Example 1
This lady has teeth that look straight but her teeth do not meet and she does not like her facial appearance, especially her profile.

She now has major jaw joint, head and neck pain. 

She requires a considerable amount of physical therapy and medications (etc) and she also requires complex braces and jaw surgery to correct her bite. 

She should have had facial and bite adjustments delivered by Damon Braces at around 12 years of age. 

Unfortunately, it is too late now for "easy treatment". The moral is "do not delay"!

Example 2
This is what happens when teeth do not meet correctly. This is called class II with deep vertical overlap.

The teeth get "patched" with crowns, fillings, etc., but eventually fail with severe wear on natural teeth.  Now major orthodontics and advanced restorative dentistry is needed.

This all could have been prevented by correctly executed orthodontic treatment at around age 11 or 12. The moral is "do not delay"!
