Dental Care for Your Baby

1.When should my child first see a dentist?

"First visit by first birthday" sums it up. Your child should visit a dentist when the first tooth comes in, usually between 6 and 12 months of age. This visit will establish a dental home for your child. Early examination and preventive care will protect your child smile now and in the future.

2. Why so early? What dental problems could a baby have?

The most important reason is to begin a thorough prevention program. Dental problems can begin early. A big concern is Early Childhood Caries (formerly known as baby bottle tooth decay or nursing caries). Once a child diet includes anything besides breast-milk, erupted teeth are at risk for decay. The earlier the dental visit, the better the chance of preventing dental problems. Children with healthy teeth chew food easily and smile with confidence. Start your child now on a lifetime of good dental habits.

3. How can I prevent tooth decay from nursing or using a bottle?

At-will breast-feeding should be avoided after the first primary (baby) teeth begin to erupt and other sources of nutrition have been introduced. Children should not fall asleep with a bottle containing anything other than water. Drinking juice from a bottle should be avoided. Fruit juice should only be offered in a cup with meals or at snack time.

4. When should bottle-feeding be stopped?

Children should be weaned from the bottle at 12-14 months of age.

5. Should I worry about thumb and finger sucking?

Thumb sucking is perfectly normal for infants; many stop by age 2. Prolonged thumb sucking can create crooked teeth or bite problems. If the habit continues beyond age 3, a professional evaluation is recommended. Your dentist will be glad to suggest ways to address a prolonged thumb sucking habit.

6. When should I start cleaning my baby teeth?

The sooner the better! Starting at birth, clean your child gums with a soft infant toothbrush or cloth and water. As soon as the teeth begin to appear, start brushing twice daily using fluoridated toothpaste and a soft, age-appropriate sized toothbrush. Use a "smear" of toothpaste to brush the teeth of a child less than 2 years of age. For the 2-5 year old, dispense a "pea-size" amount of toothpaste and perform or assist your child toothbrushing. Remember that young children do not have the ability to brush their teeth effectively.

7. Any advice on teething?

From six months to age 3, your child may have tender gums when teeth erupt. Many children like a clean teething ring, cool spoon or cold wet washcloth. Some parents swear by a chilled ring; others simply rub the baby gums with a clean finger.

7 Ways to Protect your child's Oral Health

1.Start Oral Care Early

Your child should see a dentist by the time he's a year old, according to the American Academy of Pediatrics and the American Academy of Pediatric Dentistry.

2.Teach the Brush & Floss Habit
Tooth brushing is also crucial from the start. Even before your baby has teeth, you can gently brush the gums, using water on a soft baby toothbrush, or clean them with a soft washcloth.Once there are additional teeth, parents have to buy infant toothbrushes that are very soft. Brushing should be done twice daily using a fluoridated toothpaste.
Flossing should begin when two teeth touch each other. Parents have to clean the teeth until children are able to tie their shoes or write in cursive.

3.Avoid "Baby Bottle Decay"
For years, pediatricians and dentists have been cautioning parents not to put an infant or older child down for a nap with a bottle of juice, formula, or milk.The sugary liquids in the bottle cling to baby's teeth, providing food for bacteria that live in the mouth. The bacteria produce acids that can trigger tooth decay. Left unchecked, dental disease can adversely affect a child's growth and learning, and can even affect speech.
If you must give your child a bottle to take to bed, make sure it contains only water, according to the American Academy of Pediatrics guidelines.

4.Control the Sippy Cup Habit
Bottles taken to bed aren't the only beverage problem. Juice given during the day as a substitute for water and milk is another. Often, that juice is in a sippy cup. It's meant as a transition cup when a child is being weaned from a bottle and learning to use a regular cup.
Parents mistakenly think juice is a healthy day-long choice for a beverage. But that's not the case. Prolonged use of a sippy cup can cause decay on the back of the front teeth, if the beverages are sugary. The American Academy of Pediatrics advises parents to limit the intake of 100% fruit juice to no more than four ounces a day. Sugary drinks and foods should be limited to mealtimes.

5.Ditch the Binky by 2 or 3
Sucking too strongly on a pacifier, for instance, can affect how the top and bottom teeth line up (the "bite") or can affect the shape of the mouth. Pacifiers should be dropped by age 2.

6.Beware of Mouth-Unfriendly Medicines
Many medications that children take are flavored and sugary. If that sticks on the teeth, the risk for tooth decay goes up.
Children on medications for chronic conditions such as asthma and heart problems often have a higher decay rate.
Antibiotics and some asthma medications can cause an overgrowth of candida (yeast), which can lead to a fungal infection called oral thrush. Suspect thrush if you see creamy, curd-like patches on the tongue or inside the mouth.

7.Stand Firm on Oral Hygiene
• Plan to help your children longer than you may think necessary. "Children don't have the fine motor skills to brush their own teeth until about age 6," says Hayes. Flossing skills don't get good until later, probably age 10.
• Schedule the brushing and flossing and rinsing, if advised, at times when your child is not overly tired. You may get more cooperation from a child who isn't fatigued.
• Get your child involved in a way that's age-appropriate. For instance, you might let a child who is age 5 or older pick his own toothpaste at the store, from options you approve. You could buy two or three different kinds of toothpaste and let the child choose which one to use each time. You may offer him a choice of toothbrushes, including kid-friendly ones that are brightly colored or decorated.
• Figure out what motivates your child. A younger child may gladly brush for a sticker, for instance, or gold stars on a chart.

