As your back teeth wear down, your lower jaw has tendency to come forward. This is a sure sign it’s time for new dentures. The American Dental Association recommends replacing your dentures every 5 to 7 years.

If your bite is “Class 1,” or normal, having new dentures made will correct this problem.  However, some people are born with this jaw relationship called a “Class 3” bite, where the chin and lower lip protrude. We can make some improvements cosmetically by setting teeth in a way which softens the appearance of an under-bite.

If an under-bite is too great, we may choose to make a “treatment” lower denture, which gradually allows your jaw to get accustomed to the difference in height.
