Dental cavities in kids can create sleepless nights for parents, especially when ignored at an early stage. Dental cavities are the most common dental problem; a dentist in Dulwich, London, states that 27.3 % of children in London get dental cavities before the age of five and common reasons behind this problem are ignoring primary teeth treatment, an unhealthy diet and poor oral hygiene practices.
In kids, primary teeth care is important because it maintains the space for permanent teeth. Early primary teeth extraction due to cavities can cause malalignment in permanent teeth. Parents can prevent dental cavities in kids by taking some measures.
Essential Tooth Brushing Tips for Parents in Preventing Cavities in Kids
Start Early as the First Tooth Erupts in the Mouth
Parents should start brushing kids’ teeth as soon as the first tooth erupts. Parents can choose a small-sized toothbrush to clean tiny teeth; giving it to the kids to hold by themselves will develop motor skills in kids and build the foundation of oral hygiene habits.
Brushing Twice a Day
Parents should introduce the habit of brushing twice a day, in the morning and at bedtime, to prevent cavities in kids. Bedtime brushing is most important because saliva flow decreases while sleeping, which naturally cleans teeth and provides protection against cavities. Morning brushing after breakfast is recommended by dentists because it prevents calculus accumulation until the next meal.
Introduce Fluoride Toothpaste in their Daily Routine
Fluoride helps in teeth remineralisation and limits cavities to the upper layer of the tooth. Parents should introduce age-appropriate fluoridated toothpaste after dentist recommendations. According to the NHS guideline for children’s teeth, the safe limit of fluoride toothpaste is 1000ppm (parts per million) for infants. Professional dentists in London also advise parents to apply pea-sized fluoride toothpaste on the brush and guide kids to spit; don’t allow them to swallow it. After tooth brushing, advise kids to thoroughly rinse their mouth with water.
Supervise Your Child Brushing
Parents’ supervision is very important to prevent dental cavities and develop good oral hygiene habits in kids. Cavities commonly develop in interdental spaces where the brush does not access easily. Parents guide kids to brush with proper technique, such as gentle circular motion, not missing the gum line to prevent food accumulation under the gums, properly rinsing the mouth, not swallowing toothpaste, brushing for at least 2 minutes, and flossing after every meal. Dentists recommend parents’ supervision from an early age till 9 years.
Lead with Examples
Kids learn easily from parents’ daily routine practice; they copy their lifestyle, oral hygiene and eating habits. As parents, you should make your daily routine- like brushing together, never missing your dental appointment and consuming a less sugary diet- these habits unconsciously become part of your kids’ lifestyle.
Essential Dietary Tips for Parents in Preventing Cavities in Kids
Limit Sugary Diet
Sugar is the main risk factor for dental decay; not only does the amount of sugar matter, but the frequency of sugar intake is also related to teeth demineralisation and the development of cavities. In kids, chocolate, cookies and candies are a common part of their lunchbox; parents can introduce healthy foods like fruits and veggies and for drinks, water and plain milk are the best options to avoid cavities in kids.
Avoid Bedtime Milk Bottles and Sweetened Drinks
Nursing bottle caries are the most rapidly developing cavities in kids. A bedtime milk bottle can hinder the natural salivary protection action, increase bacterial acid in the oral cavity through the whole night and demineralise enamel. Parents can switch kids from a bottle to a cup for milk intake or limit milk bottles at bedtime.
Don’t Introduce Sweets as a Reward
Positive reinforcement or rewarding techniques work for kids, but introducing sweets as a reward is not a good way; kids can associate the good habit with sweets. Instead, parents can give stickers, extra play time, allow them to do their favourite activity or praise them to feel proud of good habits.
Protect Your Teeth During Meals and Snacks
Parents can prevent cavities in kids by setting proper meal times. Snack-free and meal-free times are important for teeth protection; saliva neutralises the acids that are produced by oral bacteria and fermented carbohydrates from a sugary diet. It also protects the enamel from demineralisation and prevents cavities.
Essential Dental Visit Tips for Parents in Preventing Cavities in Kids
Introduce at an Early Stage
Regular dental visits play an important role in cavity prevention. Parents can develop an early dental visit habit in kids at 12 months to avoid dental anxiety in kids. Parents mostly identify cavities in kids due to pain or tooth discolouration; an expert dentist in Camden, London can easily diagnose the cavity at an early stage during regular dental visits and can also reverse the condition with preventive treatment.
Consider Fluoride Protection
In kids who are at high risk of cavity development, such as those with high sugar intake or low salivary flow, London dentists recommend fluoride treatment as a preventive measure. In this treatment, dentists apply fluoride to the teeth before cavities develop; it prevents acidic enamel demineralisation, protects against enamel loss and makes it stronger.
Don’t Wait for Toothache
Most parents plan dental visits after a toothache in their kids; at that time, cavities involve the deep part of the teeth, and dentists need to perform invasive procedures that can develop dental anxiety and fear. Regular dental visits diagnose dental problems at an early stage. Parents should visit dental professionals if children have difficulty chewing food, visible tooth colour changes, bad breath, or gum swelling; with early diagnosis, dental cavities can be prevented in kids.
Stay Vigilant
Dental cavities are the most common problem in kids; parents can prevent them by limiting sugary foods, supervising brushing, and teaching good hygiene habits by leading by example. Dentists in London recommend that parents start regular dental visits at an early age and consider fluoride protection treatment in case of high cavity risk.
