    • 03/01/15Read MoreFilling Children's Teeth (Part III)When filling children’s teeth, I ALWAYS use local anesthetic on children. My practice includes a large segment of adult patients requiring sedation. The overwhelming reason for their extreme fear of the dentist is because their dentist didn’t use novocaine when they had their teeth filled as a kid. By numbing teeth ahead of time, a tooth can be drilled on without any pain whatsoever. Fear of the “shot” is a very common issue in children (not to mention many adults). We try to make that part of the visit as easy as possible for the patient. We start with a topical numbing gel that is placed on the gum at the injection site with a cotton swab. Once the gum is fully numb, the child is told that they will feel a little “pinch”. The anesthetic syringe is passed to the dentist out of sight of the patient. By quickly inserting the needle into the numbed gums and very slowly injecting the anesthetic solution, the child experiences little to no discomfort. It is such a heart-warming feeling to hear a child run out to the waiting room saying “Mommy, Mommy - I didn’t have to have a shot! He just pinched my gums.”Read More
    • 03/01/15Read MoreFilling Children's Teeth (Part II)Getting a child comfortable and relaxed once seated in the dental chair is paramount in having a good experience with a filling appointment. We have TVs in the ceiling that can show cartoons or children’s programming which can get most kids at ease. For those who continue to have reservations, many times just taking the time to explain what is going to happen can be enough to allay their fears. If a child continues to be unruly, the next step is nitrous oxide (laughing gas). This “Happy Gas” can be the final calming factor for many children. Every once in a blue moon, we will come across a child who is so fearful that they cannot be safely controlled. We do not use papoose restraints in our office, so sedation is the only alternative in those cases. Sedation of children is best handled by pedodontists. They have special training in sedating children who have a very variable response to many of the medications that are used. About once in every five years, I refer a child to specialist care.Read More
    • 03/01/15Read MoreFilling Children's Teeth (Part I)With patience and a gentle demeanor of the dentist, most children can have cavities filled with minimal fear and discomfort. As a patient in preparation for the visit, don’t use phrases like “Oh, it won’t hurt”, or “It will only hurt a little bit”. Use positive statements, like “Remember how you got your teeth cleaned? Well, Dr. G is going to clean out all of the cavities bugs”. The question of “Am I going to get a shot?” frequently comes up. The best answer to that is “Dr. G has a special pincher that will put your tooth to sleep so that you won’t feel it when he cleans out the cavity bugs”. When the day comes, we allow the parents to bring the child back into the treatment room, but when the time comes to start the treatment, we ask the family to go relax in the waiting room. We have found that 99% of pediatric patients are much more comfortable and much less fearful without a parent to get attention from. I have had screaming children clutching mom’s or dad’s arms, holding on for dear life, only to turn into placid little angels within 15 seconds of the parent’s departure.Read More
    • 03/01/15Read MoreChild's Dental ExamRegular dental exams and cleanings are extremely important for children in order to maintain their dental health. In our office, a routine cleaning visit consists of a thorough oral and dental exam. This includes a screening for oral cancer, an assessment of the gums and oral mucosa, a check for any growth abnormalities, visually checking for cavities in the teeth, and an orthodontic evaluation. Bitewing x-rays are taken of the back teeth in order to detect cavities in their early stages. Many times, if a cavity gets large enough to be seen visually, it could be already deep enough to be in the nerve which would greatly increase the cost to repair. The teeth are gently polished to remove plaque and then the teeth are bathed with a high concentration of pleasant-tasting fluoride. We have many flavors to choose from to satisfy event the pickiest of tastebuds. We recommend the routine check-up and cleaning to be every 6 months. Cavities tend to grow much quicker in children than adults, so an ounce of prevention is so much better than the pound of cure.Read More
    • 03/01/15Read MoreFirst Trip to the DentistYour child’s first trip to the dentist is a very special time in their life. Just like the first haircut, it can be fraught with fright. In the days before, it is best prepare them with positive comments. Statements like - “It will be a lot of fun”, or “They will shine your teeth so you have a pretty smile” go a much longer way than -“Oh, it won’t hurt”. In our office, we go out of our way to make that first visit a special occasion. We don’t force anything on them, but we positively reinforce good behavior each time they try something new. We have TVs in the ceiling that can play cartoons. That goes a long way to soothing any uneasiness. Then, to cap off the visit, there is a trip to the treasure chest filled with toys. And hopefully, there will be a picture taken to display in the “No Cavities Club”. Having a good experience during the first trip to the dentist can be tantamount in having good behavior in future visits.Read More
    • 12/29/13Read MoreVital Teeth BleachingBleaching of vital teeth has been a great thing for cosmetic dentistry. Teeth can be lightened considerably with out having to do any invasive drilling or bonding of tooth-colored materials onto the teeth. The cost is significantly cheaper than all other cosmetic dental procedures. Discolorations in teeth can come from many sources. Intrinsic stains (ones that are actually incorporated into the tooth structure itself), include antibiotics (especially tetracycline), fluorosis, and enamel hyperplasia. Aging will also naturally yellow the teeth. Foods such as tea, coffee, red wine, and colas and tobacco products will also discolor teeth. Extrinsic stains, stains that reside on the surface of the teeth, are caused by bacterial plaque accumulations soaking up pigmented food and drink. Extrinsic stains can be removed by a professional cleaning or by using a “whitening” toothpaste that has extra abrasives in it. Since intrinsic stains reside within the tooth enamel, they must be removed by chemicals that have the ability to soak into the tooth structure itself.Read More
