best-dentist-bangalore-694654_640What Is A Pediatric Dentist?

A Pediatric Dentist has an extra two years of specialized training and is dedicated to the oral health of children from infancy through the teenage years. The very young, pre-teens, and teenagers all need different approaches in dealing with their behavior, guiding their dental growth and development, and helping them avoid future dental problems. A Pediatric Dentist is best qualified to meet these needs.

Why Are The Primary Teeth So Important?

It is very important to maintain the health of the primary teeth. Neglected cavities can and frequently do lead to problems which affect developing permanent teeth. Primary teeth, or baby teeth are important for (1) proper chewing and eating, (2) providing space for the permanent teeth and guiding them into the correct position, and (3) permitting normal development of the jaw bones and muscles. Primary teeth also affect the development of speech and add to an attractive appearance. While the front 4 teeth last until 6-7 years of age, the back teeth (cuspids and molars) aren’t replaced until age 10-13.

Dental Radiographs (X-Rays)

Radiographs (X-Rays) are a vital and necessary part of your child’s dental diagnostic process. Without them, certain dental conditions can and will be missed.

Radiographs detect much more than cavities. For example, radiographs may be needed to survey erupting teeth, diagnose bone diseases, evaluate the results of an injury, or plan orthodontic treatment. Radiographs allow dentists to diagnose and treat health conditions that cannot be detected during a clinical examination. If dental problems are found and treated early, dental care is more comfortable for your child and more affordable for you.

The American Academy of Pediatric Dentistry recommends radiographs and examinations every six months for children with a high risk of tooth decay. On average, most pediatric dentists request radiographs approximately once a year. Approximately every 3 years it is a good idea to obtain a complete set of radiographs, either a panoramic and bitewings or periapicals and bitewings. Pediatric dentists are particularly careful to minimize the exposure of their patients to radiation. With contemporary safeguards, the amount of radiation received in a dental X-ray examination is extremely small. The risk is negligible. In fact, the dental radiographs represent a far smaller risk than an undetected and untreated dental problem. Lead body aprons and shields will protect your child. Today’s equipment filters out unnecessary x-rays and restricts the x-ray beam to the area of interest. High-speed film and proper shielding assure that your child receives a minimal amount of radiation exposure.

Fluoride

Fluoride is an element, which has been shown to be beneficial to teeth. However, too little or too much fluoride can be detrimental to the teeth. Little or no fluoride will not strengthen the teeth to help them resist cavities. Excessive fluoride ingestion by preschool-aged children can lead to dental fluorosis, which is a chalky white to even brown discoloration of the permanent teeth. Many children often get more fluoride than their parents realize. Being aware of a child’s potential sources of fluoride can help parents prevent the possibility of dental fluorosis.

Some of these sources are:

  1. Too much fluoridated toothpaste at an early age.
  2. The inappropriate use of fluoride supplements.
  3. Hidden sources of fluoride in the child’s diet.

Two and three year olds may not be able to expectorate (spit out) fluoride-containing toothpaste when brushing. As a result, these youngsters may ingest an excessive amount of fluoride during tooth brushing. Toothpaste ingestion during this critical period of permanent tooth development is the greatest risk factor in the development of fluorosis.

Excessive and inappropriate intake of fluoride supplements may also contribute to fluorosis. Fluoride drops and tablets, as well as fluoride fortified vitamins should not be given to infants younger than six months of age. After that time, fluoride supplements should only be given to children after all of the sources of ingested fluoride have been accounted for and upon the recommendation of your pediatrician or pediatric dentist.

Certain foods contain high levels of fluoride, especially powdered concentrate infant formula, soy-based infant formula, infant dry cereals, creamed spinach, and infant chicken products. Please read the label or contact the manufacturer. Some beverages also contain high levels of fluoride, especially decaffeinated teas, white grape juices, and juice drinks manufactured in fluoridated cities. Another source of fluoride can be found in soft drinks at fast food restaurants, when blending the syrup and carbonation with the city water supply.

Parents can take the following steps to decrease the risk of fluorosis in their children’s teeth:

  1. Use baby tooth cleanser on the toothbrush of the very young child.
  2. Place only a pea sized drop of children’s toothpaste on the brush when brushing.
  3. Account for all of the sources of ingested fluoride before requesting fluoride supplements from your child’s physician or pediatric dentist.
  4. Avoid giving any fluoride-containing supplements to infants until they are at least 6 months old.
  5. Obtain fluoride level test results for your drinking water before giving fluoride supplements to your child (check with local water utilities).

Baby Bottle Tooth Decay (Early Childhood Caries)

One serious form of decay among young children is baby bottle tooth decay. This condition is caused by frequent and long exposures of an infant’s teeth to liquids that contain sugar. Among these liquids are milk (including breast milk), formula, fruit juice and other sweetened drinks.

Putting a baby to bed for a nap or at night with a bottle other than water can cause serious and rapid tooth decay. Sweet liquid pools around the child’s teeth giving plaque bacteria an opportunity to produce acids that attack tooth enamel. If you must give the baby a bottle as a comforter at bedtime, it should contain only water. If your child won't fall asleep without the bottle and its usual beverage, gradually dilute the bottle's contents with water over a period of two to three weeks.

After each feeding, wipe the baby’s gums and teeth with a damp washcloth or gauze pad to remove plaque. The easiest way to do this is to sit down, place the child’s head in your lap or lay the child on a dressing table or the floor. Whatever position you use, be sure you can see into the child’s mouth easily.

Eruption Of Your Child’s Teeth

Children’s teeth begin forming before birth. As early as 4 months, the first primary (or baby) teeth to erupt through the gums are the lower central incisors, followed closely by the upper central incisors. Although all 20 primary teeth usually appear by age 3, the pace and order of their eruption varies. Permanent teeth begin appearing around age 6, starting with the first molars and lower central incisors. This process continues until approximately age 21. Adults have 28 permanent teeth, or up to 32 including the third molars (or wisdom teeth).

