A diagram of dental implant at Periodontal Associates. Dental implants are a highly effective solution for lost teeth. Crowns mimic natural teeth in their form and function and titanium posts bond with and stimulate your jaw bone, allowing the implants to act just like a natural tooth would.

Unfortunately, implants can occasionally fail, and if this happens we will need you to come in so we can repair or replace them.

The Structure of an Implant


Most dental implants are made of a titanium post that is embedded in the jaw bone, a ceramic crown that acts as a replacement tooth and an abutment that connects the post and the crown. If one of these parts loosens or breaks, all three can become compromised.

Titanium is usually chosen for implants because it bonds with the jaw bone in a process known as osseointegration. If this process doesn't occur properly then you'll end up with an implant that isn't firmly in place. This will lead to problems later on.

Signs that an Implant May Fail


If the bone doesn't grow around the implant in the right way, mobility is often the primary signal that the implant may fail. This mobility is often very slight at first and usually only a dentist can see it, but as time goes on an implant that hasn't integrated properly can shift when you chew or speak. Implants that have failed completely with frequently.

Other warnings signs of impending failure include pain, inflammation, and infection, but these do not always occur. If Dr. Eshraghi notices that your implant is moving, he may conduct an x-ray to make sure the bone is growing. If the implant is failing, the x-ray may reveal considerable bone loss around the metal area.

Repair and Replacement


In cases where the implant crown becomes cracked or detached, it is an easy matter for us to attach a new, or make any other repairs if necessary. However, if the damage to the implant is too severe, we will need to remove and replace it.

It is easy for us to remove a failed dental implant, but we will need to use a local anesthetic for this procedure. Once the implant is removed Dr. Eshraghi will carefully clean the area. Then we can begin the process of inserting a new implant, making careful note of what went wrong the first time. If there is enough healthy bone in the same area, we won't need a bone graft.

However, in cases of significant bone loss, we may need to place a bone graft to improve the site of the removed implant before placing a new one. Once the bone graft is complete, your mouth may need several months to heal before we can put in a new implant. During the healing period, Dr. Eshraghi may ask you to quit smoking, postpone cancer treatment or make other lifestyle adjustments that will reduce the risk of the next implant failing as well.

Always remember to take good care of your implants by brushing and flossing daily. Also take care to eat a balanced diet and abstain from using your teeth as tools, as this can chip them. If you experience any problems with your implants, contact us right away.

Dental Crowns


Rendering of jaw with dental crownDental crowns are caps that are placed over damaged teeth to repair them and bring them back to their regular function, size and shape. Crowns strengthen teeth and make them look normal again.

When Are Crowns Needed?


There are a variety of situations that call for a crown. For instance, you might need to cover a tooth that is improperly shaped or discolored. Fractured, weakened and worn teeth can also benefit from , , as do teeth that have cavities too large for fillings. They are also used following root canal treatment to protect the newly restored tooth.

What are Crowns Made of?


Many different materials (and combinations of materials) are used to form crowns, including composite resin, porcelain, porcelain fused to metal, metal alloys and ceramics. When we make crowns, we color the material to match the rest of your teeth and ensure that it fits comfortably and naturally in your mouth.

Dr. Eshraghi will consider multiple factors when deciding which kind of material to use for your crown, such as the tooth’s location in the mouth and the position of the adjacent gum tissue. Other factors include the tooth’s function, its shade and color, and the amount of it that is shown while smiling. We will also take your personal preferences into account as well.

Procedure for Placing a Crown


We usually require two separate dental appointments to place a crown over a tooth, and it involves a multistep process. First, Dr. Eshraghi will prepare the tooth by taking off the outer layer to make room for the crown. He will also remove any decay and, if necessary, build up the core of the tooth if he needs to augment the tooth’s structure.

The next step is to make an impression of the tooth, either from a mold or a digital scan. This impression will act as a precise model for the crown as we’re crafting it. Making a crown takes about two weeks or less, but we also have an expedited process that allows us to get the entire procedure done in one visit.

Then we’ll install a temporary crown that will protect the prepared tooth until the permanent crown is completed. The tooth covered by the temporary crown will have an increased sensitivity to hot and cold foods, so avoid those along with sticky foods and gum until you get the final crown.

Once the crown is finished, Dr. Eshraghi will place it on the prepared tooth and make any needed adjustments. Once both of us are satisfied with its appearance and feel, we will cement it into place.

Taking Care of Your Crowns


Once your crowns are successfully installed, you can treat them just like natural teeth. However, crowns can still break, and the underlying tooth is still subject to cavities, so make sure to brush and floss every day. Also take care to avoid chewing ice, hard foods and objects. Doing so can damage tooth-colored crowns.

If you experience any problems with your crowns contact us right away, and don’t forget to come in for biannual dental exams and cleanings.
