodontic appliances may be accidentally swallowed or aspirated. You should inform your orthodontist of any unusual symptoms, or broken or loose appliances, as soon as they are noted. Usual post adjustment tenderness should be expected, and the period of tenderness or sensitivity varies with each patient and the procedure performed. (Typical post adjustment tenderness may last 24 to 48 hours)
- Atypical Growth
Insufficient excessive or asymmetrical changes in the growth of the jaws may limit the orthodontist’s ability to achieve the desired result. If growth becomes disproportionate during orthodontic management, the treatment may be prolonged. Growth changes that occur after orthodontic treatment may alter the quality of treatment results and may require further orthodontic treatment. In some cases of atypical growth, the bite may change so much that oral surgery is required to achieve the best possible result.
If improperly handled, headgear may cause injury to the face. Patients are warned not to wear the appliance during times of boisterous or competitive activity.
- Treatment Time
The total time required to complete treatment may exceed the estimate. Poor co-operation in wearing the appliance or the elastics for the required hours per day, poor oral hygiene, broken appliances and missed appointments can lengthen the treatment time and affect the quality of the results.
Co-operation throughout treatment is your best guarantee of achieving a pleasing smile and a good bite. Failure to co-operate could force the orthodontist to change the procedures and goals of our treatment. As a last resort, treatment may have to be suspended. The consequences of early suspension may be worse than no treatment at all.
- Complementary Aesthetic Dentistry
If your teeth vary from normal in the number, size or shape of the teeth, achievement of the ideal result (for example, complete closure of the excessive space) may require restorative treatment. The most common types of complementary treatment are cosmetic bonding, crown and bridge restorative dental care and periodontal therapy.
- General Health
General medical problems can affect orthodontic treatment. You should keep your orthodontist informed of any changes to your medical health.
- Dark Spaces
Near the gum, teeth that are rotated are difficult to keep clean. Often once the teeth have been straightened in adults, we see that small dark spaces near the gum can develop.
We can often reduce these spaces by polishing the teeth, but due to long-term bone loss from an inability to brush well, these dark spaces may still be present at the completion of treatment. It is important patients know this prior to the commencement of orthodontic treatment.
