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.

Nitrous Oxide

The usual plan is for Dr. Eshraghi to remove plaque from your teeth through brushing and scraping, polish them to eliminate any stains, check under the tongue, perform a professional flossing, then give you a few suggestions on how to keep your teeth clean and schedule the next appointment.

However, in cases where we need to perform more invasive dental work such as surgery, we may need to use nitrous oxide (N2O), also known as laughing gas. Like many aspects of dentistry, laughing gas is not well understood in the general public. What is laughing gas and what does it do?

What is Nitrous Oxide?


Nitrous oxide is a colorless, odorless form of sedation that releases pleasurable feelings to relax patients. It works quickly and has irreversible effects, lending much to its effectiveness. We administer it using a breathing mask before invasive dental procedures.

Does Nitrous Oxide Produce any Side Effects?


According to the CDA, the overwhelming majority of patients who receive nitrous oxide treatment don't experience any side effects. When side effects do occur, however, they are usually because the nitrous level is too high or the amount the patient is inhaling changes rapidly. Possible side effects include shivering, fatigue, nausea, excessive sweating, headaches, and vomiting.

Recovery Period


When we turn off the laughing gas, we give the patient oxygen for about five minutes. The oxygen will prevent headaches, help the patient regain their alertness, and purge any gas that might remain in the lungs.

We also recommend that you eat a light meal before receiving laughing gas and avoid large meals for three hours after the procedure. Dr. Eshraghi will also let you know when you can drive safely again.

Is Nitrous Oxide Safe for Children


Laughing gas is not only safe for children, but it's a preferred option for children with dental anxiety. Some children, however, may get nauseous if they receive this treatment. Others can have trouble wearing the mask properly, so it's not for everyone. If your child needs a more invasive treatment, Dr. Eshraghi will work with you to determine whether nitrous oxide is necessary.

Caveats


Despite its ease of administration, laughing gas isn't the best option in every single case. It is not recommended for patients with certain conditions, such as those who:

[[[Are in the first three months of pregnancy
~Have a record of drug addiction or emotional issues
~Receive bleomycin sulfate treatment
~Have COPD (chronic obstructive pulmonary disease)
~Have a cobalamin deficiency
~Have a methylenetetrahydrofolate reductase deficiency]]]


But the best option is to practice good dental hygiene and thus prevent any need for invasive dental procedures involving nitrous oxide. Brush your teeth twice a day and floss once a day to prevent bacteria, plaque, and tartar from building up. Come in for dental exams and professional cleanings twice a year so we can provide a higher level of cleaning that you can do yourself and access the hard-to-reach areas.