Wisdom teeth: what is the optimal age for removal, and should all wisdom teeth be removed?

1.What is the optimal age for surgery?

The NIH study found that the lowest morbidity was associated with third molar removal in patients aged 15 to 25 or when the roots are two-thirds formed. Reasons for this included: more favorable root form, greater distance to the inferior alveolar nerve, softer/more pliable bone, and more rapid healing.

2.Should all third molars be removed?

The easy answer is "no."
 There are, however, many indications for third molar extraction, possibly too many to list in this short piece.

• Symptomatic teeth, including third molars with acute or chronic issues, including dental caries, pericoronitis, odontogenic abscess, etc.
• Any impacted tooth with associated pathology is indicated for extraction, and would include cyst and tumors. If pathology is suspected, a biopsy of the associated tissue should be planned.
• Periodontal compromise of adjacent teeth.
• If orthognathic surgery is planned-specifically a bilateral sagittal-split osteotomy-removal of the third molars should be planned for a more predictable surgical outcome.
• Second molars that have failed to erupt often have the developing third molars just distal to them. Once this is recognized, the second molars are effectively "pinned" into place. Extraction of the third molars often allows these teeth to erupt.
• Arch length deficiency.
• There are many special cases when third molar extractions are indicated, including fractures, complex medical issues, or behavioral issues.

No-Prep Veneers

No-prep porcelain veneers ( such as Lumineer ) have been around for more than two decades, and the incredible success of bonding porcelain to 100% enamel is well-documented.

Now, there are refined techniques, new and improved materials, and better training in emulating nature so that the end result of prepless veneers can rival or exceed the results of traditionally prepared veneers. Contrary to common thinking, this style of dentistry is not easy; in fact, if done well, this approach can require more skill and expertise than traditional porcelain veneers.

Case selection for “prepless” veneers is critical, and, clearly, additive-only restorations are not for every situation. The case types that may be well-suited for no-preparation veneers are:

• microdontia such as peg laterals, tooth-to-arch discrepancies, and, in general, undersized teeth.
• short, worn teeth that have lost volume due to occlusal wear, abrasion, erosion, or some combination of these factors.
• bicuspid extraction orthodontic cases where anterior teeth are overly lingualized and the arch form is narrow.
• large lips that create a big frame and allow enlargement of the teeth for proper proportion.

In recent years, a new trend has emerged that will not likely be reversed: the movement toward more conservative preparations and even no preparation for many cosmetic smile design cases. It is strongly likely that this trend is here to stay as the consumer, when given a choice, will always seek out more conservative alternatives.

Root Canal Treatment in Seoul Korea

Root Canal Treatment

Good root canal treatments begin with proper diagnosis.

This involves listening to the patient’s description of the problem, followed by clinical tests to reproduce the patient’s subjective pain or symptoms.

The clinical tests that need to be incorporated into the diagnostic evaluation are 1) cold, electric pulp tester (EPT) and/or heat tests for pulp vitality; 2) percussion testing to determine the status of the periodontal ligament; 3) palpation testing to evaluate the gingival tissue and bone for infection or inflammation; 4) probing and mobility testing; and lastly, 5) radiographic examinations.

Also, it is important to review a patient’s medical and dental history as part of the diagnostic process.

One of the more influential factors regarding the long-term restorative prognosis is the periodontal (surrounding gum and bone) status of the tooth being treated. Primary pathosis from a root canal certainly can cause secondary periodontal lesions. When the root canal etiology is removed in these situations, the periodontal problem is also likely to resolve. However, when the bone loss is primarily from gum disease, it can create a less predictable prognosis for the tooth even with the appropriate root canal treatment.

Root canal disease is mediated by bacteria.

Treatment goals should be directed to reducing the critical concentration of microbial irritants to the lowest level possible. Thorough canal instrumentation, with either stainless steel hand files or Ni-Ti rotary files, removes the bulk of tissue and microbial contamination, but adjunctive chemical agents are needed to optimize debridement. Current concepts support the following approaches:

• lubricating and chelating agents during cleaning and shaping,
• copious irrigation during all phases of instrumentation with 2.5% sodium hypochlorite, constantly refreshed
• deep penetration of a side port, narrow gauge irrigating needle, constantly moving in and out of the canal space during each irrigation
• removal of residual smear layer at completion of instrumentation prior to obturation.

In addition to the quality of the root canal treatments performed ,root canal success is equally dependent upon the quality of the coronal seal established by a filling and a crown,during and after the procedure. Consideration also must be given to whether the tooth will need a post.
Timely placement of these restorations are critical. If bacteria are allowed to enter the coronal portion of the root canal, they will eventually penetrate the interface between root canal and the obturation material, resulting in recontamination of the canal space and subsequent inflammation.

Root canal performed teeth tend to get drier, more brittle over time,and more prone to frature. Tooth fractures occur while chewing foods most of the time. Crowning prevents these possible tooth fractures by embracing the tooth as one entity. It is hard to predict when the root canal tooth will break. The best timing for crowning  might be the night before the tooth will break. :-)
Before treatment planning a crown for a root canal treated tooth, the tooth should show;
1. Radiographic evidence of a good apical seal.
2. No sensitivity to pressure (percussion).
3. No sensitivity to palpation of the periapical area.
4. The tooth is asymptomatic.
5. Acceptable root canal filling.
