Throughout your life, you will have two sets of teeth: primary (baby) teeth and secondary (permanent) teeth. At age 6-8 months, the primary teeth appear; all 20 are in place by age 3.
Permanent teeth will begin to grow around age 6, and except for wisdom teeth, are all present between ages 12 and 14. The next teeth to grow in are the 12-year molars and finally the wisdom teeth. Wisdom teeth typically begin breaking through from age 17 and on. The total number of permanent teeth is 32, though few people have room for all 32 teeth. This is why wisdom teeth are usually removed.
Your front teeth are called incisors. The sharp “fang-like” teeth are canines. The next side teeth are referred to as pre-molars or bicuspids, and the back teeth are molars. Your permanent teeth are the ones you keep for life, so it is vital that they are brushed and flossed regularly and that periodic check-ups by a dentist are followed.
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 minerals 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 harder 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.
Caries, or tooth decay, is a preventable disease. While caries might not endanger your life, they may negatively impact your quality of life.
When your teeth and gums are consistently exposed to large amounts of starches and sugars, acids may form that begin to eat away at tooth enamel. Carbohydrate-rich foods such as candy, cookies, soft drinks and even fruit juices leave deposits on your teeth. Those deposits bond with the bacteria that normally survive in your mouth and form plaque. The combination of deposits and plaque forms acids that can damage the mineral structure of teeth, with tooth decay resulting.
Your teeth expand and contract in reaction to changes in temperature. Hot and cold food and beverages can cause pain or irritation to people with sensitive teeth. Over time, tooth enamel can be worn down, gums may recede or teeth may develop microscopic cracks, exposing the interior of the tooth and irritating nerve endings. Just breathing cold air can be painful for those with extremely sensitive teeth.
Gum, or periodontal, disease can cause inflammation, tooth loss and bone damage. Gum disease begins with a sticky film of bacteria called plaque. Gums in the early stage of disease, or gingivitis, can bleed easily and become red and swollen. As the disease progresses to periodontitis, teeth may fall out or need to be removed by a dentist. Gum disease is highly preventable and can usually be avoided by daily brushing and flossing. One indicator of gum disease is consistent bad breath or a bad taste in the mouth.
Bad Breath (Halitosis)
Daily brushing and flossing helps to prevent the buildup of food particles, plaque and bacteria in your mouth. Food particles left in the mouth deteriorate and cause bad breath. While certain foods, such as garlic or anchovies, may create temporary bad breath, consistent bad breath may be a sign of gum disease or another dental problem.
Canker sores (aphthous ulcers) are small sores inside the mouth that often recur. Generally lasting one or two weeks, the duration of canker sores can be reduced by the use of antimicrobial mouthwashes or topical agents. The canker sore has a white or gray base surrounded by a red border.
A bite that does not meet properly (a malocclusion) can be inherited, or some types may be acquired. Some causes of malocclusion include missing or extra teeth, crowded teeth or misaligned jaws. Accidents or developmental issues, such as finger or thumb sucking over an extended period of time, may cause malocclusions.
