Nitrous Oxide for Children

Your child won't keep his or her first teeth forever, but that doesn't mean those tiny pearly whites don't need conscientious care. Maintaining your child's dental health now will provide health benefits well into adulthood, as primary (baby) teeth serve some extremely important functions.

For one thing, primary teeth serve as guides for the eruption of permanent (adult) teeth, holding the space into which these new teeth will erupt. The crowns (tops) of the permanent teeth actually push against the roots of the baby teeth, causing them to resorb, or melt away. In this way, the adult teeth can take their proper place.

What's more, your child's primary teeth will be there for most of childhood, helping your child to bite, chew and speak. For the first six or so years, he or she will be relying on primary teeth exclusively to perform these important functions. Until around age 12, your child will have a mix of primary and permanent teeth. You will want to make sure those teeth stay healthy and are lost naturally — when it's time.

Your Child's First Teeth

Kids mouth anatomy.

Your child's 20 baby teeth will begin to appear usually between six and nine months, though in some cases it may start as early as three months or as late as twelve months. The two lower front teeth tend to erupt first, followed by the two upper ones, these teeth are called the central incisors. Then the neighboring teeth called lateral incisors will erupt too. The first molars come in next, followed by the canines (eyeteeth). And finally, the last teeth to erupt are the two-year molars. Sometimes your baby can experience teething discomfort during this process. If so, there are courses of action to help make your child more comfortable.

Your infant's gums should be gently wiped after each feeding with a water-soaked gauze pad or damp washcloth. As soon as the first tooth erupts, establish a daily brushing routine with a small, soft-bristled toothbrush and no more than a thin smear of fluoridated toothpaste. Your child may need your help with this important task until about the age of 6.

Your Child's First Dental Appointment

Age one dental visit

The American Academy of Pediatric Dentistry recommends that your child see a dentist by his/her first birthday, or as early as the first tooth erupts. Though this may sound early, learning proper pediatric oral hygiene techniques, checking for cavities, and watching for developmental problems is extremely important.

There are a number of forms of tooth decay that can affect babies and small children. Early Childhood Caries (tooth decay) can develop rapidly, progressing from the hard, outer enamel layer of a tooth into the softer, inner dentin in six months or less.

Most of all, it's important for your child to have a positive experience at the dental office as he/she will be a regular visitor for years to come.

Pediatric Dental Treatments

There are a variety of dental treatments offered to prevent tooth decay in children, or to save or repair teeth when necessary. They include:

Topical Fluoride — Fluoride incorporates into the enamel of teeth, making it harder and more resistant to decay. Although there is a small amount of fluoride in toothpastes and in some drinking water supplies, a higher concentration can be applied professionally to your child's teeth for maximum protection.

Dental Sealants — A plastic coating can be applied at the dental office to prevent cavities by sealing the little grooves on the chewing surfaces of back teeth known as “pits and fissures.” These little crevices become the perfect environments for decay-causing bacteria. Immature tooth enamel is more permeable and therefore less resistant to tooth decay. Dental sealants are easy to apply and provide years of protection (Watch Dental Sealant Video).

Root Canal Treatment — Perhaps you have had a root canal treatment yourself, to save an injured or severely decayed tooth. Well, sometimes children need root canals, too. In children these are called pulpotomies or pulpectomies. As mentioned above, baby teeth are important guides to the permanent teeth that are already forming beneath your child's gums. Therefore, saving them from premature loss can help prevent a malocclusion (“mal” – bad; “occlusion” – bite) that requires orthodontic treatment.

Bonding — Chips and minor fractures to front teeth — common childhood occurrences — can be repaired with tooth-colored bonding materials. These lifelike resins made of plastic and glass can be used on baby teeth as well as permanent teeth and last until the youngster has completed facial growth (Watch Bonding Video).

Orthodontic Concerns

Orthodontic Problems.

By around age 7, most malocclusions have become evident. Interceptive orthodontic treatment around this time can help direct proper tooth positioning and/or jaw growth, eliminating or simplifying the need for later treatment. There are many orthodontic problems that can be detected early and are examples of why a trained professional should evaluate your child during his/her growth and development.

Sports & Your Child's Teeth

If your child is active in sports, a custom-made mouthguard is a highly recommended safeguard. According to the American Dental Association, an athlete is 60 times more likely to suffer dental harm when not wearing one of these protective devices. A custom mouthguard is made specifically for your child using a model of his or her teeth. This will offer greater protection than an off-the-shelf model. It's an investment that pays off highly in the form of reduced pain, suffering — and dental expenses down the road!

Child in dental chair.Some children are just too fearful to receive necessary dental care. In that type of situation, conscious sedation with nitrous oxide may be recommended to help make your child's experience of dental treatment stress-free.

Nitrous oxide, a colorless gas with a slightly sweet odor, has been used in medicine for about a century. It's a safe and effective method of administering conscious sedation, which means that a child (or adult) will stay awake during the procedure, but feel completely relaxed — even happy. All bodily functions remain normal during the administration of nitrous oxide, and its effects wear off quickly afterwards.

How Is Nitrous Oxide Administered?

Nitrous Oxide for children.As a form of conscious sedation, nitrous oxide is inhaled through a small mask that fits comfortably over a child's nose. The gas is mixed with oxygen as it is being delivered, and both gases are always kept at a level that is safe for the body. In just a few minutes, the patient may start to experience a floating sensation, and perhaps some tingling in the hands and feet. That's a sign that the sedation is working. Once it has been verified that your child is calm and comfortable, and that the dose is correct, the dental procedure can begin.

Nitrous oxide itself isn't a substitute for a local anesthetic in children or adults as it's considered an anxiolytic, which means it makes anxiety disappear. However, for some pediatric procedures, a child receiving nitrous oxide may not need an anesthetic injection. Even if they do need a numbing shot, they won't mind at all while under sedation with nitrous oxide. Yet they won't be asleep — they'll be able to speak, be aware of what's going on, and they will remain in control during the procedure. In fact, the dose can be fine-tuned to just the level of sedation they need to make them comfortable yet alert.

When the procedure is over, the flow of nitrous oxide is decreased to zero, and the oxygen will be increased. After resting in the chair for a few minutes, the child will feel completely normal.

Who Can Benefit From Nitrous Oxide?

Any child whose anxiety would preclude dental treatment can benefit from conscious sedation with nitrous oxide. Before your child is treated, you will be asked for a complete medical history, including any medications your child is taking. Your child will be kept safe and comfortable throughout the procedure, and will likely not remember a thing about it afterwards.
