Introduction:
Oral health is a pillar of the general health, development of a child and his/her quality of life. Children have dental conditions, including tooth decay, gum disease, malocclusion, and enamel defects; they are common but can be prevented to some extent. Unaddressed they may have an impact on nutrition, speech progression, school results, self-esteem, and oral health in long-term.
This information guide describes the common conditions of the teeth in children, the onset, early signs, the effects of these conditions on health and quality of life and practical steps that can be applied that are in the form of prevention.
Taking care of their teeth is vital for the total health of every child. The most common dental disorder in kids are cavities/tooth decay, which is usually due to excessive sugar intake and inadequate tooth brushing. Also, accumulation of plaque may lead to various gum diseases viz. gingivitis which causes swollen & bleeding gums. Malocclusion is a sign that the patient may require orthodontic treatment, while excess fluoride intake can lead to a condition related to tooth dis-colouration i.e. fluorosis. Kids also can have early tooth loss from either decay or trauma and tooth sensitivity.
Objective of Dental conditions in children:
This article aims to assist the parents and the caregivers:
- Early detection of early childhood caries, dental caries, gingivitis and other oral diseases.
- Learn the development of the tooth decay.
- Get to know about the appropriate preventive methods.
- Detect, at an early stage, problems with the dentures.
- Preserve the health, nutritional, and well-being of a child.
Dental Problems Among Children.
The children can have various oral health issues that include:
- Dental caries (tooth decay)
- Early childhood caries (ECC)
- Gingivitis (inflammation of the gums)
- Malocclusion (twisted or misaligned teeth)
- Tooth discolouring (fluorosis)
- Dental fluorosis (tooth discolouring caused by an overload of fluoride)
- Tooth sensitivity
- Premature loss of teeth because of decay or injuries.
The most prevalent childhood chronic disease is tooth decay.

How Tooth Decay Starts
The process of tooth decay is well known:
- Streptococcus mutans are the bacteria that are present in the mouth.
- These bacteria develop on carbohydrates and sugars.
- There is generation of acids as a by-product.
- Acid leads to demineralization of enamel in teeth.
- This causes destruction of teeth and cavities with time.
The duration of the acid attack may take 20-40 minutes following each sugary intake, and frequency (but not quantity) of sugar consumption is more detrimental than quantity.

What Is Early Childhood Caries (ECC)?
Tooth decay in children below the age of six years is severe and is a progressive disease known as Early Childhood Caries. It is defined as:
- A lesion (cavities or non-cavities) one or more decayed.
- Missing teeth due to decay
- Filled tooth surfaces in any primary (baby) tooth.
ECC may deteriorate rapidly in case it is not observed early.

Early Warning Signs
Risk Indicators
- Primary/mother with untreated dental caries.
- Home practice of poor oral health.
Symptoms in Children
- Aversion to hot, cold or sweet food.
- Food trapped between teeth.
- Toothache or pain
Visual Signs
- Early demineralization in the form of white spots on the teeth.
- Brown or black spots
- Red, swollen, or bleeding gums
- Visible plaque or calculus
Frequent inspection of the house may assist in identifying issues.
Severe Dental Decay
As the process of decay increases, children can have:
- Persistent pain
- Dental abscess or infection
- Problem with difficulty in chewing or talking.
- Early loss of primary teeth
High stages of dental decay are usually a complicated and expensive procedure and may be done under sedation or in the case of general anesthesia.

Effects of Dental Diseases on Child Health and Quality of life
The un-treated dental issues may result in:
- Chronic pain and infection
- Eating problems and malnutrition.
- Poor weight and retarded growth.
- Speech difficulties
- Disturbed sleep
- Poor attendance and learning disabilities at school.
- Self-esteem
- Low self-esteem because of appearance/bad breath.
The health of the child directly depends on the health of the teeth, which impacts their physical, emotional and social growth.

Early Childhood Caries: Infectious?
Yes. Tooth decaying bacteria may be passed on as a caregiver to a child mostly via saliva.
How Transmission Happens
- Sharing spoons or utensils
- Using the mouth to clean the pacifiers.
- Sharing food or drinks
Reducing Risk
- Good oral hygiene should be observed by the caregivers.
- Sharing of saliva should be avoided.
- Keep toothbrushes separate

Oral Health and Infant Feeding Habits
Eating habits are significant in dental health issues prevention.
Recommended Practices:
- The breastfeeding is promoted.
- Always make sure that a child is not taken to bed with a bottle holding milk or juice.
- Present cup drinking towards the first birthday.
- Regular bottle feeding is replaced by using a spoon and katori.
Diet and Sugar Consumption: Parents Information
The type of food that children eat does not only influence their dental health; the timing of eating also has an impact on dental health.
When eaten in large amounts, high-risk foods are associated with increased risk factors
- Jalebi and other sweets
- Chocolates
- Chips and Kurkure
- Sugary drinks and juices
Practical Tips
- Limit between‑meal snacks
- Drinking water after sweets helps reduce acid exposure
- Have a day dedicated to treats (sweet bank concept)
- Look at moderation, but not total restriction.
Preventing Saliva Exchange
In order to minimize the transmission of bacteria:
- Sharing of toothbrushes and utensils is not permitted.
- Pacifier or in spoons should not be licked and then given to a child.
- Do not allow children to put fingers of the caregivers in their mouths.

Awareness on Oral Hygiene in Children
Cleaning Baby Teeth
- Wipe down the first tooth using moist cloth or cotton.
- Parents are supposed to lift the lip of the child every month to examine whether it has white or brown spots.
Brushing Guidelines
- Below 2 years of age; smear or swipe of toothpaste fluoride.
- 2-5 years of age: Fluoride toothpaste.
- Use a soft-bristled toothbrush.
Correct Brushing Technique
- Soft back and forward and down up movements.
- Brush slowly and thoroughly
- Oversee brushing till the child learns the right skills.

Take home message
- The baby teeth are very significant just like the permanent teeth.
- Decay itself may develop to severe infection and chronic complications.
- Tooth decay needs the presence of the teeth, germs and carbohydrates.
- Dental issues in early childhood can be prevented.
- Timeline the initial visit to a dentist by a child by the time they are one year old or when the first tooth erupts.
