Yes. When teeth are missing, the teeth on each side of the space will tend to drift into the empty space. This can create a number of problems. First of all, these spaces between the teeth are unattractive and can detract from your smile. Additionally, tipping of the teeth can lead to problems with function and recession of the gum tissue. Orthodontic treatment will correct and prevent these problems and will also provide proper alignment for your dentist to replace the missing teeth.
