    • 12/26/12Read MoreNitrous Oxide SedationNitrous oxide (laughing gas) is an extremely helpful adjunct for dental treatment of the fearful patient. It was first discovered by Joseph Priestley in 1772, however, it was not until 1844 when Horace Wells used it as a medical anesthetic. Today, nitrous oxide is used in conjunction with local anesthetic when performing dental treatment on apprehensive patients. Nitrous oxide on its own cannot reliably anesthetize a patient profoundly enough for a patient not to feel a thing. Therefore, it must be used with novocaine to numb the area. Nitrous oxide is administered with pure oxygen and is breathed through a nasal hood. The machine that delivers the gas is a fail-safe machine which will turn off if the oxygen level falls below 35%. Nitrous oxide is not meant to put one to sleep, but merely relax. When given before the anesthetic injection, it can make that part of the procedure much more comfortable. It will put a patient in a state of mild euphoria and will alter the perception of sights, sounds, and time. It also has a mild amnesic effect leaving much less memory of the procedure. Another extremely nice feature of nitrous oxide is that the patient can be flushed with pure oxygen after the procedure and be totally lucid and able to drive home. Nitrous oxide can make a dental appointment a very pleasant experience.Read More
    • 12/26/12Read MoreOral Sedation for DentistryFear of dental treatment is very common. Some times, good anesthetic technique, behavior modification, and nitrous oxide (laughing gas) may not be enough for someone who is very fearful. Oral sedation comes to the rescue. It is important to get a good night's sleep before a dental appointment, but with dental phobics, that can be difficult to do. At our office, we use Ativan (lorazepam), a relatively long acting sedative. We prescribe two pills. One of those pills is taken before bedtime which helps a patient get a good night's sleep. The other pill is taken an hour before the appointment. Since Ativan is very long acting, there will still be some blood level left from the initial dose, thus providing for an extremely relaxed state once the dental appointment begins. Conscious sedation is very safe because the patient still has their protective reflexes and is able to respond to commands readily. However, they are extremely relaxed to the point that the sights, sounds, and vibrations associated with dental treatment are minimized immensely. The concept of time is altered so that the appointment seems to fly by and there is also an amnesic effect so that the patient has very little memory of the procedure. Afterwards, the patient is delightfully drowsy and will go home and have a very restful nap.Read More
    • 12/26/12Read MoreTips to Overcome One's Fear of the DentistThere are many ways to overcome one's fear of the dentist. First of all, don't wait until the tooth hurts. It makes it more difficult for the dentist to get you numb. Plus the pain leading up to the appointment can be associated with the dental visit itself. The dental appointment itself is really nothing to be fearful of as long as good local anesthetic technique is used to numb the area. Try to get a good night's sleep and avoid caffeinated drinks that could raise the anxiety level. For the novocaine injection, try to relax your muscles, especially your hands. Try this the next time you are in rush hour traffic and notice that your hands are tightly clasped to the steering wheel, consciously relax your grip and notice how the rest of your body will follow suit. Another trick is to find something on the ceiling to fixate on. We have televisions in our ceiling. This way patients can either watch cable TV or a serene aquarium movie to help keep their mind on things other than the injection. By flooding one's brain with visual stimuli and concentrating on relaxing the hands, the anesthetic injection experience can be minimized greatly. Once the initial numbness has been achieved, further injections can be done relatively pain free. The remainder of the appointment should be a piece of cake and should be fear free.Read More
    • 12/26/12Read MoreFear of the DentistFear of the dentist is a very common problem. It is not unusual for one to be somewhat apprehensive before one's dental appointment, however, a higher level of anxiety can be a result of a real dental phobia. Dental phobia can cause a person to avoid dental treatment. Many dental phobias start with a bad experience at the dentist, especially as a child. In our office, we never do any potentially painful treatment without first numbing the area. Since we are a sedation practice, we see a high number of dental phobic patients. The common source of their dental fears came from an experience where their dentist kept drilling on their tooth even though the individual indicated that it hurt. Another common problem comes from the patient delaying treatment until they are in extreme pain. Not only is it extremely difficult to get someone numb in that situation, but also even if you can get the tooth numb, just the experience alone can be enough to cause the patient to avoid further dental treatment.Read More
    • 11/30/12Read MorePlacement of Dental Implants Once the gum tissue has been reflected away from the bone, the surgeon can drill on the bone all day without any discomfort, only vibration because there are no nerve endings in the bone. To place an implant, there must be adequate bone to hold the titanium cylinder. Now 3D x-rays are available to accurately measure the amount of bone and to avoid major structures such as nerves and sinuses. An incision is made in the gums, then the gums are pulled back to give the surgeon full visibility of bone. A hole is drilled into the bone and then the titanium implant is screwed right into the bone. The gums are sutured back into place and the implant is left under the gums undisturbed for a number of months. This allows the bone to grow directly around the implant, a process called osseointegration. Finally, once the implant site has fully healed, the implant can be uncovered and restored to a new tooth.    Read More
    • 11/30/12Read MoreTooth Knocked Out On The Ball FieldIn my dental career, I have had the opportunity to assist two people who have had a tooth knocked out at a sporting event. The second one was during a baseball game that I was coaching. My left fielder ran at fullspeed right into the outfield fence. He was down on the ground while the ball was in play, then while I was running out to check on him (it was a high school field, so I had to run quite a ways to get to him), he got up and came to me with something in his hand. It was his front tooth. It turns out that of the ten foot sections of the cyclone fence, he would decide to choose the few inches of pole to collide with. Needless to say, when it came to toothversuspole - the pole won. There were no facilities at this field (it was serviced by a Port-A-John), I had him roll the tooth around in his mouth to clean it. Then, after asking his parent's permission, I reinserted it back into the socket. He handled it very well for a 14 year old because I could tell he saw stars when I put it in. After the game, I took him over to my office, opened up the tooth and placed medicine inside and then splinted it to the surrounding teeth with braces. Later I did a root canal on the tooth and removed the braces then and rebuilt the chipped tooth. Now his smile looks as good as new.  Read More
