The American Association of Orthodontists recommends that all children see an orthodontist by at least age seven and sooner if something is obviously wrong before age seven. Fortunately, most young patients don't need anything more than observation while the permanent teeth are growing into place.

Many young patients have problems, which will not, or should not wait. Most orthodontic problems are inherited and cannot be totally prevented; however something can usually be done before these problems become more difficult and more expensive to manage.

It is advisable to consult with an orthodontist prior to having your dentist remove any baby teeth or permanent teeth. To ensure the best overall dental and facial development, all patients should have an orthodontic consultation sometime between the ages of four and seven.

Classifications of Teeth

The classification of bites is divided into three main categories: Class I, II, and III. This classification refers to the position of the first molars, and how they fit together.

Class I
Class I is a normal relationship between the upper teeth, lower teeth and jaws or balanced bite.


Class I normal



Class I crowding

 

Class I spacing
 

 

Class II
Class II is where the lower first molar is posterior (or more towards the back of the mouth) than the upper first molar. In this abnormal relationship, the upper front teeth and jaw project further forward than the lower teeth and jaw. There is a convex appearance in profile with a receding chin and lower lip. Class II problems can be due to insufficient growth of the lower jaw, an over growth of the upper jaw or a combination of the two. In many cases, Class II problems are genetically inherited and can be aggravated by environmental factors such as finger sucking. Class II problems are treated via growth redirection to bring the upper teeth, lower teeth and jaws into harmony.

Class III
Class III is where the lower first molar is anterior (or more towards the front of the mouth) than the upper first molar. In this abnormal relationship, the lower teeth and jaw project further forward than the upper teeth and jaws. There is a concave appearance in profile with a prominent chin. Class III problems are usually due to an overgrowth in the lower jaw, undergrowth of the upper jaw or a combination of the two. Like Class II problems, they can be genetically inherited. Class III problems are usually treated via surgical correction of one or both jaws.

 
Class III functional or dental

 
 
Class III skeletal

 

 

Orthodontic Problems

 
Overjet
Upper front teeth protrude


 
 
Deep bite
Upper front teeth cover lower front teeth too much

 
 
Underbite

Back teeth are together with space between the front teeth


 

Crowding
Upper and/or lower teeth are crowded


 

Excess Spacing
There is excess space between teeth


 

Mid-Line Misalignment
Mid-lines of upper and lower arches do not line up

 

Crossbite
Upper back teeth fit inside lower teeth

Phases of Treatment

Phase I: Treatment usually takes 12 to 18 months and is done between the ages of 7-9. A variety of appliances may be used to correct specific problems.

Maintenance / Recall Phase: During the time between the first and second phase the patient will be seen every few months per year. This is to monitor the eruption of the permanent teeth and exfoliation of primary teeth.

Phase II (if required): During the first phase of treatment Dr. Bock has no control over 16 unerupted permanent teeth. If they grow in and problems still exist, further treatment, known as Phase II, will be required. A separate fee will be quoted at that time. Treatment usually takes 12-24 months.

Full Treatment: If you decide to wait, treatment will be started when all permanent teeth have erupted. Full treatment usually takes 18-30 months. The length of treatment depends on the severity of malocclusion and orthodontic problems.

Proper Braces Care and Brushing Techniques

Brushing and flossing your teeth can be challenging when wearing braces but it is extremely important that you do both consistently and thoroughly.

 
 
 


Foods to Avoid During Treatment: Eating proper foods and minimizing sugar intake are essential during orthodontic treatment. Your braces can be damaged by eating hard, sticky, and chewy foods.

  • Hard foods : Nuts, Candy, Hard Pretzels
  • Crunchy foods : Popcorn, Ice, Chips, etc.
  • Sticky foods : Gum, Chewy Candy (Skittles, Taffy, Gummy Bears, Caramel, etc.)
  • Chewy foods : Bagels, Hard Rolls, etc.
  • Foods you have to bite into : Corn on the Cob, Apples, Carrots (cut these foods up into smaller pieces and chew on back teeth)
  • Chewing on Hard Objects (for example, pens, pencils or fingernails) can damage the braces. Damaged braces will cause treatment to take longer.