Dental Emergencies

Toothache: Clean the area of the affected tooth thoroughly. Rinse the mouth vigorously with warm water or use dental floss to dislodge impacted food or debris. If the pain still exists, contact your child's dentist. DO NOT place aspirin on the gum or on the aching tooth. If the face is swollen apply cold compresses and contact your dentist immediately.

Cut or Bitten Tongue, Lip or Cheek: Apply ice to bruised areas. If there is bleeding apply firm but gentle pressure with a gauze or cloth. If bleeding does not stop after 15 minutes or it cannot be controlled by simple pressure, take the child to the hospital emergency room.

Knocked Out Permanent Tooth: Find the tooth. Handle the tooth by the crown, not the root portion. You may rinse the tooth but DO NOT clean or handle the tooth unnecessarily. Inspect the tooth for fractures. If it is sound, try to reinsert it in the socket. Have the patient hold the tooth in place by biting on a gauze. If you cannot reinsert the tooth, transport the tooth in a cup containing the patient’s saliva or milk. If the patient is old enough, the tooth may also be carried in the patient’s mouth. The patient must see a dentist IMMEDIATELY! Time is a critical factor in saving the tooth.

What is Pulpal Therapy?

The pulp of a tooth is the inner central core of the tooth. The pulp contains nerves, blood vessels, connective tissue and reparative cells. The purpose of pulp therapy in Pediatric Dentistry is to maintain the vitality of the affected tooth (so the tooth is not lost).

Dental caries (cavities) and traumatic injury are the main reasons for a tooth to require pulp therapy. Pulp therapy is often referred to as a "nerve treatment", "children's root canal", "pulpectomy" or "pulpotomy". The two common forms of pulp therapy in children's teeth are the pulpotomy and pulpectomy.

A pulpotomy removes the diseased pulp tissue within the crown portion of the tooth. Next, an agent is placed to prevent bacterial growth and to calm the remaining nerve tissue. This is followed by a final restoration (usually a stainless steel crown).

A pulpectomy is required when the entire pulp is involved (into the root canal(s) of the tooth). During this treatment, the diseased pulp tissue is completely removed from both the crown and root. The canals are cleansed, disinfected and in the case of primary teeth, filled with a resorbable material. Then a final restoration is placed. A permanent tooth would be filled with a non-resorbing material.

Does Your Child Grind His Teeth At Night? (Bruxism)

Parents are often concerned about the nocturnal grinding of teeth (bruxism). Often, the first indication is the noise created by the child grinding on their teeth during sleep. Or, the parent may notice wear (teeth getting shorter) to the dentition. One theory as to the cause involves a psychological component. Stress due to a new environment, divorce, or changes at school can influence a child to grind their teeth. Another theory relates to pressure in the inner ear at night. If there are pressure changes (like in an airplane during take-off and landing when people are chewing gum to equalize pressure) the child will grind by moving his jaw to relieve this pressure. The majority of cases of pediatric bruxism do not require any treatment. If excessive wear of the teeth (attrition) is present, then a mouth guard (night guard) may be indicated. The negatives to a mouth guard are the possibility of choking if the appliance becomes dislodged during sleep and it may interfere with growth of the jaws. The positive is obvious by preventing wear to the primary dentition. The good news is most children outgrow bruxism. The grinding gets less between the ages 6-9 and children tend to stop grinding between ages 9-12. If you suspect bruxism, discuss this with your pediatric dentist.

Mouth Guards

When a child begins to participate in recreational activities and organized sports, injuries can occur. A properly fitted mouth guard, or mouth protector, is an important piece of athletic gear that can help protect your child’s smile, and should be used during any activity that could result in a blow to the face or mouth. Mouth guards help prevent broken teeth, and injuries to the lips, tongue, face or jaw. A properly fitted mouth guard will stay in place while your child is wearing it, making it easy for them to talk and breathe. Ask your pediatric dentist about custom mouth protectors.

Thumb Sucking

Sucking is a natural reflex and infants and young children may use thumbs, fingers, pacifiers and other objects on which to suck. It may make them feel secure and happy or provide a sense of security at difficult periods. Since thumb sucking is relaxing, it may induce sleep.

Thumb sucking that persists beyond the eruption of the permanent teeth can cause problems with the proper growth of the mouth and tooth alignment. How intensely a child sucks on fingers or thumbs will determine whether or not dental problems may result. Children who rest their thumbs passively in their mouths are less likely to have difficulty than those who vigorously suck their thumbs.

Children should cease thumb sucking by the time their permanent front teeth are ready to erupt. Usually, children stop between the ages of two and four. Peer pressure causes many school-aged children to stop.

Pacifiers are no substitute for thumb sucking. They can affect the teeth essentially the same way as sucking fingers and thumbs. However, use of the pacifier can be controlled and modified more easily than the thumb or finger habit. If you have concerns about thumb sucking or use of a pacifier, consult your pediatric dentist.

A few suggestions to help your child get through thumb sucking:

  1. Instead of scolding children for thumb sucking, praise them when they are not.
  2. Children often suck their thumbs when feeling insecure. Focus on correcting the cause of anxiety, instead of the thumb sucking.
  3. Children who are sucking for comfort will feel less of a need when their parents provide comfort.
  4. Reward children when they refrain from sucking during difficult periods, such as when being separated from their parents.
  5. Your pediatric dentist can encourage children to stop sucking and explain what could happen if they continue.
  6. If these approaches don’t work, remind the children of their habit by bandaging the thumb or putting a sock on the hand at night. Your pediatric dentist may recommend the use of a mouth appliance.
