    • 12/26/12Read MoreTooth Trauma (Part III of IV)If a tooth has been displaced in a traumatic accident, as long as the x-ray doesn't show any root fractures, then the dentist can usually move the tooth back into its original position. Then, the tooth is usually splinted to the adjacent teeth during the healing period. This is done by attaching a wire to the front teeth with composite. Composite is the tooth colored filling material routinely used to fill cavities. When one of the teeth has been chipped, the primary focus tends to be on that tooth. However, in a traumatic injury to the mouth, it is not unusual to have multiple teeth having been injured. When a tooth fractures, then, the force of the blow is dissipated. Unfortunately, the intact teeth will transmit all of the energy of the insult directly onto the end of the root. The problem with this is that the end of the root is where the nerves and blood vessels enter the tooth. If the force is great enough, then the nerve and blood vessels can be severed. This will cause the nerve to die and will necessitate root canal treatment to save the tooth. It's hard for a dentist to tell right away whether a traumatically injured tooth may need root canal treatment. Many times, it takes up to six months before a dead nerve can be detected, and there are times that the damage will show up decades after the initial injury.Read More
    • 12/26/12Read MoreTooth Trauma (Part II of IV)If a front tooth has been chipped in a fall, and there is no telltale red dot in the center of the tooth indicating an exposure of the nerve, then immediate treatment is not necessary. It's likely that the tooth would be very sensitive to cold, so cool liquids are best to be avoided. The tooth could also be painful to chew on. It is usually best to wait until your dental visit to rule out root fractures before attempting to chew on a traumatically chipped tooth. The teeth could also ache so a pain reliever with anti-inflammatory properties would be most helpful. Ibuprofen tends to work the best. Over-the-counter preparations come in 200mg tablets, so an adult could take as many as four tablets, for a total of 800mg per dose to stay comfortable. Once at the dental office, the dentist will x-ray the teeth, check for root fractures, and check for loose or displaced teeth. If the root is fractured, the tooth may or may not need to be removed. It depends on where the fracture is. The closer to the end of the root, the better the chance that the tooth could be saved. If there are any teeth that are loose, they may need to be splinted in place. This would be just like placing a cast on a broken arm to allow for undisturbed healing.Read More
    • 12/26/12Read MoreIV Sedation in DentistryIt is not unusual to have some apprehension before a dental appointment. Most, if not all, of that normally goes away once the area to be treated has been numbed. However, some people have dental phobias, usually related to past, unpleasant experiences that make even a routine dental visit a stressful occasion. For most of these people, either nitrous oxide and/or oral sedation is adequate to quell the fears, but there are still a few who need deeper sedation. There are a number of wonderful medications that can be delivered intravenously. Since these are given IV, they can be titrated (adjusted) to the perfect level for each individual patient. We use Versed (midazolam) in our office. It is a very safe sedative that can fully relax a patient, but keep their protective reflexes and their ability to respond to commands intact. We monitor vital signs continuously to assure the highest level of safety. It is important that the patient does not have anything to eat or drink after midnight. They also must have a ride home after the procedure and should not drive or operate machinery for the next 24 hours. The addition of IV sedation to a dentist's armamentarium can make a dental procedure extremely pleasant for even the most fearful patient.Read More
    • 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
