Why Early Treatment?

While there is no exact age for children to begin orthodontic treatment, the American Association of Orthodontists recommends visiting the orthodontist around age seven.

By this age, most children have a mix of baby teeth and adult teeth, making it easier for the orthodontist to diagnose and correct tooth and jaw problems sooner and without surgery.



  • Correct and guide the growth of your child’s jaw to help the permanent teeth come in straight
  • Regulate the width of the upper and lower arches
  • Create more space for crowded teeth
  • Avoid the need for permanent tooth extractions later in life
  • Correct thumb sucking and help improve minor speech problems

  • If traditional braces are just not for you, it may be time to get Invisalign in Bristol. The convenience of the Invisalign removable aligners gives you the freedom to eat what you want and makes it much easier to brush and floss. Since the aligners are transparent, you can see unobstructed progress on your teeth as they straighten. Dr. Wood is an Invisalign Premier Elite Provider, meaning you won’t find anyone in the Tri-Cities area more experienced in this treatment.


  • No matter your age, you can get braces in Bristol. Orthodontics for younger kids allows the doctor to diagnose potential problems and apply corrective actions to prevent them from being an even bigger issue as they grow. By the age of seven, Dr. Wood can start to correct thumb-sucking, arch width, and jaw alignment so that permanent teeth can grow correctly
  • Teens will be excited to know that they can add some of their personal styles to their visible braces with a choice of materials and colors, and, in some cases, we may be able to apply lingual or behind-the-teeth braces. For our adult patients, we have several options to fit your needs, preferences, and lifestyle:
  1. Clear or invisible braces
  2. Ceramic or traditional metal braces
  3. Lingual braces
  4. Self-ligating braces (no elastic or metal ties)


  • Orthodontics focus on managing the alignment of teeth. In dentofacial orthopedics, the growth and alignment of the jaw and facial bones help with the straitening of teeth. You may be familiar with some dentofacial appliances, such as expanders or headgear, that are used before or during treatment with braces. These types of treatments are typically used for children to adolescents.
