What is a Dental Bridge?
In simple terms, a dental bridge replaces missing teeth; it consists of crowns and artificial teeth. A dental bridge can replace one tooth or a row of missing teeth. There are a few different parts that make up a dental bridge: abutments and pontics.
Abutments are small screws that support the dental crowns. They provide stability and support to the crown and are custom to the crown’s position, allowing for better aesthetics. Abutments take about 4-6 weeks to heal, and it is very important to follow your surgeon’s instructions to ensure they heal properly. There are three types of abutments: prefabricated, titanium, and zirconium. Prefabricated abutments are made in different shapes and sizes based on what the patient needs. Often they are made from stainless steel, zirconium, and titanium. Titanium abutments are considered the “gold standard” for abutments because they are very strong, durable, and biocompatible. Zirconium abutments are an alternative to titanium dental implants. They are known for their high resistance to cracking and are designed to be long-lasting. Zirconium abutments are considered to be more durable than titanium.
Pontics are artificial teeth that replace missing teeth, and they are designed to address the different needs as well as preferences of the patient. There are four different types of pontics commonly used: traditional, cantilever, Maryland, and implant-supported.
- Traditional: This type of pontic is the most common and is attached to the crown, replacing the missing tooth. They can be made of various materials such as metal or porcelain.
- Cantilever: This pontic is designed for a patient who has only one healthy tooth next to the missing tooth. Therefore, this pontic extends from the crowned tooth, putting much more stress on it. Because of this, it is less common than a traditional pontic.
- Maryland: A Maryland pontic does not require crowns on the nearest healthy teeth. Instead, there are two small wings on the tooth that are bonded to the two outside healthy teeth.
- Implant-Supported: This is the most stable and long-lasting option. The dental implant is surgically placed into the jawbone, acting as an artificial root. It provides tremendous support and prevents bone loss.
There are a few factors that the dentist will consider to determine what type of bridge you require. They include, but are not limited to: age, number of missing teeth, size of gap, the condition of the surrounding teeth, whether or not you have natural teeth on both sides of the gap, overall gum health, overall tooth health, and your personal preferences.
Like many surgical operations, there are pros and cons. Dental bridges can provide a natural-looking solution for tooth loss, and they can restore chewing abilities and speech function. With that being said, they can decay if trauma in the area persists, and can weaken the overall dental bridge. Additionally, if your natural teeth are not strong enough to support the bridge, they can fracture.
If you are missing one or more teeth, a dental bridge could be a great option to fill the missing gap in your smile and improve your ability to chew and speak properly. Contact your dentist today for more information about replacement options that best fit your needs, preferences, and budget.
