Missing teeth can make a real difference in your daily life, limiting your diet choices and/or affecting your social life. Teeth are lost for a variety of reasons, such as trauma, injury, gum disease, or illness. Missing teeth can and should be replaced. Each and every gap in your teeth poses potential problems for your long term dental health. One missing tooth can lead to additional tooth loss and ultimately a change in facial appearance. Long term changes, such as tooth migration into the gap, causes additional gum problems and bite problems, possibly triggering TMJ pain and lastly loss of jaw bone.
