Tooth Decay Prevention
Tooth decay is a progressive disease resulting in the interaction of bacteria that naturally occur on the teeth and sugars in the everyday diet. Sugar causes a reaction in the bacteria, causing it to produce acids that break down the mineral in teeth, forming a cavity. Dentists remove the decay and fill the tooth using a variety of fillings, restoring the tooth to a healthy state. Nerve damage can result from severe decay and may require a crown (a crown is like a large filling that can cap a tooth, making it stronger or covering it). Avoiding unnecessary decay simply requires strict adherence to a dental hygiene regimen: brushing and flossing twice a day, regular dental checkups, diet control and fluoride treatment. Practicing good hygiene avoids unhealthy teeth and costly treatment.
The grooves and depressions that form the chewing surfaces of the back teeth are extremely difficult (if not impossible) to clean of bacteria and food. As the bacteria reacts with the food, acids form and break down the tooth enamel, causing cavities. Recent studies indicate that 88 percent of total cavities in American school children are caused this way.
Tooth sealants protect these susceptible areas by sealing the grooves and depressions, preventing bacteria and food particles from residing in these areas. Sealant material is a resin typically applied to the back teeth, molars and premolars and areas prone to cavities. It lasts for several years but needs to be checked during regular appointments.
Fluoride is a substance that helps teeth become stronger and resistant to decay. Regularly drinking water treated with fluoride and brushing and flossing regularly ensures significantly lower cavities. Dentists can evaluate the level of fluoride in a primary drinking water source and recommend fluoride supplements (usually in tablets or drops), if necessary.
Sucking is a natural reflex that relaxes and comforts babies and toddlers. Children usually cease thumb sucking when the permanent front teeth are ready to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. If you notice prolonged and/or vigorous thumb sucking behavior in your child, talk to your dentist.
Here are some ways to help your child outgrow thumb sucking:
- Don't scold a child when they exhibit thumb sucking behavior; instead, praise them when they don't thumb suck.
- Focus on eliminating the cause of anxiety—thumb sucking is a comfort device that helps children cope with stress or discomfort.
- Praise them when they refrain from the habit during difficult periods.
- Place a bandage on the thumb or a sock on their hand at night.
Normally the first tooth erupts between ages 6 to 12 months. Gums are sore, tender and sometimes irritable until the age of 3. Rubbing sore gums gently with a clean finger, the back of a cold spoon or a cold, wet cloth helps soothe the gums. Teething rings work well, but avoid teething biscuits—they contain sugar that is not good for baby teeth.
While your baby is teething, it is important to monitor the teeth for signs of baby bottle decay. Examine the teeth, especially on the inside or the tongue side, every two weeks for dull spots (whiter than the tooth surface) or lines. A bottle containing anything other than water and left in an infant's mouth while sleeping can cause decay. This happens because sugar in the liquid mixes with bacteria in dental plaque, forming acids that attack the tooth enamel. Each time a child drinks liquids containing sugar, acids attack the teeth for about 20 minutes. When awake, saliva carries away the liquid. During sleep, the saliva flow significantly decreases and liquids pool around the child's teeth for long periods, covering the teeth in acids.
Infant's New Teeth
The primary, or "baby," teeth play a crucial role in dental development. Without them, a child cannot chew food properly and has difficulty speaking clearly. Primary teeth are vital to development of the jaws and for guiding the permanent (secondary) teeth into place when they replace the primary teeth around age 6.
Since primary teeth guide the permanent teeth into place, infants with missing primary teeth or infants who prematurely lose primary teeth may require a space maintainer, a device used to hold the natural space open. Without a maintainer, the teeth can tilt toward the empty space and cause permanent teeth to come in crooked. Missing teeth should always be mentioned to your family dentist. The way your child cares for his/her primary teeth plays a critical role in how he/she treats the permanent teeth. Children and adults are equally susceptible to plaque and gum problems—hence, the need for regular care and dental checkups.
A Child's First Dental Visit
A child's first dental visit should be scheduled around his/her first birthday. The most important part of the visit is getting to know and becoming comfortable with a doctor and his staff. A pleasant, comfortable first visit builds trust and helps put the child at ease during future dental visits. If possible, allow the child to sit in a parent's lap in the exam room. Children should be encouraged to discuss any fears or anxiety they feel.
Why Primary Teeth Are Important
Primary teeth are important for several reasons. Foremost, good teeth allow a child to eat and maintain good nutrition. Healthy teeth allow for clear pronunciation and speech habits. The self-image that healthy teeth give a child is immeasurable. Primary teeth also guide eruption of the permanent teeth.
Good Diet and Healthy Teeth
The teeth, bones and soft tissue of the mouth require a healthy, well-balanced diet. A variety of foods from the five food groups helps minimize (and avoid) cavities and other dental problems. Most snacks that children eat cause cavities, so children should only receive healthy foods like vegetables, low-fat yogurt and cheeses, which promote strong teeth.
Infant Tooth Eruption
A child's teeth actually start forming before birth. As early as 4 months of age, the primary or "baby" teeth push through the gums—the lower central incisors are first, then the upper central incisors. The remainder of the 20 primary teeth typically erupt by age 3, but the place and order varies.
Permanent teeth begin eruption around age 6, starting with the first molars and lower central incisors. This process continues until around age 21. Adults have 28 secondary (permanent) teeth—32 including the third molars (wisdom teeth).
Preventing Baby Bottle Tooth Decay
Tooth decay in infants can be minimized or totally prevented by not allowing sleeping infants to breast or bottle-feed. Infants that need a bottle to comfortably fall asleep should be given a water-filled bottle or a pacifier. Our office is dedicated to fighting baby bottle tooth decay. Let us know if you notice any signs of decay or anything unusual in your child's mouth.
