Seal Out Tooth Decay in Your Children's Teeth

Sealants are a plastic barrier to protect the chewing surfaces of the eight permanent molars from decay. The six-year molars usually erupt (come in) between five and seven years of age and the twelve-year molars erupt around 11 to 14 years of age. More than 90% of decay occurs in the deep grooves of the chewing surfaces of these molars. When teeth first erupt, the enamel is not completely calcified (hardened), and the teeth are very susceptible to decay. Dental sealants should be applied as soon as the molars are in far enough to see the entire chewing surface. If a primary (baby) molar has early decay on a chewing surface, and the child is cooperative, a sealant may be recommended. Once decay has penetrated the second layer of tooth structure, a restoration (filling) must be placed.

The application of a sealant is painless, but does require cooperation. A very high flow of saliva, a strong gag reflex, or an inability to open the mouth wide enough for access to the molars, will make the procedure difficult. Your pediatric dentist will use various methods to manage these circumstances. The most important requirement for a quality sealant is your child's cooperation.

In order to see how the sealant is performed, you and your child could ask if you may watch the procedure being performed on another child or your dentist may have a videotape or DVD that you may view. There are four six-year molars and four twelve-year molars. Because the teeth do not always come in at the same time, all four permanent molars may not be sealed during one visit.

First, the tooth must be isolated from saliva. Remember, the tooth must be dry for the sealant to bond tightly to the tooth surface. A gel will be applied for 15 seconds. After this is rinsed away with water, the sealant is applied (usually with a tiny brush). A bright light is used to harden the sealant. There is no heat or sensation from the light. The procedure takes only minutes for each tooth. Your child may eat right away.

Sealants do wear out. Retention rates are about 85% over three years. Grinding teeth and chewing ice, popcorn kernels, or hard candy can crack sealants. How well the child's enamel bonds with the sealant will often determine how long a sealant will last. If a sealant is lost, the tooth is still more protected from decay than if the tooth had never been sealed. Decay will probably not occur if the sealant is replaced during the next six-month dental check-up. If your child has had a problem with cavities and his or her oral hygiene is very poor, decay can still occur.

Sealants are one of the very best things dentistry has to offer. Seal out your child's decay!

Child's Dentist: Tongue Piercing Damages the Mouth

Tongue piercing carries some very serious risks. It can cause a wide range of problems, some even permanent. The pain from the piercing itself might be much more than temporary. It can actually get worse because of excessive swelling and infection and require medical treatment.

The mouth is a hard place to sterilize, so infections are common. Piercing establishments don't always maintain a sterile environment either. They are not regulated by law and many operators are not even licensed. The piercing operator might not be experienced or be thinking of your health and safety. He or she may not even know that the tongue has major blood vessels within it. If pierced in the wrong place -- bingo! You bleed badly. Excessive swelling of your tongue can even block your breathing passages.

The tongue is a breeding ground for bacteria. Piercing the tongue causes an open wound. Bathing it in antiseptic mouthwash isn't enough to kill bacteria. Without the ability to keep bacteria out, infection can develop, and lead to throbbing pain and a trip to the doctor or dentist.

Even if you get through the piercing without too much pain, swelling, or bleeding, you still run the risk of other complications. The jewelry might chip your teeth. It can damage your teeth from the inside, too, and that trauma may require an expensive root canal or crown. Over time, the jewelry can irritate your gums. Or, your fancy jewelry can go right "down the tubes" -- you might swallow or even choke on it, or have it lodge in your lungs.

Tongue Piercing Can Cause:

• Pain
• Swollen tongue
• Infection
• Severe bleeding
• Blood poisoning
• Increased saliva flow
• Gum injury
• Internal resorption (the tooth dissolves from the inside out)
• Chipping of teeth
• Tooth damage requiring crowns, root canals, or other restoration
• Delayed healing
• Allergic reactions to metals
• Choking
• Difficulty eating
• Difficulty speaking
• Life threatening diseases (for example, AIDS and hepatitis) caused from infected needles

Mouth jewelry attracts attention, sometimes the type you aren't looking for -- like dental and medical attention. Be cool. Think smart. Don't put your jewelry where your mouth is.
