Deals primarily with malpositioned teeth and the jaws: their diagnosis, prevention and correction.
Orthodontic treatment is a way of straightening or moving teeth, to improve the appearance of the teeth and how they work. It can also help to look after the long-term health of your teeth, gums and jaw joints, by spreading the biting pressure over all your teeth.
Many people have crowded or crooked teeth. Orthodontic treatment will straighten the teeth or move them into a better position. This can improve their appearance and the way the teeth bite together, while also making them easier to clean.
Some people have upper front teeth that stick out and look unsightly. These ‘prominent’ teeth are more likely to be damaged, but orthodontic treatment can move them back into line. Or the way the upper and lower jaws meet can cause teeth to look unsightly and lead to an incorrect bite. Orthodontic treatment may be able to correct both of these problems.
When the teeth don’t meet correctly, this can put strain on the muscles of the jaw, causing jaw and joint problems and sometimes headaches. Orthodontic treatment can help you to bite more evenly and reduce the strain.
The best time is generally during childhood, but adults can have orthodontic treatment too – and more and more are doing so. Age is less important than having the right number of teeth. In children it may be necessary to wait for enough teeth to come through before starting treatment.
The most important thing is to have a full examination. This will usually involve looking at your teeth, taking x-rays and making plaster models of your teeth.
Your dental team or orthodontist will then discuss what treatment is possible. Once you are sure you want to go ahead, the treatment can start as soon as you have enough permanent teeth.
Often a fixed brace is used. This has brackets and bands which are temporarily stuck to the teeth. A flexible wire joins all the brackets and allows the teeth to be moved. You can’t take the appliance out yourself, so it is called a fixed appliance.
Another popular option is the invisible braces, commonly named Invisalign, a tough, clear plastic ‘aligners’ (moulds) that are used to straighten teeth. Several sets of specially moulded, slightly different aligners are made for each patient. Each set is worn for a few weeks before being replaced with the next one. They are made from clear plastic, so they are nearly invisible. This means that no one need know you are straightening your teeth.
The aligners should be worn for 22 to 23 hours a day for the best results. They can be easily removed for eating, drinking, brushing, and for cleaning in between your teeth.
The length of treatment depends on how severe the problem is, and it may take anything from a few months to two-and-a-half years. Most people can be treated in one to two years.
When treatment is finished the teeth need to be held in position for a time. This is called the ‘retention’ period, and the appliances that hold the teeth in place are called retainers.
The retainers hold newly straightened teeth in position while the surrounding gum and bone settles. The retainers can be removable or fixed, depending on the original problem.
Occasionally the mouth may not have enough room for all permanent teeth. If so, you may need to have some permanent teeth taken out to make space. The Dentist will tell you whether this is the case. Sometimes space can be made using other forms of treatment.
