Dental implants are considered the gold standard in tooth replacement. The reason why they are considered the gold method in replacing teeth is because they restore the most stability and functionality that you can get with false teeth.
Typically the way to replace your teeth in the past was to go down the denture root. This is a removable option that is made to sit on your bone ridges and be held in either by suction (full arch replacements) to precision attachments (partial dentures). There is quite often a bad stigma with dentures as they can be uncomfortable and not well fitting. This happens when the dentures have not been made for your exact measurements of your mouth. Dentures can be very comfortable and this occurs when they are custom made by a skilled dental technician. Over time, due to the missing teeth, it is natural for your mouth to change and therefore your once well fitted dentures are not as comfortable (they will require a reline).
