When you have a single tooth missing, your dentist will replace it with a tooth implant. It will be covered with a crown to protect the implant from decay and wear and tear.
However, when you have more than one adjacent teeth missing, your dentist will replace them with implants and cover the top with a bridge as installing a crown won’t be possible.
When your dentist installs restorations, they won’t be visible as they are natural-looking. They are made from porcelain and they match patient’s teeth color.
To install a crown when a single tooth is missing, your dentist will place a titanium rod after drilling a hole in the bone. An abutment is placed at top of the rod before attaching a crown. Due to the multiple steps involved in this procedure, you may have to visit your dental office 3 times in most cases.
On the other hand, when you have more than one teeth missing, your dentist will place a bridge to hold several teeth as a group of crowns anchored together. Like individual tooth, titanium rods are inserted in the bone after drilling holes through them. However, the holes don’t have to be drilled through each tooth in such cases. Your dentist will make hole through two teeth to hold together crowns for three to four teeth and so on.
Drilling holes through each tooth can be costly and it can also make the procedure lengthy. In addition, it doesn’t provide extra strength. Even with holes through couple of teeth, your implants will be strong enough to support the biting force of several teeth.
