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. 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 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.
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 two and four 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 dentists.
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.
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. 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.
Fluoride is a substance that helps teeth become stronger and resistant to decay. Regularyly 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.
