Orthodontics / Braces
The sad fact is, 10 years after completion of orthodontic treatment, only 30-50% of patients retain satisfactory teeth alignment1. After 20 years, this further drops to only 10% of patients1. While most changes to teeth alignment are due to late jaw changes between the ages of 20-30 years, tooth movement and crowding can still continue in your 50's or 60's2.
Crooked teeth can also affect your oral health - when teeth overlap, they can wear down unevenly and are harder to keep clean. Plaque and tartar build up faster, which leads to gum infections such as gingivitis and periodontitis.