Child sucking thumb.

Is there any image that illustrates the comforts of babyhood better than a sleepy infant sucking his or her thumb? Ultrasound pictures have shown, to the joy of many prospective parents, that this behavior can even occur in the womb. The thumb- or finger-sucking habit seems to relax and comfort toddlers too, and it's perfectly natural. But as a child grows, there comes a point where this habit isn't just socially awkward — it may also be harmful to his or her oral health.

In most children, thumb sucking stops on its own between the ages of two and four years. But if the practice persists after the primary (baby) teeth have erupted, it can drastically change the growth patterns of the jaw, and cause significant misalignment of the teeth. It may be hard to believe that such a benign habit can actually move teeth and bone — but there are a number of reasons why this occurs.

Children's jaws, rich in blood supply and growing rapidly, are relatively soft and flexible — especially in kids under the age of 8. So it really isn't hard for the constant pressure of a thumb or finger to deform the soft bone around the upper and lower front teeth. Children who are particularly vigorous thumb suckers are even more likely to change the growth patterns of the teeth and jaws.

If the thumb sucking habit persists, it can result in the upper front teeth flaring out and the lower ones moving back and inward. It can also hold back the growth of the lower jaw, while causing the upper jaw to be thrust forward. This can result in misalignment of the teeth, an anterior open bite (where the front teeth fail to close together), collapse of the upper jaw causing crossbite, or other problems. That's why it is important to stop the behavior at an appropriate time, before damage occurs.

Controlling Thumb or Finger Sucking

Like many potentially harmful behavior patterns, thumb sucking can be a difficult habit to break. Through the years, parents have tried a variety of home remedies, such as having the child wear gloves, coating the digits with a bitter-tasting substance — and even reasoning with their toddlers. Sometimes it works — but in other cases, the allure of thumb sucking proves very difficult to control.

Fixed palatal crib.

If your child has a thumb or finger sucking habit that has persisted past the age of 3, and you've been unable to tame it, then it may be time for you to visit the dental office for a consultation. A “habit appliance” such as a fixed palatal crib or a removable device may be recommended for your child. This crib isn't for sleeping — it's a small metal appliance worn inside the mouth, attached to the upper teeth.

How does it work? The semicircular wires of a palatal crib keep the thumb or finger from touching the gums behind the front teeth. Simply preventing this contact seems to take all the enjoyment away from the thumb sucking habit — and without that pleasurable feedback, a child has no reason to continue the behavior. In fact, the device is often successful the first day it's worn.

Getting and Using a Habit Appliance

If your child could benefit from a habit appliance, the first step is to get a thorough examination, which may include taking x-rays, photographs and dental impressions. If it's recommended, a crib will then be custom-fabricated to fit your child's mouth, and placed at a subsequent appointment. Afterwards, your child will be periodically monitored until the appliance is removed — typically, a period of months.

Although wearing the crib isn't painful, your child may experience some soreness in the upper back teeth for a few hours after it's first installed. He or she may also have a little trouble falling asleep for a day or two afterward. Plenty of extra attention and TLC are usually all that's needed to make everything all right. While the appliance is being worn, it's best to avoid chewing gum and eating hard, sticky food that might cause it to come loose.

A Word About Tongue Thrusting

Like thumb sucking, tongue thrusting is a normal behavioral pattern in young children. It's actually part of the natural infantile swallowing pattern, which will normally change on its own — by the age of six, in most children. If the pattern doesn't change, however, it can lead to problems similar to those caused by thumb sucking: namely, problems with tooth alignment and skeletal development. Fortunately, this problem can be successfully treated with a habit appliance that's very similar to a fixed palatal crib.

How Thumb Sucking Affects The Bite Thumb sucking can actually block the front teeth from erupting fully and can also push the teeth forward — sometimes more on the side where the thumb rested. How far out of position the teeth end up will depend on the number of hours per day the thumb was in the child's mouth and how much pressure was applied. When the pressure exerted by the thumb in the mouth is particularly strong and occurs over a long period of time, the forces can potentially influence growth of the jaws... Read Article
